A 150 lb lightly active female maintains current weight on 2,024 calories a day, matched exactly to a 2,023 TDEE. Protein at 117g protects the 113 lbs of lean mass that drive your metabolism, while 263g of carbs support energy demand and 56g 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 150 lb body weight while optimizing protein for muscle retention.
How These Macros Were Calculated
| Body Weight | 150 lbs |
|---|---|
| Estimated Lean Mass | 113 lbs (75% of body weight) |
| Lean Mass (kg) | 51 kg |
| BMR (Katch-McArdle) | 1,472 cal/day |
| TDEE (BMR x 1.375) | 2,023 cal/day |
| Target Calories | 2,024 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 1.375 = light exercise 1-3 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 | 117g | 468 | 23% |
| Carbohydrates | 263g | 1052 | 52% |
| Fat | 56g | 504 | 25% |
| Total | - | 2,024 | 100% |
Protein is set at 2.3g per kg of lean body mass (113 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 2024 cal precisely.
Plan 3 meals that total 2024 calories
Divide daily calories evenly: roughly 675 cal per meal for a 150 lb woman. Each meal targets about 39g protein, 88g carbs, and 19g fat.
Hit 117g protein first
Protein is the lock, carbs and fat are the flex. 117g across 3 meals is 39g 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 66g of your 263g carbs in the meal 1-2 hours pre-workout and 79g 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 150 lb woman holding 2024 cal can skip breakfast and eat two larger meals, or spread across 5 smaller ones. What matters is hitting 117g 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 150 lb woman, train to preserve or slowly build lean mass. Pre-workout, 66g of your 263g daily carbs 60 to 90 min before lifting supports performance. Post-workout, 79g 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 117g protein target from becoming wasted at 2024 cal. Without resistance training, the body has no reason to preserve the lean mass these macros are built to protect, and your 2023 TDEE will drift down within a year.
Common pitfalls to avoid
At maintenance for a 150 lb woman on 2024 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 8 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 150 lb set point. Second pitfall: dropping training once calorie pressure is off. Without progressive resistance training, muscle mass slowly declines, which lowers your 2023 TDEE, which turns 2024 into 1924+ effective cal within a year. Lift 3 times a week minimum at 117g protein daily.
Frequently Asked Questions
How does my activity level affect my 2024 calorie target?
Your Lightly Active activity level uses a multiplier of 1.375, giving a TDEE of 2023 calories. If you were sedentary (1.2x), your TDEE would be approximately 1766 calories. If you were very active (1.725x), it would be approximately 2539 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 maintaining weight at 2024 calories?
If your weight trends up or down consistently over 2 weeks at 2024 calories, your actual TDEE differs from the estimate. Adjust by 100 calories in the direction that corrects the trend. Recalculate every time you change activity level significantly.
How long should I stay in a maintenance phase at 2024 calories?
Maintenance phases should last 4-8 weeks between a cut and a bulk. They reset hunger hormones, establish a new weight set point, and give your body a break from the stress of a deficit or surplus.
Should I eat more on training days at 2024 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 202 calories on training days and subtract 202 on rest days. Your weekly calorie total stays fixed.
Is 2024 calories per day too fixed for a 150 lb female?
2024 matches a 2023 TDEE almost exactly. For a 150 lb woman at lightly 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 117g of protein across the day for muscle protein synthesis?
Research on muscle protein synthesis (MPS) shows a leucine threshold of roughly 2.5-3g per meal, which corresponds to about 25-40g of high-quality protein. For 117g total, 4 meals of 30g each fully saturates MPS at each feeding. Spacing protein feedings 3-5 hours apart keeps synthesis elevated through the day. A pre-sleep dose of 30-40g casein or Greek yogurt further extends overnight synthesis by 20-30%, which is especially valuable during maintenance recomposition.
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 1.375x estimate for lightly 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 150 lbs.
