Your Weight May Change
Regardless of whether you start out underweight or overweight, your weight likely will trend toward normal levels once you're diagnosed with celiac disease.And being following gluten free diet.

While many people think all new celiacs are underweight, studies have shown that most are a normal weight, while many are overweight. For example, one study found about 61% of newly diagnosed celiacs were considered normal weight, 17% were underweight for their height, and 22% were overweight or obese.

Following their diagnoses, the underweight patients tended to gain weight, while the overweight and obese patients tended to lose weight. The normal weight celiacs tended to stay at a normal weight.

Therefore, if you're overweight or underweight at diagnosis, you can expect to see your weight tend to normalize as a side effect of the gluten-free diet. However, if you indulge in too many gluten-free snack foods (which tend to be high in calories and low in nutrition), you could find yourself packing on a few unwanted pounds. So be careful.
