How do calories relate to fat grams?

Answer by  janeiem (19)

Each gram of fat contains 9 calories. So eating a food with ten grams of fat multiplied by 9 calories per gram of fat, gives a total of 90 calories that come from fat. By comparison, protein and carbohydrates each contain 4 calories per gram.

Calories are the amount of energy your body gets from food. One gram of fat is equal to nine calories.
