Macros for 140 lb Men (Cutting, Sedentary)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 140 lb man on a cutting diet. Calculated from estimated lean mass, Katch-McArdle BMR, and a sedentary TDEE (desk job, little or no exercise).

How These Macros Were Calculated
| Body Weight | 140 lbs |
|---|---|
| Estimated Lean Mass | 115 lbs (82% of body weight) |
| Lean Mass (kg) | 52.1 kg |
| BMR (Katch-McArdle) | 1,495 cal/day |
| TDEE (BMR x 1.2) | 1,794 cal/day |
| Target Calories | 1,437 cal/day |
| Daily Deficit | 357 cal/day (20% deficit) |
| Expected Weekly Change | 0.71 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 1.2 = desk job, little or no exercise.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 135g | 540 | 37% |
| Carbohydrates | 96g | 384 | 27% |
| Fat | 57g | 513 | 36% |
| Total | - | 1,437 | 100% |
Protein is set at 2.6g per kg of lean body mass (115 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 does my activity level affect my 1437 calorie target?
Your Sedentary activity level uses a multiplier of 1.2, giving a TDEE of 1794 calories. If you were sedentary (1.2x), your TDEE would be approximately 1794 calories. If you were very active (1.725x), it would be approximately 2579 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.
What should I do if I'm not losing weight at 1437 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 1437 calories?
Most people cut effectively for 8-16 weeks before needing a break. At 1437 calories, a 140 lb man should lose approximately 0.71 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 1437 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 144 calories on training days and subtract 144 on rest days. Your weekly calorie total stays fixed.
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 1.2x estimate. Confirm tracking accuracy before cutting further.
Losing more than 1.5 lbs per week
Add 100-200 cal/day from carbs. At 140 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 140 lbs when you weigh less will slow progress.
