Personally, I have a problem with the term "cheat meal". Simple choice of verbage makes a huge difference in how you perceive things. It sort of gives you a feeling of cheating on something, of something you should feel guilty about. To make matters worse, these cheat meals are then advertised as something that will "BOOST YOUR METABOLISM". I wish changing anything about your metabolism was that simple and easy. Anyhooo...I wanted to put a different perspective here. Mainly about our relationship with food. For those who go on a fat loss routine for months at stretch,they start to classify foods as good or bad. Good being the slow digesting, home cooked 'healthy' food and bad being anything they enjoy eating but is also termed as junk food. On one hand, this attitude does help in staying away from foods you're bound to overeat and keep making progress. But, on the other hand, the same people then also develop a fear of eating the foods they enjoy most. This creates a stressful situation when they go out for social gatherings or just eat out in general. In some cases, this also leads to developing eating disorders like bulimia, where the concerned person eats the "cheat meals" till they can't breathe anymore, feel guilty about it and then try to 'repair' the damage by either deliberately puking the food out or going on a starvation mode for the next few days. Here's my view: that one slice of pizza, or one meal of biryani, is not going to make you morbidly obese, or diabetic, or fuck up your thyroid or if you're a woman, bring back your PCOD/PCOS problems. It's just one meal. While you're out with your friends or family, then ENJOY that meal. Have a good time. Go back home and sleep peacefully. When you wake up in the morning and check your weight, you'll see your weight hadn't changed at all, or even if it did go up by a few pounds, your mirror will tell you the real story(nothing happened). One approach that has helped me set a healthy relationship with food for my clients is that, every once in a while, out of the blue, I *might* tell them to go out and have whatever they want. Of course, I ask them to weigh themselves in the morning of the "REWARD MEAL" and the morning after. There's always barely any difference. Allowing a fun meal like this every once in a while also helps prevent any development of fear of foods. This helps a great deal when they have to go on a vacation and they don't have to worry if they can eat something or not. They can enjoy their food just as much as others but strangely enough they don't even overeat these same foods . Win-win.
