"Genes Take Charge, and Diets Fall by the Wayside"
Sigh! ^_^ http://www.nytimes.com/2007/05/08/he...1&ei =5087%0A EXCERPTS Every time the result was the same. The weight, so painstakingly lost, came right back. But since this was a research study, the investigators were also measuring metabolic changes, psychiatric conditions, body temperature and pulse. And that led them to a surprising conclusion: fat people who lost large amounts of weight might look like someone who was never fat, but they were very different. In fact, by every metabolic measurement, they seemed like people who were starving. .... The Rockefeller researchers explained their observations in one of their papers: "It is entirely possible that weight reduction, instead of resulting in a normal state for obese patients, results in an abnormal state resembling that of starved nonobese individuals." Eventually, more than 50 people lived at the hospital and lost weight, and every one had physical and psychological signs of starvation. There were a very few who did not get fat again, but they made staying thin their life's work, becoming Weight Watchers lecturers, for example, and, always, counting calories and maintaining themselves in a permanent state of starvation. .... The implications were clear. There is a reason that fat people cannot stay thin after they diet and that thin people cannot stay fat when they force themselves to gain weight. The body's metabolism speeds up or slows down to keep weight within a narrow range. Gain weight and the metabolism can as much as double; lose weight and it can slow to half its original speed. .... The message never really got out to the nation's dieters, but a few research scientists were intrigued and asked the next question about body weight: Is body weight inherited, or is obesity more of an inadvertent, almost unconscious response to a society where food is cheap, abundant and tempting? An extra 100 calories a day will pile on 10 pounds in a year, public health messages often say. In five years, that is 50 pounds. .... Dr. Stunkard ended up with 540 adults whose average age was 40. They had been adopted when they were very young - 55 percent had been adopted in the first month of life and 90 percent were adopted in the first year of life. His conclusions, published in The New England Journal of Medicine in 1986, were unequivocal. The adoptees were as fat as their biological parents, and how fat they were had no relation to how fat their adoptive parents were. |

"Genes Take Charge, and Diets Fall by the Wayside"
I have serious doubts about the "starvation" part, but the characterization
of the type of person who is able to maintain a weightloss seems right. 2% win Some say 5%, but that is for a shorter period of study time. Although "they" say yo-yo dieting is bad for you. IMHO the alternative may be a steady gain into the range of morbid obesity. Yo-yo diets become the lesser evil. "Prisoner at War" wrote in message ups.com...
