Wheat Belly Revisited

Do you have a wheat belly?

When I first coined this phrase back in July, 2007, I had witnessed the phenomenal health effects of wheat elimination in several hundred patients.

In the nearly two years that have passed since my original post, I have witnessed hundreds more people who have done the same: eliminate pretzels, crackers, breads of all sorts, bagels, pasta, muffins, waffles, pancakes, etc.

If anything, I am convinced now more than ever that wheat is among the most destructive foods in the human diet. At least 70% of people who eliminate wheat from their diet obtain at least one, if not several, substantial health benefits.

Now, if I were trying to sell you something, say, an alternative to wheat, then you should be skeptical. If I tell you that drug or nutritional supplement X is great and you should take it, only to follow it with a sales pitch, you should be skeptical.

What am I selling? Nothing. I gain nothing by telling everyone to avoid wheat. In fact, I wish it wasn't true. Wheat foods taste good. Wheat flour makes great comfort foods. In years past, I spent many hours sitting at the bagel shop reviewing papers over a cup of coffee and a bagel. No longer.

So here, back by popular demand, the original Wheat Belly post:



Wheat Belly

You've heard of "beer bellies," the protuberant, sagging abdomen of someone who drinks excessive quantities of beer.

How about "wheat belly"?

That's the same protuberant, sagging abdomen that develops when you overindulge in processed wheat products like pretzels, crackers, breads, waffles, pancakes, breakfast cereals and pasta.



(By the way, this image, borrowed from the wonderful people at Wikipedia, is that of a teenager, who supplied a photo of himself.)

It represents the excessive visceral fat that laces the intestines and triggers a drop in HDL, rise in triglycerides, inflames small LDL particles, C-reactive protein, raises blood sugar, raises blood pressure, creates poor insulin responsiveness, etc.

How common is it? Just look around you and you'll quickly recognize it in dozens or hundreds of people in the next few minutes. It's everywhere.

Wheat bellies are created and propagated by the sea of mis-information that is delivered to your door every day by food manufacturers. It's the same campaign of mis-information that caused the wife of a patient of mine who was in the hospital (one of my rare hospitalizations) to balk in disbelief when I told her that her husband's 18 lb weight gain over the past 6 months was due to the Shredded Wheat Cereal for breakfast, turkey sandwiches for lunch, and whole wheat pasta for dinner.

"But that's what they told us to eat after Dan left the hospital after his last stent!"

Dan, at 260 lbs with a typical wheat belly, had small LDL, low HDL, high triglycerides, etc.

I hold the food companies responsible for this state of affairs, selling foods that are clearly causing enormous weight gain nationwide. Unfortunately, the idiocy that emits from Nabisco, Kraft, and Post (AKA Philip Morris); General Mills; Kelloggs; and their kind is aided and abetted by organizations like the American Heart Association, with the AHA stamp of approval on Cocoa Puffs, Cookie Crisp Cereal, and Berry Kix; and the American Diabetes Association, whose number one corporate sponsor is Cadbury Schweppes, the biggest soft drink and candy manufacturer in the world.

As I've said many times before, if you don't believe it, try this experiment: Eliminate all forms of wheat for a 4 week period--no breakfast cereals, no breads of any sort, no pasta, no crackers, no pretzels, etc. Instead, increase your vegetables, healthy oils, lean proteins (raw nuts, seeds, lean red meats, chicken, fish, turkey, eggs, Egg Beaters, low-fat yogurt and cottage cheese), fruits. Of course, avoid fruit drinks, candy, and other garbage foods, even if they're wheat-free.

Most people will report that a cloud has been lifted from their brains. Thinking is clearer, you have more energy, you don't poop out in the afternoon, you sleep more deeply, some rashes disappear. You will also notice that hunger ratchets down substantially. Most people lose the insatiable hunger pangs that occur 2-3 hours after a wheat-containing meal. Instead, hunger is a soft signal that gently prods you that it's time to consider eating again.

You will also make considerable gains towards gaining control over your risk for heart disease and your heart scan score, a crucial step in the Track Your Plaque program.

    I've lost most of my wheat belly by eating as you suggest. But it seems like there is a last little bit that won't go away, plus I have "wheat breasts". Is there a reason these things don't go away quickly (especially the breasts), and is there something else I can do?

    ok, but what is the mechanism?

    Please explain why wheat is a problem food.  I am not looking for clinical trials, just a plausible theory that I can align with or not.

    Although I don't impose the burden of data on you, here are a few references with ample data showing remarkable statistical evidence for benefits to vegetarianism:-

    I appreciate your point here, but...

    I've been strictly wheat-free since the start of the year (I've slipped up a bit when I've forgotten to pack my own soy sauce for a sushi outing, and there's probably been some "stealth wheat" in infrequent restaurant meals...otherwise nada). I have some sort of wheat-related enteropathy that provides a strong incentive to be strict. I do eat some non-wheat grain products, but not every day. My sugar intake is also not perfect, but it's still much improved over any point in 2008.

    So I should be looking pretty good about now, right? Well, no. My weight seems to have stabilized down about 5-7lb below my previous stable weight, but any changes from that baseline have been strictly upward (mostly water retention after weight lifting). My waist measurement is unchanged. If there's any legitimate loss (beyond water weight due to the lower carb diet) it hasn't come off there. I'm quite overweight, so this is really a tiny drop in the bucket.

    This near-total lack of improvement has been achieved with a schedule of 4+ hours of intense exercise most weeks.

    So, anyway. Not asking for help, just commenting that the picture is not necessarily as rosy as you depict.

    I agree with what you say about wheat. I feel much better when I omit it from my diet.

