I had a similar thing, but without going full Keto. I still have pasta, potatoes and wholemeal bread for instance, but I fast 16 hours so I still have some ketosis going.

I was trying to avoid sugar (i.e. Sucrose + Fructose, except for actual fruit), and replace oils and butter with olive oil. And for breakfast/lunch (because I still want to eat a normal dinner with my family) I eat the best possible versions of those. Porridge, Greek yoghurt, fruit and nuts.
