So glad I found this forum. I had lost down to 93 lbs. by the time I received my final diagnosis of celiac. I am 5'3" and 67 years old, so that wasn't good. I, too, used to eat large amounts of food and not gain. Now I've been gluten-free a month and I seem to want to eat all the time, especially rice cakes (used to eat lots of bread & bagels before). I've gain 4 lbs in this one month period. So as mentioned ina previous reply, I'm going to stick to meat, fish, eggs, fruit & veggies & occasionally ice cream. Oh, I do eat cheese and yougert.
