Macros for 140 lb Women (Bulking, Moderately Active)
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 moderately active TDEE (moderate exercise 3-5 days per week).

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 1.55) | 2,167 cal/day |
| Target Calories | 2,383 cal/day |
| Daily Surplus | 216 cal/day (10% surplus) |
| Expected Weekly Change | 0.43 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 1.55 = moderate exercise 3-5 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 109g | 436 | 18% |
| Carbohydrates | 309g | 1236 | 52% |
| Fat | 79g | 711 | 30% |
| Total | - | 2,383 | 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
How do I split 109g of protein across meals?
Across 3 meals, each meal needs about 36g of protein. Across 5 meals or snacks, each needs about 22g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 36g per meal in 3 meals is within the optimal 30-40g range.
What are 309g of carbs used for in a bulking diet?
The 309g of carbs provides 1236 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. On a bulk, 309g of carbs drives the calorie surplus needed for muscle growth. Rice, oats, and potatoes are the most efficient sources.
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 171 calories and macros should be recalculated.
What foods hit 109g protein, 79g fat, and 309g 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 79g: about 6 tablespoons of olive oil or peanut butter. Carb sources for 309g: roughly 7 cups of cooked rice (45g each) or 11 cups of oats (27g each). A food tracking app is the most accurate way to hit these targets.
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.
