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 moderately active TDEE (moderate exercise 3-5 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 1.55) | 2,395 cal/day |
| Target Calories | 2,636 cal/day |
| Daily Surplus | 241 cal/day (10% surplus) |
| Expected Weekly Change | 0.48 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 1.55 = moderate exercise 3-5 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 125g | 500 | 19% |
| Carbohydrates | 336g | 1344 | 51% |
| Fat | 88g | 792 | 30% |
| Total | - | 2,636 | 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.

Frequently Asked Questions
How were the macros calculated for a 160 lb female?
The calculation uses the Katch-McArdle BMR formula. A 160 lb woman with an estimated 75% lean mass (120 lbs lean) has a BMR of 1545 calories. Multiplied by 1.55 for moderately active activity (Moderate exercise 3-5 days per week), the TDEE is 2395 calories per day. For bulking, a 10% surplus brings the target to 2636 calories.
Why is protein 125g for bulking at 160 lbs?
Protein for bulking is set at 2.3g per kg of lean body mass. A 160 lb woman with 120 lbs of lean mass needs 125g of protein per day. During a bulk, 2.3g per kg of lean mass supports muscle protein synthesis without excess calories from protein.
How much weight will I gain at 2636 calories?
At 2636 calories per day, a 160 lb woman should gain approximately 0.48 lbs per week. This assumes a TDEE of 2395 at moderately active activity and a surplus of 241 calories per day. Results vary based on actual metabolic rate, training load, and adherence.
Why is fat set at 88g for a bulking diet?
Fat is set at 30% of total calories, which is 792 calories or 88g per day. Fat is essential for hormone production, fat-soluble vitamin absorption, and satiety. Keeping fat at 30% of calories maintains hormone function during a calorie surplus. Dropping fat below 20% of total calories can impair testosterone, estrogen, and recovery.
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 1.55x 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.
