Researchers have unveiled the mystery behind why people put on weight after shedding some weight, post a diet program, in a recent study.

Researchers believe this could be a key reason why most people who lose weight on a diet eventually put weight back on, reports Science Daily.
In laboratory studies, a doctoral student from the University of Adelaide, Stephen Kentish investigated the impact of a high-fat diet on the gut's ability to signal fullness, and whether those changes revert back to normal by losing weight.
The results that were published in International Journal of Obesity show the nerves in the stomach that signal fullness to the brain appear to be desensitized after long-term consumption of a high-fat diet.
