There's no satisfaction like a few bites of greasy pizza when you've been sticking to your healthy diet for the past month—until those few bites lead to a few slices, and that one bad meal leads to an entire day of bad eating. Cheat meals, it is a reward for eating clean, staying active through the week or month. And you can get back to your diet plan with all new vigor and enthusiasm.
The simple logic behind these occasional meals is that it makes you very happy. We are all human beings at the end of the day, the positive effect is mostly psychological than physiological. One is that we have eaten clean and healthy for the whole week and want to take it easy on one last day of the week. Second is when we are on a specific diet plan for a week and take a day off to satiate our taste buds with our favorite foods.
You cannot be having your cheat meal whenever you like or how much you want. It is best to plan your cheat meal prior; suppose you plan it towards the end of the week, it feels like a reward for a job well done but not every week. Dieting is not a punishment, and works only when you embrace it wholeheartedly. Cheat meals can work very well for those who take this meal as a way of giving in to their cravings, only to get back to their promise of healthy eating with renewed zest.
