Another book that claims to be right about things that are the opposite of others. Cholesterol is bad, no it's good, fat is a killer, no fat is a perfect nutrient. Who are we supposed to believe? I'm not sure about anything it seems. He mentions studies, but so do the others. I just don't know how to tell what is true and what is not. I guess I'll need to research this, now, and try to come up with a conclusion on my own, again. I'm working on it... can you tell I've read a lot of hype, but am tired of not having definitive evidence/direction? ( )

Gluten and glucose are gonna kill us us...

Mind blowing stuff in this book. Stuff you've heard about, read about, or studied in class.

For instance: How come I put out of my mind that testosterone is made from cholesterol AND that cholesterol is a precursor for Vitamin D?

Took a grad level nutrition class in college by mistake. It was nothing but witchcraft and applied biochemistry. Scared me to death but I learned a lot.

He even talked about advanced glycation end products and prions!

More in depth review pending. ( )

I've been doing the keto diet for several months (now doing a "cyclical keto," I guess). I've lost 25+ pounds, eat less, crave less, and feel more energetic and better. This book provided some of the scientific underpinnings to explain why the keto diet has worked for me.

In a nutshell: carbs, sugar, and gluten are bad. They encourage fat growth, mess with insulin and blood sugar levels, and are poor fuel for the brain.

The book, of course, goes into greater detail. There are references to Dr. Perlmutter's own patients and protocols, there are references to scientific/medical studies, and there are numerous sources. Now, I know that many doctors and dieticians poo poo this type of low carb and high fat diet. But, I can say it has worked for me. I will remind everybody that eggs were once considered the worst, but now they are seen as nutritious. I will, as a historian, note that we eat far more carbs, gluten, and sugar in the 20th and 21st centuries than we ever did in previous centuries and we've gotten fatter. I don't think one could or should do this type of diet at all times, or forever, or with no breaks. But, I think that this type of diet is the wave of the future (and of the past). ( )

A lot of reviewers complain that this title is very repetitive. It is but for the audiobook that is alright. It is very easy for much of what the author wrote to slip right by especially if I'm doing other stuff while listening. I'm not convinced that this diet is for everyone, but I am convinced that for the people who need this diet that it is life changing. I'll change my food choices some based on this book and definitely watch for future news on this topic. ( )

There is a quite a bit of "marketing" of the author's "diet plan" spread throughout the book.

The author seemed loathe to actually call his eating plan what it is: Keto. Though, he does permit legumes/beans, so maybe it is a Keto-Paleo hybrid. But he is extremely anti-gluten and, to a much lesser extent, anti-sugar.

I liked hearing about another take on the low carb lifestyle; I did not like his upselling of his own stuff (since I already bought this book, he got enough of my money). I listened to this in audio format, but might have preferred this in print, so I could look back at the info in select chapters of interest to me. If you already follow a gluten free and/or a keto diet, there is nothing new in this book. ( )
