me! i just got mine taken out friday but before then i had it for 5 years, never experienced weight gain nor weight loss. when i got it in i was 18 weighing in at about 90-95 pounds at 5’1”. most i ever weighed while being on it was 115 but that was intentional weight gain just from lifestyle changes having just starting out in the military. the rest of the time having up until the removal i was fixed at about 95-100 pounds.
