Poverty and obesity are two issues that I'm really interested in. The two don't always go hand in hand. When I visited Nepal, which is one of the poorest nations on earth, I never saw an obese person the whole time I was there (I saw a few overweight climbers, but they were from other richer countries). In fact, most Nepali people are slim or even skinny, even those who are athletic mountain climbers. Some of the tiniest people were the porters who carry heavy loads up and down the mountains. I had to look closely at the porters because otherwise I would have assumed they were young girls or boys not old enough to be doing such work.
I suspect the obesity epidemic in the U.S. and similar places is more complicated than just blaming it on poverty.
Gee, I hope I have made clear in my previous posts on this thread that in no way do I "just blame" the obesity epidemic on poverty. And yes, it's clearly much more complicated than that.
As I have tried to explain, there are all kinds of factors in modern American life that cause obesity -- scientists themselves are nowhere near sorting it all out. But logically, it would include everything from the easy availability of cheap junk food to the increasingly sedentary nature of American's lives, from the promotion of dirt-cheap high-fructose corn syrup, to the car culture and growth of suburbs that all but prohibit a car-free existence, to the increase in what we consider "ordinary" serving sizes after McDonald's realized it could make more money by supersizing things (when french fries were all one smallish size, people wouldn't buy two because that seemed piggy, but they wouldn't hesitate to buy bigger sizes), and on and on and on. There are probably dozens or hundreds of factors, affecting Americans at every socioeconomic level.
All I said was that people in poor neighborhoods are more effected by some -- not all! -- of those factors than are people from wealthier neighborhoods. So statistically speaking, poor people are heavier than rich people. That's in the U.S.
(And by the way, there are other breakdowns: suburban dwellers tend to be heavier than city dwellers. Again, that's a correlation, not a causation, and one can imagine a number of reasons for it. But one likely one is that city people can walk to things more easily, and suburbanites tend to drive everywhere. And yes, that somewhat negates what I said earlier, because on the other hand suburbanites often have nice walking/biking paths and city people may be afraid to walk in their neighborhoods. So, as I said, it's complicated!)
The reason that's not the case in Nepal is similar to the reason that it wasn't the case in the U.S. or anywhere else until the past half century or less. Because those factors -- especially the easy availability of cheap junk food and sedentary car-oriented lifestyles -- are not common in Nepal, nor most other poor countries. My point was that throughout all of human history, until the past 50 years in the U.S., the poor as a group tended to be thinner than the rich. Now the reverse is true. In this country. (I don't even think it's the case in Europe -- in my observation as a visitor, Europeans are thinner, more active and lighter eaters.)
In contrast, groceries have a hard time even giving away whole chickens. A whole chicken costs less than $3.50 but who has the room to store it, the patience to cook and debone it, or the inclination to heat up their whole house with it?
My solution is to buy those chickens they roast in the store. For a couple of extra bucks, you get them already cooked. We eat the legs and wings and thighs the first night, and the second night I chop up the white meat for enchiladas or something.
I'm guessing, too, in Nepal they don't have stores on every street corner stocked with soft drinks and potato chips. 
Let alone those Super Gulps or whatever they're called!
And are people even being taught anymore how to cook a whole chicken?
To be honest, even though I arely go to the trouble myself, they're actually not that difficult. Rub them with a little oil, garlic, tarragon and lemon. Cut up some potatoes and toss them in the same thing. Arrange in a pan, add an inch or so of water, cook for a couple of hours, voila.
What I cook more often are boneless, skinless thighs and breasts. Even easier, though more expensive.
Other people like that thing where you stick a full can of beer up the chicken and then grill it, but I haven't tried that myself.
(I'm not sure about the dark-meat thing either, but I know that once my dad developed heart disease he was told not to eat the dark meat of chicken or turkey anymore. I guess it supposedly has more fat than white meat?)
Dark meat indeed has more fat. But also more flavor. I prefer dark, but some people just don't like it, fat or not.
