- Track the weekly average, not daily numbers

- Do not weigh the day after your GLP-1 injection (common to see a temporary spike)
- Use trend lines in your app to see the real direction
Frequently Asked Questions
Is a smart scale worth it on GLP-1?
Yes. Smart scales auto-log your weight, track trends over time, and some measure body composition (body fat %, muscle mass). This data helps you and your provider evaluate progress beyond just the number on the scale.
How accurate is body fat measurement on smart scales?
Smart scale body fat readings (bioelectrical impedance) have a margin of error of 3-5% compared to DEXA scans. They are best used for tracking trends over time rather than as absolute values. Consistency matters more than accuracy.
What features should I look for?
Key features for GLP-1 users: weight tracking with app integration, body composition estimates, trend analysis, multiple user profiles, and a weight capacity of at least 400 lbs. Wi-Fi connectivity (vs Bluetooth only) provides more reliable syncing.
Which smart scale has the highest weight capacity?
The Withings Body+ and Renpho smart scales support up to 396 lbs. The Etekcity EB9380H supports up to 400 lbs. For patients above 400 lbs, the My Weigh XL-700 (non-smart, 700 lb capacity) is an option with manual tracking.
