How many poor people eat out a lot? A ton (pun unintended). They would rather eat the 20-piece KFC bucket instead of doing what my family does, which is make macaroni, Ramen noodles and other low-cost options. I can make a turkey wrap sandwich in a soft tortilla circle-thingy for very low cost - healthy and low calorie.
No time to exercise? B.S. But they have plenty of time to spend mindless hours a day on their phone or plopped in front of a TV set.
Poor obese people are obese because they lack discipline, period...which also explains in large part why they're also poor. Quit making victims of people who are where they are by their own choices.
