It's amazing how much food you have to eat when you're a vegetarian. I went vegetarian for about a year. After my first month I felt like I was dying.

I was a banker mason for 10 years before going back to university, carving stone almost every day for years, I went vegan 5 years in and I didn't experience a sudden drop in energy, I made sure I was getting enough protein and adequate amounts of vitamins (especially b12) either through food groups of vitamins tablets.
Also after not eating beef I haven't lost any muscle mass, I may be crazy but I think big beef has been lying for decades.
