Macros for 140 lb Men (Bulking, Moderately Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 140 lb man on a bulking 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 | 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 1.55) | 2,318 cal/day |
| Target Calories | 2,549 cal/day |
| Daily Surplus | 231 cal/day (10% surplus) |
| Expected Weekly Change | 0.46 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 1.55 = moderate exercise 3-5 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 120g | 480 | 19% |
| Carbohydrates | 326g | 1304 | 51% |
| Fat | 85g | 765 | 30% |
| Total | - | 2,549 | 100% |
Protein is set at 2.3g per kg of lean body mass (115 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 should I do if I'm not gaining weight at 2549 calories?
After 2 weeks with no movement, your actual TDEE likely differs from the estimate. Add 100-150 calories, prioritizing carbs. Gaining too fast (more than 1 lb/week)? Cut 100-150 calories. The target assumes moderately active activity.
How long should I stay in a bulking phase at 2549 calories?
Lean bulks typically run 12-20 weeks. At 2549 calories, expect gradual muscle gain with minimal fat. When body fat feels high (above 18-20% for men, 28-30% for women), transition to maintenance or a cut.
Should I eat more on training days at 2549 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 255 calories on training days and subtract 255 on rest days. Your weekly calorie total stays fixed.
How were the macros calculated for a 140 lb male?
The calculation uses the Katch-McArdle BMR formula. A 140 lb man with an estimated 82% lean mass (115 lbs lean) has a BMR of 1495 calories. Multiplied by 1.55 for moderately active activity (Moderate exercise 3-5 days per week), the TDEE is 2318 calories per day. For bulking, a 10% surplus brings the target to 2549 calories.
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 1.55x 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.
