Grannie-
People gain weight after being diagnosed for two major reasons: your gut is healing, allowing you to absorb more nutrients from what you eat, and gluten free "specialty foods" can be higher in calories and/or carbohydrates.
The first question you should ask yourself whenever you can't lose "that 5lbs" is "Do I really need to lose this weight?" If you've always been small, 5lbs (even on a short frame) isn't likely to make you all of a sudden "overweight". Check your BMI (you can google BMI calculators). If it's 25 or under, you may not be losing the weight because your body doesn't want you to. 5lbs in six months is not an alarming gain for someone still adjusting to a diet.
That said, you don't want to continue gaining, either. So stick with what you know is healthy: keep up the exercise, drink plenty of water, get plenty of fruits and veggies in. Bette Hagman has at least one book on cooking light and gluten free. Also, make sure that you aren't overexercising compared to the number of calories you take in. "Starvation mode" where the metabolism slows if you don't take in enough is NOT a myth.
It is most likely that your weight will begin to stabilize soon- the first six months are where your body goes through the most changes after going GF. However if you follow all the advice above and continue to gain weight, I'd recommend having your thyroid function checked and/or meeting with a registered dietician.
