Macros for 180 lb Women (Maintenance, Very Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 180 lb woman 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 180 lb body weight while optimizing protein for muscle retention.
How These Macros Were Calculated
| Body Weight | 180 lbs |
|---|---|
| Estimated Lean Mass | 135 lbs (75% of body weight) |
| Lean Mass (kg) | 61.2 kg |
| BMR (Katch-McArdle) | 1,692 cal/day |
| TDEE (BMR x 1.725) | 2,919 cal/day |
| Target Calories | 2,921 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 1.725 = hard exercise 6-7 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 141g | 564 | 19% |
| Carbohydrates | 371g | 1484 | 51% |
| Fat | 97g | 873 | 30% |
| Total | - | 2,921 | 100% |
Protein is set at 2.3g per kg of lean body mass (135 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
How do I split 141g of protein across meals?
Across 3 meals, each meal needs about 47g of protein. Across 5 meals or snacks, each needs about 28g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 47g per meal in 3 meals is within the optimal 30-40g range.
What are 371g of carbs used for in a maintenance diet?
The 371g of carbs provides 1484 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. At maintenance, 371g 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 141g protein, 97g fat, and 371g carbs?
Protein sources for 141g: roughly 5 x 100g portions of chicken breast (31g protein each), or 24 eggs (6g each), combined with Greek yogurt or protein powder. Fat sources for 97g: about 7 tablespoons of olive oil or peanut butter. Carb sources for 371g: roughly 8 cups of cooked rice (45g each) or 14 cups of oats (27g each). A food tracking app is the most accurate way to hit these targets.
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 180 lbs.
