yes. This is the first time in my adult life that I've actually been able to maintain a loss (I'm five years out and have been in maintenance for 3.5 years)
not gonna lie - it's a daily struggle - I still plan my eating for the day every morning (or the night before), log my food intake, and try to stay within my maintenance calorie range (which for me is 1500-1700 per day - but that's going to vary for everyone). It's a hassle but it's do-able. I NEVER could maintain a weight loss before I had WLS.
I should add that most of us gain 10-20 lbs after we hit our lowest weight. It's not inevitable, but it seems to happen to the majority, for whatever reason. I shot up 12 lbs in year 3, and then another eight pounds last summer & fall (I'm in the process of dealing with the recent eight-lb gain. I have no desire to go back to my lowest weight, which I think was too low for me). But keeping the weight off is do-able if you monitor yourself and, as someone above said, see this as your new lifestyle rather than another diet.
