Macros for 140 lb Women (Cutting, Lightly Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 140 lb woman on a cutting diet. Calculated from estimated lean mass, Katch-McArdle BMR, and a lightly active TDEE (light exercise 1-3 days per week).

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 1.375) | 1,922 cal/day |
| Target Calories | 1,538 cal/day |
| Daily Deficit | 384 cal/day (20% deficit) |
| Expected Weekly Change | 0.77 lbs loss per week |
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 1.375 = light exercise 1-3 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 124g | 496 | 32% |
| Carbohydrates | 103g | 412 | 27% |
| Fat | 70g | 630 | 41% |
| Total | - | 1,538 | 100% |
Protein is set at 2.6g per kg of lean body mass (105 lbs lean mass for this woman). Fat targets 35% 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 does my activity level affect my 1538 calorie target?
Your Lightly Active activity level uses a multiplier of 1.375, giving a TDEE of 1922 calories. If you were sedentary (1.2x), your TDEE would be approximately 1678 calories. If you were very active (1.725x), it would be approximately 2412 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.
What should I do if I'm not losing weight at 1538 calories?
After 2 weeks with no movement, your actual TDEE likely differs from the estimate. Try reducing by 100-150 calories first. If energy drops significantly, check your protein intake before cutting calories further. Common issue: overestimating activity level.
How long should I stay in a cutting phase at 1538 calories?
Most people cut effectively for 8-16 weeks before needing a break. At 1538 calories, a 140 lb woman should lose approximately 0.77 lbs per week. After 10-12 weeks, take a 4-8 week maintenance break to reset ghrelin and cortisol before cutting again.
Should I eat more on training days at 1538 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 154 calories on training days and subtract 154 on rest days. Your weekly calorie total stays fixed.
When to Recalculate These Macros
Not losing weight after 2 consistent weeks
Reduce by 100-150 cal/day, pulling from carbs first. Your actual TDEE may be slightly below the 1.375x estimate. Confirm tracking accuracy before cutting further.
Losing more than 1.5 lbs per week
Add 100-200 cal/day from carbs. At 140 lbs, faster loss increases muscle loss risk and energy crashes. The target rate is 0.5-1 lb per week on a cut.
Lost 10 or more lbs from this starting weight
Recalculate at your new weight. BMR and TDEE drop as you lose mass. Eating the macros for 140 lbs when you weigh less will slow progress.
