Homeopathic Behavior Change in Public Health for Obesity

July 23, 2023 — Slowly, but surely, the world is waking up to realize that obesity is not a problem of bad behavior by the people who live with it.

A Cluster of Unreliable Prevention Studies

March 18, 2023 — The search for effective prevention strategies in obesity is daunting. For decades now, researchers have been casting about for effective ways to educate, nudge, or cajole groups of people into moving more and eating less or better.

Heartwarming Family Meals Prevent Obesity?

April 9, 2021 — Nostrums for overcoming obesity litter the landscape of health policy. “Obesity is preventable,” says the World Health Organization. We like the can-do spirit this reflects.

It Works! But Don’t Look Too Close at the Data

March 12, 2018 — Are we numb to hype and little lies yet? Sad to say, they’re not confined to tabloid news or politics. Despite data that doesn’t support effectiveness claims, we see such claims for obesity treatment and prevention published in scientific journals. This week, researchers at Johns Hopkins and UC-Davis provide two distinct examples. A Virtual Health […]
