I had surgery 1/21. I lost 13 lbs in the first 5 days but then in the past week or so I have actually GAINED 4 lbs. I'm still on thick liquids- mostly pureed soups (not cream based) and beans. I have had some guacamole mixed in with thinned beans but not every day. No juices, regular milk or anything with over 3gm of sugar per serving. I estimated calories a few days and I figure I'm getting 600-700 calories on most days. Compared to how I used to eat (at least 700 calories per MEAL), why would I not be dropping weight?
