Macros for 150 lb Women (Maintenance, Moderately 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 moderately active TDEE (moderate exercise 3-5 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 | 113 lbs (75% of body weight) |
| Lean Mass (kg) | 51 kg |
| BMR (Katch-McArdle) | 1,472 cal/day |
| TDEE (BMR x 1.55) | 2,281 cal/day |
| Target Calories | 2,280 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 1.55 = moderate exercise 3-5 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 117g | 468 | 21% |
| Carbohydrates | 282g | 1128 | 49% |
| Fat | 76g | 684 | 30% |
| Total | - | 2,280 | 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
What are 282g of carbs used for in a maintenance diet?
The 282g of carbs provides 1128 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. At maintenance, 282g 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.
What foods hit 117g protein, 76g fat, and 282g carbs?
Protein sources for 117g: roughly 4 x 100g portions of chicken breast (31g protein each), or 20 eggs (6g each), combined with Greek yogurt or protein powder. Fat sources for 76g: about 5 tablespoons of olive oil or peanut butter. Carb sources for 282g: roughly 6 cups of cooked rice (45g each) or 10 cups of oats (27g each). A food tracking app is the most accurate way to hit these targets.
How does my activity level affect my 2280 calorie target?
Your Moderately Active activity level uses a multiplier of 1.55, giving a TDEE of 2281 calories. If you were sedentary (1.2x), your TDEE would be approximately 1766 calories. If you were very active (1.725x), it would be approximately 2539 calories. The activity multiplier is the single biggest variable in your calorie target. Getting it right matters more than small differences in the macro split.
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 1.55x estimate for moderately 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.
