Telehealth and digital health interventions have nowadays become important tools to distribute health-related services and information via electronic information and telecommunication technologies. By bringing lifestyle intervention online, patients can now be shared important data on their lifestyle habits, such as food intake, exercise, sleep, medication and so on. On the other hand, these techniques provide a platform where primary care physicians can conveniently refer patients to a health coach or dietician for any sort of support and follow-up.
