How many calories are in 1 gram of fat?

In nutrition, it is well established that 1 gram of fat provides 9 calories (Kcal) of energy. This is an important factor for understanding macronutrient composition and the overall caloric content of foods. Fats are energy-dense compared to carbohydrates and proteins, which each provide 4 calories per gram. This distinction is crucial for nutrition coaches as they help clients balance their macronutrient intake according to their dietary needs and fitness goals. Understanding that fat provides more than double the caloric content of carbohydrates and proteins explains why managing fat intake is essential in weight management and dietary planning.
