Macros for 150 lb Men (Maintenance, Very Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 150 lb man on a maintenance diet. Calculated from estimated lean mass, Katch-McArdle BMR, and a very active TDEE (hard exercise 6-7 days per week).

Eating at TDEE with zero deficit or surplus. These macros maintain your 150 lb body weight while optimizing protein for muscle retention.
How These Macros Were Calculated
| Body Weight | 150 lbs |
|---|---|
| Estimated Lean Mass | 123 lbs (82% of body weight) |
| Lean Mass (kg) | 55.8 kg |
| BMR (Katch-McArdle) | 1,575 cal/day |
| TDEE (BMR x 1.725) | 2,717 cal/day |
| Target Calories | 2,719 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 1.725 = hard exercise 6-7 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 128g | 512 | 19% |
| Carbohydrates | 347g | 1388 | 51% |
| Fat | 91g | 819 | 30% |
| Total | - | 2,719 | 100% |
Protein is set at 2.3g per kg of lean body mass (123 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
Why is fat set at 91g for a maintenance diet?
Fat is set at 30% of total calories, which is 819 calories or 91g 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 128g of protein across meals?
Across 3 meals, each meal needs about 43g of protein. Across 5 meals or snacks, each needs about 26g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 43g per meal in 3 meals is within the optimal 30-40g range.
What are 347g of carbs used for in a maintenance diet?
The 347g of carbs provides 1388 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. At maintenance, 347g of carbs fuels daily activity at a sustainable level without gain or loss.
Should I recalculate my macros as I track weight?
At maintenance, recalculate your TDEE every 4-8 weeks if your weight shifts more than 5 lbs consistently. Lean mass changes affect calorie needs.
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 1.725x estimate for very 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 150 lbs.
