Deprivation is the ruin of many a diet, so go ahead and occasionally have a small portion of dessert to satisfy your sweet tooth – it’ll make you more likely to stick to your diet. Just don’t overdo it: think of it as a treat, not a staple. Once or twice a week is reasonable. Choose your occasions wisely, plan ahead, and don’t skip a meal out of guilt. That way, you won’t feel so deprived that you turf the whole diet and stuff your face with truck loads of forbidden cake and ice cream.
