Change your weight in your profile settings, save it, then sync your device so calorie burn and training numbers refresh.
If Garmin Connect is showing the wrong weight, a lot can feel “off.” Calories, load, and some training estimates can drift. The good news: updating your weight is usually a two-minute fix once you know where Garmin stores it and how syncing works.
This walkthrough covers the app and the web version, plus the common gotchas that make weight edits look like they didn’t save. You’ll finish with one clean number in the right place, and your watch and app matching again.
Why Your Weight In Garmin Connect Matters
Garmin uses profile weight in more places than people expect. It can affect calorie calculations, fitness features that rely on personal stats, and any connected services that pull body data from Garmin.
If your weight changed recently, or you set up a new phone, or you paired a new watch, Garmin might still be using an older profile value. A quick check can stop weeks of messy trends.
Two Weight Numbers Can Exist
Garmin Connect has a profile weight and, in many setups, a logged weight history. If you only change one of them, your charts can look odd. Your goal is simple: set your profile weight correctly, then confirm your weight logs are doing what you want.
Syncing Is The Step People Skip
After you save your new weight, your watch may still show the older value until it syncs. If you edit weight and close the app right away, your device might not get the update.
How To Update Weight In Garmin Connect On Phone And Web
Use the app if you want the fastest fix. Use the web if you prefer a larger screen or if the app menus look different on your phone.
Update Weight In The Garmin Connect Mobile App
Menu names can vary a little by phone model and app version, yet the path usually stays close to this:
- Open Garmin Connect on your phone.
- Open the main menu (often labeled More or shown with a menu icon).
- Go to Settings, then User Settings (or Profile depending on your layout).
- Find Weight, enter your current value, and save.
- Sync your watch (open the device sync screen or pull to refresh on the home page).
If you don’t see User Settings, try tapping your profile icon first, then look for profile or account settings. Garmin has a dedicated help page that describes where profile preferences live in the app and how they’re edited: Changing Account Preferences in Garmin Connect.
After You Save, Do One Extra Check
Reopen the same screen and confirm the value still shows your new weight. This quick re-check catches cases where the app didn’t save due to a weak connection or a stale session.
Update Weight In Garmin Connect On The Web
If you use Garmin Connect in a browser, you can edit your user profile there too:
- Sign in to Garmin Connect on the web.
- Open your account or profile settings.
- Edit your Weight value and save.
- Open the mobile app and sync, so your watch picks up the change.
Once saved, the updated profile weight should be consistent across web, phone, and watch after a clean sync.
Make Sure You Changed The Right Weight Field
Garmin Connect can show your weight in a few spots. Which one matters depends on what you’re trying to fix.
Profile Weight Versus Weight History
Profile weight is the number Garmin uses for calculations tied to your account settings. Weight history is the log used for graphs and trends. Many users want both updated. Some only want the profile updated and prefer their weight chart to stay untouched.
If your weight chart looks wrong after a profile edit, check whether a smart scale or a connected app is writing entries you didn’t expect.
If You Use A Garmin Index Scale
With an Index scale, weight entries can arrive through the scale sync rather than manual logging. If multiple people use the same scale, matching the right user profile matters, or a reading can land in the wrong place.
When you need to manually set body composition-related details tied to a scale setup, Garmin’s help content covers the device path inside the app and where those settings live: Manually Updating Body Composition Data in the Garmin Connect App.
Where Weight Changes Show Up In Garmin Metrics
After you update your profile weight and sync, you’ll usually see changes in calorie calculations right away. Some other metrics may update after your next activity, your next full-day sync, or a fresh calculation cycle.
| Area | What Changes | When It Updates |
|---|---|---|
| Calorie burn estimates | Energy numbers can shift because body mass is part of the math | Often right after a sync |
| Daily calorie goals | Targets tied to profile stats can adjust | After saving profile weight |
| Weight charts | Your trend line reflects logged entries, not just profile edits | When a new weight entry exists |
| Training load views | Some derived displays can look different across weeks | After new workouts sync |
| Third-party integrations | Apps connected to Garmin may pull the updated profile value | Next data pull or sync cycle |
| Watch profile screens | Your device profile can show the updated weight after it receives it | After successful device sync |
| Health summaries | Summary cards can reflect the new baseline and recent entries | After the app refreshes |
| Reports and exports | Exported data reflects what’s stored at export time | When you generate the report |
Step-By-Step: Clean Update That Sticks
If your edits keep “snapping back” to an older number, run this tighter sequence. It avoids most sync and caching quirks.
1) Update The Profile Weight
Use the app or web profile settings and save your new weight. Then reopen the same screen to confirm it still shows the new value.
2) Force A Fresh Sync
Open Garmin Connect and trigger a sync. Keep the app open until the sync finishes. If you use Bluetooth, stay close to your watch during the sync.
3) Restart If The App Feels Stuck
Close Garmin Connect fully and reopen it. On many phones, leaving the app “open in the background” can hold on to an older cached profile view.
4) Check Units Before You Panic
If you entered your weight in pounds but your account is set to kilograms (or the other way around), the number can look wildly wrong. Verify your unit settings, then correct the weight entry.
Fixes When Garmin Connect Won’t Show The Updated Weight
If you’ve saved the new number and synced, yet the app still looks wrong, it’s usually one of a small group of causes. This checklist keeps it simple.
| Symptom | Likely Cause | Try This |
|---|---|---|
| Weight changes, then reverts | Save didn’t stick due to session or connection issues | Log out and back in, edit again, then sync |
| App shows new weight, watch shows old weight | Device didn’t receive the update | Run a full sync with the app open until it finishes |
| Charts look wrong after profile edit | Weight history entries don’t match your intent | Review logged weights and remove accidental entries |
| Weight units look off | Unit setting mismatch | Confirm kg/lb setting, then re-enter weight |
| Index scale entries land on the wrong user | Scale user selection mismatch | Confirm the scale user mapping in device settings |
| Weight updates in one place only | Edited history but not profile, or the reverse | Update profile weight, then verify the weight log view |
| Connected app keeps overwriting weight | Another service is pushing a value into Garmin | Pause the connection, set weight in Garmin, then reconnect |
Tips For Keeping Weight Data Clean Over Time
Once your weight is correct, a little routine keeps it from drifting again.
Pick One “Source Of Truth”
If you use a smart scale, let it write your weight entries and avoid manual edits unless you’re correcting a bad reading. If you don’t use a scale, decide how often you’ll log weight so your chart stays consistent.
Sync After Big Account Changes
When you edit profile details like height, weight, or units, do a sync right after. If you recently set up a new phone, re-pair your watch and run an extra sync to pull your full profile back down.
Watch For Multiple Users On One Device
Households with more than one Garmin user can run into mixed data if a scale guesses the wrong person or if someone logs into the app on a shared phone. A quick check of the signed-in account prevents most mix-ups.
Mini Checklist Before You Close The App
- Profile weight shows the correct value on the edit screen.
- Units match what you intended (kg or lb).
- Sync completed and the watch reflects the updated profile.
- Weight history view matches your logging style.
If those four items look right, you’re done. Garmin Connect should now use your updated weight for current calculations, and your device and app should stay in sync.
