A 140 lb sedentary female maintains current weight on 1,679 calories a day, matched exactly to a 1,678 TDEE. Protein at 109g protects the 105 lbs of lean mass that drive your metabolism, while 205g of carbs support energy demand and 47g 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 140 lb body weight while optimizing protein for muscle retention.
How These Macros Were Calculated
| Body Weight | 140 lbs |
|---|---|
| Estimated Lean Mass | 105 lbs (75% of body weight) |
| Lean Mass (kg) | 47.6 kg |
| BMR (Katch-McArdle) | 1,398 cal/day |
| TDEE (BMR x 1.2) | 1,678 cal/day |
| Target Calories | 1,679 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 1.2 = desk job, little or no exercise. 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 | 109g | 436 | 26% |
| Carbohydrates | 205g | 820 | 49% |
| Fat | 47g | 423 | 25% |
| Total | - | 1,679 | 100% |
Protein is set at 2.3g per kg of lean body mass (105 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 1679 cal precisely.
Plan 3 meals that total 1679 calories
Divide daily calories evenly: roughly 560 cal per meal for a 140 lb woman. Each meal targets about 36g protein, 68g carbs, and 16g fat.
Hit 109g protein first
Protein is the lock, carbs and fat are the flex. 109g across 3 meals is 36g 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 51g of your 205g carbs in the meal 1-2 hours pre-workout and 62g 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 140 lb woman holding 1679 cal can skip breakfast and eat two larger meals, or spread across 5 smaller ones. What matters is hitting 109g 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 140 lb woman, train to preserve or slowly build lean mass. Pre-workout, 51g of your 205g daily carbs 60 to 90 min before lifting supports performance. Post-workout, 62g 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 109g protein target from becoming wasted at 1679 cal. Without resistance training, the body has no reason to preserve the lean mass these macros are built to protect, and your 1678 TDEE will drift down within a year.
Common pitfalls to avoid
At maintenance for a 140 lb woman on 1679 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 7 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 140 lb set point. Second pitfall: dropping training once calorie pressure is off. Without progressive resistance training, muscle mass slowly declines, which lowers your 1678 TDEE, which turns 1679 into 1579+ effective cal within a year. Lift 3 times a week minimum at 109g protein daily.
Frequently Asked Questions
What should I do if I'm not maintaining weight at 1679 calories?
If your weight trends up or down consistently over 2 weeks at 1679 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 1679 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 1679 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 168 calories on training days and subtract 168 on rest days. Your weekly calorie total stays fixed.
Is 1679 calories per day too fixed for a 140 lb female?
1679 matches a 1678 TDEE almost exactly. For a 140 lb woman at sedentary 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 109g 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 109g 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.
Can I swap carbs for fat or vice versa within my 1679 calorie target?
Yes, within limits. Keep protein fixed at 109g and swap carbs and fat based on preference and training. Each gram of fat is 9 cal, each gram of carbs is 4 cal, so 10g of fat swaps for about 23g of carbs. The floor is fat not dropping below 20% of total calories (37g) to protect hormones, and carbs staying above 50g for brain and glycogen function. Within those bounds, a higher-fat day and a higher-carb day both work, as long as protein is hit and total calories land at 1679.
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 1.2x estimate for sedentary 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 140 lbs.
