If you burned one calorie per minute without eating breakfast, your metabolic rate would probably increase to two calories per minute by eating breakfast, Dr. Arad said. In an hour, you're probably burning 60 more calories. You may be thinking, "Well, burning more calories is great, isn't it?" But here's the thing: what you eat for breakfast will offset this extra caloric burn because we usually eat large breakfasts, he explained. "We're eating a lot of calories. So the increase in metabolism, in energy expenditure, it's certainly not what's going to help us lose the weight," he said. Ultimately, "the amount of energy your body is going to burn [by eating breakfast] is not going to be that significant."
