Macros for 160 lb Women (Bulking, Lightly Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 160 lb woman on a bulking 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 | 2,338 cal/day |
| Daily Surplus | 214 cal/day (10% surplus) |
| Expected Weekly Change | 0.43 lbs gain 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 | 125g | 500 | 21% |
| Carbohydrates | 284g | 1136 | 49% |
| Fat | 78g | 702 | 30% |
| Total | - | 2,338 | 100% |
Protein is set at 2.3g per kg of lean body mass (120 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.

Research shows muscle protein synthesis is maximized with 30-40g protein per meal. 42g per meal in 3 meals is within the optimal range.
What These Macros Look Like in Food
Protein: 125g
- 4 x 100g chicken breast (31g each)
- 21 large eggs (6g each)
- 7 cups whole-milk Greek yogurt (17g each)
- 5 scoops protein powder (22-25g each)
Carbs: 284g
- 6 cups cooked rice (45g each)
- 5 cups dry oats (54g each)
- 11 medium sweet potatoes (26g each)
- 11 medium bananas (27g each)
Fat: 78g
- 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
What foods hit 125g protein, 78g fat, and 284g carbs?
Protein sources for 125g: 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 78g: about 6 tablespoons of olive oil or peanut butter. Carb sources for 284g: roughly 6 cups of cooked rice (45g each) or 11 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 2338 calorie target?
Your Lightly Active activity level uses a multiplier of 1.375, giving a TDEE of 2124 calories. If you were sedentary (1.2x), your TDEE would be approximately 1854 calories. If you were very active (1.725x), it would be approximately 2665 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 gaining weight at 2338 calories?
After 2 weeks with no movement, your actual TDEE likely differs from the estimate. Add 100-150 calories, prioritizing carbs. Gaining too fast (more than 1 lb/week)? Cut 100-150 calories. The target assumes lightly active activity.
How long should I stay in a bulking phase at 2338 calories?
Lean bulks typically run 12-20 weeks. At 2338 calories, expect gradual muscle gain with minimal fat. When body fat feels high (above 18-20% for men, 28-30% for women), transition to maintenance or a cut.
When to Recalculate These Macros
Not gaining weight after 2 consistent weeks
Add 100-150 cal/day from carbs. Your TDEE may be higher than the 1.375x estimate. Confirm you are tracking consistently before increasing further.
Gaining more than 1 lb per week
Reduce by 100-150 cal/day. Muscle growth rate is limited by biology. Excess surplus above that ceiling goes to fat. Target 0.25-0.5 lbs per week for a lean bulk.
Gained 10 or more lbs from this starting weight
Recalculate at your new weight. Higher mass means higher TDEE, so the same surplus percentage shrinks over time without adjustments.
