Can anyone shed some light on this? I have begun to exercise, walking 40 minutes at fast pace morning and evening, every day. I am eating the same but since I begun - 4 weeks ago - I have put on 5 pounds. I also have a hectic day - teaching special needs kids which is physically tiring and mum to 3 kids under 6 so I'm constantly on the go. Its all a bit demoralising really!! Any advice?
