I agree with you, There is not a lot of information and support for people maintaining or have weight gain. Most vets disappear from the forums because it's mostly new people. It's hard to see people struggle with a major weight gain. I know this is not easy from my own experience.
You may not want to hear some of this. But, I'm saying it because I care.
The work does not end after goal. Don't let this gain become 100+ pounds back. Are you willing to change, work and do things that are not convenient or comfortable? Suffer the pain of discipline or the pain of regret.
(1) As you progress out from sleeve surgery your restriction is less. You will be able to eat more food.
(2) Stretching is rare. Very few revisions are done. You can make an appointment with your surgeon to see if you stretched your sleeve. Ask your dietician/surgeons office for help getting your diet back on track.
(3) Many people confuse stretching for the the ability to eat more and grazing food throughout the day (combinations of health and unhealthy foods) Any of us can eat around our surgery. Eating more calories is causing the weight gain.
(4) Pouch reset is a fancy way of saying getting back on track. Pouch reset is the old diet progression (liquid ,soft foods then real food stage) If you find this too restrictive try a different approach that is realistically sustainable for you long term. Contact your dietician or research diet options.
(5) . Portion control/surgery restriction will only take you so far. To set your body back into weight loss mode is to know how many calories you are eating. You can use a food app. It makes it easier. Click the link below.
