Double Calories Stink

Not big news here, but the fact that the GF equivalent of most foods contain double the calories of gluten foods just stinks. I gained 30 lbs. in 7 months when I started the diet, partly because I was absorbing food, but partly because I didn't KNOW the sneaky little calorie count. Now topping the scale at......(NO, I won't post it! LOL!) a big number, I know I need to lose weight to feel better. I suppose celery & I should get reacquainted. Any tips for a low fat, low meat protein, low sodium, low calorie, high fiber gluten free plan to lose weight?
