Macros for 140 lb Men (Maintenance, Lightly Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 140 lb man on a maintenance diet. Calculated from estimated lean mass, Katch-McArdle BMR, and a lightly active TDEE (light exercise 1-3 days per week).

Eating at TDEE with zero deficit or surplus. These macros maintain your 140 lb body weight while optimizing protein for muscle retention.
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 1.375) | 2,056 cal/day |
| Target Calories | 2,057 cal/day |
| Calorie Change | None (maintenance) |
| Expected Weekly Change | Stable weight |
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 1.375 = light exercise 1-3 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 120g | 480 | 23% |
| Carbohydrates | 239g | 956 | 47% |
| Fat | 69g | 621 | 30% |
| Total | - | 2,057 | 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.

Research shows muscle protein synthesis is maximized with 30-40g protein per meal. 40g per meal in 3 meals is within the optimal range.

Frequently Asked Questions
What foods hit 120g protein, 69g fat, and 239g carbs?
Protein sources for 120g: roughly 4 x 100g portions of chicken breast (31g protein each), or 20 eggs (6g each), combined with Greek yogurt or protein powder. Fat sources for 69g: about 5 tablespoons of olive oil or peanut butter. Carb sources for 239g: 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.
How does my activity level affect my 2057 calorie target?
Your Lightly Active activity level uses a multiplier of 1.375, giving a TDEE of 2056 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 maintaining weight at 2057 calories?
If your weight trends up or down consistently over 2 weeks at 2057 calories, your actual TDEE differs from the estimate. Adjust by 100 calories in the direction that corrects the trend. Recalculate every time you change activity level significantly.
How long should I stay in a maintenance phase at 2057 calories?
Maintenance phases should last 4-8 weeks between a cut and a bulk. They reset hunger hormones, establish a new weight set point, and give your body a break from the stress of a deficit or surplus.
When to Recalculate These Macros
Weight trending upward over 2 weeks
Reduce by 100-150 cal/day from carbs. Your actual TDEE is slightly below the 1.375x estimate for lightly active activity.
Weight trending downward over 2 weeks
Add 100-150 cal/day from carbs or fat. You may be more active than the multiplier accounts for, or your metabolism has adapted upward.
Activity level has changed significantly
Switch to the matching activity level using the selector above. The difference between sedentary and moderately active can be 300-500 cal/day at 140 lbs.
