Macros for 140 lb Men (Cutting, Extra Active)
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 extra active TDEE (very hard exercise and physical job).

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 1.9) | 2,841 cal/day |
| Target Calories | 2,272 cal/day |
| Daily Deficit | 569 cal/day (20% deficit) |
| Expected Weekly Change | 1.14 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 1.9 = very hard exercise and physical job.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 135g | 540 | 24% |
| Carbohydrates | 235g | 940 | 41% |
| Fat | 88g | 792 | 35% |
| Total | - | 2,272 | 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.

Research shows muscle protein synthesis is maximized with 30-40g protein per meal. 45g per meal in 3 meals is within the optimal range.
What These Macros Look Like in Food
Protein: 135g
- 6 scoops protein powder (22-25g each)
- 5 x 100g cooked salmon fillet (25g each)
- 4 x 100g chicken breast (31g each)
- 5 x 100g lean ground beef (26g each)

- 4 oz macadamia nuts (21g each)
- 6 tbsp coconut oil (14g each)
These are rough equivalents. Most meals contain a mix of all three macros. Use a food tracking app for precise logging.
These numbers use an estimated 18% body fat.

Frequently Asked Questions
How do I split 135g of protein across meals?
Across 3 meals, each meal needs about 45g of protein. Across 5 meals or snacks, each needs about 27g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 45g per meal in 3 meals is within the optimal 30-40g range.
What are 235g of carbs used for in a cutting diet?
The 235g of carbs provides 940 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. On a cut, carbs fill the remaining calories after protein and fat. At 235g, this is a moderate-carb cut, not a low-carb diet.
Should I recalculate my macros as I lose weight?
Yes. Recalculate every 10-15 lbs of weight loss. As your weight changes, lean mass, BMR, and TDEE all shift. For a 140 lb man cutting to 125 lbs, the TDEE shifts by roughly 230 calories and macros should be recalculated.
What foods hit 135g protein, 88g fat, and 235g carbs?
Protein sources for 135g: roughly 4 x 100g portions of chicken breast (31g protein each), or 23 eggs (6g each), combined with Greek yogurt or protein powder. Fat sources for 88g: about 6 tablespoons of olive oil or peanut butter. Carb sources for 235g: roughly 5 cups of cooked rice (45g each) or 9 cups of oats (27g each). A food tracking app is the most accurate way to hit these targets.
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 1.9x 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.
