Drs. Oz Roizen sig

Around 55% of the 170 million American adults who are overweight or obese say they want to lose weight. But it’s a challenge — many folks try but fail to shed significant weight, and most of those who succeed regain much or all of it within three to five years.

Why is it so tough to reach your goal? One obstacle you might not have considered: your attitude toward yourself when you overeat, eat foods you’ve declared you will avoid, or eat at a time you said you wouldn’t.
