Over the years, this is the third or fourth version of this same story that I've read.
Read one on low carbs. Read one on low fat. Now this one.
The assumption here, as it was in the others, is that we now know what works and what doesn't. And that forces beyond our control conspire to keep us fat. In this version, the thesis is that some form of certification system for marketing to children can cure the obesity epidemic.
Beats me. But I'll bet twenty bucks that a decade or two from now we'll be reading the same type of article, only with different kinds of suggested cures.
I'm of the opinion that there is nothing wrong, or rather that the population is acting entirely naturally and appropriately given their adaptation to specific evolutionary conditions, which have changed drastically in the last 100 years. I doubt controlling marketing material will have a long-lasting effect, but anything is worth a shot. It is a very serious problem.
Looking at the recent past, I'd be just a bit more humble about it.
