I can't answer what the weight loss is on 790 because I am doing SS. It's only day 9 for me but I just wanted to say that SS might seem a bit scary and over the top but trust me once you get into ketosis, normally around day 4, it' a piece of cake. You just have to get through the first few days and after that kind of plain sailing.....
Just wanted to share my views on SS as I was a bit apprehensive at first but it's worked out fine.
Not sure if this is any help t o you at all.....so i'm going to stop going on
Good luck with whichever one you decide to do!!!!!
