Macros for 160 lb Men (Bulking, Extra Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 160 lb man on a bulking diet. Calculated from estimated lean mass, Katch-McArdle BMR, and a extra active TDEE (very hard exercise and physical job).

How These Macros Were Calculated
| Body Weight | 160 lbs |
|---|---|
| Estimated Lean Mass | 131 lbs (82% of body weight) |
| Lean Mass (kg) | 59.5 kg |
| BMR (Katch-McArdle) | 1,655 cal/day |
| TDEE (BMR x 1.9) | 3,145 cal/day |
| Target Calories | 3,459 cal/day |
| Daily Surplus | 314 cal/day (10% surplus) |
| Expected Weekly Change | 0.63 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 1.9 = very hard exercise and physical job.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 137g | 548 | 16% |
| Carbohydrates | 469g | 1876 | 54% |
| Fat | 115g | 1035 | 30% |
| Total | - | 3,459 | 100% |
Protein is set at 2.3g per kg of lean body mass (131 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 fat set at 115g for a bulking diet?
Fat is set at 30% of total calories, which is 1035 calories or 115g 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 137g of protein across meals?
Across 3 meals, each meal needs about 46g of protein. Across 5 meals or snacks, each needs about 27g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 46g per meal in 3 meals is within the optimal 30-40g range.
What are 469g of carbs used for in a bulking diet?
The 469g of carbs provides 1876 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. On a bulk, 469g of carbs drives the calorie surplus needed for muscle growth. Rice, oats, and potatoes are the most efficient sources.
Should I recalculate my macros as I gain weight?
Yes. Recalculate every 10-15 lbs of weight gain. As your weight changes, lean mass, BMR, and TDEE all shift. For a 160 lb man bulking to 175 lbs, the TDEE shifts by roughly 230 calories and macros should be recalculated.
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 1.9x 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.
