A 180 lb moderately active female maintains current weight on 2,621 calories a day, matched exactly to a 2,622 TDEE. Protein at 141g protects the 135 lbs of lean mass that drive your metabolism, while 350g of carbs support energy demand and 73g of fat covers hormonal baseline. Maintenance is not passive, it is calibration. Body weight should drift within about 1.5 lbs over any four-week window. If the scale climbs outside that band, trim 150 cal. If it drops, add 150. This is also the setup for slow recomposition: lean mass up, body fat down, body weight flat, driven by training quality rather than calorie cuts.

Eating at TDEE with zero deficit or surplus. These macros maintain your 180 lb body weight while optimizing protein for muscle retention.
How These Macros Were Calculated
| Body Weight | 180 lbs |
|---|---|
| Estimated Lean Mass | 135 lbs (75% of body weight) |
| Lean Mass (kg) | 61.2 kg |
| BMR (Katch-McArdle) | 1,692 cal/day |
| TDEE (BMR x 1.55) | 2,622 cal/day |
| Target Calories | 2,621 cal/day |
| Calorie Change | None (maintenance) |
| Expected Weekly Change | Stable weight |
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. These static macro guide pages use one combined activity level for readable comparisons. The interactive macro calculator separates daily movement from training for a more precise target.
Macro Breakdown
| Macro | Grams | Calories | % of Total |
|---|---|---|---|
| Protein | 141g | 564 | 22% |
| Carbohydrates | 350g | 1400 | 53% |
| Fat | 73g | 657 | 25% |
| Total | - | 2,621 | 100% |
Protein is set at 2.3g per kg of lean body mass (135 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 2621 cal precisely.
Plan 3 meals that total 2621 calories
Divide daily calories evenly: roughly 874 cal per meal for a 180 lb woman. Each meal targets about 47g protein, 117g carbs, and 24g fat.
Hit 141g protein first
Protein is the lock, carbs and fat are the flex. 141g across 3 meals is 47g 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 88g of your 350g carbs in the meal 1-2 hours pre-workout and 105g in the post-workout meal. Spread fat evenly across remaining meals. Carb timing matters for training quality on a target.
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 the weekly average drifts more than 1.5 lbs in either direction, adjust 100 cal opposite the drift. Never adjust on a single day's reading.
What This Looks Like In Practice
Meal timing and structure
At maintenance, meal timing is flexible because total calories are the main lever. 3 to 4 meals works for most schedules. A 180 lb woman holding 2621 cal can skip breakfast and eat two larger meals, or spread across 5 smaller ones. What matters is hitting 141g of protein total and staying within ±100 cal of target on a weekly average. Consistency at the week level beats precision at the meal level.
Training day nutrition
At maintenance for a 180 lb woman, train to preserve or slowly build lean mass. Pre-workout, 88g of your 350g daily carbs 60 to 90 min before lifting supports performance. Post-workout, 105g of carbs plus 30g to 40g protein replenishes glycogen and triggers synthesis. Lifting 3 to 4 times per week with progressive overload is what keeps the 141g protein target from becoming wasted at 2621 cal. Without resistance training, the body has no reason to preserve the lean mass these macros are built to protect, and your 2622 TDEE will drift down within a year.
Common pitfalls to avoid
At maintenance for a 180 lb woman on 2621 cal, the biggest pitfall is drift. Weight creeps up 2 to 3 lbs over a month, scale moves feel noisy, and six months later the baseline is 9 lbs heavier. Fix this with a weekly average: step on the scale 5 mornings a week, take the 7-day average, compare week-over-week against your 180 lb set point. Second pitfall: dropping training once calorie pressure is off. Without progressive resistance training, muscle mass slowly declines, which lowers your 2622 TDEE, which turns 2621 into 2521+ effective cal within a year. Lift 3 times a week minimum at 141g protein daily.
Frequently Asked Questions
Should I eat more on training days at 2621 calories?
Calorie cycling is not necessary for most people. Consistent daily targets outperform complex cycling protocols. If you want to try it, shift 10-15% of calories from rest days to training days while keeping the weekly total at 18347 calories.
Is 2621 calories per day too fixed for a 180 lb female?
2621 matches a 2622 TDEE almost exactly. For a 180 lb woman at moderately active activity, this is the calibration where body weight holds steady on a weekly average. Daily scale moves of 1-3 lbs are water and gut content, not fat. If the 7-day average trends in either direction for 3 weeks, adjust by 100 cal in the opposite direction.
How should I distribute 141g of protein across the day for muscle protein synthesis?
Spread 141g across 5 meals of roughly 30g each, spaced 3-5 hours apart. Each meal hits the leucine threshold needed to trigger muscle protein synthesis. A 30-40g casein or Greek yogurt dose before sleep extends overnight synthesis — especially valuable during recomposition.
Can I swap carbs for fat or vice versa within my 2621 calorie target?
Yes. Keep protein fixed at 141g and swap carbs and fat freely — 10g of fat trades for ~23g of carbs. Two floors: fat above 58g (20% of calories) and carbs above 50g. Hit protein, land at 2621 calories, and the carb-fat split is yours.
Should I drink my calories or eat them at 180 lbs?
Mix both. At maintenance, there is no forcing function. Whole foods deliver micronutrients and fiber that liquid calories skip. A protein shake post-workout plus 3-4 solid meals is the cleanest split. If you enjoy a daily smoothie or latte, count the calories against 2621 and move on. Alcohol is the single biggest blind spot, 150-300 cal per drink with zero satiety.
How were the macros calculated for a 180 lb female?
The calculation uses the Katch-McArdle BMR formula. A 180 lb woman with an estimated 75% lean mass (135 lbs lean) has a BMR of 1692 calories. Multiplied by 1.55 for moderately active activity (Moderate exercise 3-5 days per week), the TDEE is 2622 calories per day. For maintenance, the target matches TDEE at 2621 calories.
When to Recalculate These Macros
Weight trending upward over 2 weeks
Reduce by 100-150 cal/day from carbs. Your actual TDEE is slightly below the 1.55x estimate for moderately active activity.
Weight trending downward over 2 weeks
Add 100-150 cal/day from carbs or fat. You may be more active than the multiplier accounts for, or your metabolism has adapted upward.
Activity level has changed significantly
Switch to the matching activity level using the selector above. The difference between sedentary and moderately active can be 300-500 cal/day at 180 lbs.
