All the cheap food in the US is bad for you, or at least 95% of it is and it is also faster than making healthy food. Although making a boat load of chicken or pork for a week is not incredibly hard or expensive, but people choose not to walk, never work out, and have horrible portion control. Also BMI is pretty dumb for body fat specifically, in general it probably evens out, but you need grab the tape measure and take a real test or do one of those fancy machines or whatever they use, if anyone has stories on using those I would be interested.
