You are a winner!
There is one common marketing strategy that works really well that serves to make people fat and die young. Make them a winner for being a glutton.
You undoubtedly have seen that appalling TV show that has people competing against each other in races to eat the most of a particular thing, like burgers, pork pies or pickled goats brains or wotnot.
They even put a disclaimer on the show, "don't try this at home, these are professional eaters." What on earth is a "professional eater" anyway?
One can only wonder if TV networks in countries like Eritrea and Ethiopia would ever show such an abomination to their viewing audience?
Here's the other thing. Restaurants that serve things like a "belly buster" - a massive plate of meat or something that if you manage to eat it all, you will get a free T-shirt, ten dollars or you get to snog the waitress or something. Regardless, successful gluttony in those establishments is greeted with prizes, fanfare, and of course, lots of free publicity in the local press for the eating establishment.
People will applaud greed. You will be a winner.
The weird thing about these winners? They usually aren't all that fat.
They will still die young though if they keep that up.
