I've been doing Extra Easy and have so far lost 14lbs. I fancy giving the red or green days a go to see if they speed up the weight loss a bit, but don't really 'get' them/. I was new to SW when I started EE. My class is huge and the woman never really has time and basically told me EE would be best and I've never queried it. Has anyone got a minute to give me a brief idiots guide to Red and Green days please?
