Macros for 160 lb Women (Cutting, Lightly Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 160 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 | 160 lbs |
|---|---|
| Estimated Lean Mass | 120 lbs (75% of body weight) |
| Lean Mass (kg) | 54.4 kg |
| BMR (Katch-McArdle) | 1,545 cal/day |
| TDEE (BMR x 1.375) | 2,124 cal/day |
| Target Calories | 1,700 cal/day |
| Daily Deficit | 424 cal/day (20% deficit) |
| Expected Weekly Change | 0.85 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 | 141g | 564 | 33% |
| Carbohydrates | 104g | 416 | 25% |
| Fat | 80g | 720 | 42% |
| Total | - | 1,700 | 100% |
Protein is set at 2.6g per kg of lean body mass (120 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. 47g per meal in 3 meals is within the optimal range.
What These Macros Look Like in Food
Protein: 141g
- 5 x 100g chicken breast (31g each)
- 24 large eggs (6g each)
- 8 cups whole-milk Greek yogurt (17g each)
- 6 scoops protein powder (22-25g each)
Carbs: 104g
- 2 cups cooked rice (45g each)
- 2 cups dry oats (54g each)
- 4 medium sweet potatoes (26g each)
- 4 medium bananas (27g each)
Fat: 80g
- 6 tbsp olive oil (14g each)
- 5 half avocados (15g each)
- 10 tbsp peanut butter (8g fat each)
- 6 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
How do I split 141g of protein across meals?
Across 3 meals, each meal needs about 47g of protein. Across 5 meals or snacks, each needs about 28g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 47g per meal in 3 meals is within the optimal 30-40g range.
What are 104g of carbs used for in a cutting diet?
The 104g of carbs provides 416 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. On a cut, carbs fill the remaining calories after protein and fat. At 104g, this is a moderate-carb cut, not a low-carb diet.
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 160 lb woman cutting to 145 lbs, the TDEE shifts by roughly 151 calories and macros should be recalculated.
What foods hit 141g protein, 80g fat, and 104g carbs?
Protein sources for 141g: roughly 5 x 100g portions of chicken breast (31g protein each), or 24 eggs (6g each), combined with Greek yogurt or protein powder. Fat sources for 80g: about 6 tablespoons of olive oil or peanut butter. Carb sources for 104g: 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.
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 160 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 160 lbs when you weigh less will slow progress.
