Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 180 lb man on a cutting 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 | 2,252 cal/day |
| Daily Deficit | 561 cal/day (20% deficit) |
| Expected Weekly Change | 1.12 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 1.55 = moderate exercise 3-5 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 174g | 696 | 31% |
| Carbohydrates | 191g | 764 | 34% |
| Fat | 88g | 792 | 35% |
| Total | - | 2,252 | 100% |
Protein is set at 2.6g per kg of lean body mass (148 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
How long should I stay in a cutting phase at 2252 calories?
Most people cut effectively for 8-16 weeks before needing a break. At 2252 calories, a 180 lb man should lose approximately 1.12 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 2252 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 225 calories on training days and subtract 225 on rest days. Your weekly calorie total stays fixed.
How were the macros calculated for a 180 lb male?
The calculation uses the Katch-McArdle BMR formula. A 180 lb man with an estimated 82% lean mass (148 lbs lean) has a BMR of 1815 calories. Multiplied by 1.55 for moderately active activity (Moderate exercise 3-5 days per week), the TDEE is 2813 calories per day. For cutting, a 20% deficit brings the target to 2252 calories.
Why is protein 174g for cutting at 180 lbs?
Protein for cutting is set at 2.6g per kg of lean body mass. A 180 lb man with 148 lbs of lean mass needs 174g of protein per day. Higher protein during a cut preserves muscle tissue while in a calorie deficit.
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 1.55x estimate. Confirm tracking accuracy before cutting further.
Losing more than 1.5 lbs per week
Add 100-200 cal/day from carbs. At 180 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 180 lbs when you weigh less will slow progress.
