Treats are bound to tempt you when you’re dieting. Yet if you indulge every now and then, don’t beat yourself up. Women who felt guilty about eating treats were actually less successful at losing weight over a three-month period than women who felt happy while noshing, according to a new study in the journal Appetite. Researchers have several theories for why guilty feelings may inhibit weight loss—they may make you feel like you’ve lost control or are helpless or even make "forbidden" foods more desirable, resulting in increased cravings. So when you indulge in a treat (on occasion), enjoy it! Then get right back on track to eating well, no guilt necessary.
