Macros for 180 lb Women (Cutting, Very Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 180 lb woman on a cutting diet. Calculated from estimated lean mass, Katch-McArdle BMR, and a very active TDEE (hard exercise 6-7 days per week).

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 1.725) | 2,919 cal/day |
| Target Calories | 2,335 cal/day |
| Daily Deficit | 584 cal/day (20% deficit) |
| Expected Weekly Change | 1.17 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 1.725 = hard exercise 6-7 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 159g | 636 | 27% |
| Carbohydrates | 220g | 880 | 38% |
| Fat | 91g | 819 | 35% |
| Total | - | 2,335 | 100% |
Protein is set at 2.6g per kg of lean body mass (135 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.

Frequently Asked Questions
How long should I stay in a cutting phase at 2335 calories?
Most people cut effectively for 8-16 weeks before needing a break. At 2335 calories, a 180 lb woman should lose approximately 1.17 lbs per week. After 10-12 weeks, take a 4-8 week maintenance break to reset ghrelin and cortisol before cutting again.
Should I eat more on training days at 2335 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 234 calories on training days and subtract 234 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 1.725 for very active activity (Hard exercise 6-7 days per week), the TDEE is 2919 calories per day. For cutting, a 20% deficit brings the target to 2335 calories.
Why is protein 159g for cutting at 180 lbs?
Protein for cutting is set at 2.6g per kg of lean body mass. A 180 lb woman with 135 lbs of lean mass needs 159g of protein per day. Higher protein during a cut preserves muscle tissue while in a calorie deficit.
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 1.725x estimate. Confirm tracking accuracy before cutting further.
Losing more than 1.5 lbs per week
Add 100-200 cal/day from carbs. At 180 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 180 lbs when you weigh less will slow progress.
