Hi Cassie,
I am very excited you are on the diet. Basically you can eat anything you want except the gluten and milk. There is so much to eat which is good and has plenty of calories. If you want fat then you can find it. I get a big can of nuts to snack on and they are full of fat. I look on the label to make sure they don't say "processed in a plant that also processes wheat, milk". Recently I have purchased a pound of almonds (unsalted) from a health food store, and some cranberries. I eat a lot of bananas (120 calories each), apples, oranges for breakfast. I make corn muffins to get over the "bread" issue. I love corn muffins so, for me it is a good substitute. I have a few bags of flour made from buckwheat, cornmeal, rice, tapioca, and garbonzo beans! I bake whenever I get the urge for some dry or sweet tasting food. There are also gluten free hot breakfast meals. Just watch out because while oats are OK (gluten free) they are often contaminated with gluten because they are processed in the same plant as wheat products and grown in the same fields.
I never thought I had any problems with digestion and elimination and really did not have any signs that I was gluten intolerant. I can tell you that my stool is softer and healthier for sure. I don't know if I have Celiac Disease because I have not had a biopsy done. I can tell you that my skin immediately (3 days) felt better on the diet and I am sure it was causing an unhealthy intestine.
I often will boil some chicken or fish in a big pot with some frozen vegtables until it is cooked. I will then throw in some rice to thicken it from a soup to a meal. I then store the meals in ziplock (TM) containers for the week and freeze the rest. Typically I will eat the same meal for lunch about 3 days in a row. I am still learning how much to cook because sometimes my family will eat the meal and sometimes they won't

Don't worry about low calories because even a 500 calorie loss each day equates to only a one pound loss per week. Once your body adjusts to the new diet you will find ways to even out your calories. The best part is that the veggies are much better for you than bleached-enriched flour products!
Now for some uncanny information: A lady at work recently started taking thyroid medication because of a hypothyroid condition. This is a common disease caused by a gluten intolerance. I offered for her to look at my book on Celiac Disease. I let her borrow it for a few hours. Roughly 1 week later her 16 year old daughter was hospitalized for 3 days with abdominal pain. She was placed on IVs and morphine. It turns out she has Celiac Disease and her intestines are flattened. I did not know this before, but her daughter was on antidepressants and several other medications prior to finding out she was a Celiac!
Stick with the diet for at least a few weeks and let me know how you feel. I have not, but maybe keep a diary of your thoughts and some observations about how you feel throughout the day. Stick to the vegetables you like. I can guarantee that you will eventually start looking around at vegetables other than the ones you know you like.
