I find food shopping and cooking the most difficult to do. When I can I cook a big meal and freeze the left overs for the many days i just cannot cook. My Mum also freezes her left overs and gives a few to me each week, which is a godsend. Basically, I cook about once a week. For breakfast I have oats, berries, chia, other nuts and yogurt then am full enough to have a banana or protein drink for lunch. It is dinner I can't handle.
