Kathy, congrats on your surgery! It is my understanding that, even if we eat JUNK, the pounds will still melt off during the first 6 months. (The bad news is that they won't *stay off* if we don't change our eating habits.) During the first few weeks ESPECIALLY, it doesn't hurt to eat tiny portions high in carbs in order to get your liquids in, or even the soft food diet that your doctor orders. I am 6 weeks out and have lost 35 lbs, and have yet to experience "ketosis," as far as I know. I'm trying to limit my carbs to 40-50g per day, get in all of my protein, and avoid those sugars. I eat around 600 calories per day. The scale keeps moving down, so I'm not too worried that I'm doing anything wrong. Good luck to you, Kathy! I'm sure you'll do awesome.
