Macros for 250 lb Men (Bulking, Moderately Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 250 lb man on a bulking diet. Calculated from estimated lean mass, Katch-McArdle BMR, and a moderately active TDEE (moderate exercise 3-5 days per week).

How These Macros Were Calculated
| Body Weight | 250 lbs |
|---|---|
| Estimated Lean Mass | 205 lbs (82% of body weight) |
| Lean Mass (kg) | 93 kg |
| BMR (Katch-McArdle) | 2,379 cal/day |
| TDEE (BMR x 1.55) | 3,687 cal/day |
| Target Calories | 4,055 cal/day |
| Daily Surplus | 368 cal/day (10% surplus) |
| Expected Weekly Change | 0.74 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 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 | 214g | 856 | 21% |
| Carbohydrates | 496g | 1984 | 49% |
| Fat | 135g | 1215 | 30% |
| Total | - | 4,055 | 100% |
Protein is set at 2.3g per kg of lean body mass (205 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 4055 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 406 calories on training days and subtract 406 on rest days. Your weekly calorie total stays fixed.
How were the macros calculated for a 250 lb male?
The calculation uses the Katch-McArdle BMR formula. A 250 lb man with an estimated 82% lean mass (205 lbs lean) has a BMR of 2379 calories. Multiplied by 1.55 for moderately active activity (Moderate exercise 3-5 days per week), the TDEE is 3687 calories per day. For bulking, a 10% surplus brings the target to 4055 calories.
Why is protein 214g for bulking at 250 lbs?
Protein for bulking is set at 2.3g per kg of lean body mass. A 250 lb man with 205 lbs of lean mass needs 214g 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 4055 calories?
At 4055 calories per day, a 250 lb man should gain approximately 0.74 lbs per week. This assumes a TDEE of 3687 at moderately active activity and a surplus of 368 calories per day. Results vary based on actual metabolic rate, training load, and adherence.
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 1.55x 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.