    However, I do have a question. Previous generations ate wheat without having the dire health consequences we have now. Was this due to
    1. not eating nearly as much wheat as people do today? or
    2. not eating transfats and/or tons of sugar, along with the wheat? or
    3. performing hard, physical labor, something most of us don't do?
    Or, perhaps a combination of those things, plus other factors I haven't even considered.

    Before great grandpa went out to plow the fields, he probably had a breakfast of some kind of meat and/or eggs, biscuits, perhaps gravy, and then he worked really hard for hours. The kids walked to school, maybe several miles, and lunch might have been bread and butter and milk. And when they had recess, they played hard. That generation didn't have obesity and rampant heart disease. If we lived the same way our grandparents and great grandparents lived, might we be able to eat wheat products (not the super-refined junk, but what they had available), without the major health consequences?

    Healthy oils and lean proteins? That idea is derived from the Mediterranean idea which is derived from the observations of Ancel Keys, the father of the lipid hypothesis. It's pure speculation.

    It's rather contradictory. The lipid hypothesis says carbohydrate is good. Thus, we should eat wheat. Yet here you are telling us wheat is actually bad for us. Tell us to eat healthy oils, i.e. vegetable oils like olive oil and canola oil. But then tell us to eat lean meats, implying there's something bad about animal fat, i.e. saturated fat, and something good about vegetable oils, i.e. polyunsaturated fat omega 3/6/9 (without noting that vegetable oils contain many times the amount of omega 6 contained in animal fat). Ancel Keys' lipid hypothesis is based on those assumptions too.

    To cut wheat, yes. But to cut animal fat, where's the justification?

    @D: I do think exercise offsets a lot of metabolic derangement. It's part of how hockey players (the young serious ones, not slow moving middle-aged folks like me) can get away with eating shockingly poor diets.

    Incidentally, my parents tell me my grandpa had very similar symptoms to mine, before I was old enough to be aware of it myself. I have some sort of intolerance or allergy, though.

    reply to D:
    One of the problems with modern bread is the speed it's produced at.
    Starting in the early 1960's bread production was industrialised using "bread improvers". A loaf can now be turned out in just a couple of hours, whereas back in the past it was a long process. Earlier in the nineteenth century and before, bread had to 'prove' using naturally occurring wild yeasts. The time factor is important because of the somewhat indigestible properties of grain. Phytic acid and enzymes in the grain need to be neutralised with a long exposure to yeasts. This can be achieved also by soaking grains overnight or longer.
    Traditional societies prepare their grains this way to make them digestible and to get the full nutritional benefit.
    See 'Weston Price Foundation' for information for grain prep.

    "You will also notice that hunger ratchets down substantially. Most people lose the insatiable hunger pangs that occur 2-3 hours after a wheat-containing meal. Instead, hunger is a soft signal that gently prods you that it's time to consider eating again."

    My mother, and paternal grandmother were both diagnosed with hypoglycemia (low blood sugar), and were instructed to eat many small meals per day to avoid symptoms of hypoglycemia.

    I started having the same symptoms during junior high, so my mother taught me to eat many small meals to avoid my shakes, headaches, and light-headedness that happened after 3-4 hours without food (except when I ate really large meals occasionally, then I could last longer without food).

    I start following Dr. Davis' blog, and he was blogging about the benefits of fasting from some studies. I commented that I didn't think I could fast because of the hypoglycemia, and he replied to stick it out, and stop the wheat. Coincidentally, I had a borderline H1C at that time.

    But instead of sticking it out, I forced myself to not eat until my hypoglycemic signs started, then I ate veggies, meat, or fruit, with a few nuts here and there. I'd eat as little as possible, then wait until the next episode of hypoglycemic symptoms. Oh, I did continue eating rice or potatoes, but smaller servings, and quit sugar during that time.

    I started noticing I could go a little longer between meals without hypoglycemic symptoms after about 4 days, and I think it was about 7-10 days off wheat and sugar (but still eating a little rice or potatoes) when I went 16 hours without food, and no hypoglycemic symptoms.

    My follow-up HA1C was in the normal range after stretching out my meals, and stopping wheat and sugar.

    Does wheat reduction works as well (i.e. eating a slice of bread or 30 grams of pasta or breading your meat instead of eating two big bowls of pasta, a loaf of bread, a slice of pizza, several biscuits and pastries daily) or total removal of wheat from the diet is absolutely required?

    I believe that wheat and refined carbs are responsible for the 'muffin-tops' and 'wheat bellies' so many folks are carrying around now.
    I work with people who have gluten addiction all the time and when they eat a Whole foods diet free of gluten, dairy, soy, and sugar the weight falls off them quick. And onlike most other diets the weight falls off the belly first, which is an awesome motivator. Also, there aren't the constant cravings of the low fat diet. My dad went on the gluten, dairy, soy and sugar free diet plan and his blood sugar and blood pressure went from borderline diabetic/high blood pressure to optimal ranges in a few weeks. He is off all medications now and full of energy at 66 years old.

    I have been low carb for 5 years and cut out wheat from my diet completely. No pasta, no breads of any kind, no breading on my meat, no waffles/pancakes/donuts/etc or any grains at all. I also cut out potatoes and corn.

    I dropped down from 190 to 135, a normal weight for my height, and I have kept it off for 4 years. I completely believe that the grains we eat now are so far removed from what they used to be  (due to refining processes, selective breeding to be more tasty, etc) that they have become a slow acting poison.

    And I wish there was a law that would prevent the 'ignorant gene' from being passed down from parents to children...

