Energy Calculator
Maintenance Calories by Activity Type
Estimate your daily maintenance calories using your body stats and training activity level.
What this tool does
Calculates your estimated BMR and maintenance calories, then suggests practical starting targets for fat loss or lean gain.
Who and when to use it
- Anyone setting a calorie target for a new nutrition phase.
- Users whose body weight trend has stalled and needs recalibration.
- People adjusting intake based on activity level changes.
Step-by-step usage
- Enter sex, age, weight, and height.
- Select the activity level that best matches your real week.
- Calculate maintenance, then choose either cut or lean-gain target.
- Track 2 weeks of scale trend and adjust by 100–150 kcal if needed.
Example interpretation
If maintenance is 2,450 kcal/day, a reasonable cut start might be ~2,050–2,200 kcal/day. For lean gain, ~2,550–2,700 kcal/day is often a safer first step than aggressive surpluses.
FAQ
Is this an exact maintenance number?
No. It is a starting estimate that should be validated against real weight trend data.
How do I choose activity level correctly?
Choose based on your full week, including non-exercise movement, not just hardest training days.
How quickly should I adjust calories?
Usually every 10–14 days, using average weight trend and recovery markers.
Can stress and sleep shift maintenance?
Yes. Low sleep and high stress can affect appetite, activity, and energy expenditure.
