Flat tummy . . . or, Why your dietitian is fat

When I go to the hospital, I am continually amazed at some of the hospital staff: 5 ft 4 inch nurses weighing over 200 lbs, etc.

But what I find particularly bothersome are some (not all) hospital dietitans--presumably experts at the day-to-day of healthy eating--who waddle through the halls, easily 40, 50, or more pounds overweight. It is, to say the least, credibility-challenging for an obese dietitian to be providing nutritional advice to men or women recovering after bypass or stent while clearly not in command of nutritional health herself.

What's behind this perverse situation? How can a person charged to dispense "healthy" nutritional information clearly display such clear-cut evidence of poor nutrition?

How would you view a success coach dressed in rags? Or a reading coach who can barely read a sentence?

Easy: She follows her own advice.

Hospital dietitians are essentially forced to adhere to nutritional guidelines of "official" organizations, such as the American Heart Association and the USDA. There is some reason behind this. Imagine a rogue dietitian decides to advocate some crazy diet that yields dangerous effects, e.g., high-potassium diets in people with kidney disease. There is a role for oversite on the information any hospital staff member dispenses.

The problem, of course, doesn't lie with the dietitian, but with the organizations drafting the guidelines. For years, the mantra of hospital diets was "low-fat." More recently, this dated message has begun--only begun--to falter, but now replaced with the "healthy, whole grain" mantra. And that is the advice the hapless dietitian follows herself, unwittingly indulging in foods that make us fat.

Sadly, the "healthy, whole grain" message also contributes to heart disease via drop in HDL, increased triglycerides, a huge surge in small LDL, rise in blood sugar, increased resistance to insulin, tummy fat, and diabetes. Yes, the diet provided to survivors of heart attack increases risk.

The "healthy, whole grain" message also enjoys apparent "validation" through the enormous proliferation of commercial products cleverly disguised as healthy: Cheerios, Raisin Bran, whole grain bread, whole wheat pasta, etc. The "healthy, whole grain" message, while a health disaster, is undoubtedly a commercial success.

I'll bet that our fat dietitian friend enjoys a breakfast of healthy, whole grains in skim milk, followed by a lunch of low-fat chicken breast on two slices of whole grain bread, and ends her day with a healthy meal of whole wheat pasta. She then ascribes her continually climbing weight and size 16 figure to slow metabolism, lack of exercise, or the once-a-week piece of chocolate.

Wheat has no role in the Track Your Plaque program for coronary plaque control and reversal. In fact, my personal view is that wheat has no role in the human diet whatsoever.

    Dr. Davis,

    In your clinical practice, do you see good results from patients who continue to eat oats and/or brown rice as long as they cut out sugar, wheat and corn?  

    I ask because Dr. Weston Price's research found examples of cultures that used these grains (oats and rice) while continuing to exhibit signs of good health. He did not have access to modern diagnostics however, so perhaps he missed some indicators.

    Kind regards,

    Each time I contemplated seeking advice from a dietitian, I changed my mind after I saw the dietitian and decided I was doing well enough on my own.  Never felt like I could believe or trust dietary advice from someone whose BMI was obviously higher than my own.

    And I love my new flat stomach.

    I don't think that overweight dieticians (and nurses, and doctors)even follow their own advice. Not that that advice isn't garbage anyway, but I doubt that whole grains and lots of fruit and lean meats make up the bulk of their diets. It's probably more the case that these people aren't following the rules they give their patients (not that the rules would work, anyway). "Knowing" something and choosing to do it are two different things. I completely agree with you on sugar and wheat, but that doesn't mean I'm not going to indulge without guilt during the holidays (I don't have any health problems, though.)

    It's like with smoking. People KNOW it's bad for them, but they still do it. I know several doctors who tell their patients to quit smoking, but who smoke like chimneys themselves. I used to work with a PULMONARY PATHOLOGIST who was a chain smoker.

    Mediterranean diet (the real deal) is very good if you are a peasant in agricultural job doing hard work (4.000 Kcal/day). Than you can eat your pound or two a day of bread plus salami, cheese and olive oil and fruits, be full, lean and healthy.

