Which nutrient is slower to provide energy but lasts a few hours longer?

• A. Fat
• B. Carbohydrates
• C. Protein
• D. Vitamins

Answer: (C)

Different nutrients fuel the body at different speeds. Fat is a slow-burning energy source: it takes longer to digest and mobilize, but once it’s used, it provides energy for many hours, especially during longer or lower-intensity activity. Carbohydrates supply energy quickly because they’re rapidly broken down into glucose, which is used right away for quick bursts of activity. Protein isn’t a primary energy source; it’s mainly for repairing and building tissues, with only a small amount of energy contributed during extended exercise. Vitamins don’t provide energy directly. So, the nutrient that is slower to provide energy but lasts a few hours longer is fat.
