Many years ago, I tried to eat only vegetarian foods for health reasons. The longer I was on that eating plan, the more health problems I had, and the more prescription drugs I took to treat those problems.
I got talked into going low-carb and cut out all grains and root vegetables and, amazingly, I lost 55 pounds and got off all the prescription drugs. I get most of my calories from meat and I have lots of energy. I would never go back to a vegetarian diet and always eat real meat, not the fake stuff.
