Adherence
A 3-month multicomponent mobile health intervention (smartphone app + smart band + brief counseling) produces statistically significant but clinically modest weight loss and body composition improvements in overweight/obese adults compared to brief counseling alone, but these benefits are not maintained at 12 months after device removal.
Using a smartphone app and fitness tracker for 3 months can help you lose a small amount of weight and improve body composition if you are overweight or obese. However, this benefit disappears after 3 months if you stop using the devices. To maintain weight loss, you must transition the habits learned during the 3-month period (like self-monitoring and dietary awareness) into your daily life without relying on the technology.
The low-intensity intervention of the Evident 3 study showed, in the IG, benefits in weight loss, some body composition variables, and time spent in light physical activity compared with the CG at 3 months, but once the devices were collected, the downward trend was not maintained at the 12-month follow-up.
Why this rating
Randomized controlled trial with large sample size (N=650) and intention-to-treat analysis, though adherence to the app varied.