    You move to city, start to work in an office, cut all to 2.000 kCal/day proportionally and you find yourself hungry, gaining fat and lacking minerals and vitamins with the same diet.

    I've seen more fat doctors than fat dietitians. I'm a dietitian and I'm at a perfect body weight, AND I follow my own advice, which is to eat in moderation. This is an extremely unfair stereotype to make. Between doctors and nurses thinking they know all about nutrition with minimal education in it, and patients asking for advice and then telling you that you're wrong right to your face, it's no wonder clinical nutrition has such a high burnout rate and low rate of job satisfaction.

    I'm a fat dietitian, and we fat dietitians know how much we are hated.

    I find it interesting that the topic of "dietitians that follow their own advice" had to be written with such contempt. Consider the message your readers came away with...many commented on their contempt of fat people rather than grasping the diet advice you are promoting. "A naughty post" BMI 22 wrote. Why naughty? Because ridiculing someone for being fat is still acceptable behavior in this part of the world, even though we know we should not "throw stones". Consider promoting your message without inciting the contempt of others.

    In addition, consider how being fat can't be hidden, the way other characteristics can. For example, what physical characteristics are required of a realtor, plumber, grocery clerk, insurance salesperson? It might not matter if they were fat since they are not dispensing "health" advice, but consider all of the unseen ways they might deviate from the norm.

    I'm a dietitian as well, and although not "fat", I find it challenging to maintain weight. This not because of any "bad" advice I'm giving, it's just the way life is sometimes.

    That said---I hope that someday you are publicly ridiculed for something you struggle with. I hope you are ridiculed for your imperfections, which I'm sure you have. Dietitians aren't any more perfect than anyone else. Just because we understand the physiology behind things doesn't mean that life is any easier for us. Maybe the "fat dietitian" in the hallway has things going on in her life that you don't know about, and you should keep your "fat" mouth shut about it.

    I'm 69 and have been on Atkins, level one, for a little more than eleven years.  I now consider myself a "former" overeater because as long as I remain below twenty grams of carbs per day, I'm totally in control of my eating.  Even after eleven years I understand that my chances of ever being able  to eat more than 20 grams of carbs per day will never happen!  Like an alcoholic, whenever I reach my "carb limit" I have to stop at that point.  I can't eat even a single bite of any grain products without "falling off the wagon".  A single bite of bread or pizza crust and I become an alcoholic with food!  I'm just amazed that more dietitians  are not overweight eating grains.  Anyone who can eat grains and still remain under 400 pounds has my admiration.

    This information is for the dietitian who suggested eating in moderation.  Is this the same advice we give to an alcoholic?  Do we tell them to drink in moderation?   About the only advice an over eater receives from a doctor or dietitian is:  Starve yourself for the rest of your life and don't forget to kill yourself exercising!  Now we all know that these may not be their exact words, but trust me that is exactly what an over eater hears just before going into “full panic mode”.  When my eating was “totally out of control”, I had as much chance of stopping at one slice of bread as a “down and out” alcoholic has of stopping after one drink!  Until we all understand this, there is almost no long term hope for a “fat” person.  We do not suggest that an alcoholic drink in moderation for a very good reason.  How can we advise someone with a major eating disorder to eat the very foods they are addicted too.  Had I not given up whole grains, fruit and any high carb vegetables, I would now be 400 pounds.  I learned this thanks to Dr. Atkins.  If not for him I wouldn't be here now.  How many 400 pound, 69 year old men do you know?  Moderation of grains/alcohol will never work.

Lipoprotein(a), menopause, and andropause

Lipoprotein(a), menopause, and andropause

Lipoprotein(a) is a curious lipoprotein. Not only is it a genetic pattern with numerous variations, it is also one that shows a predictable age-dependent rise.

Women in particular are prone to this effect, men to a lesser degree. As we age, many hormones recede, particularly growth hormone, testosterone, the estrogens (estradiol, estriol, estrone), progesterone, and DHEA, among others. This is not a disease but the process of senescence, or aging.

