Tag: 9 kcal per gram

A single gram of fat contains more than twice the energy of a gram of carbohydrate or protein. This high energy density means that lipids, or fats, are the molecules that can be broken down to yield approximately 9 kilocalories per gram.

Every single gram of fat provides the body with approximately 9 calories (also known as kilocalories), making it the most energy-dense macronutrient. This is more than double the energy provided by carbohydrates or proteins, a fact that explains why the body uses it as its most efficient form of energy storage.
