I have been on Slimming World for 4 weeks now, the first 2 weeks I lost 4lb a week, the 3rd week I STS and this week I have actually gained a 1lb. I haven't cheated once, I do mainly red days with the occasional EE or green. I always have about 10-15 syns. The only thing that has changed is I have started running in the last 2 weeks I have been 3 times a week for 3 miles a time and also bike riding 10 miles twice a week. Is this the reason thag I haven't lost weight as my clothes are looser and I feel a lot better I just feel so bad that the scales don't reflect this as my friend who cheats and doesn't exercise is losing far more weight! I feel like giving up! Is there anything I am doing wrong? Any advice woukd be appreciated tia.
