The Hidden Biological Switch That Can Be the Source of Weight & Fat Gain with Dr. Richard Johnson

Why do so many people struggle with weight gain and obesity? Here’s one reason: A biological switch in our bodies designed to protect us from starvation can become stuck in the “on” position. This is a hidden source of weight gain, heart disease, insulin resistance, and other health challenges. But it’s not a life sentence; this switch can be turned off. In this episode, JJ talks with one of her heroes, Dr. Richard Johnson. He’s a practicing physician and an internationally recognized medical scientist researching obesity and diabetes, with a special interest in the role of sugar, especially fructose. Dr. Johnson explains why fructose is so different from other sugars and why it can be so problematic. You’ll learn why fructose can encourage fat storage, how this switch is being activated when we’re not in survival situations, the types of foods that can activate the switch and the behaviors that can turn things around. They also discuss leaky gut and its relation to food allergies, the role of fructose in damaging gut health, and how this sugar may be associated with dementia. This conversation gives you specific things you can do to help prevent this survival switch from causing weight gain and other health challenges in the long run.
