Harry wants to lose 50 pounds. Most experts would recommend that he should 

A) sharply increase his exercise.
B) sharply reduce his food intake.
C) decrease his food intake and increase his exercise, both in moderate ways.
D) sharply increase his exercise while simultaneously reducing his food intake dramatically.

It is generally recommended to approach weight loss with a combination of moderate reduction in calorie intake and moderate increase in physical activity. This approach is sustainable in the long term and reduces the risk of health complications. Sharp reductions in food intake or dramatic increases in exercise can lead to negative consequences such as nutrient deficiencies or injuries.
