This is not an excuse to eat junk food every day. The truth is that your body needs a certain amount of calories every day. Providing fewer than that puts it in a stressful situation – because the body is very smart – to which it feels it has to respond by storing fat (to conserve energy) because it has learned it won’t get enough during the day. So don’t cut your calories intake. Rather, get them from complex carbs and proteins. Your body will thank you by giving you what you want – losing weight and staying healthy and fit.
