Calorie needs for men may range based on several factors. The most recent Dietary Guidelines for Americans estimates that men between the ages of 19–30 should consume 2,400–3,000 calories per day to maintain their weight.
Energy needs decrease as you get older. In fact, men between the ages of 31–59 need about 2,200–3,000 calories per day to maintain their weight, while men over 60 generally require 2,000–2,600 calories.
Men who are very active or have certain health conditions may require more calories. The number you need within these ranges also varies based on your height and weight.
