“is the obesity story related to the overeating of glucose in the cancer cell um and i think those two stories are related and that's why you know the last part of my book is really a focus on hyperinsulinemia because i think it's the piece that puts it all together it could explain the obesity it could explain uh the cancer and it could explain why cancer was once a rare disease and then in step with diabetes and obesity and other you know quote unquote diseases of civilization became much more common”
