What if It's All Been a Big Fat Lie?
New York Times ^ | 9 July 2002 | GARY TAUBES

Posted on 07/09/2002 11:00:48 AM PDT by sourcery

If the members of the American medical establishment were to have a collective find-yourself-standing-naked-in-Times-Square-type nightmare, this might be it. They spend 30 years ridiculing Robert Atkins, author of the phenomenally-best-selling ''Dr. Atkins' Diet Revolution'' and ''Dr. Atkins' New Diet Revolution,'' accusing the Manhattan doctor of quackery and fraud, only to discover that the unrepentant Atkins was right all along. Or maybe it's this: they find that their very own dietary recommendations -- eat less fat and more carbohydrates -- are the cause of the rampaging epidemic of obesity in America. Or, just possibly this: they find out both of the above are true.

When Atkins first published his ''Diet Revolution'' in 1972, Americans were just coming to terms with the proposition that fat -- particularly the saturated fat of meat and dairy products -- was the primary nutritional evil in the American diet. Atkins managed to sell millions of copies of a book promising that we would lose weight eating steak, eggs and butter to our heart's desire, because it was the carbohydrates, the pasta, rice, bagels and sugar, that caused obesity and even heart disease. Fat, he said, was harmless.

Atkins allowed his readers to eat ''truly luxurious foods without limit,'' as he put it, ''lobster with butter sauce, steak with bearnaise sauce . . . bacon cheeseburgers,'' but allowed no starches or refined carbohydrates, which means no sugars or anything made from flour. Atkins banned even fruit juices, and permitted only a modicum of vegetables, although the latter were negotiable as the diet progressed.

Atkins was by no means the first to get rich pushing a high-fat diet that restricted carbohydrates, but he popularized it to an extent that the American Medical Association considered it a potential threat to our health. The A.M.A. attacked Atkins's diet as a ''bizarre regimen'' that advocated ''an unlimited intake of saturated fats and cholesterol-rich foods,'' and Atkins even had to defend his diet in Congressional hearings.

Thirty years later, America has become weirdly polarized on the subject of weight. On the one hand, we've been told with almost religious certainty by everyone from the surgeon general on down, and we have come to believe with almost religious certainty, that obesity is caused by the excessive consumption of fat, and that if we eat less fat we will lose weight and live longer. On the other, we have the ever-resilient message of Atkins and decades' worth of best-selling diet books, including ''The Zone,'' ''Sugar Busters'' and ''Protein Power'' to name a few. All push some variation of what scientists would call the alternative hypothesis: it's not the fat that makes us fat, but the carbohydrates, and if we eat less carbohydrates we will lose weight and live longer.

The perversity of this alternative hypothesis is that it identifies the cause of obesity as precisely those refined carbohydrates at the base of the famous Food Guide Pyramid -- the pasta, rice and bread -- that we are told should be the staple of our healthy low-fat diet, and then on the sugar or corn syrup in the soft drinks, fruit juices and sports drinks that we have taken to consuming in quantity if for no other reason than that they are fat free and so appear intrinsically healthy. While the low-fat-is-good-health dogma represents reality as we have come to know it, and the government has spent hundreds of millions of dollars in research trying to prove its worth, the low-carbohydrate message has been relegated to the realm of unscientific fantasy.

Over the past five years, however, there has been a subtle shift in the scientific consensus. It used to be that even considering the possibility of the alternative hypothesis, let alone researching it, was tantamount to quackery by association. Now a small but growing minority of establishment researchers have come to take seriously what the low-carb-diet doctors have been saying all along. Walter Willett, chairman of the department of nutrition at the Harvard School of Public Health, may be the most visible proponent of testing this heretic hypothesis. Willett is the de facto spokesman of the longest-running, most comprehensive diet and health studies ever performed, which have already cost upward of $100 million and include data on nearly 300,000 individuals. Those data, says Willett, clearly contradict the low-fat-is-good-health message ''and the idea that all fat is bad for you; the exclusive focus on adverse effects of fat may have contributed to the obesity epidemic.''

These researchers point out that there are plenty of reasons to suggest that the low-fat-is-good-health hypothesis has now effectively failed the test of time. In particular, that we are in the midst of an obesity epidemic that started around the early 1980's, and that this was coincident with the rise of the low-fat dogma. (Type 2 diabetes, the most common form of the disease, also rose significantly through this period.) They say that low-fat weight-loss diets have proved in clinical trials and real life to be dismal failures, and that on top of it all, the percentage of fat in the American diet has been decreasing for two decades. Our cholesterol levels have been declining, and we have been smoking less, and yet the incidence of heart disease has not declined as would be expected. ''That is very disconcerting,'' Willett says. ''It suggests that something else bad is happening.''

