On average, how many calories does one gram of fat provide?

One gram of fat provides approximately 9 calories. This value is significant because it highlights the energy density of fats compared to other macronutrients. For instance, carbohydrates and proteins each provide about 4 calories per gram. The higher calorie content of fat means that fats are more energy-dense, making them an important source of energy in a balanced diet. This distinction is essential for understanding dietary needs and making informed choices about the types of foods consumed, especially for those in culinary and nutrition fields.