    Thank you Dr. Davis for bringing this to light.  It would seem plausible that genetically modified grains have contributed significantly to our modern illnesses...most notably, inflammation, diabetes and the dramatic rise in the incidence of celiac disease.  As grains have been "pushed" into our daily diets since the 1970's (think low fat, whole grain nonsense), T-2 diabetes has increased exponentially!  And while there is no 'one-size-fits-all' DIET, if the USDA Food Pyramid (the definitive guide on how to eat healthy!) was so great with its ongoing drumbeat of  "EAT MORE GRAINS!", then wouldn't we have LESS diabetes...LESS obesity...and wouldn't we all be slim and healthy?  I guess this is the reason why the standard American diet has the acronym: SAD...

Butter and insulin

Butter and insulin

In a previous post, Atkins Diet: Common Errors, I commented on butter's unusual ability to provoke insulin responses. I offer this as a possible reason why, after a period of effective weight loss on a low-carbohydrate program, inclusion of some foods, such as butter, will trigger weight gain or stall weight loss efforts.

This develops because of butter's insulin-triggering effect, doubling or tripling insulin responses (postprandial area-under-the-curve). If insulin is triggered, fat gain follows.

Here's one such study documenting this effect: Distinctive postprandial modulation of ß cell function and insulin sensitivity by dietary fats: monounsaturated compared with saturated fatty acids

López et al 2008


From Lopez et al 2008. Mean (± SD) plasma glucose, insulin, triglyceride, and free fatty acid (FFA) concentrations during glucose and triglyceride tolerance test meal (GTTTM) with no fat (control), enriched in monounsaturated fatty acids (MUFAs) from refined olive oil (ROO meal), with added butter, with a mixture of vegetable and fish oils (VEFO) or with high-palmitic sunflower oil (HPSO). N = 14.

The postprandial (after-eating) area-under-the-curve is substantially greater when butter is included in the mixed composition meal. This effect is not unique to butter, but is shared by most other dairy products.

Fat, in general, does not make you fat. But butter makes you fat.

    I wander if the effect is due to the milk solids or the type of fatty acids. If it is the milk solids making ghee will solve the problem.

    3/19/2010 5:54:39 PM |

    So the low fat control meal of pasta and bread gives the LEAST amount of insulin response!

    So, to avoid insulin spikes you must minimize all types of fats.

    Fat+Pasta seem to trigger the insulin.  The glucose response does not seem to matter all that much.

    Is it correct to say, in view of the graphs, that this type of dairy-induced insulin elevation is not mirrored by blood glucose readings, so we couldn't check for it at home with a glucose meter?

    butyric acid causes an insulin response, as does casein...interestingly, although i can't find it, i saw a paper that showed the insulin response to white bread was actually less when combined with butter...

  • daniel the smith

    3/19/2010 6:06:21 PM |

    What if you eat it without any carbs (e.g., like I do with my eggs in the morning)? If there's nothing to trigger the insulin in the first place, butter can't make it worse, right? Or am I wrong?

  • Lucy

    3/19/2010 6:16:20 PM |

    That's an interesting study indeed.  It seems to indicate that eating no fat at all (the control meal) provided better results in every category except glucose rise, and then it was only with the rest of a fairly tight pack.  Adding any fat at all spiked the insulin significantly higher.   This is consistent with the charts in your post "The Timing of Blood Sugars".  Yet you concluded there that carbohydrates should never be consumed without fat.  Based on these studies, it sure looks like a person is trading a little glucose rise for a larger insulin spike when consuming fat.  Which begs the question, which is worse?  Does insulin cause more problems than glucose?   You did say it was the insulin that triggered weight gain...

    I remain unconvinced that I should rush out and follow Ornish.

  • Diana Hsieh

    3/19/2010 6:34:54 PM |

    Interesting post -- and my experience confirms it.  Here's something that I recently posted to the OEvolve e-mail list:

    As folks might know, I've been struggling with my weight due to my hypothyroidism.  Even though many of my symptoms have improved, I continued to gain weight at the very consistent rate of 3 pounds per month.  Sometimes, mostly due to a bit of fasting, I'd be down a pound or two, but then I'd suddenly gain back all that weight plus more within a day or two, so that I'd be on that steady upward slope again.  

    In late February, I was up to just over 150 pounds; that was my pre-paleo weight.  That's not so terrible in and of itself -- although I hated it -- but the continued upward progression was really alarming.  Plus, I'd outgrown almost all my pants!

    After listening to Robb Wolf talk about the growth-promoting, insulin-spiking effects of dairy, I realized that I'd been eating a huge amount of dairy lately -- far more than ever before.  I've been buying those huge blocks of cheese from Costco, not to mention those delectable half gallons of cream.  So instead of eating meat-and-veggie leftovers for lunch, I was usually eating some high-fat dairy.  And for breakfast, I would eat cheese rather than meat with my eggs.  

    A few weeks ago, I decided to cut my dairy down dramatically -- to basically just one serving per day at most.  So I'll have a cup of raw milk kefir or cheese on meatza, but not much more than that.  That was really hard for me to do for the first week, as I really was used to eating it as a staple.  I'm also not eating nuts, absent some "must have food as I run out the door" emergency, as I know they can hamper weight loss for me.

    The results have been good so far.  I've not gained any more weight in the last two weeks.  Instead, I've lost four pounds.  Given what I had been experiencing, that's pretty remarkable.

    I'm not sure how much more weight I'll lose just due to cutting back the dairy.  I definitely think my metabolism isn't quite up to speed yet due to the hypothyroidism. However, my experience suggests that eating boatloads of dairy -- even good-quality, high-fat dairy -- is an excellent way to gain weight.

