For most type 2s, porridge made with oats is too carby. Some people can manage it, but not many. If you have a meter, you could experiment a little to see your individual reaction to it. Failing that, that are various mixes of chia seeds, flax seeds, etc, that people put together and call keto porridge - you could try to see if any of those work for you.
My new breakfast is a mix of milled flaxseed and chia seeds, 2 spoons flaxseed to 1 of chia, add a little salt and some cinnamon and a few chopped seeds or nuts. Add water and microwave for 2mins, then add a spoon of coconut milk, plus a little erythritol if you need sweetener and serve with double cream.
