Maintaining 170 lb as a sedentary female means 1,942 cal daily: 133g protein, 231g carbs, 54g fat. These numbers match your 1,942 TDEE exactly, with protein weighted to hold 128 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.

Eating at TDEE with zero deficit or surplus. These macros maintain your 170 lb body weight while optimizing protein for muscle retention.
How These Macros Were Calculated
| Body Weight | 170 lbs |
|---|---|
| Estimated Lean Mass | 128 lbs (75% of body weight) |
| Lean Mass (kg) | 57.8 kg |
| BMR (Katch-McArdle) | 1,618 cal/day |
| TDEE (BMR x 1.2) | 1,942 cal/day |
| Target Calories | 1,942 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 | 133g | 532 | 27% |
| Carbohydrates | 231g | 924 | 48% |
| Fat | 54g | 486 | 25% |
| Total | - | 1,942 | 100% |
Protein is set at 2.3g per kg of lean body mass (128 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 1942 cal precisely.
Plan 3 meals that total 1942 calories
Divide daily calories evenly: roughly 647 cal per meal for a 170 lb woman. Each meal targets about 44g protein, 77g carbs, and 18g fat.
Hit 133g protein first
Protein is the lock, carbs and fat are the flex. 133g across 3 meals is 44g 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 58g of your 231g carbs in the meal 1-2 hours pre-workout and 69g 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 170 lb woman holding 1942 cal can skip breakfast and eat two larger meals, or spread across 5 smaller ones. What matters is hitting 133g 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 170 lb woman, train to preserve or slowly build lean mass. Pre-workout, 58g of your 231g daily carbs 60 to 90 min before lifting supports performance. Post-workout, 69g 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 133g protein target from becoming wasted at 1942 cal. Without resistance training, the body has no reason to preserve the lean mass these macros are built to protect, and your 1942 TDEE will drift down within a year.
Common pitfalls to avoid
At maintenance for a 170 lb woman on 1942 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 170 lb set point. Second pitfall: dropping training once calorie pressure is off. Without progressive resistance training, muscle mass slowly declines, which lowers your 1942 TDEE, which turns 1942 into 1842+ effective cal within a year. Lift 3 times a week minimum at 133g protein daily.
Frequently Asked Questions
What foods hit 133g protein, 54g fat, and 231g carbs?
Protein: chicken breast (31g per 100g), eggs (6g each), Greek yogurt, or protein powder. Fat: olive oil or peanut butter (14g per tablespoon). Carbs: cooked rice (45g per cup) or oats (27g per cup). A food tracking app is the most reliable way to hit exact targets.
How does my activity level affect my 1942 calorie target?
Your Sedentary activity level uses a multiplier of 1.2, giving a TDEE of 1942 calories. Activity multiplier is the single biggest variable in your calorie target — getting it right matters more than fine-tuning macro splits. If your weight doesn't respond in 2 weeks, your activity level is likely misestimated.
What should I do if I'm not maintaining weight at 1942 calories?
If your weight trends up or down consistently over 2 weeks at 1942 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 1942 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 1942 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 13594 calories.
Is 1942 calories per day too fixed for a 170 lb female?
1942 matches a 1942 TDEE almost exactly. For a 170 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.
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 170 lbs.
