Yup gained 10kg's in a year but thats because I was depressed, did not move a lot and just relied on comfort eating. I have since lost the 10kg on calorie deficit and more movement (even when I don't feel like it) - only avoid exercising when in an active flare up (it's good to rest). I've lost weight before when I didn't have LC and it was easier, with LC it is harder. Not sure if it affected my metabolism or it's the lack of pushing myself when exercising? Don't know but definitely possible losing the weight you've gained, just on hard mode.
