I posted this under another forum and then saw this one....
Even more of a reason to work hard at life-long Atkins and to stay in touch for support in the ADBB, here is an article in the Wall St. Journal today that says:
Can't Keep the Weight Off?
Maybe Leptin Is the Culprit
"So, you ate less and exercised more and lost weight. But now the pounds are piling back on. You're hungrier than ever, and you can't seem to resist food. Once again, it's all your fault, right?
Wrong. Blame evolution, and the fact that for the vast majority of human history, famine was a bigger threat than flab. Even your seeming lack of will power is part of a complex biological system that drives humans who have lost weight to regain it, according to new brain-scan research by scientists at Columbia University Medical Center."
..."Loosely put, after you've lost weight, you have more of an emotional response to food and less ability to control that response," says Michael Rosenbaum, lead author of the study in this month's Journal of Clinical Investigation. The key driver of this system is leptin, a hormone secreted by fat cells. When humans (and rodents) lose 10% or more of their body weight, leptin falls rapidly and sets off a cascade of physiological changes that act to put weight back on. Skeletal muscles work more efficiently, thyroid and other hormones are reduced -- all so the body burns 15% to 20% fewer calories, enough to put back 25 pounds or more a year.
This mechanism kicks in whether people are obese or relatively lean before losing weight -- and researchers believe the effect can last for years."
...How do some people manage to overcome the leptin effect and keep weight off? Generally by watching their food intake very carefully and continuing to increase their physical activity. "Anybody who has lost weight and kept it off will tell you that they have to keep battling," says Dr. Rosenbaum. "They have essentially reinvented themselves, and they are worthy of the utmost admiration and respect."

OK I'll fess up: the fighting emoticons were my addition, don't know why the editors at the WSJ did not just insert them right there....
