K-Wellness is not a marketing label. It is the systematized integrated model — quantitative measurement → multi-marker assessment → personalized prescription → lifestyle coordination — validated through 12-week transformation programs at Korean metabolic clinics. This model lines up precisely with the academic standard: BMI limits, body composition + lifestyle assessment, personalized behavior prescription — Ross 2020, DPP, Look AHEAD, Wing & Phelan all point the same direction. HAVIT is the digital entry point that makes this methodology accessible to US and global users. HAVIT is a non-clinical daily tracking tool.
