Well this is a hit in the head. Lost 12# one week post op. Next 2 days, I have gained 1 1/2 #. Getting 90% of water, 100% protein, and about 500 calories what with skim milk and protein mix. Anyone else had this happen?

I'm a daily weigh-er (I know, bad, slap my hand) but I recently had a day where I gained a pound and then the next day I lost 2. I think it all evens out. With the number of calories we're taking in we're bound to loose weight.

Don't let it stress you out! Keep doing the right things and you will be fine!

I had this exact same thing happen to me this morning! I'm 30 days post-op today, and so far, I have lost weight every single day (except for the first couple of days after surgery.) All I've had for a month are Protein drinks, yogurt and a few pureed Soups - 800 calories max. So HOW did I gain 1.7 pounds this morning?????

Nobody can convince me that losing weight is as simple as calories in/calories out!

I fully expect to drop that 1.7 pounds in a day or two.......... but really, GAINING on 800 calories/day?
