I'm still early on into the book but so far i cant see anything that will cause harm . He talks alot about modern lifestyle and how that effects everyone in the family and why . I dont need to lose weight and find the explanation of whats going on in your body with lifestyle and food very interesting as i dont know anything about the subject . Not being over weight means i dont read a lot of diet books . It was suggested to me by a friend who's a fitness instructor when i mentioned i race TT's but at a loss when it comes to diet to support my training .
