Hi lifesalaugh
I have Celiac's (and also my son) as well. I've found that even eating healthy, the substitutions for wheat are higher in calories that the wheat version. My solution has been to just get rid of any kinds of baked goods or gluten free breads or crackers. Rice flour, potato starch, tapioca starch and bean flours are higher calorie that wheat. The only thing I miss is good old Fiber One cereal!
Try to get you nourishment from whole foods: Fruit, vegetables, lean meats, fish, healthy fats. You can be overweight and malnourished. Another possibility is that now your gut is healing and you are absorbing the nutrients (and calories) in what you eat and it's just too many or way more than your body was used to when everything went through you.
How are you doing in terms of the Celiacs? Has a gluten free diet helped you?
We have good days and bad days still, and it's been almost a year and a half. It's tough- but with all the new media exposure, at least more people are aware and labeling is getting better.
Feel free to PM me if you need any help.
