What is the caloric yield of 1 gram of fat?

• A. 7 calories
• B. 8 calories
• C. 9 calories
• D. 10 calories

Answer: (C)

The caloric yield of fat is established at 9 calories per gram. This figure is derived from the caloric content of macronutrients, which indicates the energy provided by each type. Fats are known to be the most energy-dense macronutrient, delivering a substantial amount of energy compared to carbohydrates and proteins, which yield 4 calories per gram. Understanding the caloric yield is crucial in nutritional science and weight management, as it highlights how dietary fats contribute to overall caloric intake. When incorporating fats into a diet, knowing that each gram contributes 9 calories helps in accurately calculating daily caloric needs and managing weight effectively.
