Leisure time is squandered by all social classes on things other than exercise. But in my rural area, the fat is well distributed. Wealthy and poor alike do a lot of work outside. As for diet, a pound of decent cheddar is $3 or 4 and cheaper than a pound of little debbie's oatmeal pies. The whole grain breads don't cost much more than the refined flour breads. The fruit is super cheap at the flea market where I and many non-wealthy people shop.
You'd be surprised to learn that in this instance, the oatmeal pies are much better for you. Chedder cheese is typically 5/7 fat. It's horrible for you.
