– if carbohydrates are the body’s energy source, what exactly are calories?

Question

I keep hearing that carbs are the body’s fuel, but fats contain more calories per gram. Surely that means fat is the body’s primary source of fuel?

Answer 1

Calories are an amount of energy in food. 4 calories per gram of protein, or carbs and 9 calories per gram of fat. Your body can turn carbs into energy faster than it can turn fat into energy so it prefers to use carbs. You can condition your body to use primarily fat for energy which is what the keto does does.
