Bulking at 170 lb as a very active male on the Aggressive (15%) surplus means 3,444 cal daily: 145g protein, 500g carbs, 96g fat. The 451 cal over your 2,993 TDEE is calibrated for about 0.9 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 1.725) | 2,993 cal/day |
| Target Calories | 3,444 cal/day |
| Daily Surplus | 451 cal/day (10% surplus) |
| Expected Weekly Change | 0.9 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 | 145g | 580 | 17% |
| Carbohydrates | 500g | 2000 | 58% |
| Fat | 96g | 864 | 25% |
| Total | - | 3,444 | 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 3444 cal precisely.
Plan 3 meals that total 3444 calories
Divide daily calories evenly: roughly 1148 cal per meal for a 170 lb man. Each meal targets about 48g protein, 167g carbs, and 32g 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 125g of your 500g carbs in the meal 1-2 hours pre-workout and 150g 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 3444 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 125g of your 500g daily carbs 2 hours pre-workout for glycogen and stable intra-workout blood sugar. Post-workout, 150g of carbs with 40g protein opens the recovery window. On a bulk at 3444 cal (451 over your 2993 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 3444 cal (451 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 very active activity turn into year-round fat gain.
Frequently Asked Questions
Should I recalculate my macros as I gain weight?
Yes. Recalculate every 10-15 lbs of weight gain. As your weight changes, lean mass, BMR, and TDEE all shift. For a 170 lb man bulking to 185 lbs, the TDEE shifts by roughly 209 calories and macros should be recalculated.
What foods hit 145g protein, 96g fat, and 500g carbs?
Protein sources for 145g: roughly 5 x 100g portions of chicken breast (31g protein each), or 24 eggs (6g each), combined with Greek yogurt or protein powder. Fat sources for 96g: about 7 tablespoons of olive oil or peanut butter. Carb sources for 500g: roughly 11 cups of cooked rice (45g each) or 19 cups of oats (27g each). A food tracking app is the most accurate way to hit these targets.
How does my activity level affect my 3444 calorie target?
Your Very Active activity level uses a multiplier of 1.725, giving a TDEE of 2993 calories. If you were sedentary (1.2x), your TDEE would be approximately 2082 calories. If you were very active (1.725x), it would be approximately 2993 calories. The activity multiplier is the single biggest variable in your calorie target. Getting it right matters more than small differences in the macro split.
What should I do if I'm not gaining weight at 3444 calories?
After 2 weeks with no movement, your actual TDEE likely differs from the estimate. Add 100-150 calories, prioritizing carbs. Gaining too fast (more than 1 lb/week)? Cut 100-150 calories. The target assumes very active activity.
How long should I stay in a bulking phase at 3444 calories?
Lean bulks typically run 12-20 weeks. At 3444 calories, expect gradual muscle gain with minimal fat. When body fat feels high (above 18-20% for men, 28-30% for women), transition to maintenance or a cut.
Should I eat more on training days at 3444 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 344 calories on training days and subtract 344 on rest days. Your weekly calorie total stays fixed.
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.
