Some of the recipes involve higher-carb fruits like bananas, but in general, the use of the nut flours brings most of the recipes (using your food counts book) to within the realm of possibility.
Then I saw this book and I bought it! Wow! As a birthday present I made the hazelnut brownies for my father and you'd think I had given him a new house or something. YES, these recipes are work, not something you can do with what you have on hand... HOWEVER, I can honestly say that even I liked the results of this book, and the brownies... well, you'd never know they didn't have flour in them. REALLY.
A few notes: if you're going to do the hazelnut recipes, do yourself a favor and mail order them roasted and skinned. I bought them raw at a coop and roasting and removing the skins was the most annoying part.
Second note on the brownie recipe: It can be a bit hard to get the brownies out of the pan without breaking. The second time I made them I used a springform pan and I was much happier.
If you want your friend/familymember/yourself to love you forever, I highly recommend this book!
