Question: how many calories should a 120 lb woman burn?
Answer: (Thus, a 120-pound moderately active person needs to eat about 1,680 calories--1,200 plus about 480 calories for activity--to maintain his or her weight, while a sedentary 150-pound person would need to consume about 1,800 calories daily--1,500 calories plus 300--to keep the bathroom scale steady.)
