Rebel Wilson's Controversial Diet Claim: 600 Calories a Day is Enough.

Rebel Wilson revealed that people only need about 600 calories a day, but clarified that it's usually done as a detox and not intended as a daily routine. She also dispelled the rumor that she's carb-free after her dramatic weight loss and explained that she eats carbs in small portions. Wilson attributed most people's weight gain to stress and turning to food, but claimed that "you just don't need all that food." Despite her regimented diet, she indulges in ice cream as her "cheat food" every now and then.
