Starting from January, 2010, finally finding my resolve and going completely gluten, dairy, sugar, evil free I lost about 20lbs (9kg). Then, since switching to low carb in April of this year, I've lost another 20. All in all, I've dropped 40lbs (18kg) in 2 years - from 220 down to 180. :D
I could still stand to lose a bit more fat, although I feel like my 'weight' is fine. I've been exercising lately which seems to be bringing another burst, this time more in body composition than in actual weight loss. I just seem to have more definition than previously. I think it's the best shape I've ever been in, and I feel like there's more to come!