    That being said, I don't think that it's necessary to cut out all dairy to lose weight.  I'm still eating some dairy, and I'm losing weight.  Plus, I lost my original 18 pounds with my 1.5 shares of raw milk -- that's 1.5 gallons per week.  (I'm now down to just 1/2 shares, meaning 1/2 gallon per week.)  I just think dairy is something to consider reducing if you're not meeting your weight loss goals.

    ***

    I've not lost much more weight since writing that, but I'm definitely not gaining any weight.  That's huge: I was petrified that I'd be 200 pounds by next summer.  

    I've probably stalled in that weight loss because my metabolism is still screwy due to my not-yet-fully-managed hypothyroidism.  Plus, I'm not seriously trying to lose weight right now: I don't want to stress my already over-stressed body.  But perhaps cutting out dairy entirely would make a difference.

    Anyway, thanks for putting some science behind my experience, Dr. Davis!  I'll definitely add a link to it in the discussion of dairy on the principles page of Modern Paleo.

    Could butter still make you fat if you're eating below BMR?  It seems to me that if you were eating 1000 calories per day consisting of only butter, and your BMR was 1800, you would still lose weight.  Is there anything that scientifically proves this to be false?

    Dear Dr Williams, I find this topic very interesting, but being a lay person would like to know a bit more. What would the "meal" they talk about be? Would that be grains? Is the resuls they got from combining grains with cream or butter? Would butter or dairy products have the same effect in the absence of grains?

    3/19/2010 9:35:38 PM |

    Doesn't this study mainly show that butter is a bad idea when eaten together with lots of carbs?

    Is it really likely you would get the same insulin response if the butter was eaten without all that carbs?

    Interesting.

    But the meals were carb-heavy, too.

    "The subjects then ingested, within 15 min, a fat-rich meal consisting of dietary fat [50 g/m2 body surface area of butter, refined olive oil (ROO), high-palmitic sunflower oil (HPSO) or a mixture of vegetable and fish oils (VEFO) along with a portion of plain pasta (30 g/m2 body surface area), one slice of brown bread, and one container of skim yogurt.

    I wonder if the same effect would be noted if were JUST butter, or oil.

    Is it the butter? Or the wheat pasta, brown wheat bread and lactosey yogurt?

    Interesting. Here are the numbers from the study for insulin AUC:

    19960 +- 2766 control
    27970 +- 2107 VEFO
    29619 +- 4975 MUFA
    34749 +- 1167 HPSO
    37582 +- 4364 SFA (butter!)

    Unless I've misread the study, the "control" meal has no fat at all, and is not isocaloric with the test meals. "the macronutrient profile was as follows: 72% fat, 22% carbohydrate, and 6% protein (see Table S1 under "Supplemental data" in the online issue). The subjects also consumed the same test meal containing no fat as a control meal". So the butter test meal has nearly 4x as many calories as the control meal. The AUC for insulin between the two is about double for the butter, but that seems like a useless measure.

    Comparing like-for-like, the spread between average insulin AUC for butter meal and the isocaloric alternate fat meals  shows the butter to be about 34% higher than VEFO and only 8% higher than HPSO. (I have to be pedantic here and point out the spread between averages is not as good as would be the average spread, but I can't get that unless I have the raw data from the study.)

    If you want to claim that butter has some unique ability to raise insulin vs. other fats, this is not strong support.

    You say "butter's insulin-triggering effect, doubling or tripling insulin responses", and "butter makes you fat". I don't see support for either claim when I read that study.

    I'm not an MD nor a research scientist. But decades ago, I was a math major. If I read the study and do my math right, the subjects ate an 800 kcal meal of which 72% was fat, for 576 kcals worth of fat (the other control meal components were pasta, bread, and skim milk yogurt).

    576 kcals worth is nearly 6T of butter -- or 3/4 of a stick! To me, that is important additional context for the increased AUC for both the insulin and the triglycerides.

    Considering my typical use (~1T/meal) and considering the potential downside of replacing carb calories with more PUFAs (and omega 6s -- even 1T of EVOO has over 1g of omega 6), I'm not ready to throw out my ghee just yet.

    I think that you should eat butter . . . in small quantities and occasionally. I do not believe that the data argue for liberal use every day, or else you chance triggering insulin. Remember: It's the interpretation of the data in the context of the broader experience that leads you to practical conclusions.

    So let me get this straight: Ingesting carbohydrates including the bad guy wheat does not do much to blood glucose levels and insulin response. But adding fat to the mix at least doubles, or, in the case of butter, quadruples the peak insulin response? That seems like the best refutation of all the low carb/paleo/primal/ef approaches I've ever seen. So where is the catch?

    If you eat fat, ASP levels will rise, which will make you gain fat. ASP levels increase in response to an oral fat load, and ASP is one of the most potent stimulant of triglyceride synthesis.

    So, if you eat carbs, insulin secretes and you store it as fat, if you eat fat, ASP levels rise and you store it as fat. Why is it only the insulin's fault?

    "Fat, in general, does not make you fat. But butter makes you fat."

    This seems wrong. When I eat more butter, I lose fat/weight. Eat more carbs, gain fat/weight. Been noticing this for years. Sure, put a load of butter on noodles or rice, and you'll gain plenty, but just keep the carbs low and there's no problem. This seems like a case of being blinded by science. Maybe the science isn't exactly wrong, but just incomplete or misapplied.

    After reading your post and the hyperlipid post I'm left with a few questions.

    1.The big one, why is butter raising insulin so much? I had previously thought it was only high GI carbs that did that. Hyperlipid seems to think it was the small amounts of casein.

