You see them counted on food labels and now on restaurant menus. But do you know what calories are?
Anya Guy, a Mayo Clinic dietitian, says calories are units of energy. And even though they are all technically the same, the effect they have on your body can differ depending on what kinds of food you eat.
"A calorie is a unit of energy," Guy says. "It is calculated for various types of foods, more so in the categories of calories from carbohydrates, protein and fat."
