What is the caloric value of 1 gram of fat?

The caloric value of 1 gram of fat is 9 calories. This is a fundamental concept in nutrition and exercise physiology, as it reflects how our bodies derive energy from macronutrients. Fats are the most energy-dense macronutrient, providing more than double the calories per gram compared to carbohydrates and proteins, both of which contain 4 calories per gram.

Understanding the caloric contribution of fat is essential for professionals in exercise physiology when developing dietary and exercise plans, as it emphasizes the role of fats in energy metabolism during both rest and physical activity. This knowledge helps in balancing macronutrient intake for optimal performance and health.
