Bad news: 93% of Americans are metabolically unhealthy. Their bodies struggle to convert food into the energy their cells need. And this fuel shortage underlies all sorts of conditions, from diabetes and cancer to insomnia and erectile dysfunction.

Good news: Simple changes to how we eat and exercise can dramatically improve our metabolic health.

This is the thesis of “Good Energy: The Surprising Connection Between Metabolism and Limitless Health” by Casey Means. A Stanford-trained physician, Casey grew disillusioned with conventional healthcare when she realized that many doctors are great at prescribing pills and performing surgeries but hopeless when it comes to addressing root causes. This led her to leave traditional medicine and focus on combating metabolic dysfunction, which she believes is at the heart of America’s health crisis.

Today on the show, she tells Rufus about her journey, explains why she thinks the medical system fails patients, and shares the simple biomarkers that you should check to see if you’re at risk for a deadly disease.

📱 This is part one of our interview with Casey. Part two will be available here on Thursday. But if you can't wait that long, you can listen right now on the Next Big Idea app: https://nextbigideaclub.com/app/
