The Claim
A web-based weight loss program delivered via Facebook Messenger and a custom platform achieved a 60% retention rate at 6 months in Mexican adults with overweight or obesity, and this retention rate is comparable to those reported in other digital weight loss interventions.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In a study of Mexican adults with overweight or obesity, a digital weight loss program delivered through Facebook Messenger and a custom platform kept 60% of participants engaged for six months, which matched retention rates seen in other digital weight loss programs.
See the scientific wording
In a randomized controlled trial of Mexican adults with overweight or obesity, a web-based weight loss program delivered via Facebook Messenger and a custom platform achieved a 60% retention rate at 6 months, which is comparable to retention rates reported in other digital weight loss interventions, suggesting that digital delivery can sustain engagement in this population.
Receiving consistent messages and feedback through a phone app triggers brain reward signals that make people keep doing the behavior, like checking the app and following diet plans, because the brain learns to associate the app with positive outcomes.
What the research says
1 studyIn a study of Mexican adults trying to lose weight online, 60% stuck with the program for six months — which is about what other online weight loss programs see, so it works well for this group.
