Macros for 230 lb Women (Maintenance, Extra Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 230 lb woman on a maintenance diet. Calculated from estimated lean mass, Katch-McArdle BMR, and a extra active TDEE (very hard exercise and physical job).

Eating at TDEE with zero deficit or surplus. These macros maintain your 230 lb body weight while optimizing protein for muscle retention.
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 1.9) | 3,912 cal/day |
| Target Calories | 3,914 cal/day |
| Calorie Change | None (maintenance) |
| Expected Weekly Change | Stable weight |
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 1.9 = very hard exercise and physical job.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 180g | 720 | 18% |
| Carbohydrates | 506g | 2024 | 52% |
| Fat | 130g | 1170 | 30% |
| Total | - | 3,914 | 100% |
Protein is set at 2.3g per kg of lean body mass (173 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
Should I eat more on training days at 3914 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 391 calories on training days and subtract 391 on rest days. Your weekly calorie total stays fixed.
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 1.9 for extra active activity (Very hard exercise and physical job), the TDEE is 3912 calories per day. For maintenance, the target matches TDEE at 3914 calories.
Why is protein 180g for maintenance at 230 lbs?
Protein for maintenance is set at 2.3g per kg of lean body mass. A 230 lb woman with 173 lbs of lean mass needs 180g of protein per day. At maintenance, 2.3g per kg of lean mass supports daily muscle repair and satiety.
How much weight will I change at 3914 calories?
At 3914 calories per day, your weight should stay stable within normal daily fluctuation (1-3 lbs of water weight). This is your estimated TDEE for extra active activity. If you consistently gain or lose weight at this intake, your actual TDEE differs from the estimate.
When to Recalculate These Macros
Weight trending upward over 2 weeks
Reduce by 100-150 cal/day from carbs. Your actual TDEE is slightly below the 1.9x estimate for extra active activity.
Weight trending downward over 2 weeks
Add 100-150 cal/day from carbs or fat. You may be more active than the multiplier accounts for, or your metabolism has adapted upward.
Activity level has changed significantly
Switch to the matching activity level using the selector above. The difference between sedentary and moderately active can be 300-500 cal/day at 230 lbs.
