Gained weight 4 years after surgery
Yes, there are many people just like you. I would suggest that you post this on the VSG maintenance group and speak with the VETS that have had to lose the gain and have been successful. The bottom line, is that you need to go back to basics and start journaling your food and eating under 800 or so calories. They will share strategies as to how to make that happen. For me, I go back to eating dense protein and veggies more or less exclusively. I also eat my homemade soup like it's going out of style. I keep my liquids way up move more.
Just go to my profile and it is in the archives. It has saved me countless times and was my absolute go to food all through weight loss. I am now committed to loosing about three pounds, and guess what I am going to be eating for the next week. :)
Hopefully this will provide some inspiration:
You did it once, you can do it again!
