Old advice bottled up new (with a vegan hard sell)
on 24 March 2017
I got this book from the public library, not from Amazon. It is quite engaging and explains the usual, most common issues regarding modern, processed food and our unhealthy approach and behaviours towards eating etc. Where it starts to become problematic is, when it deviates from the initial promise, that there will be "no effort" and "no radical change" involved, and that, therefore, the 21 days will be very easy. Nice suggestion, but misleading, because after that the hard-sell starts, which insists that the only way to succeed is to turn vegetarian, or, more preferably, vegan. For many (overweight) people, this is likely to be a quite radical change, and not always simple, in the short and long run.
Whatever emotional charm or so-called scientific argumentation the author uses to convince, he would need to acknowledge, that he basically breaks his promise - even if so with best intentions. He cashes in on his (I assume) medical background and therefore implied authority, even though the claim "this program is clinically proven" (whatever this really means) omits, that any conscious structured change to eating and exercise will bring some (at least short-term) results in overweight people.
Apart from this, unfortunately, the book hardly provides anything "new" (if this is what people are after), yet again, it suggests, that it has discovered a novel approach. Old wine in new bottles comes to mind. Sure, it is hard nowadays to come up with anything really different, because the principles of how we get overweight (and how we would normalise our weight again) are just the same as thousands or millions or years ago - there simply is no revolution to expect on that front. However, perhaps writers of such books should generally stop claiming, that they have finally, and exclusively, found "the Holy Grail".
The last thing here is, that the book tries to be both, a motivational advice book, as well as a cooking book. I do not think that this really works, just on a practical level (would you really keep this book in the kitchen?). A cooking book with a separate pamphlet (to take out) on attitude towards food etc. would probably be better.
