Then I retrained, into computers and IT, a year later I was weighing in about 80kg (176lbs). I travelled off and on for years, when I travelled I typically lost weight (carrying a pack, walking, harder to get snack, particularly decent chocolate and cheese).
After my last 6 month solo trip through South America (a part of the world not know for its high quality chocolate or dairy products) - I weighed about 90kg (198lbs). I was 30 years old. I considered myself obese (or the record at the time of writing 90kg is my aim!).
Living by myself with a sedentary job I combined lots of snacking, with some good cooking, to end up at 95kg (209lbs) after a few years.
Moving in with my partner just made mine (and his) weight issues worse. Even though we were doing competitive ballroom dancing, and dancing flat out 4 or 5 nights a week for several hours, we put on weight.
