I've become a big fan of the 'food doctor', ian marber. Most of his recipes are low carb, easy to make and delicious- amazon stock all the books and I've found the reviews useful. He also sells seed mixes, bars and the like. I've found soya nuts to be a fantastic snack- filling and no impact on sugars but haven't tried any of his other products. Soya nuts are sold under the food doctor brand but I found cheaper ones in the indian food section at Tescos (can't remember the brand i'm afraid).
