PN1, PNC 1&2, Poliquin PICP 1&2 · Updated April 2026
A 170 lb lightly active female on a Normal (10%) bulking surplus needs about 2,448 calories a day to add lean muscle without drifting into soft gains. That is a 223 calorie surplus over a 2,225 TDEE, projecting roughly 0.5 lbs of weight gain per week. Protein sits at 133g to keep nitrogen balance positive, 326g of carbs fuel lift volume, and 68g of fat covers hormonal baseline. The 128 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 | 170 lbs |
|---|---|
| Estimated Lean Mass | 128 lbs (75% of body weight) |
| Lean Mass (kg) | 57.8 kg |
| BMR (Katch-McArdle) | 1,618 cal/day |
| TDEE (BMR x 1.375) | 2,225 cal/day |
| Target Calories | 2,448 cal/day |
| Daily Surplus | 223 cal/day (10% surplus) |
| Expected Weekly Change | 0.45 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 | 133g | 532 | 22% |
| Carbohydrates | 326g | 1304 | 53% |
| Fat | 68g | 612 | 25% |
| Total | - | 2,448 | 100% |
Protein is set at 2.3g per kg of lean body mass (128 lbs lean mass for this woman). 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 2448 cal precisely.
Plan 3 meals that total 2448 calories
Divide daily calories evenly: roughly 816 cal per meal for a 170 lb woman. Each meal targets about 44g protein, 109g carbs, and 23g fat.
Hit 133g protein first
Protein is the lock, carbs and fat are the flex. 133g across 3 meals is 44g 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 82g of your 326g carbs in the meal 1-2 hours pre-workout and 98g 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 33g protein is easier to hit than 3 larger ones. At 2448 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 woman. 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 woman. Load 82g of your 326g daily carbs 2 hours pre-workout for glycogen and stable intra-workout blood sugar. Post-workout, 98g of carbs with 40g protein opens the recovery window. On a bulk at 2448 cal (223 over your 2225 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 woman) stacks fat faster than muscle. Second, under-eating protein on high-calorie days: hitting 2448 cal (223 over TDEE) with pasta and ice cream is easy, hitting 133g 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
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 woman bulking to 185 lbs, the TDEE shifts by roughly 152 calories and macros should be recalculated.
What foods hit 133g protein, 68g fat, and 326g carbs?
Protein sources for 133g: roughly 4 x 100g portions of chicken breast (31g protein each), or 22 eggs (6g each), combined with Greek yogurt or protein powder. Fat sources for 68g: about 5 tablespoons of olive oil or peanut butter. Carb sources for 326g: roughly 7 cups of cooked rice (45g each) or 12 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 2448 calorie target?
Your Lightly Active activity level uses a multiplier of 1.375, giving a TDEE of 2225 calories. If you were sedentary (1.2x), your TDEE would be approximately 1942 calories. If you were very active (1.725x), it would be approximately 2791 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 2448 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 lightly active activity.
How long should I stay in a bulking phase at 2448 calories?
Lean bulks typically run 12-20 weeks. At 2448 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 2448 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 245 calories on training days and subtract 245 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 1.375x 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.
