Fat Contains Twice the Calories of Carbs and Protein

Fat has more than twice the calories as the same amount of protein or carbohydrate. Protein and carbohydrate both have about 4 calories in each gram, but all fat-saturated, polyunsaturated or monounsaturated fat - has 9 calories in each gram. Thus, foods that are high in fat are high in calories. And all calories count. So, to maintain a desirable weight, it is important to eat no more calories than your body needs. (To find your desirable weight, see Body Mass Index)

Remember: To achieve or maintain a desirable weight, your caloric intake must not exceed the number of calories your body burns.
