Diet splurges lead to overeating.


Think of a night out with your friends: You get appetizers, margaritas, a full plate of cheesy enchiladas and by this point you’ve totally blown your diet, so what’s a little fried ice cream, right? Well, that logic has a name: the “what the hell” effect. Basically, when you cross a limit you’ve set for yourself, you lose control and just go all the way.

This study put that effect to the test. Researchers served participants a slice of pizza, and though the portions were equal, some slices were cut to appear larger or smaller than the others. Later, they asked participants to taste-test cookies, and allowed them to eat as many as they wanted.

Dieters (or anyone keeping tabs on their food intake) who believed they’d eaten a larger slice of pizza consumed more cookies than everyone else—50 percent more, in fact!

The effect on mood was even more interesting. People who tend to overeat felt worse if they ate the ‘large’ slice, while people who tend to restrict their diet felt better. Maybe they’re secretly happy to be allowed a little indulgence—we know we would be! 

Beauty connection

Stuck in a yo-yo diet cycle? When you restrict your eating too much and feel deprived of the delicious foods you really want, you’re more likely to swing to the other extreme. That’s why dieters often gain the weight back, rather than keeping it off.

To prevent this, keep up your healthy habits by starting small and adding one change at a time. Incorporate healthy fats, fiber and lean proteins so you fill up on nutritious meals, but indulge in delicious treats in moderation. You’ll be more satisfied (emotionally and physically), with a trimmer tummy to show for it.
