It's only in the last year that I've lost the idea of ever losing/maintaining weight willingly/intentionally.
Thanks to work and uni I was in positions where eating junk food became regular/mandatory occurrences so weight gain was inevitable since I never exercise (the closest thing being my job itself).
So in my case it can be argued I was pushed into gaining weight and I'm merely accepting/enjoying it where as others might panic.
That said, you may find this useful:
