Macros for 140 lb Women (Maintenance, Very Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 140 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 140 lb body weight while optimizing protein for muscle retention.
How These Macros Were Calculated
| Body Weight | 140 lbs |
|---|---|
| Estimated Lean Mass | 105 lbs (75% of body weight) |
| Lean Mass (kg) | 47.6 kg |
| BMR (Katch-McArdle) | 1,398 cal/day |
| TDEE (BMR x 1.725) | 2,412 cal/day |
| Target Calories | 2,412 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 | 109g | 436 | 18% |
| Carbohydrates | 314g | 1256 | 52% |
| Fat | 80g | 720 | 30% |
| Total | - | 2,412 | 100% |
Protein is set at 2.3g per kg of lean body mass (105 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 were the macros calculated for a 140 lb female?
The calculation uses the Katch-McArdle BMR formula. A 140 lb woman with an estimated 75% lean mass (105 lbs lean) has a BMR of 1398 calories. Multiplied by 1.725 for very active activity (Hard exercise 6-7 days per week), the TDEE is 2412 calories per day. For maintenance, the target matches TDEE at 2412 calories.
Why is protein 109g for maintenance at 140 lbs?
Protein for maintenance is set at 2.3g per kg of lean body mass. A 140 lb woman with 105 lbs of lean mass needs 109g 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 2412 calories?
At 2412 calories per day, your weight should stay stable within normal daily fluctuation (1-3 lbs of water weight). This is your estimated TDEE for very active activity. If you consistently gain or lose weight at this intake, your actual TDEE differs from the estimate.
Why is fat set at 80g for a maintenance diet?
Fat is set at 30% of total calories, which is 720 calories or 80g 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.
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 140 lbs.
