I didn't totally avoid them, but tried not to go crazy with them. I love meat cooked with onion and a little tomato into a sauce, with loads of herbs & spices. They are higher in carbs though. I never check whether I'm in ketosis or not, and that is the main thing it could affect if you had too much. In terms of calories I don't think either is particularly high, and for the losing weight side of this, it's the total calories consumed that actually makes the difference.
