How many calories are in 1 gram of fat?

• A. 4 calories
• B. 7 calories
• C. 9 calories
• D. 5 calories

Answer: (C)

1 gram of fat provides 9 calories of energy. This is based on the biochemical understanding of macronutrients, where fats are the most calorie-dense of the three major macronutrient groups, which also include carbohydrates and proteins. Fats, as a macronutrient, play a crucial role in energy storage, absorption of fat-soluble vitamins, and as precursors for hormones. The high caloric value of fat is significant in dietary planning and understanding energy balance, which is essential for weight management and overall health. In contrast, carbohydrates typically provide about 4 calories per gram, and proteins also yield approximately 4 calories per gram. Understanding these values helps in nutrient calculations for both dietary recommendations and meal planning. The specific caloric value of fat is critical when considering macronutrient ratios in various diets.
