I have been in and out of ketosis several times the last few months while finding my maintenance routine. For no particular reason, yesterday, I wound up having canned tuna with a salad for lunch and frozen pollack with a salad for dinner. I was in ketosis this week, and doing IF, not eating after 6:00pm but yesterday evening I just really wanted to keep eating and could not get satisfied. Thinking about it, I realized I got much less fat from the two fish meals than I have been eating and think that must be related. During weight loss, I had lots of days eating tuna or fish, i.e. low fat, without that reaction, but I was not checking and probably not in ketosis. I'm curious if others have any experience eating low fat while in ketosis. I know fat is satiating, but my question is specific to ketosis.
