Who or what is to blame for us getting fat and ill in increasing numbers? Sugar or fat? Gut microbes or genes? Laziness or poverty? Whatever it is, it's placing a devastating burden on our healthcare system, and scientists in every field are desperate to explain this epidemic and stave off a modern health disaster. Anthony Warner, author of The Angry Chef is back, and he wants answers. In The Truth About Fat he scrutinises the explanations of academics, doctors, researchers and journalists. He lays out the best evidence available, rails against quack theories preying on the desperate and considers whether we are blaming our bodies for other people's ignorance and cruelty. What remains is the unvarnished truth about one of the great preoccupations of our age.
