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 1.725) | 2,579 cal/day |
| Target Calories | 2,839 cal/day |
| Daily Surplus | 260 cal/day (10% surplus) |
| Expected Weekly Change | 0.52 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 18% average body fat for men. Activity multiplier 1.725 = hard exercise 6-7 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 120g | 480 | 17% |
| Carbohydrates | 376g | 1504 | 53% |
| Fat | 95g | 855 | 30% |
| Total | - | 2,839 | 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.

Frequently Asked Questions
How much weight will I gain at 2839 calories?
At 2839 calories per day, a 140 lb man should gain approximately 0.52 lbs per week. This assumes a TDEE of 2579 at very active activity and a surplus of 260 calories per day. Results vary based on actual metabolic rate, training load, and adherence.
Why is fat set at 95g for a bulking diet?
Fat is set at 30% of total calories, which is 855 calories or 95g 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 120g of protein across meals?
Across 3 meals, each meal needs about 40g of protein. Across 5 meals or snacks, each needs about 24g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 40g per meal in 3 meals is within the optimal 30-40g range.
What are 376g of carbs used for in a bulking diet?
The 376g of carbs provides 1504 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. On a bulk, 376g of carbs drives the calorie surplus needed for muscle growth. Rice, oats, and potatoes are the most efficient sources.
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 1.725x 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.
