Combining physical activity with energy restriction leads to what effect on weight loss?

• A. No effect
• B. Increased weight loss
• C. Weight gain
• D. Unclear

Answer: (B)

Combining physical activity with energy restriction creates a larger overall energy deficit than either approach alone, which leads to greater weight loss. Exercise increases calories burned during activity and afterward (the afterburn effect), and resistance training helps preserve or build lean muscle mass. Keeping muscle supports a higher resting metabolic rate, making fat loss more sustainable over time. It also improves fat oxidation and insulin sensitivity, aiding the body's ability to shed fat. So, this combination typically results in more weight loss than restricting calories alone.
