A calorie goal that adjusts to your progress.
The formula provides a starting estimate. With enough food and weight entries, Mira adjusts your goal each week.
Free in the Mira app.
How it works
- 1
Starting goal
Mira uses resting energy from the Mifflin-St Jeor equation, your activity level and your chosen pace.
- 2
Food and weight entries
Adjustments need at least 14 days of history, 10 fully logged days and 4 weigh-ins.
- 3
Weekly adjustments
Mira gradually changes the goal based on logged food and your weight trend.
Small, steady steps
A weekly change is capped at 100 kcal at first, so the goal never jumps around.
Limits on the calculation
The pace is capped at 1% of body weight a week, the deficit at 25%, and a minimum calorie limit applies.
Independent of workout estimates
Adjustments use logged food and your weight trend, rather than calorie burn estimated by a watch.
You stay in charge
Prefer a fixed number? Set your goal by hand and Mira leaves it alone.
Questions
Why does my goal change?
Your starting goal is an estimate from a formula. Once you have enough food and weight entries, Mira adjusts it based on your weight trend.
Is it free?
Yes, the adaptive goal is part of the free app.
When does it start adapting?
After at least 14 days have passed and you have 10 fully logged days and 4 weigh-ins.
