a gram of carbs contains how many calories
Nutrition labels list the volume of carbohydrates, fat, and protein in a food, rather than the calories derived from these nutrients. In order to ascertain how many calories come from carbohydrates, you need to know the calories per gram of carbs. The number of calories in a food is a measure of how much potential energy that food possesses. A gram of carbohydrates has 4 calories, a gram of protein has 4 calories, and a gram of fat has 9 calories. Foods are a compilation of these three building blocks. So if you know how many carbohydrates, fats and proteins are in any given food, you know how many calories, or how much energy, that food contains. Each food contains a different amount of energy. All calories supply your body with the same amount of energy, regardless of the type of food from which they come. For example, fat calories have the same amount of energy as protein calories.
