Forty pounds in less than 3 months is a major achievement - congratulations! And, that book by Trager and the Atkins nutritionist Collette H. is a great one. I have it right alongside the updated Atkins book and refer to both of them regularly. What I like about the Trager book is that it delves a bit more deeply into some of the mental/psychological aspects of losing weight and there's a bit more reality-checking in it. Happy reading!
