Macros for 140 lb Women (Maintenance, Sedentary)
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 sedentary TDEE (desk job, little or no exercise).

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 1.2) | 1,678 cal/day |
| Target Calories | 1,677 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 | 109g | 436 | 26% |
| Carbohydrates | 182g | 728 | 43% |
| Fat | 57g | 513 | 31% |
| Total | - | 1,677 | 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
What should I do if I'm not maintaining weight at 1677 calories?
If your weight trends up or down consistently over 2 weeks at 1677 calories, your actual TDEE differs from the estimate. Adjust by 100 calories in the direction that corrects the trend. Recalculate every time you change activity level significantly.
How long should I stay in a maintenance phase at 1677 calories?
Maintenance phases should last 4-8 weeks between a cut and a bulk. They reset hunger hormones, establish a new weight set point, and give your body a break from the stress of a deficit or surplus.
Should I eat more on training days at 1677 calories?
Cycling calories is not necessary for most people. Hitting your daily target consistently produces better results than complex cycling protocols. If you want to cycle, shift 10-15% of daily calories from rest days to training days while keeping the weekly total the same. For example, add 168 calories on training days and subtract 168 on rest days. Your weekly calorie total stays fixed.
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 1.2 for sedentary activity (Desk job, little or no exercise), the TDEE is 1678 calories per day. For maintenance, the target matches TDEE at 1677 calories.
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 140 lbs.
