There Is A Scientific Reason Why Dieting Is Not Helping You  Lose Weight


These new dieting fads are of no use. Rather they can do a lot of harm to your body. You may be at a loss, as human bodies tend to compensate by sparing energy, limiting the number of calories that we burn and hence affect our weight loss regimen, researchers say.

According to the study, a group of neurons -- 'agouti-related neuropeptide' (AGRP) -- in a brain region hypothalamus contributes to the caloric thermostat that regulates our weight, regulating how many calories we burn. When activated, these neurons make us hungry and drive us to eat, but when there is no food available, they tend to compensate for the reduction in calories.

"Our findings suggest that AGRP in the brain coordinate appetite and energy expenditure, and can turn a switch on and off to burn or spare calories depending on what's available in the environment," said Clemence Blouet from the University of Cambridge in Britain.

"When we eat less, our body compensates and burns fewer calories, which makes losing weight harder," Blouet added.
However, as soon as food becomes available and we start eating, the action of the AGRP neurons is interrupted and our energy expenditure goes back up again to normal levels.
In the study, published in the journal eLife, the researchers identified a new mechanism through which the body adapts to low caloric intake and limits weight loss in mice.

Using a genetic trick to switch the AGRP neurons 'on' and 'off,' they rapidly and reversibly manipulated the neurons' activity in mice, a finding that could help in the design of new or improved therapies in future to help reduce overeating and obesity, the researchers said.

What scientists are uncovering should bring fresh hope to the 155 million Americans who are overweight, according to the U.S. Centers for Disease Control and Prevention. Leading researchers finally agree, for instance, that exercise, while critical to good health, is not an especially reliable way to keep off body fat over the long term. And the overly simplistic arithmetic of calories in vs. calories out has given way to the more nuanced understanding that it's the composition of a person's diet--rather than how much of it they can burn off working out--that sustains weight loss.

They also know that the best diet for you is very likely not the best diet for your next-door neighbor. Individual responses to different diets--from low fat and vegan to low carb and paleo--vary enormously. "Some people on a diet program lose 60 lb. and keep it off for two years, and other people follow the same program religiously, and they gain 5 lb.," says Frank Sacks, a leading weight-loss researcher and professor of cardiovascular disease prevention at the Harvard T.H. Chan School of Public Health. "If we can figure out why, the potential to help people will be huge."
