How many calories does fat contain per gram compared to carbohydrates and protein?

Fat contains nine calories per gram, which makes it the most calorie-dense macronutrient compared to carbohydrates and protein. Carbohydrates and protein each provide approximately four calories per gram. This distinct difference in caloric density is important for understanding weight management and energy balance.

When formulating diets or meal plans for weight control, recognizing that fats offer more than double the calories of an equivalent amount of carbohydrates or protein can help individuals make informed choices about their food intake. This knowledge is vital for anyone looking to manage their weight effectively, as higher calorie content can influence overall energy consumption and nutritional balance in one's diet.
