Bulking at 230 lb as a moderately active female on the Aggressive (15%) surplus means 3,670 cal daily: 180g protein, 508g carbs, 102g fat. The 478 cal over your 3,192 TDEE is calibrated for about 1.0 lbs per week of gain, which at your 173 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 | 230 lbs |
|---|---|
| Estimated Lean Mass | 173 lbs (75% of body weight) |
| Lean Mass (kg) | 78.2 kg |
| BMR (Katch-McArdle) | 2,059 cal/day |
| TDEE (BMR x 1.55) | 3,192 cal/day |
| Target Calories | 3,670 cal/day |
| Daily Surplus | 478 cal/day (10% surplus) |
| Expected Weekly Change | 0.96 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 1.55 = moderate exercise 3-5 days per week.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 180g | 720 | 20% |
| Carbohydrates | 508g | 2032 | 55% |
| Fat | 102g | 918 | 25% |
| Total | - | 3,670 | 100% |
Protein is set at 2.3g per kg of lean body mass (173 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 3670 cal precisely.
Plan 3 meals that total 3670 calories
Divide daily calories evenly: roughly 1223 cal per meal for a 230 lb woman. Each meal targets about 60g protein, 169g carbs, and 34g fat.
Hit 180g protein first
Protein is the lock, carbs and fat are the flex. 180g across 3 meals is 60g 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 127g of your 508g carbs in the meal 1-2 hours pre-workout and 152g 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 45g protein is easier to hit than 3 larger ones. At 3670 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 230 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 230 lb woman. Load 127g of your 508g daily carbs 2 hours pre-workout for glycogen and stable intra-workout blood sugar. Post-workout, 152g of carbs with 40g protein opens the recovery window. On a bulk at 3670 cal (478 over your 3192 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 2.3 lbs for a 230 lb woman) stacks fat faster than muscle. Second, under-eating protein on high-calorie days: hitting 3670 cal (478 over TDEE) with pasta and ice cream is easy, hitting 180g 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 moderately active activity turn into year-round fat gain.
Frequently Asked Questions
How do I split 180g of protein across meals?
Across 3 meals, each meal needs about 60g of protein. Across 5 meals or snacks, each needs about 36g. Research shows protein synthesis is maximized with 30-40g per meal for most people. 60g per meal in 3 meals is within the optimal 30-40g range.
What are 508g of carbs used for in a bulking diet?
The 508g of carbs provides 2032 calories for workouts and brain function. Carbohydrates replenish muscle glycogen after training, supporting performance and recovery. On a bulk, 508g of carbs drives the calorie surplus needed for muscle growth. Rice, oats, and potatoes are the most efficient sources.
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 230 lb woman bulking to 245 lbs, the TDEE shifts by roughly 170 calories and macros should be recalculated.
What foods hit 180g protein, 102g fat, and 508g carbs?
Protein sources for 180g: roughly 6 x 100g portions of chicken breast (31g protein each), or 30 eggs (6g each), combined with Greek yogurt or protein powder. Fat sources for 102g: about 7 tablespoons of olive oil or peanut butter. Carb sources for 508g: 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 3670 calorie target?
Your Moderately Active activity level uses a multiplier of 1.55, giving a TDEE of 3192 calories. If you were sedentary (1.2x), your TDEE would be approximately 2471 calories. If you were very active (1.725x), it would be approximately 3552 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 3670 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 moderately active activity.
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 1.55x 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.
