Pushing my dieting button

If you see me post articles or rants about my anti-diet views, don't be sure that I'm directing them at you in particular. I know of at least three people on my friends list who are on Weight Watchers, and at least a few others who are doing various things to maintain or lose weight.

I may scroll through your posts about your diet plan, or I may comment occasionally if I feel compelled, too, but make no mistake: I do not support your diet. I won't try to sabotage your efforts, but I will state here and now that I think you are doing something that can potentially have very bad effects on your mental and physical health.

Dieting doesn't work. The odds are 9-1 against you that you'll keep the weight off and there's a good chance that you'll end up fatter. Chances are that you'll have to keep going on diets to maintain your weight or lose the weight you've re-gained, and yo-yo dieting is extremely unhealthy.

You may think you deserve to know what it's like to be in a thinner body, but it's most likely a pipe dream. There's no good evidence that you can modify your body shape to a signifcant extent (more than about 10 percent of your original body weight) and maintain that new shape. (For the record, I've been on Weight Watchers twice. The first time, I lost 41 pounds. The second time, I lost 36 pounds. I gained it all back.)

Health gurus are always going on about the conditions that are exacerbated by excessive weight, and they assume that losing weight will improve the condition. But there are NO good studies about whether long-term weight loss will improve your health because such a tiny minority of people who lose a large amount of weight are able to keep it off for more than a year or two.

There are, however, many studies that show that chronic dieting makes your heart health, blood pressure, and other measures of health WORSE.

Dieting causes compulsive eating habits. A weight-loss diet is just a doctor-approved eating disorder. I would not try to aid you in your efforts to be a bulimic or an anorexic, and I do not support your efforts to develop an eating disorder, which is what weight-loss dieting is, when you strip off all the pretenses.

Everyone I've ever known who has gone on a weight-loss regimen has become completely obsessed with food. Weighing food, measuring food, thinking day and night about what fits the plan and what doesn't. It's just like the mentality of the friends I've known who are anorexic and are constantly measuring what they eat and thinking all day about what they can and can't eat.

Do I support teaching yourself more about nutrition? Sure! Do I support the idea that Americans have a distorted sense of what a reasonable portion of food is? Sure! Do I support improving your eating habits to include more fiber, fruit, and vegetables and less processed food? Sure! But if your focus is on losing weight regardless of how the method will affect your long-term health, I can't support that.

I'm especially leery of commercial weight-loss plans, because it is not in their best interest to see you succeed, because then you will not keep paying them your hard-earned money. Their bottom line is making money, not your health. Did you know that Weight Watchers has a policy that if you're five pounds over your MINIMUM weight, they will help you lose weight? That means if they decide your optimum weight range is 108 to 128 pounds, and you come in weighing 113 pounds, they will help you lose weight until you're 108 pounds. If health was their focus, they would tell a woman who is 120 pounds and who wants to be 114 pounds to see a psychiatrist about her distorted body image instead of telling her they can help her lose those "last six pounds."

I'll continue to post anti-diet rants and articles about studies which point out the destructiveness of dieting, so if that bothers you, you may want to scroll on through. . .

I also think you're being too hard on health issues. Yes, certainly weight loss that occurs in an unhealthy and unsustainable way can lead to the health problems you've described. But are you really suggesting that people suffering from certain health problems (I'm thinking especially insulin-related disorders such as diabetes and PCOS) can't benefit from healthy, sustainable weight loss?

No, what I'm saying is that for the average person, permanent weight loss of any significant magnitude is virtually impossible. It's like the doctor saying, "You know, your diabetes would be better if you could be a mermaid instead of a human."

"OK, doc, I'll try to be a mermaid, but I'm not sure if it's sustainable long-term. I can only hold my breath for 90 seconds."

There's good data that exercise, *regardless of weight loss*, helps with insulin issues, especially if it's muscle-building exercise, because the more muscle you have, the better you process insulin.

You can use the "eat when hungry, stop when full" approach that the Overcoming Overeating people advocate even if you have diabetes.

Is it weight loss itself or following a healthy weight loss plan that's virtually impossible? Or some combination of the two?

Significant weight loss (more than 10 percent of starting body weight) AND maintenance, via calorie-control, is generally unsustainable:

http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B758G-48KMC8J-8&_coverDate=04%2F30%2F1996&_alid=311664971&_rdoc=1&_fmt=&_orig=search&_qd=1&_cdi=12926&_sort=d&view=c&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=ecc96cdd0ce046e2d1651efa30f07f34

Results At 1 year, no significant differences were noted among the three groups. The diet-only group lost 6.8 kg, the exercise-only group lost 2.9 kg, and the combination group lost 8.9 kg (P=.09). During the second year, the diet-only group regained weight — reaching 0.9 kg above baseline; the combination group regained to 2.2 kg below baseline; and the exercise-only group regained slightly to 2.7 kg below baseline (P=.36). Repeated measures analysis of variance showed a group-by-time interaction (P=.001); data for the dieting groups best fit a U-shaped regain curve (P=.001).

Applications The results suggest that dieting is associated with weight loss followed by regain after treatment ends, whereas exercise alone produced smaller weight losses but better maintenance. The large outcome variability and unequal difficulty of the regimens across groups limit the generalizability of the findings. J Am Diet Assoc. 1996; 96:342-346.

It's not like I'm making these statistics up out of thin air to support my pet theory. Even the NIH agrees that the majority of dieters gain back all the weight they lose:

http://grants.nih.gov/grants/guide/pa-files/PA-04-092.html

"Although there are many well-accepted methods to reduce initial body weight by 7-10%, long-term maintenance of that lost weight is more problematic. On average, among treatment-seeking populations, approximately 1/3 of lost weight is regained by one year; by 5 years most or all previously lost weight
is regained."

I know you're not making them up. Can't you understand why someone might be the teeniest bit resistant to the idea that they're going to be called "morbidly obese" by their doctors for the rest of their lives?

Get a new doctor. I'm "obese" as well.

"obese" is defined as being 30 percent over your so-called "ideal weight" or heavier. However, "ideal weight" is an arbitrary social construct that has little relation to health and morbidity rates based on stastistical studies.

People at the low end of the "ideal" BMI range have worse mortality rates than people who are in the "mildly overweight" BMI range, for instance.

I realize that sounded flip and callous. What I'm trying to say is that 1. I understand the feeling but diets won't solve the problem and 2. don't take bullshit from your doctor.

I had an old gynecologist tell me that my dysmenorrhea (or however you spell the word for bad periods) was from me being fat. Um, no, bitch. I had terrible periods when I was much thinner. Next idea?
