Tushar Vashisht, Co-Founder and CEO of Healthify (Fund II), is on a mission to reverse this.
In his AI Forward talk at Blume Day 2026, he makes the case that we might be at the precipice of eradicating obesity within this century.
Two forces are converging to make this possible:
GLP-1s that change biology: These drugs deliver 15-25% weight loss on average, nothing like this has existed before. But there's a catch: muscle mass drops, and when you stop, the weight bounces back. Healthify's companion program, HealthifyRx, tackles exactly this. In their first 2,000 users, muscle mass actually went up by 4.2%.
AI that changes behavior: Healthify analyzes signals from your body (nutrition, steps, sleep, heart rate, glucose), and gives you timely, proactive feedback through Riya, their AI companion. Not generic advice, but coaching that actually knows your context.
Neither force works as well alone — GLP-1s without behavior change is a temporary fix, and behavior change without GLP-1s is a slow grind. Together, they make lasting, healthy weight loss possible.
