      Don’t forget also that meat products need to be fed calories before you get calories back from them. Look up trophic levels if you want more info, but I believe the rule of thumb is 10x the amount of calories needed for most meat products.

      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. Simple things like putting on my shoes left me exhausted. I finally started using a calorie calculator and discovered I was getting about a thousand less calories per day than I actually needed.

        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.
