I struggle with activity when I focus on "exercise", but if I do things like projects around the house, gardening, or other things that are not necessarily an exercise, I do better. being active doesn't have to mean training for a marathon or going to a gym. Moving your body is what is most important.
As far as food, I don't have the same struggles with it anymore. I cannot pinpoint when it actually changed for me, but I know that at some point in the last year, I realized that I just don't struggle with using it emotionally or being addicted to it any longer. That is not to say I never eat too much or get a craving for something in particular, but it seems much more the way that my friends that are naturally thin eaters crave something and I can eat a bite or two and be completely satisfied.
