I have reservations about nailing causes of obesity to a single source. If the marketing of fatty food products does get through ones BS filters then I'd suggest that the problem lies with the psychology of the person in question. Anyone who's seen the biggest loser and the behaviour of the shows participants would have to contend that most overweight people have some sort of emotional hang-up that hasn't yet been addressed.
So suggesting that marketing plays a negative role is true to an extent, but if the belief remains that the causes are 100% or even 50% external then the problem will continue to snow ball even further than it already has.
America, a new study suggests, wastes 40% of its food supply annually. Published in the Public Library of Science, the research indicates a dramatic increase over the last decades, up from 28% in 1974.
This number, however, is not what it seems.
To understand this percentage, you have to first look at what it intends to calculate.
It does not represent the amount of food that makes it into our refrigerators and pantries only to end up in the garbage. This waste is usually estimated to be closer to 27 % of all food available for consumption, or about one pound per person per day

I've worked in some pretty shitty jobs over the years and one involved working at a tip, the other involved working at a very well known hotel chain and I've seen what gets wasted. So I'd tend to agree with these figures.
Never thought of it like that before.
