We have been hearing since long that reducing intake of some calories a day can help us reduce some weight. Moreover, even doctors have been advising people willing to lose weight in order to drop 500 calories a day so that they reduce their weight approx 1lb a week.

But Mr. Kevin Hill of the National Institutes of Health in the United States says, "This is wrong. It does not happen". The professional further marked that change in metabolism do not reduces weight rather the body starts adjusting itself with the reducing energy intake i. e. calories eaten by slowing its energy output (calories expended).

Moreover, the study has also highlighted that heavier people lose weight faster as compared to lighter people on the same diet, but it has also been marked in the study that heavier people take longer to reduce till the targeted weight than their thin counterparts.

Next fact, which was showcased from the study, said that maximum people on diet start noticing maximum weight loss only after six to eight months.

According to the researchers, it is just a natural plateauing effect which is the result of slowed metabolism. But many evidences have proved the fact that sticking on diet for more than six months is not done by many people as they start finding it hard to do same, and thus they stop losing the weight and the desired target is not achieved.
