I'm not saying it's hokum. I'm saying it has to do with appetite control : satiety. Potatoes literally fill you up, while other foods not so much. It is this "filling up" that leads you to eat less and lose weight. That's it.
If it really is just about filling you up, then you can do that and still get enough protein and fats to do this indefinitely. Even by eating potatoes in the mix.
Don't you find it interesting how people have latched on to potatoes as some sort of weight loss talisman? It's as if I am attacking their religion here, when all I said was I intended to find out whether there was anything to it.
If you really want to discredit me and don't care how you go about it, there are better ways than just taking my replies out of context
