I am not full-time carnivore; I cycle through various eating regimens and happen to be in carnivore now. For me, carnivore is only grass-fed meat and wild-caught fish, mostly salmon. No dairy, and fruit and veg are eaten only as condiments with meat.
I do not see it as boring. I get fulfillment from other areas of life, and do not need an endorphin boost from eating food. If you want the food to taste better, try adding a little horseradish or mustard or pickled ginger as a condiment. If your boredom leads to loss of appetite, that might mean it is time to fast for a while, until your appetite comes back naturally. And if none of that works for you, it might mean it is time to stop being carnivore for a while. I do not hold a carnivore diet as a moral or ideological ideal. It is a tool. There are times when it works, and when it should be used, and there are times when other eating patterns would work better to achieve various goals, at which points it should be abandoned in favor of superior alternatives.
I see a raw carnivore diet as a time of intense healing. The diet contains no fiber, which means it is very easy on the small intestine, which can be damaged by fiber for those who suffer from leaky gut syndrome. One of the big reasons I cycle through carnivore is to give my intestines a rest, and allow them to heal in the event that leaky gut symptoms are brewing. I also find it much easier to gain weight on raw carnivore than on more diverse diets, so use it as a period to bulk up. I box, lift weights, and circuit train, and will spend periods where I do not eat carnivore to get stronger and leaner, then use carnivore periods to put on muscle mass, then go through periods where I might fast for awhile (drink only water) to enjoy some of the benefits of autophagy.
This is a cycle that works well for me. Obviously, it might not work well for others, so do not just mimic it. I always treat eating patterns as an ongoing experiment with an 'N' of 1.
