This book is like others by Michael D’Aulerio. It’s not necessarily poorly written or bad, but it is very repetitive. The 5% of the text the presented new or useful information was well done and informative. It would have made a great blog post or article, however, in an attempt to stretch it out, D’Aulerio adds a great deal of repetition, most of which includes patting himself on the back. He also spends far more time extolling the benefits of fat adapted running than he does offering practical “how to” advice. This title is available for low cost on the kindle and is free for Kindle Unlimited members … which is how I would recommend you get it. I certainly wouldn’t spend any money on it as the truly useful information can also be found via a web search.
