Macros for 180 lb Women (Maintenance, Sedentary)
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 sedentary TDEE (desk job, little or no exercise).

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 1.2) | 2,030 cal/day |
| Target Calories | 2,029 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 1.2 = desk job, little or no exercise.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 141g | 564 | 28% |
| Carbohydrates | 202g | 808 | 40% |
| Fat | 73g | 657 | 32% |
| Total | - | 2,029 | 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
Why is protein 141g for maintenance at 180 lbs?
Protein for maintenance is set at 2.3g per kg of lean body mass. A 180 lb woman with 135 lbs of lean mass needs 141g of protein per day. At maintenance, 2.3g per kg of lean mass supports daily muscle repair and satiety.
How much weight will I change at 2029 calories?
At 2029 calories per day, your weight should stay stable within normal daily fluctuation (1-3 lbs of water weight). This is your estimated TDEE for sedentary activity. If you consistently gain or lose weight at this intake, your actual TDEE differs from the estimate.
Why is fat set at 73g for a maintenance diet?
Fat is set at 32% of total calories, which is 657 calories or 73g 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 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.
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 1.2x estimate for sedentary 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.
