Why Sugar And Fructose Are So Deadly with Dr. Richard Johnson

Episode 540 1h 14m


We’ve been set up for failure when it comes to our metabolic health. Eighty-eight percent of people are metabolically unhealthy, and since the 1920s we’ve shamed them into believing it’s their fault—that they should just eat fewer calories and exercise more. But the real culprit is sugar and the processed foods that contain it. The majority of foods on our market shelves contain insane amounts of added sugar and high-fructose corn syrup—ingredients that literally slow down our metabolism and turn on our internal fat storage switch. That means we have the power to turn that switch off by choosing to use food as medicine.

Today, I’m excited to talk to Dr. Richard Johnson about how our biological fat storage process works and what we can do to positively affect it. Dr. Johnson and I dive into the real biological problem with sugar and why our bodies are designed to store fat in response to it, especially in the form of high fructose corn syrup. It’s not simply a matter of calories in, calories out.

There is a ripple effect happening inside each of us, from our hormones to our microbiome and more, and the quality of information from our food will dictate whether our systems function better or worse. Mitochondrial function is an essential part of the conversation if we want to support optimal metabolic health and longevity. Dr. Johnson and I discuss how to support these energy factories, along with the importance of reducing oxidative stress and the negative impacts of fructose using key nutrients like vitamin C. We live in a food environment that can make it hard to maintain a healthy metabolism, but with the right choices, it’s ultimately in our control. Reducing our sugar intake is a huge step in the right direction.
