This episode is featured in USA News. Blood sugar shouldn’t feel like a roller coaster. We sat down with functional medicine expert Dr. Kevin Smith to unpack how metabolism really works —across hormones, immune function, gut health, and brain — and why so many people feel hungry, foggy, and exhausted even while “doing everything right.” Dr. Smith explains insulin resistance in plain language, how to achieve hormone balance, nutrition tips, how cells make ATP, and the hidden ways stress and sleep shape glucose levels. He also challenges old grazing advice and shows how intermittent fasting and smart macronutrients can re-sensitize insulin, stabilize energy, and support autophagy for cellular cleanup.
