Well, I can see som reasons:
Reason one: Delayed gratification.
Eating healthy meals requires a fair amount of planning ahead…having ingredients on hand, and starting the process before your already very hungry. I pride myself as an efficient cook, and it’s pretty rare I can have a (non breakfast) meal on the table in less than a half an hour after I start. Much easier to just go to Micky D’s.
AND extracting oneself from poverty requires a lot of planning. Why work hard for an education that MIGHT payoff someday, when I can do nothing and collect the dole?
AND eating healthy requires a bit of education. Education on the risks of obesity, education on what constitutes a healthy diet, etc. But since education doesn’t tend to payoff today, why bother?
Anyway, my brother is pretty much poor. There are a lot of factors, but a big one is that he doesn’t plan for the future. At all. His wife has invited me for dinner…and gone to buy the groceries to fix dinner after I arrived. When a paycheck comes in, it gets spent quickly, nothing is set aside to last untill the next check is expected. A job is chosen purely on starting salery, with no regard to benifits, nor opportunity for advancement. At one time he had at least normal ambitions…just has never had a clue as to how he might get from where he’s at to where he’d like to be.
Even many wealthy, educated people don’t recognize where thier lifestyle is leading them untill one day they are suddenly 30# overweight.
But someone who plans for the future is MUCH more likely to make lifestyle changes, and stick with it while thier wasteline fades at a glacial pace. Or to try again when that firs diet doesn’t work out.
Reason Two: Low self esteem.
In general, I think it is fair to say that low self esteem is associated with both poverty and obesity. Note that the causal direction of this corilation could be either or both directions. Being either poor or fat can lead to low self esteem, which could easilly lead to the other condition, which could then lead to even lower self esteem.
There are some proud poor folk…and I’m pretty sure they are NOT as likely to be obese as those that are proud only of thier ability to game the welfare system. Strictly an opinion there.
Reason Three: Exercise
Ghettos are not safe areas to run. Gym membership isn’t free. Bicycles get stolen in the 'hood, and carrying it up the stairs (cause the slum lord won’t fix the lift) to your fith floor apartment every time you go in and out is a bitch.
Basketball hoops seem to be available. and popular in Ghetto areas. Used by youth who are not at all obese. Once they outgrow that, though, there aren’t many other options.
