It would be easy for me to be out of shape. I was a fat kid because I grew up in a poor rural area where health literacy is low and the rates of obesity are high. I stayed fat as an adult because I was too busy to exercise regularly.
I did not prioritize my health. We have to put in a lot of work to find resources. The list goes on. Your reasons are valid, but they are still bullshit.
It doesn’t have to be expensive to have healthy food. If the fresh stuff is expensive, look at the canned and frozen sections. It is better to buy canned or frozen produce when it is out of season because the quality is higher and the cost is less.
