Macros for 150 lb Men (Bulking, Extra Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 150 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 | 150 lbs |
|---|---|
| Estimated Lean Mass | 123 lbs (82% of body weight) |
| Lean Mass (kg) | 55.8 kg |
| BMR (Katch-McArdle) | 1,575 cal/day |
| TDEE (BMR x 1.9) | 2,993 cal/day |
| Target Calories | 3,294 cal/day |
| Daily Surplus | 301 cal/day (10% surplus) |
| Expected Weekly Change | 0.6 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 | 128g | 512 | 16% |
| Carbohydrates | 448g | 1792 | 54% |
| Fat | 110g | 990 | 30% |
| Total | - | 3,294 | 100% |
Protein is set at 2.3g per kg of lean body mass (123 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
What are 448g of carbs used for in a bulking diet?
The 448g of carbs provides 1792 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. On a bulk, 448g 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 150 lb man bulking to 165 lbs, the TDEE shifts by roughly 230 calories and macros should be recalculated.
What foods hit 128g protein, 110g fat, and 448g carbs?
Protein sources for 128g: roughly 4 x 100g portions of chicken breast (31g protein each), or 21 eggs (6g each), combined with Greek yogurt or protein powder. Fat sources for 110g: about 8 tablespoons of olive oil or peanut butter. Carb sources for 448g: roughly 10 cups of cooked rice (45g each) or 17 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 3294 calorie target?
Your Extra Active activity level uses a multiplier of 1.9, giving a TDEE of 2993 calories. If you were sedentary (1.2x), your TDEE would be approximately 1890 calories. If you were very active (1.725x), it would be approximately 2717 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.
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.
