An article of greater interest to my friends trying to lose weight:

Forget fad diets. Get the facts on weight loss

This is interviews with actual researchers - selected quotes:

James O. Hill - 13 years research into successful dieters:

There's no particular diet that seems to be more effective than another one; it has more to do with individual preference - what you can stick with long-term.

The weight-loss stage lasts an average of three to six months. After six months, ... if you haven't lost all the weight you want to lose in that time, you're probably not going to do it.

Ralph La Forge studies the role of exercise in weight loss:

Why is it so hard to lose weight just by exercising?
Unless you're a serious athlete, you just don't burn that many calories.

The idea of a fat-burning zone is b.s. In order to burn only fat, you would have to go at such a slow pace that you'd burn only two to three calories per minute.

Barry M. Popkin is the director of the University of North Carolina Interdisciplinary Obesity Program

It’s the size of snacks, not meals, that has changed substantially over the past 20 years.

What's the final verdict on low-carb diets?
They might help some people lose weight, since people do tend to eat fewer calories on that kind of restrictive system. But it's almost impossible to maintain that way of eating over the long haul.


What are dieters' most common psychological pitfalls?
They try to do everything all at once

Are there psychological traits that distinguish successful dieters from people who lose and regain over and over? The successful ones monitor themselves and they develop solutions to common problems.


Louis J. Aronne researches how the body regulates weight and how hormones and other factors affect metabolism.

What's the biggest misconception people have about dieting?
That you can be any weight you want. The average weight loss is 5 to 10 percent of your body weight.

As you lose body fat, levels of certain hormones, including leptin, drop. The signaling pathway that tells you you're satisfied doesn't work when leptin levels are too low.