When we're young, estrogens, testosterone, and DHEA all exert suppressive effects to keep lipoprotein(a), Lp(a), at bay. But as a woman proceeds through her pre-menopausal and menopausal years, and as a male passes through his fourth decade, there is an accelerated decline of these hormones. As a result, Lp(a) crawls out of its cave and starts to sniff around.

Typically, a woman might have a Lp(a) of 75 nmol/l (approximately 30 mg/dl) at age 38. Ten years later, at age 48, her Lp(a) might be 125 nmol/l (app. 50 mg/dl), all due to the decline of estrogens and DHEA. A parallel situation develops in males due to the drop in testosterone. For this reason, it may be necessary to re-check Lp(a) once after the fourth decade of life if you've had a level checked in your younger years.

This opens up some interesting therapeutic possibilities. If receding hormones are responsible for unleashing Lp(a), hormones can be replenished to reduce it. In males, this is relatively straightforward: supplement human testosterone and Lp(a) drops about 25%.

In women, however, it's a bit murkier, thanks to the negative experince reported using horse estrogens (AKA Premarin) in the HERS Trial and Women's Health Initiative. You'll recall that women who take horse estrogens and progestins (synthetic progesterone) do not experience less heart attack and develop a slightly increased risk of endometrial and breast cancer. There was, however, a poorly-publicized sub-study that showed that women with Lp(a) experience up to 50% fewer heart attacks on the horse/synthetic combination.

Wouldn't it be nice to have a large trial examining the safety/advisability of human estrogens and progesterone? To my knowledge, no such confident study in a significant number of women exists, since there's so little money to be made with human hormonal preparations.

For these reasons, we use lots of DHEA, generally at doses of 25 to 50 mg per day. It makes most people feel good, boosts energy modestly, increases muscle, and reduces Lp(a) up to 18% in women, a lesser quantity in men.

Is skinny necessary for reversal?

Is skinny necessary for reversal?

Nothing we do in the Track Your Plaque program guarantees that coronary atherosclerotic plaque or your heart scan score is reduced or reversed.



But everything we do weighs the odds in your favor of successfully achieving reversal: correction of lipoprotein patterns, uncovering hidden patterns like Lp(a), vitamin D, being optimistic--it all tips the scales in your favor.

But how necessary is it to be skinny, meaning somewhere near your ideal weight?

It is important, but not as important as it used to be. Let me explain.

I used to tell people that plaque would not regress unless ideal weight was achieved and all the parameters of abdominal obesity and metabolic syndrome were corrected. This includes blood pressure, blood sugar, low HDL, small LDL, high triglycerides, and high c-reactive protein. Curiously, though, as we've gotten better and better at reducing coronary calcium scores, I've been finding that complete correction of all parameters, including achieving ideal weight, don't seem to be as necessary to achieve plaque reversal.

I almost hate to say this, but I've even witnessed significant drops in heart scan scores in people with body mass indexes (BMI) of 30--obese.

The necessary change doesn't seem to be weight, per se, but the consequences of weight. In other words, if you remain overweight, but blood sugar, HDL, small LDL, etc. have shown substantial improvement, then reversal is still achievable.

Then is it okay to be fat or overweight?

Reducing weight to ideal weight does indeed tip the scales in your favor, since it represents an observable, perceptible measure of all associated patterns. Dropping weight can also minimize the need for efforts to correct the consequences of overweight--you might need less niacin, fish oil, exercise, blood pressure medication, etc. to succeed at plaque reversal. Achieving ideal weight may also provide benefits like reduced risk of cancers and degenerative diseases of the hips and knees. But, to my recent surprise over the last two years, achieving ideal weight is not an absolute requirement to achieve reversal.

This is contrary to what some others say. For instance, in an upcoming interview with Dr. Joel Fuhrman on the Track Your Plaque website, Dr. Fuhrman argues that 10% body fat for males, 22% body fat for females, accelerates plaque and symptom reversal. Dr. Fuhrman is author of Fasting and Eating for Health, Eat to Live, and a new upcoming 2-part book, Eat for Health, and proponent of high-nutrient vegetarian diets and fasting. Dr. Fuhrman has been helpful in teaching us some important lessons on how to apply periodic fasting to accelerate plaque reversal.

