Welcome to the site
Many of us have experienced a weight gain. Its great that you have reached out and working on getting it back down.
Pouch reset is going back to liquids and progressing back out to real food stage. (It does not shrink your pouch) It may help you feel your restriction a bit. Its one way to help get back to healthy behaviors. Another option is to start at real food stage if you feel reset is too restrictive.
Some choose to change diet plans Keto, paleo, vegetarian,IF, whole 30 etc. Only my opinion. Whatever diet you choose, The key is logging your food in an app and staying with in your weight loss calories/macros. Basics: Food plan, exercise, hydrate
You know what to do but it may be difficult to get your head back in the game. A few threads on the site that may help.
