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 1.2) | 2,471 cal/day |
| Target Calories | 2,718 cal/day |
| Daily Surplus | 247 cal/day (10% surplus) |
| Expected Weekly Change | 0.49 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 | 180g | 720 | 27% |
| Carbohydrates | 288g | 1152 | 42% |
| Fat | 94g | 846 | 31% |
| Total | - | 2,718 | 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
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 1.2 for sedentary activity (Desk job, little or no exercise), the TDEE is 2471 calories per day. For bulking, a 10% surplus brings the target to 2718 calories.
Why is protein 180g for bulking at 230 lbs?
Protein for bulking 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. 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 2718 calories?
At 2718 calories per day, a 230 lb woman should gain approximately 0.49 lbs per week. This assumes a TDEE of 2471 at sedentary activity and a surplus of 247 calories per day. Results vary based on actual metabolic rate, training load, and adherence.
Why is fat set at 94g for a bulking diet?
Fat is set at 31% of total calories, which is 846 calories or 94g 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 1.2x 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.
