I havent figured out the macro ratios yet and have been trying to increase my caloric intake even though it seems impossible some days. I totally agree with your endo about gluten, but im not so sure that carb free is necessarily essential. I used to follow the rules of eating only naturally occurring sugars (nothing processed and little to no sugars added). I found that the muscle weakness and dizzy spells worsened after a short time. I avoided fruit but ate mass quantities of veggies (which aggravated the gastroparesis thanks to all the fiber xD). I would say use the site to track your calories as they are, stick with it for a few weeks and see if you feel okay or need to adjust anything. In a lot of ways, once you kill the gluten its easy to eliminate the extra carbs just because so many processed glutinous foods are carb heavy (breads and pastas). I wish you all the best luck!
