Fat burning furnace: does it work for you?

Hi!
I purchased the ebook a few months ago, gave it a try, didn't work (maybe I wasn't doing it right), and I'm wondering if anyone else got it (I notice its advertised on mfp) and if it works for you, cause I'm starting to contemplate it again...
I'm asking, because it goes against a lot of what I knew about nutrition and working out, so I'm wondering if I've been had :grumble: or if it could really work if I do it right...
