"This is the first time the number has been calculated.We did not know how big this number it was before the study, "says researcher Kevin Hall, PhD of the National Institute of Health in Bethesda, in the United States, who seeks to understand how the body responds to weight loss.
The researcher discovered the body of the participants was struggling with weight loss, leading them to eat more to offset the deficit. If a person who normally eats about 2,700 calories a day loses about 4kg, the body will try to make him eat about 400 calories more than they were before - a total of 3,100 calories per day. has some limitations and the next step is to do research with people who have a healthy lifestyle. In addition, it is still unclear how these changes in appetite apply to different amounts of weight loss. Researchers believe this research should change how physicians will treat patients in the weight loss phase. "This is a landmark study.It gives us some very useful information that will really help develop new guidelines to avoid weight recovery," says Ken Fujioka, MD, director of the metabolic research center at Scripps Clinic in California, The study also found that 80% of people who lost up to 10% of their body weight regained weight gradually or gained more weight than expected.
For decades, researchers have been working to understand why so difficult to maintain weight loss. A study of participants in the American reality show "The Biggest Loser" showed how, after 6 years of the program, everyone had regained their weight. The explanation is linked to metabolism, which determines how many calories a person burns when he or she rests.
When the program started, participants, even overweight, had normal metabolisms for their weight, that is, they burned the normal number of calories. calories for people with obesity. But at the end of the reality, the metabolism of the participants had slowed down radically and they were not burning enough calories to keep the body slim.
Researchers still do not understand how food intake is affected after weight loss, this because people can not control how much they eat daily. In addition, they find it difficult to measure the appetite with the use of medications, since they decrease appetite, thus interfering with the results.
