Its a book over here in germany called "Schlank im Schlaf" by Dr. Pape, what pretty much means slim while sleeping, its pretty easy to understand, like dont eat stuff your body needs to work on at night much so you burn fat during the night...
I dont have the book here anymore to explain what it exactly does but it works pretty well (for me at least).
The only things you really have to go with is that you NEED to eat (in my weigh class) 100g carbs in the morning with bread sweet jam whatever but no animal stuff so no cheese sausage eggs and such..the other important thing is to not eat inbetween so your bloodsugar or pressure (im not sure) can get the time to start new with each meal. It says it also works without workout but..I dunno about that :P
Anyhow for me it works out really good and its not really a diet its more like a lifestyle and I live it well.
The only thing is that starting that "lifestyle" I also became an vegetarian (I still eat fish tho just no meal, dunno what else you call it) so my meals get a lil one sided, but I feel much better without meat for whatever reason.
Hope you didnt get all confused now.
And thank you!
