Macros for 150 lb Men (Cutting, Very Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 150 lb man on a cutting diet. Calculated from estimated lean mass, Katch-McArdle BMR, and a very active TDEE (hard exercise 6-7 days per week).

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 1.725) | 2,717 cal/day |
| Target Calories | 2,173 cal/day |
| Daily Deficit | 544 cal/day (20% deficit) |
| Expected Weekly Change | 1.09 lbs loss 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 1.725 = hard exercise 6-7 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 145g | 580 | 27% |
| Carbohydrates | 207g | 828 | 38% |
| Fat | 85g | 765 | 35% |
| Total | - | 2,173 | 100% |
Protein is set at 2.6g per kg of lean body mass (123 lbs lean mass for this man). Fat targets 35% 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 should I do if I'm not losing weight at 2173 calories?
After 2 weeks with no movement, your actual TDEE likely differs from the estimate. Try reducing by 100-150 calories first. If energy drops significantly, check your protein intake before cutting calories further. Common issue: overestimating activity level.
How long should I stay in a cutting phase at 2173 calories?
Most people cut effectively for 8-16 weeks before needing a break. At 2173 calories, a 150 lb man should lose approximately 1.09 lbs per week. After 10-12 weeks, take a 4-8 week maintenance break to reset ghrelin and cortisol before cutting again.
Should I eat more on training days at 2173 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 217 calories on training days and subtract 217 on rest days. Your weekly calorie total stays fixed.
How were the macros calculated for a 150 lb male?
The calculation uses the Katch-McArdle BMR formula. A 150 lb man with an estimated 82% lean mass (123 lbs lean) has a BMR of 1575 calories. Multiplied by 1.725 for very active activity (Hard exercise 6-7 days per week), the TDEE is 2717 calories per day. For cutting, a 20% deficit brings the target to 2173 calories.
When to Recalculate These Macros
Not losing weight after 2 consistent weeks
Reduce by 100-150 cal/day, pulling from carbs first. Your actual TDEE may be slightly below the 1.725x estimate. Confirm tracking accuracy before cutting further.
Losing more than 1.5 lbs per week
Add 100-200 cal/day from carbs. At 150 lbs, faster loss increases muscle loss risk and energy crashes. The target rate is 0.5-1 lb per week on a cut.
Lost 10 or more lbs from this starting weight
Recalculate at your new weight. BMR and TDEE drop as you lose mass. Eating the macros for 150 lbs when you weigh less will slow progress.
