Summary

This study tested whether weighing yourself daily with a wireless scale can help adults with obesity manage their weight. About 400 people from primary care clinics took part. They were asked to weigh themselves each day and see their weight trend on the scale's display. The goal was to see if this simple habit could prevent continued weight gain over two years.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
daily self-weighing with a wireless digital scale
What this could lead to
If it works, this simple habit could help people with obesity prevent further weight gain without expensive programs.
What could go wrong
This is a behavioral study, not a drug or device. Results may vary, and long-term adherence to daily weighing is uncertain.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age 19-65 years * Body mass index (BMI) 30 - 50 kg/m2 * Receives care at one of the participating primary care clinics * Resides in one location at least 5 days each week * Possesses a smartphone with data plan * Wi-Fi or Bluetooth internet connection in home Exclusion Criteria: * Pregnancy or anticipating pregnancy during study duration. This is a weight loss study and weight gain/loss due to pregnancy and/or delivery would confound study results. Additionally, weight loss is not recommended for pregnant women. * Unwilling or unable to do any of the following: give informed consent, accept random assignment, attend five measurement assessments * Likely to relocate and no longer be seen at UAB primary care in the next 2 years * Weight loss ≥5% of body weight in past 6 months (other than postpartum) * Weight \>180 kg (396lbs) due to the limitation of the scale being used. * Current participation in another weight loss study * Bariatric surgery or revision in the past two years * Prescription weight loss medications within the past 6 months * Another household member already participating in the study * Potential participants living farther than 50 miles driving distance from UAB will be excluded from the study. It is expected that those living farther away will be more difficult to retain as study participants.
