I eat a carnivore diet and have had MAJOR health improvements. My husband is on keto and swears he'll never go back to sugar or carbs--too addictive. Also-I highly recommend another book about sugar and cancer (and Nazis) called Ravenous: Otto Warburg, the Nazis, and the Search for the Cancer-Diet Connection. The story details how Warburg first observed the deranged cellular respiration of cancer cells and how they "ferment" rather than using oxygen for energy. It's also a fascinating look at the history of science and the character of one brilliant, if narcissistic, man.
