Macros for 180 lb Men (Bulking, Moderately Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 180 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 | 180 lbs |
|---|---|
| Estimated Lean Mass | 148 lbs (82% of body weight) |
| Lean Mass (kg) | 66.9 kg |
| BMR (Katch-McArdle) | 1,815 cal/day |
| TDEE (BMR x 1.55) | 2,813 cal/day |
| Target Calories | 3,095 cal/day |
| Daily Surplus | 282 cal/day (10% surplus) |
| Expected Weekly Change | 0.56 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 | 154g | 616 | 20% |
| Carbohydrates | 388g | 1552 | 50% |
| Fat | 103g | 927 | 30% |
| Total | - | 3,095 | 100% |
Protein is set at 2.3g per kg of lean body mass (148 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
Why is protein 154g for bulking at 180 lbs?
Protein for bulking is set at 2.3g per kg of lean body mass. A 180 lb man with 148 lbs of lean mass needs 154g 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 3095 calories?
At 3095 calories per day, a 180 lb man should gain approximately 0.56 lbs per week. This assumes a TDEE of 2813 at moderately active activity and a surplus of 282 calories per day. Results vary based on actual metabolic rate, training load, and adherence.
Why is fat set at 103g for a bulking diet?
Fat is set at 30% of total calories, which is 927 calories or 103g 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.
How do I split 154g of protein across meals?
Across 3 meals, each meal needs about 51g of protein. Across 5 meals or snacks, each needs about 31g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 51g per meal in 3 meals is within the optimal 30-40g range.
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.
