It's all fun and games till you get health problems. I should eat something else, but I get super nervous whenever someone suggests I eat a new food. I do cook some potatoes once a month tho.
You can maybe diversify a bit by adding other stuff while leaving the base the same.
E.g. my go to is oat meal. But you can add apples, bananas, nuts, strawberries, seeds, etc. This should combat the one dimensionality of that lifestyle a bit. At least I hope so, lol.
