Well for starters, i live in the second fattest state (apparently) and really, id say only about 1 out of 6 of us are over weight, not even obese really.
i say people blow this shit out of proportion.
secondly there is no clear threshold for overweight or obese, and really, they seem to raise the standards each year.
Thirdly the BMI (Body Mass Index) is flawed as shit. dont take my word for it.

Fourthly, means the healthier people have an advantage and fat people wont breed as much. *evil grin*
But, what makes foods fat isnt 'preservatives'(salts are worse, but i digress) its over eating without burning calories to off set it.
So if i may make a suggestion, dont eat potato products or anything with alot of sodium, once a week is a good limit, eat meats and deli sandwiches and just go for a light stroll or bike ride around the neighborhood and drink LOTS of water and eat sensible proportions. Example, one sandwich is a meal, dont use mayo and drink skim milk(skim milk is possibly the healthiest thing to ingest. Lactose-intolerant? Give over it pussy)
But the above advice wont be used because we live in a dumb down society thanks to reality television....the root of all evil.
