"A total waste of time"
I kept waiting for the authors' ideas to become clear and they never did.
Go to conferences? Wow! what advice. I bet the authors give a lot of those.
"Not worth it"
Very shallow on content.
Full of bible quotations which discredit and disctract from the attempt to explain the scientific benefits of fasting.
A ridiculous number of references to the author's other publications.
"Fantastic"
Fantastic mix of humour and hard-hitting, well-researched fact.
