What is a protective factor against overweight/obesity?

• A. Skippings meals
• B. High-fat diet
• C. Sedentary behavior
• D. Regular exercise

Answer: (D)

Regular physical activity helps prevent overweight and obesity by tipping the energy balance toward expenditure and by improving the body’s metabolic health. When you move more, you burn more calories, which makes it easier to maintain or lose weight over time. Exercise also supports maintaining lean muscle mass, which helps keep the resting metabolic rate higher and improves how the body processes fats and sugars. Beyond calories in and out, regular activity can regulate appetite signals and reduce fat accumulation, making it a protective factor for healthy weight.

Skipping meals can disrupt energy balance and lead to late-day overeating or nutrient gaps, without reliably preventing weight gain. A high-fat diet increases energy density and, if eaten in excess, contributes to weight gain. Sedentary behavior lowers energy expenditure, increasing the risk of overweight and obesity. Regular exercise uniquely supports weight management by increasing energy expenditure and promoting healthier metabolic function, which is why it is the best protective factor here.
