Macros for 230 lb Women (Cutting, Very Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 230 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 | 230 lbs |
|---|---|
| Estimated Lean Mass | 173 lbs (75% of body weight) |
| Lean Mass (kg) | 78.2 kg |
| BMR (Katch-McArdle) | 2,059 cal/day |
| TDEE (BMR x 1.725) | 3,552 cal/day |
| Target Calories | 2,843 cal/day |
| Daily Deficit | 709 cal/day (20% deficit) |
| Expected Weekly Change | 1.42 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 | 203g | 812 | 29% |
| Carbohydrates | 249g | 996 | 35% |
| Fat | 115g | 1035 | 36% |
| Total | - | 2,843 | 100% |
Protein is set at 2.6g per kg of lean body mass (173 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 were the macros calculated for a 230 lb female?
The calculation uses the Katch-McArdle BMR formula. A 230 lb woman with an estimated 75% lean mass (173 lbs lean) has a BMR of 2059 calories. Multiplied by 1.725 for very active activity (Hard exercise 6-7 days per week), the TDEE is 3552 calories per day. For cutting, a 20% deficit brings the target to 2843 calories.
Why is protein 203g for cutting at 230 lbs?
Protein for cutting is set at 2.6g per kg of lean body mass. A 230 lb woman with 173 lbs of lean mass needs 203g of protein per day. Higher protein during a cut preserves muscle tissue while in a calorie deficit.
How much weight will I lose at 2843 calories?
At 2843 calories per day, a 230 lb woman should lose approximately 1.42 lbs per week. This assumes a TDEE of 3552 at very active activity and a deficit of 709 calories per day. Results vary based on actual metabolic rate, training load, and adherence.
Why is fat set at 115g for a cutting diet?
Fat is set at 36% of total calories, which is 1035 calories or 115g per day. Fat is essential for hormone production, fat-soluble vitamin absorption, and satiety. During a deficit, fat is set at or above 35% of target calories to protect hormonal function and satiety while losing weight. Dropping fat below 20% of total calories can impair testosterone, estrogen, and recovery.
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 230 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 230 lbs when you weigh less will slow progress.
