How to Find Your Maintenance Calories
Your maintenance calories are the average daily intake that keeps your weight stable over weeks — not a single perfect day on the scale.
The practical method: start with an estimated TDEE, eat near that number, then adjust from a two-week average weight.
Why “maintenance” is an average
Daily weight swings from water, sodium, carbs, hormones, and gut content. Maintenance is the intake where your weekly average weight is roughly flat.
If you eat “maintenance” and keep trending down, your true maintenance was lower than the estimate. If you trend up, it was higher.
Step 1: Get a calculator starting point
Protealpes estimates resting burn with Mifflin-St Jeor, then applies an activity factor for TDEE:
- Open the TDEE calculator (or calorie calculator set to maintain).
- Enter sex, age, height, weight, and a realistic activity level.
- Write down the TDEE as Week 0 estimate.
Do not pick “extra active” because you want a bigger food budget.
Step 2: Log intake honestly for 14 days
- Weigh or measure habitual foods when you can.
- Count cooking oils, sauces, and drinks.
- Aim to average within ~100–150 kcal of the estimate each day.
- For mixed plates, use the AI meal analyzer (text, photo, or both) and prefer USDA-matched rows when shown.
Missed logging days break the experiment. Two clean weeks beat four messy ones.
Step 3: Weigh in like a scientist (simple version)
| Habit | Why |
|---|---|
| Same time daily (e.g. morning, after bathroom) | Cuts noise |
| Similar clothing | Consistency |
| Weekly average of 7 mornings | Ignores one salty dinner |
| Compare week 1 average → week 2 average | Finds the trend |
How to read the trend
| 2-week average change | Likely meaning | Adjustment |
|---|---|---|
| Flat (±0.2–0.3 kg) | Near maintenance | Keep intake |
| Down ~0.25–0.5+ kg/week | In a deficit | Raise ~100–200 kcal if you wanted maintenance |
| Up ~0.25–0.5+ kg/week | In a surplus | Lower ~100–200 kcal |
Large swings may be water. Look at the direction across weeks, not one morning panic.
Step 4: Lock a working maintenance number
After the check:
Working maintenance ≈ average daily calories eaten during the flat period.
That number is more valuable than any single calculator output. Recalculate after meaningful fat loss or gain.
Worked example
- TDEE estimate: 2,400 kcal
- You average 2,380 kcal for 14 days
- Week-1 avg weight: 78.2 kg → Week-2 avg: 78.1 kg (flat)
Maintenance for now: ~2,400 kcal.
If weight fell 0.6 kg across those two weeks while logging was tight, true maintenance might be closer to 2,200–2,250 kcal — cut less aggressively next time, or raise intake to re-test.
Maintenance calories vs goal calories
| Goal | Relative to maintenance | Tool |
|---|---|---|
| Hold weight | ≈ maintenance | TDEE calculator |
| Fat loss | Moderate deficit (often ~15–20%) | calorie deficit calculator |
| Muscle gain | Small surplus (often ~10%) | calorie surplus calculator |

Mistakes that fake “broken metabolism”
- Weekend blowouts not logged
- “Bitesthemselves” of peanut butter ignored
- Activity factor ego inflation
- Cutting from BMR instead of TDEE (see BMR vs TDEE)
- Changing five variables at once (sleep, sodium, training, calories)
Key takeaway: Calculators suggest maintenance. Two weeks of average weight confirm it. Adjust 100–200 kcal at a time.
FAQ
Should I eat the same calories every day?
A daily average is enough. Some people eat more on training days and less on rest days as long as the weekly mean hits the target.
Do steps change maintenance a lot?
Yes. A job that adds 8,000 extra steps can move TDEE hundreds of calories. Re-test when lifestyle changes.
Is maintenance different for women during the cycle?
Scale weight often fluctuates. Use longer averages and judge fat-loss trends across full cycles when possible. Educational guidance only.
Can I use a wearable’s calorie burn as maintenance?
You can, but verify with weigh-ins. Wearable burn estimates vary widely by brand and sport.
What if I hate tracking?
Track tightly for 14 days to find the number, then use simpler portion rules — and spot-check meals with the analyzer when portions drift.

Start with the TDEE calculator, eat near that number for two weeks, then refine. For a goal target with educational floors, use the calorie calculator. Not medical advice.
