Macros for 240 lb Men (Maintenance, Extra Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 240 lb man on a maintenance diet. Calculated from estimated lean mass, Katch-McArdle BMR, and a extra active TDEE (very hard exercise and physical job).

Eating at TDEE with zero deficit or surplus. These macros maintain your 240 lb body weight while optimizing protein for muscle retention.
How These Macros Were Calculated
| Body Weight | 240 lbs |
|---|---|
| Estimated Lean Mass | 197 lbs (82% of body weight) |
| Lean Mass (kg) | 89.3 kg |
| BMR (Katch-McArdle) | 2,299 cal/day |
| TDEE (BMR x 1.9) | 4,368 cal/day |
| Target Calories | 4,370 cal/day |
| Calorie Change | None (maintenance) |
| Expected Weekly Change | Stable weight |
BMR uses the Katch-McArdle formula (370 + 21.6 x lean mass kg), which accounts for lean mass and outperforms Harris-Benedict for accuracy across different body compositions. Lean mass estimated at 18% average body fat for men. Activity multiplier 1.9 = very hard exercise and physical job.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 205g | 820 | 19% |
| Carbohydrates | 559g | 2236 | 51% |
| Fat | 146g | 1314 | 30% |
| Total | - | 4,370 | 100% |
Protein is set at 2.3g per kg of lean body mass (197 lbs lean mass for this man). Fat targets 30% of target calories with a minimum safety floor applied if needed; carbs fill remaining calories, with a 50g minimum for brain function.

Frequently Asked Questions
How much weight will I change at 4370 calories?
At 4370 calories per day, your weight should stay stable within normal daily fluctuation (1-3 lbs of water weight). This is your estimated TDEE for extra active activity. If you consistently gain or lose weight at this intake, your actual TDEE differs from the estimate.
Why is fat set at 146g for a maintenance diet?
Fat is set at 30% of total calories, which is 1314 calories or 146g per day. Fat is essential for hormone production, fat-soluble vitamin absorption, and satiety. Keeping fat at 30% of calories maintains hormone function during maintenance. Dropping fat below 20% of total calories can impair testosterone, estrogen, and recovery.
How do I split 205g of protein across meals?
Across 3 meals, each meal needs about 68g of protein. Across 5 meals or snacks, each needs about 41g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 68g per meal in 3 meals is within the optimal 30-40g range.
What are 559g of carbs used for in a maintenance diet?
The 559g of carbs provides 2236 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. At maintenance, 559g of carbs fuels daily activity at a sustainable level without gain or loss.
When to Recalculate These Macros
Weight trending upward over 2 weeks
Reduce by 100-150 cal/day from carbs. Your actual TDEE is slightly below the 1.9x estimate for extra active activity.
Weight trending downward over 2 weeks
Add 100-150 cal/day from carbs or fat. You may be more active than the multiplier accounts for, or your metabolism has adapted upward.
Activity level has changed significantly
Switch to the matching activity level using the selector above. The difference between sedentary and moderately active can be 300-500 cal/day at 240 lbs.
