Here’s something fun, a book written in 1900 called “The No Breakfast Plan and The Fasting Cure”. It’s a delightful time capsule written by an MD, a man of science, from a time before antibiotics, before insulin, before chemotherapy, when they still had diseases called “melancholia” and “dyspepsia”.
