What is the calorie content of 1 gram of fat?

4 calories
9 calories
7 calories
6 calories

The correct answer is: 9 calories

One gram of fat contains 9 calories, which is the correct answer. This higher calorie content compared to carbohydrates and proteins is significant for understanding dietary energy. Carbohydrates and proteins each provide about 4 calories per gram, while fat is a denser source of energy. The reason fat is so energy-dense is due to its chemical structure, which allows for a greater number of bonds that store energy. This information is crucial for personal trainers when helping clients with nutrition and weight management, as it highlights the importance of fat in the diet while also emphasizing moderation due to its high caloric value. Understanding the energy content of macronutrients is essential for designing effective nutrition plans.
