If that's the case, then your initial statement can't be true.
I would say this, these threads come down to 2 sides, real life experience vs internet know-it-alls and other assorted folks who mean well but never had a weight problem in their life (ie, don't know what in the 9 hells they are talking about), and I don't know about you but most internet know-it-alls I've encountered couldn't find their d!ck with 2 hands and a map. The amusement works both ways.
