Macros for 150 lb Women (Maintenance, Extra Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 150 lb woman 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 150 lb body weight while optimizing protein for muscle retention.
How These Macros Were Calculated
| Body Weight | 150 lbs |
|---|---|
| Estimated Lean Mass | 113 lbs (75% of body weight) |
| Lean Mass (kg) | 51 kg |
| BMR (Katch-McArdle) | 1,472 cal/day |
| TDEE (BMR x 1.9) | 2,796 cal/day |
| Target Calories | 2,797 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 25% average body fat for women. Activity multiplier 1.9 = very hard exercise and physical job.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 117g | 468 | 17% |
| Carbohydrates | 373g | 1492 | 53% |
| Fat | 93g | 837 | 30% |
| Total | - | 2,797 | 100% |
Protein is set at 2.3g per kg of lean body mass (113 lbs lean mass for this woman). 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 93g for a maintenance diet?
Fat is set at 30% of total calories, which is 837 calories or 93g 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 117g of protein across meals?
Across 3 meals, each meal needs about 39g of protein. Across 5 meals or snacks, each needs about 23g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 39g per meal in 3 meals is within the optimal 30-40g range.
What are 373g of carbs used for in a maintenance diet?
The 373g of carbs provides 1492 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. At maintenance, 373g 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 1.9x 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 150 lbs.
