Macros for 180 lb Women (Bulking, Sedentary)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 180 lb woman on a bulking diet. Calculated from estimated lean mass, Katch-McArdle BMR, and a sedentary TDEE (desk job, little or no exercise).

How These Macros Were Calculated
| Body Weight | 180 lbs |
|---|---|
| Estimated Lean Mass | 135 lbs (75% of body weight) |
| Lean Mass (kg) | 61.2 kg |
| BMR (Katch-McArdle) | 1,692 cal/day |
| TDEE (BMR x 1.2) | 2,030 cal/day |
| Target Calories | 2,234 cal/day |
| Daily Surplus | 204 cal/day (10% surplus) |
| Expected Weekly Change | 0.41 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 1.2 = desk job, little or no exercise.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 141g | 564 | 25% |
| Carbohydrates | 251g | 1004 | 45% |
| Fat | 74g | 666 | 30% |
| Total | - | 2,234 | 100% |
Protein is set at 2.3g per kg of lean body mass (135 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 long should I stay in a bulking phase at 2234 calories?
Lean bulks typically run 12-20 weeks. At 2234 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.
Should I eat more on training days at 2234 calories?
Cycling calories is not necessary for most people. Hitting your daily target consistently produces better results than complex cycling protocols. If you want to cycle, shift 10-15% of daily calories from rest days to training days while keeping the weekly total the same. For example, add 223 calories on training days and subtract 223 on rest days. Your weekly calorie total stays fixed.
How were the macros calculated for a 180 lb female?
The calculation uses the Katch-McArdle BMR formula. A 180 lb woman with an estimated 75% lean mass (135 lbs lean) has a BMR of 1692 calories. Multiplied by 1.2 for sedentary activity (Desk job, little or no exercise), the TDEE is 2030 calories per day. For bulking, a 10% surplus brings the target to 2234 calories.
Why is protein 141g for bulking at 180 lbs?
Protein for bulking is set at 2.3g per kg of lean body mass. A 180 lb woman with 135 lbs of lean mass needs 141g of protein per day. During a bulk, 2.3g per kg of lean mass supports muscle protein synthesis without excess calories from protein.
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 1.2x 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.
