My partner, a 71 year old, has been on a 2-month meatless diet. He has had 2 heart attacks. He feels great now. He watched this video: https://www.youtube.com/watch?v=skdRXNG8PNY. I make no other comment.
Cutting out the carbs did it for me. I’m 75 and have been on the carnivore diet four years. About four months in I noticed something was up so I asked my doc to test T at my next blood test. It came in at 521, a good number for a guy half my age.
