Wow, I just read you go to bed bet 3-5 am?
I'm just about getting up at 4:30am..
Anyway, it really doesn't matter what your schedule is; you still should have the same amount of meals/macros. Hopefully you get plenty of rest.
Because your diet is so erratic is best you try to adjust to a new eating or it won't last you long.
If you can't have gluten, I suggest to avoid it or you'll get more pain and more bloat. I too had to give it ufter years od being in denial.
You don't get up for breakfast, but you still can have it.
Meal #1 1/2 Oatmeal (will give you energy) and 3 egg whites, 1 yolk.
#2 Salad (since you love salads) with breast of chichen or turkey or fish. Use balsamic vinager or light dressing.
#3 Chicken/turkey/fish with 1/2 cup of brown rice and vegetables.
#4 protein drink
#5 Fish with vegetables.
Avoid any process food or refined sugars.
Drink lots of water.
Always remember, if it comes from the ground is ok to eat.
With this you will burn fat and will not lose a lrge amount of weight, which is what you need.
If you have any questions, please ask..
Oh, if you fail a day or two, is no big deal, just go back and start again. That said, try to do your best to stick with it in order to see progress sooner.
Keep us posted!
