Macros for 140 lb Women (Bulking, Sedentary)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 140 lb woman on a bulking 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 | 105 lbs (75% of body weight) |
| Lean Mass (kg) | 47.6 kg |
| BMR (Katch-McArdle) | 1,398 cal/day |
| TDEE (BMR x 1.2) | 1,678 cal/day |
| Target Calories | 1,846 cal/day |
| Daily Surplus | 168 cal/day (10% surplus) |
| Expected Weekly Change | 0.34 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 25% average body fat for women. Activity multiplier 1.2 = desk job, little or no exercise.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 109g | 436 | 24% |
| Carbohydrates | 213g | 852 | 46% |
| Fat | 62g | 558 | 30% |
| Total | - | 1,846 | 100% |
Protein is set at 2.3g per kg of lean body mass (105 lbs lean mass for this woman). 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
Should I recalculate my macros as I gain weight?
Yes. Recalculate every 10-15 lbs of weight gain. As your weight changes, lean mass, BMR, and TDEE all shift. For a 140 lb woman bulking to 155 lbs, the TDEE shifts by roughly 132 calories and macros should be recalculated.
What foods hit 109g protein, 62g fat, and 213g carbs?
Protein sources for 109g: roughly 4 x 100g portions of chicken breast (31g protein each), or 18 eggs (6g each), combined with Greek yogurt or protein powder. Fat sources for 62g: about 4 tablespoons of olive oil or peanut butter. Carb sources for 213g: roughly 5 cups of cooked rice (45g each) or 8 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 1846 calorie target?
Your Sedentary activity level uses a multiplier of 1.2, giving a TDEE of 1678 calories. If you were sedentary (1.2x), your TDEE would be approximately 1678 calories. If you were very active (1.725x), it would be approximately 2412 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 gaining weight at 1846 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 sedentary activity.
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 1.2x 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.
