Honestly, if you have to eat ketogenic, you do need to know you are probably starving the gut bugs that give you health and well being. You don’t have to be. Just make sure your few carbs are their food and you aren’t missing out on anything nutritious.
In my opinion, once you don’t have a seizure disorder or severe mental illness or obesity, you don’t need to stay in actual ketosis 24/7. Just eat low or very low carbs and make sure there is plenty of resistant starch for the gut bugs. They don’t need much.
I do eat probiotics, like sauerkraut and kimchi as part of my diet.
