Dr. Mark Hyman: The Keto Diet Can Reverse Chronic Disease and Boost Brain Health

Dr. Mark Hyman explains how the keto diet can cure diabetes, Alzheimer's, cancer, schizophrenia and more.

"It activates the brain's repair systems."

"It helps cognitive function at every level... from autism, to Alzheimer's, to schizophrenia, to depression."

"Sugar is really driving this big problem—sugar and starch... When you eat these foods, your body gets dysregulated. And when you use a diet that actually shuts off these cravings... it doesn't take long."

"In five or ten days, we get a 70% reduction from all symptoms and all diseases by people just changing their diet."

"[It's] incredibly helpful for longevity, it's helpful for reversing chronic diseases. And across all these diseases, we're seeing the same thing happen."