So, which is it, fat or skinny?

If given a choice (which everyone has), I'd choose skinny. But, provided all the parameters associated with overweight are corrected, then remaining overweight doesn't necessarily mean that you can't still succeed at plaque reversal.

If you are interested in knowing what your ideal weight is, there are a number of software calculators and tables available, including the HealthCentral.com calculator and the National Heart, Lung, and Blood Institute BMI Calculator.

    It all falls in line with obesity being another marker for an overall metabolic condition, not being the *cause* of the metabolic condition.  

    The biggest disservice the medical establishment has done is ignore the evidence of this and continue to prescribe a diet that just makes it all worse and worse.

    Hi Dr Davis,

    Another cracking post. It reminds me distinctly of a long discussion on Dr Bernstein's site as to whether weight loss to ideal weight is needed to normalise blood sugars in a type 2 diabetic. You appear to be looking at another aspect of the metabolic syndrome, IHD. And it appears to be quite obvious that weight loss, per se, is irrelevant to both IHD and normoglycaemia, PROVIDED you normalise the problems described as the metabolic syndrome.

    Furnham and fasting is equally interesting. One has to ask; what happens during fasting? A full water fast to might be expected to give up to a kilo of weight loss each week perhaps? I've never tried this, but would guess this is reasonable. With flat-line basal glucose and insulin levels. That's just under 150g/d of weight loss, of which perhaps at least 100g/d is body fat. Mostly palmitic acid with some palmitoleic thrown in.

    The fat does not just evaporate. This is what a person's metabolism runs on during fasting. Mostly saturated fat. And fasting is excellent for plaque reversal, we're told. And I believe it.

    The question to me is, what would happen if you replaced that lost fat, by mouth, with similar fat (palmitic and palmitoleic, ie lard) to produce weight stability? Would you continue reversal without fasting? Perhaps throwing in 50g/d high quality protein to stop muscle loss.

    Obviously anyone on a low fat diet, needing to maintain weight stability, requires a high carbohydrate intake with its associated and inevitable post prandial hyper-insulinaemia. No insulin, no glucose uptake. We need calories to live. 1000kcal of lettuce needs insulin for every molecule of glucose it releases. Once a low fat vegan has lost their palmitic acid based excess weight, they'll be right back on to glucose based metabolism.

    Fasting is fat fueled. It works for reversal. Whether from your adipocytes or your plate, it's the same palmitic acid.

    Hi, Peter-

    Interesting thoughts.

    It makes me wonder again whether there are ways to accelerate the process of plaque reversal. While we typically achieve it in a 12-18 month long timeline, could it be achieved in a less than 4 week period? Could we do so by using specific nutrient manipulations during fasting?

    I don't know, but I'm hoping that we can inch towards some insight towards this process.

    Anonymous,

    If I could just clarify my own opinion:

    A vegan on a water fast, after the first 2 days, is living on animal fat and animal protein. Their own. They will obviously die if they continue, although possibly without arteriosclerosis (makes you think of Pritkin). Supplying that same person with 150g of lard and 9 whole eggs (biologically eggs are the highest value protein according to the WHO) per day will provide the same metabolic conditions as fasting without the fasting, weight loss or muscle loss. The question then is whether this will continue the rapid reversal of arteriosclerosis. That is open to debate, and no doubt we all will have our opinions. I invite the use of logic. I've said before, I visit here as Dr Davis is open to ideas which do not necessarily tally with his own. That's good.

    Dr. Davis,

    I'm not a doctor or a scientist so what do I know?  nothing...  And I'm probably not going to restate Peter's argument very well.

    But it seems to me that in the rethinking of diet that you're engaged in, partially triggered by the Taubes book, you're going to need to address this argument that Peter makes.  I had never heard that argument before but I can't think of an escape from the logic of it, namely:

    1) during fasts, plaque regresses, 2) during fasts, body fat (which Peter says is mostly saturated fat) is used to provide energy, but 3)  how could plaque regress if a metabolism running on saturated fat was harmful to that regression process?

