I lost around the same amount about 2012, then gained 10kg/22lbs back as soon as I started earning enough to not worry about rent and medical costs every single time I went grocery shopping. Good for you - wish I could have been so disciplined (though 40lbs still isn't that bad when everything is said and done)
