Just a little bit of advice as a veteran. You can take it or leave it.....
I wouldn't stress about losing too much. Most people, at least 95%, have a certain amount of "bounce" weight that starts to happen at years 2-5 post op as our metabolisms start to regulate and other reasons. It's usually around 5-10%. I was at the high end of a normal BMI when I met goal, and when it happened to me, I wished I was at the lower end because my 10 pounds put me squarely back into the overweight category of BMI, which really irked me.
I know it's definitely startling to see it, though. Just keep that bounce regain in the back of your mind when you're struggling to slow it down or gain a little back. It will happen naturally after a while 😘
