Hi and welcome...
Try google -ing the caeliac association, or even wheat free recipes. We had to go wheat free for my son when he was little, and those recipes made a HUGE difference. I don't knwo about England, but in Australia you can get 'Spelt' breads and flours which is a good substitute.
Good luck, it's very doable, and quite honestly dropping wheat out of your diet should actually assist in your weight loss.
