For 10 days I went without meat, milk, and eggs completely. The first few days, I kept feeling better and was like, man I'm going to do this forever. After that, I started feeling colder and noticing I was skinnier. It got worse each day. I checked the scale and saw that I had lost 7 lbs, mostly muscle by the looks of it, so I aborted the mission. I know vegans say they can get plenty of protein from beans and rice and grains and vegetables. Believe me, I ate a shit ton of all that stuff. Now, from personal experience, I am convinced that people are supposed to be omnivores and I'm not going to try to change that.
