Which nutrient provides insulation and temperature regulation?

Which nutrient provides insulation and temperature regulation?

• A. Carbohydrates
• B. Proteins
• C. Fats
• D. Vitamins

Answer: (C)

Fats provide insulation and help regulate body temperature because stored fat, especially in a subcutaneous layer beneath the skin, acts as an insulating barrier that slows heat loss to the environment. This adipose tissue helps keep the body's core warmer in cold conditions. Fats also offer a dense energy source for metabolism, but their insulating role is what directly supports temperature regulation. Carbohydrates supply quick energy but don’t form insulating layers; proteins contribute to structure and function rather than insulation; vitamins are micronutrients that support metabolism but do not provide insulation.
