Well I am not on full carnivore yet like 80% at the moment. Soon hopefully going full. I feel much better I am losing weight slowly in a healthy way. More satisfied with the food. I have more energy. Red meat gives you all the necessary stuff you need. It will not get boring because you can make a lot of different stuff. You can mix some veggies or fruit in your diet along with meat from time to time but try to buy 100% organic. I try to get it from small farms around my city. Cut out seed oils, use butter, beef tallow or extra virgin olive oil. That will help also. 

 Also carnivore is not eating only meat, you eat everything that comes from animals: eggs, milk, cheese, cream cheese etc
