– 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 a way of measuring how much energy is in food. Carbohydrates, fats and proteins all have calories in them. Just that eating nothing but fats to get the calories your body needs is rare. Most people get the majority of their energy, from the calories found in carbohydrates in rice, pasta, potatoes, bread and sugar.
