Hi @missstephyl, Welcome to Connect. I haven't had the weight loss surgery but thought about it when I was up to 330+ in my 50s. I've struggled with weight my entire adult life and it's only been the past few years that I've been able to get down to a comfortable weight for me and maintain it. I have been between able to maintain my weight between 210 and 220 now for well over a year and I attribute it to intermittent fasting (daily time-restricted fasting - eat normally but only within an eight-hour window each day). I alternate between an 8, 6 or 4 hour eating window based on how I'm doing with my weight. I'm still thinking of trying to lose an additional 10 pounds but haven't really started working on it yet.

There is a discussion you might find helpful if you want to give it a try.
