I totally get this and can relate. I have a sister who had the sleeve done six years ago. She continually talks about how I eat more than she ever ate at this point. She said she lost it a lot faster. Most of the family thinks she is unhealthy and doesn't get her Protein in.
I had my sleeve done on July 8, 2014. I have lost 29.1 lbs so far. I am excited about my progress, but she does make it hard. On the other hand, I have two other sisters who are super supportive and say nice things.
Stay positive and remember we are all different!