The science behind the alternative hypothesis can be called Endocrinology 101, which is how it's referred to by David Ludwig, a researcher at Harvard Medical School who runs the pediatric obesity clinic at Children's Hospital Boston, and who prescribes his own version of a carbohydrate-restricted diet to his patients. Endocrinology 101 requires an understanding of how carbohydrates affect insulin and blood sugar and in turn fat metabolism and appetite. This is basic endocrinology, Ludwig says, which is the study of hormones, and it is still considered radical because the low-fat dietary wisdom emerged in the 1960's from researchers almost exclusively concerned with the effect of fat on cholesterol and heart disease. At the time, Endocrinology 101 was still underdeveloped, and so it was ignored. Now that this science is becoming clear, it has to fight a quarter century of anti-fat prejudice

If one doesn't eat red meat, weight will not likely be a problem.

Not to worry, a quarter century of drug prejudice prevails in light of science. The government plans to move forward with a plan to end self destructive behaviors like taking drugs and eating wrong. We will soon have helicopters flying over to force the cattle growers indoors.

Eating approved food will become a right. The government will establish a dietary protection agency in which all the properly approved beans and rice will be equally available. After all it is the government's duty to protect us from what we ingest. Eating fat might hurt my family if I die and leave my children to suffer.

Red meat does not put weight on you...hydrogenated fats (as in margarine and processed baked goods),corn syrup (which is in every processed food),and simple carbs (white flour and starch) are what does.

What's forgotten in the current controversy is that the low-fat dogma itself is only about 25 years old. Until the late 70's, the accepted wisdom was that fat and protein protected against overeating by making you sated, and that carbohydrates made you fat. In ''The Physiology of Taste,'' for instance, an 1825 discourse considered among the most famous books ever written about food, the French gastronome Jean Anthelme Brillat-Savarin says that he could easily identify the causes of obesity after 30 years of listening to one ''stout party'' after another proclaiming the joys of bread, rice and (from a ''particularly stout party'') potatoes. Brillat-Savarin described the roots of obesity as a natural predisposition conjuncted with the ''floury and feculent substances which man makes the prime ingredients of his daily nourishment.'' He added that the effects of this fecula -- i.e., ''potatoes, grain or any kind of flour'' -- were seen sooner when sugar was added to the diet.

True. I remember asking my dad when I was a kid why so many poor people were fat, and he told me it was because they couldn't afford meat and ate mostly starchy foods. That was just common sense back in the days before the junk food/junk science alliance convinced Americans that carbs were good for you and meat was bad.

You are right. The Atkins diet works great for some of us. Lost forty pounds, cholesterol is great, heart is great, feel great, and best of all, have kept the weight off for two years and counting. No bread, no rice, no noodles, no sugar, no taters, no sugar, no fast food!

Sorry. Works for me. And trying (for the most part) to keep kosher with poultry, fish and dairy (incl. cheese).

Best to you.

Lost 60 in three month without even trying. We'd go out to eat and I would eat MORE than everyone and lose, lose, lose. My blood work came back after six months and my doctor was STUNNED! Chol 310 -> 150, Lipids 900 -> < 100. That was more than a year ago. From time to time I still put on a pair of 46 pants to remember how big I was. ha, ha, ha!

The poorer you are, the more likely your fat. More than 60% of young ladies on public assistance are over weight.

Did either of you have intense cravings for sugar when you started, and if so, for how long? That was my problem last time I went on the Atkins.

Almost. Extra calories put fat on you. Meat requires a lot more energy to metabolize than simple carbs do. More carbs=more calories. If you take in more than your body can use, you will put on weight.

Atkins works by filling you up on things that are harder to digest, there-by evening out the caloric debt load.

Lean heavy on the meat. Stay clear of most procesed foods. Drink plenty of water. Maintain good variety.

Easy-peasy.

You can't find a single study to bear that out.

The beginning of the diet is the toughest part because you're pulling your body off carbs. When I go back onto the induction phase (read the book if you don't remember this) I'm usually hungary for a day or so. To curtail this I drink a ton of water and eat salads, hard meats, celery or mushrooms dipped in ranch of course!

Here's the deal. I've known since my body building and power lifting days (long since past) that if I eat a big "healthy" breakfast-- toast, fiberous cereals, fruits, skim milk--I'd be starving by lunch, but if I abstained from breakfast, I'd not be hungry until mid afternoon and then just a little. Why? All of those things listed above are loaded with carbs that cause blood sugar levels to spike, then droop. Sagging blood sugar levels trigger hunger. So many of those health things CAUSE hunger later in the day.

This IS the difference between Atkins and most other diets--NO HUNGER after your initial phase. If I get hungry, then I'm cheating.

Just one more thing. If you're trying to do this without reading the book--DON'T! You need to understand what's happening in your body.

P.S. I no longer take my high cholesteral meds. My doctor said he has never recommended that before, but I have no need for them anymore.

Then maybe you could tell me why I have many overwieght vegetarian friends, and a couple of others who tell me that they just can't lose their extra weight.

Then it would follow that high-fiber foods such as whole-wheat breads and country-style orange juice would be helpful also.

Aaargh! That sounds intolerable. No bread nor rice? If true, I know why I'm not losing weight, but jeez, that doesn't sound like a very appealing diet...
