Detailed explanation-1: -How many calories are in one gram of fat, carbohydrate, or protein? Carbohydrates provide 4 calories per gram, protein provides 4 calories per gram, and fat provides 9 calories per gram. This information is also included at the end of the Nutrition Facts label on food packages.
Detailed explanation-2: -One kilogram of fat is equivalent to 9000 calories of energy; One kilogram of body fat is 80% of 9000, which is 7, 200 calories; and, Converting 3, 500 calories per pound to kilograms gives 7, 700 calories per 1kg.
Detailed explanation-3: -How many fat grams is that? There are 9 calories in a gram of fat, so divide the number of calories by 9. Divide 400 calories by 9 to get 44 grams. Then divide 700 calories by 9 to get 78 grams.
