Are calories as simple as energy in, energy out? if you're trying to drop a few pounds — or just want to maintain your weight as it is — you may think calorie counting is all you have to do. In reality, it's a little more complicated than that.
NBC's medical correspondent Dr. Natalie Azar busts three common calorie myths.

It’s not only how much you eat, but what you eat. Try to balance your daily consumption between carbohydrates (45-65 percent of daily calories) with fat (20-35 percent) and protein (10-35 percent).

3. Some foods burn more calories than they contain.
Not true! Watch the video to learn how many calories are burned through digestion each day.
