I am using fitness pal to count my calories and am running 3-4 times a week, minimum 5k each time. I was 10st 5lbs and am now 10 stone exact and have been for the last 3 weeks. Just cant shift any more. I am not sure what I am doing wrong. Any ideas? I do vary my diet and do have the odd treat but not all the time. My friends who are younger than me seem to be losing lbs every week :(
