Hi anchor,
It's just before bed and I just happen to spot your thread/post and read, and though I'm yet to see the commerical you spoke of and not yet ready to check it out, all I can say, is that about 2wks. ago I read a series of articles in the Australian news about far, far too, too many people drinking themselves stupid. I mean that was literally one of many News headlines. The articles were all about booze and resulting brain damage,
......and so my guess is perhaps a contributing factor to the overweight dilemma that you mention here is BEER

. Bottle upon bottle, Cases upon cases, kegs upon kegs, and all routine and spread out over an extended period of time. That could certainly do it.
That commercial could just as well be here in the US, because the overweight population is everywhere here too.
For a matter of fact, one of the things that impressed me about the Australian articles on drinking was the direct link to and discussion of (I think it was thousand's of people) with alcohol brain damage and in need of services; plus, the need for greater services and treatment regarding this.
I wondered why, I had never once read, viewed or heard anything about this link and discussion of it anywhere around here. I mean, the city I live in (though it's not much of a city IMO), is known and rampant with heavy, chronic drinking(ers), and so it seems to be everywhere else, as well.
Hope
