Hi, s93. I'll second Teaser's recommendations. Dr. Atkins' books are easy to read, and think through, and very encouraging.

Dr. Bernstein's book explains a lot. His book was what gave me the courage to stay around 30 grams of carbs, for life.

I also like Life Without Bread, by Wolfgang Lutz. It addresses what metabolism is, how different kinds of diets change the way organs work. It's a fascinating book.

I have other favorites, but those three are ones I would give as presents, if someone were really interested in the how and why of the necessity of low carb living.

I like the books of the early low-carb pioneers, too.

Dr. Blake Donaldson's, Strong Medicine, is really good food for thought. It can be read, without charge, at HathiTrust.
