Macros for 130 lb Women (Bulking, Lightly Active)
Reviewed by Andrew Menechian, Head of Fitness at FitCommit
Exact macros for a 130 lb woman on a bulking diet. Calculated from estimated lean mass, Katch-McArdle BMR, and a lightly active TDEE (light exercise 1-3 days per week).

How These Macros Were Calculated
| Body Weight | 130 lbs |
|---|---|
| Estimated Lean Mass | 98 lbs (75% of body weight) |
| Lean Mass (kg) | 44.2 kg |
| BMR (Katch-McArdle) | 1,325 cal/day |
| TDEE (BMR x 1.375) | 1,821 cal/day |
| Target Calories | 2,003 cal/day |
| Daily Surplus | 182 cal/day (10% surplus) |
| Expected Weekly Change | 0.36 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 1.375 = light exercise 1-3 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 102g | 408 | 20% |
| Carbohydrates | 248g | 992 | 50% |
| Fat | 67g | 603 | 30% |
| Total | - | 2,003 | 100% |
Protein is set at 2.3g per kg of lean body mass (98 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
Why is protein 102g for bulking at 130 lbs?
Protein for bulking is set at 2.3g per kg of lean body mass. A 130 lb woman with 98 lbs of lean mass needs 102g of protein per day. During a bulk, 2.3g per kg of lean mass supports muscle protein synthesis without excess calories from protein.
How much weight will I gain at 2003 calories?
At 2003 calories per day, a 130 lb woman should gain approximately 0.36 lbs per week. This assumes a TDEE of 1821 at lightly active activity and a surplus of 182 calories per day. Results vary based on actual metabolic rate, training load, and adherence.
Why is fat set at 67g for a bulking diet?
Fat is set at 30% of total calories, which is 603 calories or 67g per day. Fat is essential for hormone production, fat-soluble vitamin absorption, and satiety. Keeping fat at 30% of calories maintains hormone function during a calorie surplus. Dropping fat below 20% of total calories can impair testosterone, estrogen, and recovery.
How do I split 102g of protein across meals?
Across 3 meals, each meal needs about 34g of protein. Across 5 meals or snacks, each needs about 20g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 34g per meal in 3 meals is within the optimal 30-40g range.
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 1.375x 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.
