I'm seeing something similar; about 18 months ago I started walking to and from work (4 miles) and started cutting out sugary drinks. I went from 325 lbs to 270 lbs in just over a year, but the last 6 months I've barely lost any weight, strangely enough though my body shape has still been changing for the better, as it's only in the last 3 months or so I've dropped another trouser size.
