or anxiety.

The results suggest that beginning a diet with a fast or near-fast may alter brain chemistry in a way that adversely affects mood and motivation, undermining the person's weight-loss efforts.

"The obese mice simply didn't move as much as the other mice. Not only was there reduced locomotion generally, they didn't burrow in the way that mice normally do, and that's associated with depression and anxiety," he said.

Beginning a weight-loss program in a depressed frame of mind and with decreased motivation doesn't bode well for the diet's success, he noted.
