I find this book to be a quick summary of all things true about nutrition. 41 pages, about a half an hour read. Some of the best minutes spent in your life.

Here are summaries in Estonian and English from the book itself:
One day I wish to also be abled to say fuck calories and fuck macros and just eat my real LCHF food without weighing anything. This day will come and it will come soon. My body is smart enough to make good decisions without me calculating long and hard with my brain (and my iPhone or other gadgets).
