Macros for 150 lb Women (Cutting, Lightly Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 150 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 | 150 lbs |
|---|---|
| Estimated Lean Mass | 113 lbs (75% of body weight) |
| Lean Mass (kg) | 51 kg |
| BMR (Katch-McArdle) | 1,472 cal/day |
| TDEE (BMR x 1.375) | 2,023 cal/day |
| Target Calories | 1,619 cal/day |
| Daily Deficit | 404 cal/day (20% deficit) |
| Expected Weekly Change | 0.81 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 | 133g | 532 | 33% |
| Carbohydrates | 103g | 412 | 25% |
| Fat | 75g | 675 | 42% |
| Total | - | 1,619 | 100% |
Protein is set at 2.6g per kg of lean body mass (113 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. 44g per meal in 3 meals is within the optimal range.
What These Macros Look Like in Food
Protein: 133g
- 4 x 100g chicken breast (31g each)
- 22 large eggs (6g each)
- 8 cups whole-milk Greek yogurt (17g each)
- 6 scoops protein powder (22-25g each)
Carbs: 103g
- 2 cups cooked rice (45g each)
- 2 cups dry oats (54g each)
- 4 medium sweet potatoes (26g each)
- 4 medium bananas (27g each)
Fat: 75g
- 5 tbsp olive oil (14g each)
- 5 half avocados (15g each)
- 9 tbsp peanut butter (8g fat each)
- 5 oz almonds (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 150 lb woman cutting to 135 lbs, the TDEE shifts by roughly 151 calories and macros should be recalculated.
What foods hit 133g protein, 75g fat, and 103g carbs?
Protein sources for 133g: roughly 4 x 100g portions of chicken breast (31g protein each), or 22 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 103g: roughly 2 cups of cooked rice (45g each) or 4 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 1619 calorie target?
Your Lightly Active activity level uses a multiplier of 1.375, giving a TDEE of 2023 calories. If you were sedentary (1.2x), your TDEE would be approximately 1766 calories. If you were very active (1.725x), it would be approximately 2539 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 1619 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 1.375x estimate. Confirm tracking accuracy before cutting further.
Losing more than 1.5 lbs per week
Add 100-200 cal/day from carbs. At 150 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 150 lbs when you weigh less will slow progress.