    2.Is it right to say that since the control carb meal only contained 174 calories compared to the butter meal which contained 800 this study is fairly useless? It raises some interesting questions but you can't conclude anything until you have a proper control containing the same amount of calories.

    3. Are there any studies which measure insulin secretion after a pure butter meal with no carbs?

    Even though the study is inconclusive, I'm lowering my butter consumption until I'm sure it isn't causing an agrovated insulin response. Even though butter causes much higher levels of FFA's which mean more of the fat is being burned, insulin levels that high can't be healthy

    Dr. Davis,

    I'm not too sure this is right.  I don't have the time to hunt down the links right now, but there was a study on Swedish children recently that showed those eating full-fat dairy (butter fat) were leaner than those who ate low-fat dairy.  Also, butter contains a lot of CLA, which is now being sold as a fat-loss supplement.  I can't parse this study on its own merits like Peter or Pyker (though I thank them for doing so), but I remain unconvinced.  

    I also agree with other posters about the in-vivo, long-term evidence of dairy-reliant cultures and their longevity.  

    Again, with so many cautions of what not to eat, I'd love to see a Dr. Davis-approved diet plan.  If I were just following all the Don'ts, I'd go crazy (and hungry).

  • Anonymous

    3/20/2010 5:39:12 PM |

    The palmitic acid content of the butter would probably trigger  insulin when there is an abundant source of glucose in a meal.  But, if you look at this post by Stephan you will see that the body stores dietary fats when there is a glucose source of energy available.  

    http://wholehealthsource.blogspot.com/search/label/fats

    As the glucose is depleted the fat is released to be used as energy.  The graph in Stephan's post clearly shows the cycling that occurs in normal metabolism.


    The information Dr. Davis presented showed an insulin spike, not continual high levels of insulin that would inhibit the release of FA as an energy source.
    I believe it was Dr. Eades who recently posted about the constant exchange of fats in and out of storage, and the implication is that storage is only a problem when cells remain saturated with glucose.  The fat never comes out because it isn't needed.  In this scenario insulin resistance and fat storage is protective.

    http://high-fat-nutrition.blogspot.com/2010/03/getting-fat-is-good-official.html

    My understanding of this subject is, by limiting carbs, especially the sugar surrogates that are refined grain products, you can keep the normal cycling of energy sources going.

    When everything is working right, your body signals hunger and satiety appropriately, and the body runs at an equilibrium level of energy intake and energy expenditure.

    I suspect that the FA composition of butter makes it available as an energy source sooner than the other FA's tested in the study.  Hence the higher insulin level.


    I don't see where a moderate amount of butter, when there is a limited or low availability of glucose sources will make you fat, expecially if you are VLC or on a ketogenic diet.  I can see where it could be a problem if you were eating 150 or more grams of carbs per day and have metabolic syndrome.  Then high levels of insulin would spike even higher prompting the liver to pump out more glucose, and the fat just has no where to go except into storage.

    Take your vitamin D3 to get your adiponectin levels up.  Take fish oil while limiting Omega-6's to normalize inflammatory responses. Limit carbs, and get the glucose-FA cycle working for you.

  • Nigel Kinbrum

    3/20/2010 6:19:20 PM |

    Eating carbs with butter produces a big insulin response because butter induces temporary insulin resistance (IR) which means that more insulin has to be secreted to get the same net effect. Looking at the blood glucose response, the net effect is the same. So stop panicking. The temporary IR lasts for only a few hours.

  • Gretchen

    3/20/2010 7:49:28 PM |

    "Fat, in general, does not make you fat. But butter makes you fat."

    If you based your conclusion on the graph in this study, all fats make you fat.

    Protein also stimulates insulin, so protein makes you fat.

    Carbs stimulate insulin, so carbs make you fat.

    Conclusion: Food makes you fat.

    It's known that fatty acids acutely stimulate insulin synthesis. With chronic exposure to fatty acids (as occurs in obesity), insulin synthesis is blunted.

    I've never understood the body's rationale for this, unless a sudden infusion of fat makes it think it had better store the fat for the future, but with chronic stimulation it figures it has enough.

    I don't know how ingested fat is related to fatty acids in the blood, whether or not this is linear.

    Whatever, it doesn't look to me as if butter is much different from the other fats, and as others have pointed out, the amounts used in this study (on top of about 44 g of carb, which I wouldn't call a low-carb meal) were enormous.

    The other odd thing is that usually fats slow down a carb-stimulated blood sugar peak, and they didn't in this study.

  • Neil

    3/20/2010 10:33:31 PM |

    This is what is considered 'butter' in the study you refer to above Dr Davis and ultimately what this study uses to prove its point:

    "The subjects then ingested, within 15 min, a fat-rich meal consisting of dietary fat [50 g/m2 body surface area of butter, refined olive oil (ROO), high-palmitic sunflower oil (HPSO) or a mixture of vegetable and fish oils (VEFO) along with a portion of plain pasta (30 g/m2 body surface area), one slice of brown bread, and one container of skim yogurt]."

    Yep, that would be my definition of 'butter' as well!

    If that pile of c**p didn't raise your insulin levels what would?

    In addition: "The average total energy provided by the meals was 800 kcal (10 kcal/kg), and the macronutrient profile was as follows: 72% fat, 22% carbohydrate, and 6% protein"

    Only 22% carbohydrate, no chance of that increasing insulin levels either I suppose!

    It has to be the 'butter'

An intake of fat fish once a week was associated with higher serum concentrations of n-3 fatty acids. The intake of saturated fat and full fat milk were inversely associated with BMI."