    It would be very interesting to hear what Dr. Fuhrman thinks about this too.

    Of course, fatty acids do not just enter and exit cells passively depending on concentration gradients, but do so under the control and influence of a number of factors.

    Nonetheless, I think we are onto something, this idea of "enhanced fasting" to achieve accelerated reversal. Hmmmm....

    Just a thought, don'T know if its related or not....When people stalled out on weight loss Atkins suggested a fat FasT for 4 or so days eating macadamina nuts,olives, egg salad with whole fat mayo,even a few T OF OLIVE OIL.It seemed to reboot the metabolism...don't know about plague reversal but it stopped hunger and people started to lose again, he said not too do this until the plateau was a month long, I cant recall exact time frames.
    Its so contrary to what we have been led to beleive but if I knew it would reverse my plague I would do it, but would have to see how to balance BG, maybe have to go off glucopaghe while doing it and monitor lots.

    I read your new special report at  Track Your Plaque that is an interview with Dr. Fuhrman on fasting and had some thoughts.

    I confess that my head is still spinning by the argument that Peter has made in his comments to this post.

    When I first read Peter's argument, it reminded me more than anything else of the first paragraph of Gary Taubes' NYT Magazine article a few years back when he described the irony that would be many doctors standing naked in Times Square moment:

    Dr. Fuhrman, an ardent vegan, promotes fasting as a helpful solution for reducing plaque without realizing and surely without understanding that the reason the solution works is because it amounts to increased animal fat consumption.

    I have to say that I'm completely unimpressed by any explanation or theory Dr. Fuhrman's put forward, either in his first book or in his interview with you, about WHY fasting works to regress plaque or at least reduce angina symptoms.

    Am I missing something and he actually can and does explain why it works?

    Peter, on the other hand, has put a theory on the table about why it works that could be tested, right?  Or has it already been tested?

    If and when the moment comes when a lot of doctors are standing naked in Times Square, I'm going to be there with a camera.  lol

    The other aspect in common between fasting and a very low-carb diet are the ketones. It might be that the ketones are responsible for a bettering of heart condition as it is most efficient fuel we can use.

    There is a difference though between them, one is catabolic the other is anabolic, so they may not be exactly equivalent.

    Excellent point

    Yasiwaya points out that ketosis restores the mitochiondrial function lost in insulin resistance, best quote:

    "The ability of a physiologic ratio of ketone bodies to correct most of the metabolic defects of acute insulin deficiency suggests therapeutic roles for these natural substrates during periods of impaired cardiac performance and in insulin-resistant states"

    Some of the other papers by this author, available in full text by hitting "related links" suggest a deep in depth knowledge, but they're way beyond me.

    For those of us who long ago abandoned the cholesterol hypothesis, hyperinsulinaemia and insulin resistance are the driving forces of IHD. The Yudkin/Stout camp. Ketosis appears to side step insulin resistance, be that in the myocardium or the cells of the arterial media. I would wholely agree this is a useful step in IHD and may well be where the benefits come from.

    Peter, I would use butter, ghee, or beef fat instead of lard (2-4% PUFA vs 12%). You're wrong that eating a high lard diet would be the same as fasting. On a fast, you don't eat a gram of PUFAs. 150g of lard has 18g of PUFAs. 150g of beef tallow has 3 to 4.5 grams, or 1/4 to 1/6 as much as lard. Ruminant animals are best. Also, eggs are unnecessary. You can eat fat from meat, butter, and some organ meats every now and then. The eggs have more than PUFAs than beef and butter fat. To really reproduce the fasting state, I would keep the PUFAs as low as possible (3-4g).

    Fasting induces autophagy, a process that recycles cellular structures that range in size from proteins to organelles. It's central to many processes of biological repair.

    Research in autophagy is growing very fast, and must be relevant here.

    (BTW, niacin and other antilipolytic agents also induce autophagy.)
