American Psychological Association publication, "American Psychologist" published in the April to a new research shows that diet can make people lose weight temporarily, but the measure failed to reach the long-term weight loss goal.
This is the University of California, Los Angeles psychologist Trevor Seaman and other researchers on 31 case for diet analysis concluded. This finding confirms the view of many scientists: easy to maintain weight loss is difficult moment.
Rebound
23 Associated Press reported that 31 people participated in the survey Terre Seaman and others, experts in their diet after they began to launch a two to five years of follow-up study found that one-third of the one to two-thirds eventually returned to pre-diet weight. Only a handful of people did not rebound weight.
Trevor Seaman said: "We should not say diet, but that it should be clear that diet is only a temporary way."
Yale University obesity expert David Katz said, "if helpful for weight loss diet, then the streets will be full of skinny up."
Health experts say, ultimately the reason why weight loss diet is invalid, because it will make people feel tired, but people often can not withstand the temptation to relapse. Diet may also be in the weight reached a plateau after the collapse, there are people who, though lost weight, but did not completely change unhealthy lifestyles.

Consciousness
Roberta Perry Philadelphia suburbs in the United States has a public relations consulting firm, this 39-year-old career women once angry or frustrated, they will seek self-comfort from eating and drinking. In the past 20 years, she tried various weight loss methods, including participation in organized diet plans, diet pills, or even accept hypnosis and other psychological therapies.
These efforts have temporary work, but did not take long to lose weight slowly recovered. After several years of intermittent dieting, Perry finally realized that only changes in lifestyle, eat less and move, is the only effective way to lose weight. She now pay more attention to lower cholesterol, but not as relevant as a simple drop weight.
Result, about 1.7 meters tall when Perry from the fat of 147 kg to 113 kg, and has maintained for two years, no rebound. Although she still fat, but is no longer considered obese patient.
She said, "I want to be more healthy, I do not want to repeat the cycle of weight loss and then recovery."
It is not clear whether changes in an iterative weight can lead to health problems. However, studies have found increased blood pressure and cholesterol, and weight fluctuations, and cholecystitis may turn on.
The experts agreed that the surgery proved to be the only means of treating obesity. But the U.S. government advised people to try to lose weight using traditional methods, only at least 45 kilograms overweight people who can choose surgery.
Samuel Klein of Washington University obesity expert, said the success of weight loss not only to measure weight. If a person is more healthy, even if weight loss is only temporary, it should be regarded as successful.
He said, "Even if you lose weight after the weight has rebounded, but temporary weight loss not weight loss than good."
