I started back on a 4-3 diet on Sunday. I tried to do this diet last summer but after 10 weeks I was disappointed to find I hadn't lost anything. My ankles were swollen (in the hot weather) and I went to my doctor who told me that I wouldn't lose weight because of the water retention - but she wouldn't prescribe me a diuretics, so, I gave up on the diet, and put on another half stone. Now the ankle swelling's gone down, so I'll try the 5-2 (or for me 4-3) again. I really want to shed around 3 stone - has anyone else had the weight gain/water retention problem? If so, is there any proven way to get rid of excess water other than prescribed diuretics?
