This Diet Worked Before - Why Doesn't it Work Now?

Have you ever heard of hibernation mode? When a bear stores up fat for the winter, his body goes into a hibernation mode. It stops burning that fat at the normal rate. The bear's metabolism says,"Hey, remember the last time when the food stopped coming for a couple months? It looks like that's going to happen again. If there is going to be a food shortage for the next couple months, I won't burn the calories." The bear has a built-in system for not losing weight based on the food supply called the hibernation mode. So do you.
