I would argue that you are accidentally correct.

Yes, eating healthy is more expensive than eating fast food and microwaveable junk all the time. No, you do not need to buy a bunch of workout clothes and supplements and junk to be healthy. Those can be great enhancements for whatever your goals are in the gym, but they are certainly not necessary for living a healthy lifestyle.

Go and buy a set of running shoes and a few pairs of sweatpants, sure. I guarantee you that somebody who eats healthily and goes out for a daily run, followed by pushups and situps can be just as healthy, if not moreso, than a gym rat pumping themselves full of creatine and vitamins.
