Adherence
Adding mobile diet monitoring apps and Twitter-based social support to a theory-based podcast weight-loss intervention does not enhance weight loss compared to the podcast alone.
If you are trying to lose weight, adding a calorie-counting app and a social media group to your routine may not give you any extra benefit if you are already following a structured plan. The study suggests that a simple, consistent plan (like listening to weekly podcasts) can be just as effective as a complex digital regimen, provided you stick to it. Do not assume that more technology equals better results.
prompting and mobile communication via Twitter and monitoring app without feedback did not enhance weight loss.
Why this rating
