Blaming society sounds fatalistic, but yes we absolutely can change society. There are mechanisms to do it, and the first step to utilizing any of them is people getting pissed off about the state of things and talking to other people about how pissed off they are about it.
I promise you if ground beef is all you eat you will be much worse than fat and out of shape.
You could try it for say, two weeks. I’ve done it for two years, so nothing super crazy can happen in two weeks.
Even in that place you can do better than ground beef.
Get an instant pot and invest in some rudimentary cooking skills. I’ve spent a whole year making variations on the same dish in 15 minutes, using that cooking as end-of-day stress relief. Shopping for the same handful of things once a week.
It wasn’t fine dining but it was healthy, cheap, and a few steps up from ground beef. Come now.
Yes, all the processed grains and seed oils and artificial sweeteners and chemicals should never have been invented. But I’m not too fussed about that. What I can do is come here and write these comments about the diet that changed my life for the better. If only one person who reads them tries it out, I will already have succeeded.
At some point blaming society isn’t going to cut it.
