Engine 2

Pat read somewhere about the Engine 2 diet, created by a firefighter in Austin, TX. I got the book and started reading it a couple of days ago.
I have no doubt anyone would lose weight and drop their cholesterol significantly while on this diet. While my cholesterol is fine, I could certainly stand to lose a few pounds.
This is a four week diet and you can go one of two ways, drop things a week at a time or do it all at once. Week one you stop eating all dairy and processed foods, white bread, pasta, etc. I could do that. Week two you just stop eating all eggs, meat, poultry and fish. I guess I could do that. Week three you stop eating any type of oil, butter, etc. If you go the hard core route you stop eating all of this stuff - cold turkey, so to speak. So I'm thinking - if I cut out bread in week one, what the hell am I gonna put butter on?
I start thinking maybe I could do this for four weeks. Then I got to the kicker. No coffee, no alcohol. Wait a tick! No wine, no coffee? I know for a fact that I would drop probably 10 pounds if I quit drinking wine, but I drink my coffee black, so what's the harm there?
This diet sounds very much like a vegan diet and I don't think I could hack that. The recipes in the book do look very tasty, so maybe I'll make a few here and there and start in very slowly. Or not at all.
