A work colleague has been using it for a little while and yes, he was a little overweight when he started, he now looks a little underweight, gaunt and pale.
I am overweight, I've adjusted aspects of eating, exercise and lifestyle to lose some and I have, over time, but obviously the WLI was of interest to me because I've still got more to lose so I asked him about it.
I don't really know the ins and outs because he's really focused on the fact he now feels he has control over binge eating, that because he has no appetite now he feels free from something that made him miserable, and he's worried to stop taking it and go back to feeling like food rules his life, and I can totally relate to that. However I do feel that he's gone a bit too far the other way, maybe because it's happened so quickly and the contrast is stark, and I do think that continuing would risk him being more and more underweight and the issues that brings too.
It's very easy for people to write me off as jealous of him because he's lost weight quickly and I haven't, and I definitely think there is an element of jealousy for some people, but I'm concerned that actually all it's done for him, and all it would do for me, is enable a continuation of a bad relationship with food because of issues with self esteem which I suspect he has, as I have, linked to being overweight, and feeling like losing that weight will solve those problems when actually I don't think it will.
It's a great idea for people who are overweight and I don't see it as cheating, it works for people who are overweight and for health reasons need to lose it, but I don't think it solves the underlying problems some people (me included) have with self esteem and genuinely liking yourself for who you are and actually although yes, I'd lose weight on it, which is something I want to do, I'd be worried I'm setting myself up to just be under another set of control and still have a bad relationship with myself and food.
