I've lost about the same amount but have since regained about 12kg and have been sitting about 7kg more than I would like for some time.
I've been asked what I did to lose weight but I really don't have a good answer for it. At a couple points in my life I've decided to take dieting very seriously. "ZERO cheating" works when you are serious. Other times I've started "seriously" and the eventual work party, birthday, vacation, etc throws me off and I lose motivation.
I wish I could tell someone what I did to make the mindset change necessary to diet seriously, but I can't figure it out myself.
I am in the same situation: Roughly at a time where I moved to a new house I decided to loose weight (133kg). In 2.5 years I lost 40kg, for 6 months I stayed in a plateau, then in the next year I regained 20. Since two years my weight is more or less stable.
Today I am, like you, not sure why I loose so much weight, why I had a plateau, then why my weight went up again.
