Which nutrients are used primarily to provide energy?

• A. Carbs, Proteins, and Fats
• B. Vitamins and Minerals
• C. Fiber and Water
• D. Minerals Only

Answer: (A)

Energy in the body comes from the calories provided by macronutrients: carbohydrates, fats, and proteins. These are the nutrients the body can metabolize for fuel. Carbohydrates supply readily available energy through glucose for quick activity and brain function. Fats provide the most energy per gram, supporting longer, more sustained activity. Proteins can be used for energy if needed, but their primary role is to build and repair tissues and support metabolic functions; they are not relied on for daily energy as much as carbohydrates and fats. Vitamins and minerals don’t provide calories, so they don’t directly supply energy. Fiber and water also don’t offer usable energy in the body’s normal energy metabolism.