    The study was made at the University of Gothenburg.

    Looking at insulin alone can be very misleading. If glucagon is released along with the insulin ,as happens when eating protein, then the fat storing effects of insulin are negated.

    For low carbers, the study is meaningless as it was done with lots of carbs. I will continue to eat butter and cheese until I see a meaningful study that shows that they cause a real problem.

    I saw it, and was hoping to discuss it in the pro-D blogosphere.

    I have two ideas why this might be the case.

    (1)  Because people of African descent are adapted to live nearer the equator, where the sun is all you need for enough vitamin D, they may not be as adapted as Europeans to use dietary vitamin D (supplements being an analogue), which Europeans probably relied on during winter months.  Thus, too much supplemental vitamin D may be harmful to African Americans, at least in the case of arterial calcification.  (I hedge, because I've also read recently that African American children with low D status have higher rates of asthma. http://www.sciencedaily.com/releases/2010/03/100317112055.htm)

    (2) There is also the possibility that somewhat different dietary patterns between European Americans and African Americans may offer some explanation.  I can't imagine what this might be, but maybe something having to do with vitamin K2, which helps prevent calcium deposits in the arteries?  There are two possibilities here:

    (a) Maybe African Americans consume (or produce in the gut - from eating greens, a traditional part of the African American diet) more K2 than European Americans, and this is why they have less arterial calcification with lower D status - they don't need the D as much for arterial health, and more dietary D just upsets the balance.

    (b) Maybe they eat less K2 than European Americans (maybe eat less hard cheeses?), and thus vitamin D supplementation, which may require a certain level of K2 to be beneficial, might be harmful instead.

    This sentence leads me to believe it's more likely to be (a):  "Despite these lower vitamin D levels and dietary calcium ingestion, blacks naturally experience lower rates of osteoporosis and have far less calcium in their arteries."  The strong bones and clear arteries make me think African Americans may have better K2 status.  

    It's possible that vitamin A status also plays a role.

  • Helen

    3/21/2010 8:56:30 PM |

    Another thought on the question of African Americans and vitamin D - perhaps *because* they consumed less calcium their vitamin D requirements were lower, so the supplemented amounts were excessive.

  • Dr. William Davis

    3/21/2010 9:55:55 PM |

    The point is not whether glucagon is stimulated. That is, in my view, immaterial.

    The point is that your poor, tired pancreas, likely operating at a fraction of its original beta cell capacity from the years of the beating it took while you ate Cheerios and Cocoa puffs, ate sandwiches, and drank Coca Cola with your pizza, is being stimulated to produce more insulin.

  • Nigel Kinbrum

    3/22/2010 9:05:25 AM |

    Regarding calcification, I think that Helen has hit the nail well & truly on the head regarding Vitamin K2. "If it calcifies, think K2" is what I always say (along with "If it spasms, think Magnesium").

    Taking large amounts of Vitamin D3 and nothing else probably exposes deficiencies in the other fat-soluble vitamins A, E & K2.

    Having cured Lumbar osteoporosis in three years using Ca, Mg, D3 & K2 (and no Alendronate), I will never stop taking Ca, Mg, D3 & K2.

    Why eat carbs together with fat?
    They ate 44 g glucose which means the P-glucose could reach >48 mM without insulin i 70 kg person. Of course the disaster hormone insulin increases to block all lipolysis as well as proteinolysis to try to burn off all the totally unnecessary carbohydrates they added.
    If contol diet (gluose) did not change glucose and thus insulin level it must be fake.

    When I'm low-carbing, a favorite meal is a tenderloin cooked medium-rare, sliced thin, and dipped in butter.

    I lose weight anyway.

    Also, what kind of butter was used in the study?  Was it regular grocery-store butter, or was it organic and/or grass-fed butter?  The FDA claims there's no difference between dairy produced with rBGH and dairy produced without, but I'm given to understand that rBGH-produced dairy has higher levels of IGF-1.  What would be the effect on insulin of all that exposure to insulinlike growth factor?

    And I'll second Miki's question of whether the milk solids wouldn't make a difference.

    And to the person who mentioned "all that lactose-y yogurt"--if you make yogurt correctly, it should have hardly any lactose in it at all.

    I suspect that the FA composition of butter makes it available as an energy source sooner than the other FA's tested in the study. Hence the higher insulin level.

    Fatty acids by themselves don't prompt insulin release.  Protein does (but the insulin is balanced out by glucagon), and of course carbs do, but there's nothing inherently dangerous in a fatty acid that would prompt the body to store it away immediately.

    It seems like no one has a handle on how the metabolic parts fit together to make the whole. My experience from converting from whole grains and no-fat dairy to full-fat dairy has been weight loss and increased energy, particularly after eating a selection of artisan cheese. I often get up, have a bowl of full-fat yoghurt or kefir with 100% chocolate nibs and fresh-roasted nuts, then sample several artisan cheeses, and go cycling 44 km before getting back to make everyone else breakfast. My body seems geared to fat as fuel and I never get blood sugar lows. If this is raising my insulin, it apparently does not affect my blood sugar.

    Usually, I learn all I need to from Dr. Davis' posts.  My thanks to the other contributors today for illustrating that context is everything.  We have reason to believe that dairy from the industrial food chain would not be as good a food as if we could get true grass fed dairy cow products - but this seems out of context with other info I've seen which shows only moderate insulin response to dairy fats.  Bottom line: measure the markers which indicate insulin levels over time as a gauge of whether your diet does/doesn't work (unless you are losing weight - in which case, you know it is working).

