A 200-lb. adult's calorie needs can vary tremendously depending on his medical condition, level of activity, height and gender. Consult a physician or dietitian for expert advice on managing your personal calorie needs.
According to the National Institutes of Health, a weight of 200 lbs. is healthy and acceptable for adults who are over 6 feet, 4 inches in total height. To maintain this weight and stay healthy, engage in regular exercise and eat a balanced diet.
The NIH reports that several factors can increase or decrease your calorie needs. People who are female and sedentary have much lower calorie requirements than active males. Those who are pregnant, nursing or coping with chronic illness may have higher than average calorie requirements.
For Sedentary People
According to MayoClinic.com, a sedentary adult needs 2,150 to 2,550 calories each day to maintain a weight of 200 lbs.
If you engage in light to moderate exercise a few times per week, you will need to consume 2,350 to 3,100 calories each day to maintain a 200-lb. weight.
For Active People
Extremely athletic people have very high calorie needs. MayoClinic.com recommends consuming a minimum of 3,000 calories per day to maintain a weight of 200 lbs. if you exercise vigorously every day. Some active people may need as many as 3,800 calories per day to replace dietary energy burned during exercise.
