At over a year out, I am still losing. Yes, it is possible to eat around it, but it is MUCH harder to eat around the sleeve than it is to eat around other surgeries. The thing to remember is that after a certain amount of time, your stomach relaxes, and you will be able to eat a LOT more than you were in the beginning. This is where the REAL work comes in. If you start to eat more carbs and eat junk, it's inevitable that you WILL stop losing, and could even gain some (this has happened to me!!). The thing to remember is that "protein first" is not just for a while - it's forever. Or for as long as you want to continue to lose weight.
Be mindful too - your loss will slow down considerably after the first 6 months. You will likely go from losing 5-10 lbs a month down to about 4-5 lbs or less a month. DO NOT LET THIS DISCOURAGE YOU. It is absolutely normal and ok! This won't mean that you're "eating around your sleeve" at all - rather that your body is adjusting to it. As long as you are losing every month, you're okay!
Hope this was helpful!
