The Celiac Disease Diet as well as any other fad/trend/crash diet are not a good idea unless advised by your doctor. Your best bet would be to skip the fad/trend/crash diets and slowly lose weight with proper diet and exercise.

Celiac disease usually means you will need a gluten free diet. Sites such as the Mayo Clinic will offer some insight on a proper gluten free diet for someone with celiac disease.
Celiac Disease
Yes, if you have Celiac Disease.
Celiac Disease to treat it with a gf diet.
If you're asking if drinking diet coke is linked to celiac disease then the answer is no. But if you're asking if you can drink diet coke with celiac disease that depends how sensitive you are. Most people can have diet coke but the ingredient, caramel color, can affect some people if they are very sensitive. I personally get a reaction but I am highly sensitive so you should be fine.
By going on a gluten free diet
You can't get rid of celiac disease. But if you go on a gluten-free diet, then you wan't get as sick. I should know; I have had Celiac for 7 years now. Sorta sucks but it's life.
There isn't anytime where you can know how long your going to live. Celiac Disease is not like cancer and you can die from it. Its like a healthy diet.
If you have celiac disease it's forever
If you meant "Celiac" as in Celiac Disease, you need to be on a gluten-free diet and must avoid wheat, barley, rye and oats.
There are many sites that offer you diets for people with celiac disease. This is a disease of the colon. Gluten free diet is one of the best diets available that helps with the pain.
