Adherence

Mobile health (mHealth) applications and wearable technology can lead to modest reductions in body weight and BMI, but long-term benefits may diminish once device usage stops, suggesting the Hawthorne effect or need for continuous engagement.

Using a fitness tracker and health app can help you lose a small amount of weight and improve your BMI, but you must use it consistently. If you stop using the device, the benefits may disappear. To make it work, integrate it into your daily routine and consider it a tool for accountability rather than a magic solution.

At the 3-month mark, the intervention group experienced an average weight loss of 0.26 kg, a BMI reduction of 0.06... However, after the devices were collected at this mark, this downward trend was no longer observed [67].
