How many calories do fats provide per gram?

Fats are a crucial macro-nutrient in our diet and provide the highest energy content of all the macronutrients. Each gram of fat delivers approximately 9 calories; this is significant compared to carbohydrates and proteins, which only provide about 4 calories per gram. Understanding the caloric density of fats is essential for nutritional planning and managing overall energy intake. This is why selecting the option that states fats provide 9 calories per gram is accurate and aligns with standard nutritional science. The higher energy yield from fats underscores their role as a dense source of energy, which can be particularly important in certain dietary contexts, such as low-carbohydrate diets. Recognizing this can help individuals make informed choices regarding energy sources in their meals.
