It is a common notion that people losing weight through dieting and tend to gain back the extra pounds they had lost by eating food items that are high in fat. A research has suggested that the probable reason why people tend eat more after dieting is because there brain tends to react differently to stress and when dieting they eat more.

The research involved mice being put on a diet, following which, it was found that mice, which had gone through dieting, tended to eat food items that were high in fat content. Whereas, in comparison the mice, which did not go through a diet ate food less in fat content.

Experts involved in the study have said that a possible reason behind the changing behavior to eating patterns under stress could be because of the alterations that happen in the genes of mice. Tracy Bale from the University of Pennsylvania and one of the authors of the study said that if a human goes through a famine or starvation, its brain usually protects it from losing out on calories again by the encouraging the promotion of high fat food consumption.

In earlier times because of the less availability of fat foods, humans did not gain much weight in such situations, but with more fat foods being available these days such situations lead to drastic weight gain.

Dr. Jeffrey Zignman from the University of Texas, while commenting on the study said that the study showed the hurdles that people these days face in order to maintain their weight.
