I was somewhere around 200g protein, 120g fat, 30-40g carbs.

I replaced peanut butter with almond butter.

What about fiber supplements? Any of you guys use fiber? That's the only thing that was an unknown for me, because fiber is carbs, and I was taking a fiber supplement every day. I wasn't sure if that could somehow interfere with ketosis.

The way I can describe how I felt is that it felt like I was stuck in the preliminary stage of entering ketosis. After a few days I felt great, I was in ketosis.. but after a couple weeks it felt like I wasn't quite in keto anymore and couldn't seem to get into it.

Perhaps the carb/cheat meal once a week threw things off as well. If I do the diet again, I'm not going to bother with the cheat meal, or if I do I'll have to get some advice how to do it better so that I only get the carbs I need without going overboard.
