Withings, Strava and Libre in one tracker: calories in versus out
Most people have the pieces: a smart scale, a running or cycling app, maybe a glucose sensor, and a food log that lives somewhere else. MetaBraid pulls them into one account, so calories in versus calories out is one picture, not three apps you never compare.
What each connection adds
| Source | What MetaBraid pulls | What you see |
|---|---|---|
| Meals (photo or description) | Your own log | Calories, protein, carbs, fat and ingredients per meal, and calories in per day |
| Withings scale | Weight, body fat and muscle mass | Weight and body fat charts, and BMR used for calories out |
| Strava | Start time, sport, distance and calories burned | Exercise calories added to calories out each day |
| FreeStyle Libre 3 (via LibreLinkUp) | Glucose readings | Latest reading and a table of recent readings |
How calories in versus out is calculated
Calories in come from the meals you log. Calories out combine your resting energy use from Withings with the calories burned reported by Strava. The Today screen then shows the difference as a signed daily balance: above zero means you ate more than you used, below zero means less. See the TDEE calculator for how resting energy and activity are estimated.
Why bring them together?
- Less guessing at the scale. Weight moves around day to day. Seeing it against a week of food and training makes the trend easier to trust.
- Honest after a workout. Exercise calories sit next to food rather than in a separate app.
- A weekly insight. MetaBraid turns your last week of food, training, weight, body fat and goal into specific next steps.
- Glucose, if you use it. Libre readings are in the same account as your meals. Read how to use that in the Libre 3 dashboard guide.
