I can't work this one out!!! I weigh 10st 3 and am trying to get down to 9st 7 or less (I'm 5 ft 7 tall).

The strange thing is that I've upped my exercise to swimming 5 times a week for 40 mins. I also go into the steam room afterwards for about 20 mins. I have decreased my eating and yet in the last 2 weeks I have gone from 9stone 13 to 10st 3!!! Why have I put on weight???

I drink a large glass of red wine each night but have always done that so I just can't understand why I've put on weight?

Any suggestions would be greatly appreciated
