I'm actually amazed at the lack of constipation, and that's on the sugar water and not oil. If anything, I've been even more regular, albeit in smaller amounts.
Today I ate around 1000 cals, which amounts to a pretty strict diet, done that kind of thing in the past and could not stick with it because of hunger. The really amazing thing is that I am not even hungry, in fact I believe that I could even manage to eat less. It might not sound too amazing, but at ~300 lbs, doesn't that sound a lot better in kg ...only about 130 of those ;-) then I think just how amazing it really is.
The "acid test" is tomorrow, we're doing Father's Day a day late to enable all the kids to be there, it'll be a BBQ in the evening. I already have some pork marinating in red wine with garlic and coriander seeds (I think you call coriander ciltrano across the pond) The upside is that we will simply help ourselves, so a little of everything will be an easy way to eat enough and not go overboard.
