Macros for 230 lb Men (Maintenance, Very Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 230 lb man on a maintenance diet. Calculated from estimated lean mass, Katch-McArdle BMR, and a very active TDEE (hard exercise 6-7 days per week).

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 | 189 lbs (82% of body weight) |
| Lean Mass (kg) | 85.5 kg |
| BMR (Katch-McArdle) | 2,217 cal/day |
| TDEE (BMR x 1.725) | 3,824 cal/day |
| Target Calories | 3,823 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 18% average body fat for men. Activity multiplier 1.725 = hard exercise 6-7 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 197g | 788 | 21% |
| Carbohydrates | 473g | 1892 | 49% |
| Fat | 127g | 1143 | 30% |
| Total | - | 3,823 | 100% |
Protein is set at 2.3g per kg of lean body mass (189 lbs lean mass for this man). 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 3823 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 382 calories on training days and subtract 382 on rest days. Your weekly calorie total stays fixed.
How were the macros calculated for a 230 lb male?
The calculation uses the Katch-McArdle BMR formula. A 230 lb man with an estimated 82% lean mass (189 lbs lean) has a BMR of 2217 calories. Multiplied by 1.725 for very active activity (Hard exercise 6-7 days per week), the TDEE is 3824 calories per day. For maintenance, the target matches TDEE at 3823 calories.
Why is protein 197g for maintenance at 230 lbs?
Protein for maintenance is set at 2.3g per kg of lean body mass. A 230 lb man with 189 lbs of lean mass needs 197g 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 3823 calories?
At 3823 calories per day, your weight should stay stable within normal daily fluctuation (1-3 lbs of water weight). This is your estimated TDEE for very 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 1.725x estimate for very 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.