    It seems that whatever butter does to my insulin levels, this does not curb the very positive effects I experience from eating butter. When I cut carbs and replaced them with generous amounts of cream and butter (organic preferably) I lost 14 kg. Moreover, when in "carb country", i.e. airports, airplanes, trains and the like, I can keep my energy up by eating the small amounts of butter and cheese available. Butter also has a way of keeping me feeling full for a very long time. This implies that the fat is not stored away in my fat cells but instead made available for burning. Perhaps other people are more sensitive.

    I still prefer coconut oil for fat loss used in a no-carb diet. I'll find that ghee, which I've also tried, isn't so effective for weight-loss perhaps because it's not so fatty. But it does have to be in a no-carb diet, not a low-carb one. Everyone's got a switch which is triggered by carbs, but no-one knows where it is, not exactly. So unless a study is rabidly no-carbs, none at all, I don't really see what can be learned.

    your response to the commentors seems to indicate that butter will make you fat IF you have abused your body with carbohydrates because of a compromised pancreas.  I am willing to suppose this could be true, but what about people who his ave not abused their bodies, what about children being raised low carb from the start, would butter be fattening for them?  Your response would lead me to believe your answer will be no.  I really appreciate your blog and recommend it to all, but please clarify this issue.  Maybe a whole new blog on this would be a good idea, since the entire low carb community is talking about it.

    To everyone else I have to say there is nothing like testing something for yourself.  If you have an insulin tester, have some butter and test yourself and make a chart.  See how YOU are affected.

    The postprandial (after-eating) area-under-the-curve is substantially greater when butter is included in the mixed composition meal. This effect is not unique to butter, but is shared by most other dairy products.

    Um... Sorry... I see the data differently.
    In the fat meals in the study, the amount of fat intake was the same, yet butter delivers higher serum FFAs, indicating that fat might stimulate lipolysis, even though it appears to induce a short term insulin spike.
    Carbohydrate might promote a lower insulin response, but it blocks lipolysis.
    Finally, there's a lot more going on here than just insulin.  To take it out of context is meaningless.

    but my question is what is the reason behind this insulin triggering effect of butter? can anyone answer this?

    It's always good to challenge deeply held beliefs in case we are wrong. I do have a soft spot for butter and hope it is an outlier as far as blood glucose.

    As people know, I've been struggling with my weight due to my hypothyroidism. Although many of my symptoms have improved, I kept the weight gain in very consistent rate of 3 pounds per month. Sometimes, mostly due to a little fast, would be a pound or two, but then suddenly I would like to recover all that weight plus more than a day or two, so it would be in this constant uphill again.

    I'm stunned by your absolute condemnation of butter based on this one study.  Geez, have you been paid off by Wesson or Crisco?   You need to consider all the confounding variables in this study.  Your blog post should be retracted and/or rewritten.  This is very disappointing after your carefully researched examination of wheat.

    In my experience, butter and butter fat are good for you.  I have lost considerable body fat and gained much muscle this year on an eating plan that involves a lot of raw milk and cream from grass-fed cows, 3 to 4 glasses of milk and up to a cup of cream per day.  Butter fat is not making ME fat, quite the opposite.

    Insulin goes down faster because the vegetable fats are stored in the fat tissue faster..

    There is another problem with that study - people do not keto adapt in 8 hours - it takes 4- 6 weeks to fully adapt to a low carb diet.

    Once adapted, low-carbers are BETTER able to clear FA as the liver revs up it's fat metabolic capabilities.  Low carbers also tend to eat less frequently - reducing the exposure to both BG and FA - only when both are elevated do we see the pronounced toxic effects of the fats.

Restaurant eating: A fructose landmine

Restaurant eating: A fructose landmine

There is no remaining question that fructose is among the worst possible things humans can consume.

Followers of the Heart Scan Blog already know this, from conversations like The LDL-Fructose Disconnect, Where do you find fructose?, and Goodbye, fructose.

But fructose, usually as either high-fructose corn syrup (44%, 55%, occasionally higher percentage fructose) or sucrose (50% fructose), is ubiquitous. I've seen it in the most improbable places, including cole slaw, mustard, and dill pickles.

It's reasonably straightforward to avoid or minimize fructose exposure while eating at home, provided you check labels and focus on foods that don't require labels (like green peppers, salmon, and olive oil, i.e., unprocessed foods). But when you choose to eat at a restaurant, then all hell can break loose and fructose exposure can explode.

So what are some common and unsuspected fructose sources when eating at a restaurant?

Salad dressings--Dressings in all stripes and flavors are now made with high-fructose corn syrup and/or sucrose. This is especially true of low-fat, non-fat, or "lite" dressings, meaning oils have been replaced by high-fructose corn syrup. It can also be true of traditional non-low-fat dressings, too, since high-fructose corn syrup is just plain cheap.

Olive oil and vinegar are still your safest bets. I will often use salsa as a dressing, which works well.

Sauces and gravies--Not only can sauces be thickened with cornstarch, many pre-mixed sauces are also made with high-fructose corn syrup or sweetened with sucrose. Barbecue sauce is a particular landmine, since it is now a rare barbecue sauce not made with high-fructose corn syrup as the first or second ingredient. Sauces for dipping are nearly always high-fructose corn syrup-based.

Ketchup--Yup. Good old ketchup even is now made with high-fructose corn syrup. In fact, you should be suspicious of any condiment.

Highball, Bloody Mary, Margarita, Daiquiri, beer--Even the before-dinner or dinner drink can have plenty of fructose, particularly if a mix is used to make it. While Blood Marys seem the most benign of all, adorned with celery, pickle, and olive, just take a look at the ingredient label on the mix used: high-fructose corn syrup.

