Macros for 230 lb Men (Maintenance, Moderately 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 moderately active TDEE (moderate exercise 3-5 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 1.55) | 3,436 cal/day |
| Target Calories | 3,435 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 1.55 = moderate exercise 3-5 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 197g | 788 | 23% |
| Carbohydrates | 403g | 1612 | 47% |
| Fat | 115g | 1035 | 30% |
| Total | - | 3,435 | 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.

These are rough equivalents. Most meals contain a mix of all three macros. Use a food tracking app for precise logging.
These numbers use an estimated 18% body fat.

Frequently Asked Questions
Should I recalculate my macros as I track weight?
At maintenance, recalculate your TDEE every 4-8 weeks if your weight shifts more than 5 lbs consistently. Lean mass changes affect calorie needs.
What foods hit 197g protein, 115g fat, and 403g carbs?
Protein sources for 197g: roughly 6 x 100g portions of chicken breast (31g protein each), or 33 eggs (6g each), combined with Greek yogurt or protein powder. Fat sources for 115g: about 8 tablespoons of olive oil or peanut butter. Carb sources for 403g: roughly 9 cups of cooked rice (45g each) or 15 cups of oats (27g each). A food tracking app is the most accurate way to hit these targets.
How does my activity level affect my 3435 calorie target?
Your Moderately Active activity level uses a multiplier of 1.55, giving a TDEE of 3436 calories. If you were sedentary (1.2x), your TDEE would be approximately 2660 calories. If you were very active (1.725x), it would be approximately 3824 calories. The activity multiplier is the single biggest variable in your calorie target. Getting it right matters more than small differences in the macro split.
What should I do if I'm not maintaining weight at 3435 calories?
If your weight trends up or down consistently over 2 weeks at 3435 calories, your actual TDEE differs from the estimate. Adjust by 100 calories in the direction that corrects the trend. Recalculate every time you change activity level significantly.
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 1.55x estimate for moderately 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.
