If you want to know if some device is effective, there is a standard way to demonstrate it: a clinical trial. This is precisely what has been done on the impact of wearables on weight loss. And the result is:
Among young adults with a BMI between 25 and less than 40, the addition of a wearable technology device to a standard behavioral intervention resulted in less weight loss over 24 months. Devices that monitor and provide feedback on physical activity may not offer an advantage over standard behavioral weight loss approaches.That's amazing! Why is there so many articles pushing wearables for weigth loss when there are very few clinical trials, and their results are clearly against their use?. This is a marketing bubble and somebody should tell clearly that they could use wearables but for other reasons.
PS. Let's imagine that somebody wants to relate wearables for weight loss reduction with insurance premiums! Nothing to add.
