I guess I need to stop eating red meat.

I did not. I've done plant based for brief periods a couple times in my life. I think the longest was 6 weeks. I was always hungry and there was still quite a bit of processed stuff I was eating.

I remember when beyond meat became a thing. I tried it out and it really messed my stomach up. If you look at what it's made of, there's nothing healthy about it.
