I think boredom is a very misapplied word when it comes to lots of things. I've thought that a long time about eating and I heard someone explain how people misapply the word when it comes to their relationships too.
I always had a feeling of missing the old food. There might be a delicious steak sitting in front of me but where was the potato, bread, and everything else I couldn't eat. Was it really boring? Or was I just feeling a longing for things I once ate all the time?
The whole notion of "never again" was also very difficult to grapple with. I went through a phase where I thought, "there's nothing left to eat", which was utter BS. If I had eight spices, eight varieties of meat and eight vegetables I could have 512 different combinations of flavors and experiences. In reality, I have access to loads more than that, plus eggs, lemons, and a wide assortment of other things.
So what I decided to do was adjust my thinking. I simply had to replace the old things which I had been accustomed to eating, with new things. Things that would become as comforting and as familiar as the potato and the bread.
So I did! I found that much SE Asian food can be prepared low carb, dairy free, and gluten free, plus I love Thai food. So I bought a
great Thai cookbook, with easy to make recipes, and started making lots of curries, salads and so on. I serve them on kelp noodles, cauliflower rice, or steamed broccoli.
I make myself low carb desserts from time to time. Infrequently nowadays, but more often when I was transitioning. I experimented with sweet omelets, I learned to make crepes from eggs and filled them with LC lemon custard and a few raspberries. I made bowl muffins from low carb things, brownies, cheesecake and all sorts of other stuff.
Anyway, it worked. I transitioned from thinking of my food as "boring" to having it replace the potato and bread. As before, in my potato and bread days, I can eat the same food for many days on end and never describe it as boring, because it never was boring. It just wasn't what I was most familiar with and what I was missing the most.
I bet when it comes right down to it, you don't eat with all that when you eat high carb. People get into patterns with their eating: Cereal at breakfast, sandwich at lunch, meat at dinner. Oh, the breakfast cereal might vary slightly, the meat in the sandwich might, but basically it is the same all the time. Why doesn't it feel boring to them when they do the same thing with LC? Because boring was never really the issue, it was because they were missing or longing for the comfort of the old foods.
One other observation. Ketosis can be responsible for making your appetite diminish at first. So you sit down to eat and you have no real appetite for what is in front of you. Just increase your carbs a bit and that should go away. I'd do it by eating more veggies or some LC fruits (berries). Appetite is the best sauce. I'd also suggest trying Intermittent Fasting... when I was doing that my enjoyment of food was increased a thousand-fold.
