Maintaining 240 lb as a very active female means 3,678 cal daily: 188g protein, 502g carbs, 102g fat. These numbers match your 3,679 TDEE exactly, with protein weighted to hold 180 lbs of lean mass and a minor surplus capacity for muscle repair. Weekly weigh-ins matter more than daily, since food volume and water swings show up as 2 to 3 lbs of scale noise. Maintenance only works long term when paired with progressive resistance training. Without it, the body has no reason to preserve the lean tissue these macros are built to protect. Hit protein every day. Let carbs and fat flex by about 20g as training load varies.

How These Macros Were Calculated
| Body Weight | 240 lbs |
|---|---|
| Estimated Lean Mass | 180 lbs (75% of body weight) |
| Lean Mass (kg) | 81.6 kg |
| BMR (Katch-McArdle) | 2,133 cal/day |
| TDEE (BMR x 1.725) | 3,679 cal/day |
| Target Calories | 3,678 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 1.725 = hard exercise 6-7 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 | 188g | 752 | 20% |
| Carbohydrates | 502g | 2008 | 55% |
| Fat | 102g | 918 | 25% |
| Total | - | 3,678 | 100% |
Protein is set at 2.3g per kg of lean body mass (180 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 3678 cal precisely.
Plan 3 meals that total 3678 calories
Divide daily calories evenly: roughly 1226 cal per meal for a 240 lb woman. Each meal targets about 63g protein, 167g carbs, and 34g fat.
Hit 188g protein first
Protein is the lock, carbs and fat are the flex. 188g across 3 meals is 63g 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 126g of your 502g carbs in the meal 1-2 hours pre-workout and 151g 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 240 lb woman holding 3678 cal can skip breakfast and eat two larger meals, or spread across 5 smaller ones. What matters is hitting 188g 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 240 lb woman, train to preserve or slowly build lean mass. Pre-workout, 126g of your 502g daily carbs 60 to 90 min before lifting supports performance. Post-workout, 151g 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 188g protein target from becoming wasted at 3678 cal. Without resistance training, the body has no reason to preserve the lean mass these macros are built to protect, and your 3679 TDEE will drift down within a year.
Common pitfalls to avoid
At maintenance for a 240 lb woman on 3678 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 12 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 240 lb set point. Second pitfall: dropping training once calorie pressure is off. Without progressive resistance training, muscle mass slowly declines, which lowers your 3679 TDEE, which turns 3678 into 3578+ effective cal within a year. Lift 3 times a week minimum at 188g protein daily.
Frequently Asked Questions
Is 3678 calories per day too fixed for a 240 lb female?
3678 matches a 3679 TDEE almost exactly. For a 240 lb woman at very 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 188g of protein across the day for muscle protein synthesis?
Spread 188g across 6 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 3678 calorie target?
Yes. Keep protein fixed at 188g and swap carbs and fat freely — 10g of fat trades for ~23g of carbs. Two floors: fat above 82g (20% of calories) and carbs above 50g. Hit protein, land at 3678 calories, and the carb-fat split is yours.
Should I drink my calories or eat them at 240 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 3678 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 240 lb female?
The calculation uses the Katch-McArdle BMR formula. A 240 lb woman with an estimated 75% lean mass (180 lbs lean) has a BMR of 2133 calories. Multiplied by 1.725 for very active activity (Hard exercise 6-7 days per week), the TDEE is 3679 calories per day. For maintenance, the target matches TDEE at 3678 calories.
Why is protein 188g for maintenance at 240 lbs?
Protein for maintenance is set at 2.3g per kg of lean body mass. A 240 lb woman with 180 lbs of lean mass needs 188g of protein per day. At maintenance, 2.3g per kg of lean mass supports daily muscle repair and satiety.
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 1.725x estimate for very 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 240 lbs.
