A 180 lb lightly active male on a Lean Gain (5%) bulking surplus needs about 2,621 calories a day to add lean muscle without drifting into soft gains. That is a 125 calorie surplus over a 2,496 TDEE, projecting roughly 0.3 lbs of weight gain per week. Protein sits at 154g to keep nitrogen balance positive, 337g of carbs fuel lift volume, and 73g of fat covers hormonal baseline. The 148 lbs of lean mass is what sets your BMR, which is why bulking on muscle beats bulking on fat long term. Track weekly weigh-ins. If the scale climbs faster than 2 lbs a week for three weeks, trim 150 cal. If it stalls flat for three, add 150.

How These Macros Were Calculated
| Body Weight | 180 lbs |
|---|---|
| Estimated Lean Mass | 148 lbs (82% of body weight) |
| Lean Mass (kg) | 66.9 kg |
| BMR (Katch-McArdle) | 1,815 cal/day |
| TDEE (BMR x 1.375) | 2,496 cal/day |
| Target Calories | 2,621 cal/day |
| Daily Surplus | 125 cal/day (10% surplus) |
| Expected Weekly Change | 0.25 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 1.375 = light exercise 1-3 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 154g | 616 | 24% |
| Carbohydrates | 337g | 1348 | 51% |
| Fat | 73g | 657 | 25% |
| Total | - | 2,621 | 100% |
Protein is set at 2.3g per kg of lean body mass (148 lbs lean mass for this man). Fat targets 25% of target calories with a unisex floor of max(0.5g per kg body weight, 20% of calories) applied if the percentage drops below it. Carbs fill the remaining calories, with a 50g minimum for brain function.

How to Hit These Macros Daily
Buy a digital food scale
A food scale eliminates the single biggest source of calorie miscalculation: eyeballed portions. A $15 scale pays for itself the first week by surfacing hidden 200 to 400 cal overshoots. Required for hitting 2621 cal precisely.
Plan 3 meals that total 2621 calories
Divide daily calories evenly: roughly 874 cal per meal for a 180 lb man. Each meal targets about 51g protein, 112g carbs, and 24g fat.
Hit 154g protein first
Protein is the lock, carbs and fat are the flex. 154g across 3 meals is 51g each. Pick one anchor protein source per meal (chicken, beef, fish, Greek yogurt, eggs) and portion it before adding anything else. If you fall short on calories by bedtime, top up with carbs or fat, not extra protein.
Split carbs and fat around training
Put 84g of your 337g carbs in the meal 1-2 hours pre-workout and 101g in the post-workout meal. Spread fat evenly across remaining meals. Carb timing matters for training quality on a surplus.
Track every input for 14 days
Log every meal, snack, drink, and cooking oil for 14 days using any tracking app. No eyeballing. The calibration period surfaces blind spots: dressings, condiments, weekend drift. After 14 days, tracking becomes automatic.
Adjust by 100 cal weekly based on the scale trend
Step on the scale 5 mornings a week, average the readings. Compare to last week. If weight has not moved up in 2 weeks, add 100 cal to carbs. Gaining more than 0.75 lbs/week? Cut 100 cal. Never adjust on a single day's reading.
What This Looks Like In Practice
Meal timing and structure
On a bulk, 4 to 5 meals of 39g protein is easier to hit than 3 larger ones. At 2621 cal, a 3-meal structure forces 800 to 1,200 cal per sitting, which most people struggle with. Spread the load. Breakfast, mid-morning, post-workout, dinner, pre-sleep is a common template for a 180 lb man. The pre-sleep meal (30g casein or Greek yogurt) supports overnight muscle protein synthesis and adds 200 to 300 cal without fighting appetite during the day.
Training day nutrition
Training days drive the surplus for a 180 lb man. Load 84g of your 337g daily carbs 2 hours pre-workout for glycogen and stable intra-workout blood sugar. Post-workout, 101g of carbs with 40g protein opens the recovery window. On a bulk at 2621 cal (125 over your 2496 TDEE), training intensity is the signal that your surplus is calibrated right: if main lifts stall for 2 to 3 weeks, the surplus is too small, not the volume. The bar moves when the calories are there.
Common pitfalls to avoid
Most bulks fail three ways. First, going too fast: gaining more than 1% of body weight per week (more than 1.8 lbs for a 180 lb man) stacks fat faster than muscle. Second, under-eating protein on high-calorie days: hitting 2621 cal (125 over TDEE) with pasta and ice cream is easy, hitting 154g protein is the discipline. Third, never leaving the bulk: after 12 to 20 weeks, shift to maintenance for 6 to 8 weeks or start a mini-cut. Year-round bulks at lightly active activity turn into year-round fat gain.
Frequently Asked Questions
Is 2621 calories per day too high for a 180 lb male?
2621 is a 5% surplus (Lean Gain) over a 2496 TDEE. Andrew Menechian's framework caps the slider at 15% Aggressive because larger surpluses convert to fat faster than muscle. At 125 extra per day, weight should climb about 0.25 lbs per week, biased toward lean tissue rather than fat for a 180 lb man. If the scale moves faster than 0.75% of body weight per week, drop 100 cal or step back to a smaller surplus level.
How should I distribute 154g of protein across the day for muscle protein synthesis?
Research on muscle protein synthesis (MPS) shows a leucine threshold of roughly 2.5-3g per meal, which corresponds to about 25-40g of high-quality protein. For 154g total, 5 meals of 30g each fully saturates MPS at each feeding. Spacing protein feedings 3-5 hours apart keeps synthesis elevated through the day. A pre-sleep dose of 30-40g casein or Greek yogurt further extends overnight synthesis by 20-30%, which is especially valuable during a bulk when recovery drives muscle gain.
Can I swap carbs for fat or vice versa within my 2621 calorie target?
Yes, within limits. Keep protein fixed at 154g and swap carbs and fat based on preference and training. Each gram of fat is 9 cal, each gram of carbs is 4 cal, so 10g of fat swaps for about 23g of carbs. The floor is fat not dropping below 20% of total calories (58g) to protect hormones, and carbs staying above 50g for brain and glycogen function. Within those bounds, a higher-fat day and a higher-carb day both work, as long as protein is hit and total calories land at 2621.
Should I drink my calories or eat them at 180 lbs?
Liquid calories are the bulking shortcut when appetite caps out. A 600 cal mass gainer shake or a 700 cal oats-and-peanut-butter smoothie can close the gap on a 2621 cal target when solid meals become a chore. Drink them between meals, not with them. Keep the shake heavy on protein (30g+) and real carb sources (oats, rice milk) rather than sugar.
How were the macros calculated for a 180 lb male?
The calculation uses the Katch-McArdle BMR formula. A 180 lb man with an estimated 82% lean mass (148 lbs lean) has a BMR of 1815 calories. Multiplied by 1.375 for lightly active activity (Light exercise 1-3 days per week), the TDEE is 2496 calories per day. For bulking at the Lean Gain (5%) level, the surplus brings the target to 2621 calories.
Why is protein 154g for bulking at 180 lbs?
Protein for bulking at the Lean Gain (5%) level is set at 2.3g per kg of lean body mass. A 180 lb man with 148 lbs of lean mass needs 154g of protein per day. During a bulk, 2.3g per kg of lean mass supports muscle protein synthesis without excess calories from protein.
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.
