Carne, with that, and what cn said, there is still something to be said that he clearly loves his friend enough to be very upset about this, enough to actually get involved and not just watch, and to come here and ask for more help. that's pretty great. this friend is well on their way to diabetes, which could hurt them physically, if not kill them.
so many times I see obese people and think to myself, how did you let this happen, and why didn't anyone try to help you. at least this guy is doing something about it, like a good friend, even though somewhat misguided. I wish someone had tried to stop me before i found myself in the situation i'm in.
just sayin'.
