Bulking at 170 lb as a lightly active male on the Aggressive (15%) surplus means 2,744 cal daily: 145g protein, 370g carbs, 76g fat. The 358 cal over your 2,386 TDEE is calibrated for about 0.7 lbs per week of gain, which at your 139 lbs lean mass ratio biases toward muscle rather than fat. Keep protein fixed. Let carbs float higher on training days, lower on rest. Expect some fat gain, it is the cost of meaningful muscle accrual. The real signal is the barbell: if main lifts are not moving up about 2 lbs every 2 to 3 weeks, your surplus is too small, not too big. Measure gains at the bar first, the scale second.

How These Macros Were Calculated
| Body Weight | 170 lbs |
|---|---|
| Estimated Lean Mass | 139 lbs (82% of body weight) |
| Lean Mass (kg) | 63.2 kg |
| BMR (Katch-McArdle) | 1,735 cal/day |
| TDEE (BMR x 1.375) | 2,386 cal/day |
| Target Calories | 2,744 cal/day |
| Daily Surplus | 358 cal/day (10% surplus) |
| Expected Weekly Change | 0.72 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 | 145g | 580 | 21% |
| Carbohydrates | 370g | 1480 | 54% |
| Fat | 76g | 684 | 25% |
| Total | - | 2,744 | 100% |
Protein is set at 2.3g per kg of lean body mass (139 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 2744 cal precisely.
Plan 3 meals that total 2744 calories
Divide daily calories evenly: roughly 915 cal per meal for a 170 lb man. Each meal targets about 48g protein, 123g carbs, and 25g fat.
Hit 145g protein first
Protein is the lock, carbs and fat are the flex. 145g across 3 meals is 48g 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 93g of your 370g carbs in the meal 1-2 hours pre-workout and 111g 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 36g protein is easier to hit than 3 larger ones. At 2744 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 170 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 170 lb man. Load 93g of your 370g daily carbs 2 hours pre-workout for glycogen and stable intra-workout blood sugar. Post-workout, 111g of carbs with 40g protein opens the recovery window. On a bulk at 2744 cal (358 over your 2386 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 1.7 lbs for a 170 lb man) stacks fat faster than muscle. Second, under-eating protein on high-calorie days: hitting 2744 cal (358 over TDEE) with pasta and ice cream is easy, hitting 145g 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 2744 calories per day too high for a 170 lb male?
2744 is a 15% surplus (Aggressive) over a 2386 TDEE. Andrew Menechian's framework caps the slider at 15% Aggressive because larger surpluses convert to fat faster than muscle. At 358 extra per day, weight should climb about 0.72 lbs per week, biased toward lean tissue rather than fat for a 170 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 145g 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 145g 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 2744 calorie target?
Yes, within limits. Keep protein fixed at 145g 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 (61g) 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 2744.
Should I drink my calories or eat them at 170 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 2744 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 170 lb male?
The calculation uses the Katch-McArdle BMR formula. A 170 lb man with an estimated 82% lean mass (139 lbs lean) has a BMR of 1735 calories. Multiplied by 1.375 for lightly active activity (Light exercise 1-3 days per week), the TDEE is 2386 calories per day. For bulking at the Aggressive (15%) level, the surplus brings the target to 2744 calories.
Why is protein 145g for bulking at 170 lbs?
Protein for bulking at the Aggressive (15%) level is set at 2.3g per kg of lean body mass. A 170 lb man with 139 lbs of lean mass needs 145g 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.
