Your Doctor Says You're Obese, Your Mirror Says Nonsense. What Does Science Say?
For more than two decades, I've worked to help people understand obesity, and one thing has become increasingly clear: we cannot explain this disease with a simple equation of calories in versus calories out.
In this episode of the Nature and Science Podcast, I join host Don Murphy to discuss why obesity is far more complex than most people realize. We explore how genetics, epigenetics, early-life development, and the biology of fat cells influence body weight, and why the body has powerful mechanisms designed to defend it.
We also discuss why obesity should be understood as a chronic disease rather than a failure of willpower, how the environment before birth can influence long-term metabolic health, and why families need better access to evidence-based pediatric obesity care.
My goal is to help move the conversation beyond blame and outdated assumptions. When we understand the biology behind obesity, we can make better decisions about treatment and give patients and families the support they deserve.
In this episode, we explore:
Why the calories-in-versus-calories-out model doesn't tell the whole story
How genetics, epigenetics, and prenatal influences shape metabolic health
Why fat cells are active biological organs, not simply energy storage
Why obesity is a disease, not a moral failing or lack of discipline
The barriers families face when seeking childhood obesity treatment
I hope this conversation challenges what you think you know about obesity and encourages a more scientific, compassionate approach to care. The more we understand the disease, the better equipped we are to treat it.
