How many calories are equivalent to one pound of body weight?

2500 calories
3000 calories
3500 calories
4000 calories

The correct answer is: 3500 calories

One pound of body weight is generally considered to be equivalent to 3,500 calories. This value is widely used in weight management and fitness contexts to estimate caloric deficits and surpluses needed for weight loss or gain. The 3,500-calorie rule stems from research that demonstrated individuals typically need to expend approximately this amount more than they consume to lose a pound of fat. This estimate serves as a benchmark for personal trainers and clients looking to create weight loss plans, making it an important concept in the field of exercise science and nutrition. While actual weight loss can vary based on several factors, including metabolism, body composition, and individual differences, the 3,500-calorie figure remains a useful guideline for understanding the caloric aspect of weight management.
