Description

Can you actually catch obesity from your friends? The answer from a massive 32-year analysis might shock you. In this episode of What The Study Says, Dr. Kai and Dr. Mai dive deep into the groundbreaking Framingham Heart Study to explore if obesity is contagious in a social sense. We analyze how social networks impact weight gain, finding that having an obese friend increases your risk by a staggering 57%. Beyond just diet and exercise, we discuss the difference between homophily and induction, revealing how social norms and esteem within your circle drive health outcomes. Join us as we uncover why social distance matters more than physical distance and how we might use these powerful social forces to spread positive habits instead.
