To maintain 200 pounds, most people need between 2,400 and 3,200 calories per day, depending on age, sex, height, and how physically active they are. That’s a wide range, and where you fall within it matters. The single biggest factor isn’t your workout routine. It’s how much you move throughout the rest of your day.
How Maintenance Calories Are Calculated
Your body burns calories in three main ways. The largest share, roughly 60 to 70 percent, goes to keeping you alive: breathing, circulating blood, maintaining body temperature, and running your organs. This is your basal metabolic rate, or BMR. On top of that, about 10 percent of the calories you eat get burned just digesting and processing food. The rest comes from physical activity, both structured exercise and all the smaller movements you make throughout the day like walking, fidgeting, standing, and doing chores.
The most widely used formula for estimating BMR is the Mifflin-St Jeor equation, which factors in your weight, height, age, and sex. Once you have that number, you multiply it by an activity factor to get your total daily energy expenditure, the number of calories you’d need to eat to stay at your current weight.
Calorie Estimates at 200 Pounds by Activity Level
Here’s what maintenance calories look like for a 200-pound person at different activity levels, using standard activity multipliers. These assume an average height (5’10” for men, 5’5″ for women) and age of 35.
- Sedentary (desk job, little or no exercise): roughly 2,400 calories for men, 2,100 for women. The multiplier here is 1.2, reflecting minimal movement beyond daily basics.
- Lightly active (exercise 1 to 3 days per week): roughly 2,750 for men, 2,400 for women, using a multiplier of 1.375.
- Moderately active (exercise 3 to 5 days per week): roughly 3,100 for men, 2,650 for women, with a 1.55 multiplier.
- Very active (physical job or intense exercise 6+ days per week): roughly 3,500 for men, 3,050 for women, at a 1.725 multiplier.
These are estimates, not exact prescriptions. Your actual number could be 200 to 300 calories higher or lower depending on your specific height, age, and body composition. But they give you a solid starting point.
Why Activity Level Matters More Than You Think
Most people focus on gym sessions when they think about calories burned through activity. But the movement you do outside of exercise, things like walking to the store, cooking dinner, pacing during phone calls, or standing at your desk, often accounts for far more total energy. Differences in this kind of daily movement can account for up to 2,000 calories per day between two people of the same size. That’s an enormous gap, and it explains why two 200-pound people with similar workout habits can have very different calorie needs.
Simply increasing the amount of time you spend standing and walking by about two and a half hours per day can raise your calorie burn by roughly 350 calories. That’s the equivalent of a moderate meal, earned without setting foot in a gym. If you have a desk job and drive everywhere, your maintenance calories will sit at the lower end of the range. If you’re on your feet most of the day, they’ll be significantly higher.
How Age Affects Your Number
The conventional wisdom is that metabolism slows steadily after your twenties. That turns out to be mostly wrong. A large-scale study published in Science found that both total energy expenditure and basal metabolic rate remain remarkably stable from age 20 all the way to about 60, regardless of sex. The slow creep of weight gain that many people experience in their thirties and forties is more likely driven by changes in activity and eating habits than by a declining metabolism.
After 60, things do shift. Metabolic rate begins to decline by about 0.7 percent per year, and by age 90, adjusted energy expenditure is roughly 26 percent lower than in middle-aged adults. So if you’re 40 and 200 pounds, your maintenance calories are essentially the same as they were at 25. If you’re 70, you’ll need to subtract a meaningful amount from the estimates above.
Body Composition Changes the Equation
Two people can both weigh 200 pounds and have very different calorie needs based on how much of that weight is muscle versus fat. Muscle tissue burns more calories at rest than fat tissue does. A 200-pound person with a higher proportion of lean mass will have a higher BMR, sometimes by several hundred calories, compared to someone at the same weight carrying more body fat.
This is one reason calorie calculators are estimates rather than precise measurements. They can’t account for your individual ratio of muscle to fat. If you strength train regularly and carry above-average muscle mass, your real maintenance calories are likely higher than what a formula predicts. If you’ve been relatively inactive and carry more fat at 200 pounds, they may be slightly lower.
How to Find Your Actual Number
Calculators give you a starting point. Finding your true maintenance intake takes a couple of weeks of tracking. Start by eating the number of calories a calculator suggests for your activity level. Weigh yourself at the same time each morning for two weeks, and track the trend rather than any single day’s reading. Water weight can swing your scale by two to four pounds from one morning to the next, so daily fluctuations don’t mean much.
If your average weight stays stable over those two weeks, you’ve found your maintenance calories. If you’re gaining, reduce by 200 to 300 calories and reassess. If you’re losing, add 200 to 300. This trial-and-error approach takes patience, but it accounts for all the individual variables that no formula can capture, including your genetics, your gut bacteria, your stress levels, and the hundreds of small movements you make without thinking about them.
Protein’s Role in Staying at 200 Pounds
If your goal is to maintain 200 pounds while keeping your body composition healthy, protein matters independently of total calories. The baseline recommendation is 0.36 grams of protein per pound of body weight, which works out to about 72 grams per day for a 200-pound person. But that minimum is set to prevent deficiency, not to optimize muscle retention. Many nutrition researchers suggest higher intakes, particularly for people who exercise, to preserve muscle mass and support recovery. A common target for active individuals is 0.7 to 1.0 grams per pound, or 140 to 200 grams daily at your weight.
Protein also has a higher thermic effect than carbohydrates or fat, meaning your body burns more calories digesting it. This won’t dramatically change your maintenance number, but over time, a higher-protein diet can make it slightly easier to maintain your weight without consciously eating less.
