stuck at 55 lbs lost

I am 4 months out from having the sleeve surgery done.  I have lost about 55lbs and can't seem to get past that.  It has been several weeks now and I keep gaining a lb. or two and loosing a lb. or two but can't budge from that.  Need help and suggestions.  Is this normal?

How much water are you drinking?  How much protein are you getting in per day?  Are you tracking everything you eat?  Are you exercising?

All of this!

13lbs a month seems pretty good to me!!  Loss is often not steady. Many oeople find they lose a chunk, stall for a while, lose again.

I am almost 8 months post op for the sleeve. I have had this happen several times. As soon as I take my focus off the scale the weight starts to come off again. Like you I ensure I get the protein in and exercise but now I am toggling between 200 lbs and 202lbs. I am so ready for my weight to be below 200 lbs. I won't complain because I am down 75lbs since January. My advice have patience with yourself. It will start coming off again. 

You're not stuck, you're stalled.  It's totally normal!!!  You'll body is just taking a little break to catch up.  Breathe, keeping doing what you're doing, and stay off the scale for a while -- like a month.  :-)