Fructose is a stealth poison: It doesn't immediately increase blood sugar; it doesn't trigger any perceptible effect like increased energy or sleepiness. But it is responsible for an incredible amount of the health struggles in the U.S., from obesity, to diabetes, to hyperlipidemias and heart disease, to arthritis, to cataracts.

    I can't believe that there is so much high fructose corn syrup in all these foods. Thanks for the information!

    I question the importance here. If you've already eliminated the major offenders like sweet drinks and desserts, is the amount of fructose you're likely to consume from sources like restaurant salad dressings really likely to do any more damage than, say, the ethanol in the glass of wine you drink with dinner 4 or 5 times a week?

    Also, Heinz now makes a non-HFCS ketchup ("Simply Heinz"), not that subbing sucrose for HFCS really buys you much from a health perspective.

  • Ed Terry

    Proponents of HFCS state that it's no worse than sucrose.  However, the physical properties of HFCS allow it to be used in a lot more foods than sugar.

    I could go on about the amazing, appalling corruption of our ssystem of government but the fact the government promotes and subsidizes bad food for the benefit of a tiny portion of the population has to be one of the worst examples.

    Apple harvest, before refrigeration, was consumed as cider. The more alcoholic it got the less residual fructose it had.

    "An apple a day keeps the doctor away" is a relatively new rhyme. Old heirloom tree stock yields pretty sour apples; we've bred them to be sweeter.

    Fructose is far worse than previously suspected. It is, in my view, a large part of the reason so many Americans are obese, diabetic, with all the complications of these conditions.

    A few milligrams per day from fructose is likely of little to no consequence. But a little here, a little there and it all adds up. Ketchup, salad dressing, a couple of pieces of fruit, some "organic agave nectar" on your dessert, an you've had a substantial exposure.

    Let the belt out a notch or two.

    It's definitely a drag that so much of the food you get in a restaurant now is doused in sugar to match most peoples' tastes, to say nothing of the fact that everything is also cooked in refined vegetable oils!

    Beer does not contain (more than trace) fructose. It does contain significant dextrose and starch in excess of what is found in wine/whiskey.

    How much fructose did a caveman on average consume? Does anyone know?

    Some of the cooked vegetables at restaurants (especially tomato sauce and diced tomatoes) also typically come from cans with BPA linings.

    MSG is also pretty common with restaurant food. I once saw a guy at a Chinese place carrying a 50 lb sack of MSG into the back door. Yes, it comes in bulk. Most horrifying food-related sight I have ever seen, and trust me, Chinatown has some pretty horrifying food-related sights. But it's not just Chinese food. MSG is everywhere.

    Re: fructose and average cavemen. "Average" is meaningless. But during berry season, I wouldn't be surprised if 60% of the calories were from berries, so 30% of calories each from fructose and glucose, with dried meat or fish making up the other 40%. Have you ever been in the mountains of Washington during August? Incredible numbers of wild blueberries, slightly smaller than the ones in stores but just as tasty. The Indians of that area preserved blueberries in salmon oil, so they would be available year-round.

    Humans are clearly designed to process fructose as 30% or more of daily calories, just like our ape ancestors. Whether this amount of fructose contributes to longevity or not is another story. Evolution needs us to bear and raise healthy offspring, which requires living to age 40 or so. After that, we are no longer needed, and evolution might even want us to get out of the way after age 40.

    Just wondering about "cave men" and their kin .... It seems their epoch's realtors
    pitch about cave sites being all about location, location, location determined who got the best pickings.

    I don't think the hunting was all so easy for them. Cavemen had to share any game brought down; a fellow needed to feed his gun bearer and give his trucker some.

    For them it was probably hieracrchial portion of the kill and seasonal wild pickings. Mostly allaying hunger with rationed dried meat and what they dug up or stripped from plants.

    When the cave far from water it might mean progressive dehydration spells. Many may very well have been experiencing protracted disassociation brain chemistry states.

  • Davide Palmer

    Dr. Davis,

    Yet, in my opinion, I still think there is a substantial difference between consuming natural fructose and HFCS.

    For example, an apple contains polyphenols, flavanols, fiber, and other various anti-inflammatory substances that work synergistically together to buffer the some of negative effects high blood glucose.

    Pure HFCS, on the other hand is highly processed from genetically modified corn, void of any buffering nutrients and very high in reactive aldehydes and ketones(which cause serious oxidative stress and inflammation).

    --Big difference, here

    A high consumption of HFCS has, through numerous studies, been clearly implicated in numerous conditions such visceral fat, insulin resistance, fatty liver and obesity, etc. A high consumption of natural fruit has not.

    A just think this distinction should be made more clearly. Just my opinion.

    Hi Davide Palmer,

    Would you please elaborate on ketones? I am assuming it's about the context wherein they occur.

    I was taught ketones are the heart's preferred fuel.
    One Doctor who uses cocconut oil for Alzheimers says we fortuitously convert it into ketones.

    your correct about the problems of BBQ sauce. i have eliminated most of the HFCS from my diet...except for BBQ sauces. the best tasting one in my opinion is Sweet Baby Rays but its loaded with HFCS, and lots of sodium. KC Masterpiece is marginally healthier and less appetizing. Any recommendations for a readymade sauce?

    As one of many out there who suffers from Fructose Malabsorption, I can tell you it is a very hard substance to avoid!  Garlic, onions, apples, pears are very high in fructose and everyone has their own personal threshhold for tolerance.

    I wonder how this factors into overall health issues such as cardiovascular disease, IDDM etc.?
