Macros for 140 lb Women (Cutting, Very 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 very active TDEE (hard exercise 6-7 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 1.725) | 2,412 cal/day |
| Target Calories | 1,931 cal/day |
| Daily Deficit | 481 cal/day (20% deficit) |
| Expected Weekly Change | 0.96 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 1.725 = hard exercise 6-7 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 124g | 496 | 26% |
| Carbohydrates | 190g | 760 | 39% |
| Fat | 75g | 675 | 35% |
| Total | - | 1,931 | 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.

Research shows muscle protein synthesis is maximized with 30-40g protein per meal. 41g per meal in 3 meals is within the optimal range.
What These Macros Look Like in Food
Protein: 124g
- 5 scoops protein powder (22-25g each)
- 4 x 100g chicken breast (31g each)
- 5 x 100g lean ground beef (26g each)
- 21 large eggs (6g each)
Carbs: 190g
- 4 cups cooked white rice (45g each)
- 7 medium bananas (27g each)
- 4 cups dry oats (54g each)
- 27 rice cakes (7g each)
Fat: 75g
- 5 tbsp olive oil (14g each)
- 8 tbsp almond butter (9g fat each)
- 4 oz walnuts (18g each)
- 5 tbsp coconut oil (14g each)
These are rough equivalents. Most meals contain a mix of all three macros. Use a food tracking app for precise logging.
These numbers use an estimated 25% body fat.

Frequently Asked Questions
Should I recalculate my macros as I lose weight?
Yes. Recalculate every 10-15 lbs of weight loss. As your weight changes, lean mass, BMR, and TDEE all shift. For a 140 lb woman cutting to 125 lbs, the TDEE shifts by roughly 190 calories and macros should be recalculated.
What foods hit 124g protein, 75g fat, and 190g carbs?
Protein sources for 124g: roughly 4 x 100g portions of chicken breast (31g protein each), or 21 eggs (6g each), combined with Greek yogurt or protein powder. Fat sources for 75g: about 5 tablespoons of olive oil or peanut butter. Carb sources for 190g: roughly 4 cups of cooked rice (45g each) or 7 cups of oats (27g each). A food tracking app is the most accurate way to hit these targets.
How does my activity level affect my 1931 calorie target?
Your Very Active activity level uses a multiplier of 1.725, giving a TDEE of 2412 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 1931 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.
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 1.725x 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.
