A 170 lb very active female on a Normal (10%) bulking surplus needs about 3,073 calories a day to add lean muscle without drifting into soft gains. That is a 281 calorie surplus over a 2,792 TDEE, projecting roughly 0.6 lbs of weight gain per week. Protein sits at 133g to keep nitrogen balance positive, 444g of carbs fuel lift volume, and 85g 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 1.725) | 2,792 cal/day |
| Target Calories | 3,073 cal/day |
| Daily Surplus | 281 cal/day (10% surplus) |
| Expected Weekly Change | 0.56 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 1.725 = hard exercise 6-7 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 133g | 532 | 17% |
| Carbohydrates | 444g | 1776 | 58% |
| Fat | 85g | 765 | 25% |
| Total | - | 3,073 | 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 3073 cal precisely.
Plan 3 meals that total 3073 calories
Divide daily calories evenly: roughly 1024 cal per meal for a 170 lb woman. Each meal targets about 44g protein, 148g carbs, and 28g 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 111g of your 444g carbs in the meal 1-2 hours pre-workout and 133g 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 3073 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 111g of your 444g daily carbs 2 hours pre-workout for glycogen and stable intra-workout blood sugar. Post-workout, 133g of carbs with 40g protein opens the recovery window. On a bulk at 3073 cal (281 over your 2792 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 3073 cal (281 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 very active activity turn into year-round fat gain.
Frequently Asked Questions
How were the macros calculated for a 170 lb female?
The calculation uses the Katch-McArdle BMR formula. A 170 lb woman with an estimated 75% lean mass (128 lbs lean) has a BMR of 1618 calories. Multiplied by 1.725 for very active activity (Hard exercise 6-7 days per week), the TDEE is 2792 calories per day. For bulking at the Normal (10%) level, the surplus brings the target to 3073 calories.
Why is protein 133g for bulking at 170 lbs?
Protein for bulking at the Normal (10%) level is set at 2.3g per kg of lean body mass. A 170 lb woman with 128 lbs of lean mass needs 133g of protein per day. During a bulk, 2.3g per kg of lean mass supports muscle protein synthesis without excess calories from protein.
How much weight will I gain at 3073 calories?
At 3073 calories per day, a 170 lb woman should gain approximately 0.56 lbs per week. This assumes a TDEE of 2792 at very active activity and a surplus of 281 calories per day. Results vary based on actual metabolic rate, training load, and adherence.
Why is fat set at 85g for a bulking diet?
Fat is set at 25% of total calories, which is 765 calories or 85g per day. Fat is essential for hormone production, fat-soluble vitamin absorption, and satiety. Bulking and maintenance use 25% fat for steady hormonal support. A unisex floor of max(0.5g per kg body weight, 20% of calories) protects testosterone and estrogen below the percentage target.
How do I split 133g of protein across meals?
Across 3 meals, each meal needs about 44g of protein. Across 5 meals or snacks, each needs about 27g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 44g per meal in 3 meals is within the optimal 30-40g range.
What are 444g of carbs used for in a bulking diet?
The 444g of carbs provides 1776 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. On a bulk, 444g 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.
