I think an online/social media health promotion program using sensors on phones or (low cost) smart bands/watches could kick up a health trend that clear the way for many other programs.

Taking ‘Fitbit’ as a case study. Fitbit provides incentives to live ‘actively’, motivational/emotional [SMS/Notification] prompts to stay active, community forum to stay engaged, and ‘prestige’ of being active. [Albeit, at relative high cost for low-income people in many countries.]

Perhaps, a low/non profit group could do that with appropriate emotional styles and tools for Thais.
