Struggling

Hi, I have never seriously dieted in my life. I am 53 and have always led an active life, so generally I used to be able to eat what I liked. Unfortunately U now seem to pile on the pounds, a bad back and less exercise has left me the heaviest I ever was and I am struggling to stay disciplined and motivated. We have a small holding and a riding school, so I am still active, but feeling sluggish and down. Hope to find some support and encouragement here. X
