How many calories does 1 gram of lipids (fat) provide?

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

Answer: (B)

1 gram of lipids, commonly referred to as fats, provides 9 calories. This amount is significant when considering dietary fats and their role in energy intake. Fats are more energy-dense than carbohydrates or proteins, which both provide only 4 calories per gram. The high calorie content allows fats to serve as a vital energy source for the body and is essential for various functions, including hormone production, absorption of fat-soluble vitamins, and providing insulation and protection for organs. Understanding the caloric value of macronutrients is crucial for anyone studying nutrition, as it aids in meal planning and managing dietary goals effectively.
