Macros for 140 lb Women (Bulking, Lightly 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 lightly active TDEE (light exercise 1-3 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 1.375) | 1,922 cal/day |
| Target Calories | 2,114 cal/day |
| Daily Surplus | 192 cal/day (10% surplus) |
| Expected Weekly Change | 0.38 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 | 109g | 436 | 21% |
| Carbohydrates | 262g | 1048 | 49% |
| Fat | 70g | 630 | 30% |
| Total | - | 2,114 | 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 eat more on training days at 2114 calories?
Cycling calories is not necessary for most people. Hitting your daily target consistently produces better results than complex cycling protocols. If you want to cycle, shift 10-15% of daily calories from rest days to training days while keeping the weekly total the same. For example, add 211 calories on training days and subtract 211 on rest days. Your weekly calorie total stays fixed.
How were the macros calculated for a 140 lb female?
The calculation uses the Katch-McArdle BMR formula. A 140 lb woman with an estimated 75% lean mass (105 lbs lean) has a BMR of 1398 calories. Multiplied by 1.375 for lightly active activity (Light exercise 1-3 days per week), the TDEE is 1922 calories per day. For bulking, a 10% surplus brings the target to 2114 calories.
Why is protein 109g for bulking at 140 lbs?
Protein for bulking is set at 2.3g per kg of lean body mass. A 140 lb woman with 105 lbs of lean mass needs 109g 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 2114 calories?
At 2114 calories per day, a 140 lb woman should gain approximately 0.38 lbs per week. This assumes a TDEE of 1922 at lightly active activity and a surplus of 192 calories per day. Results vary based on actual metabolic rate, training load, and adherence.
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.
