Hi Carrieann, and thanks for the question. It is dynamic on so many levels. First, you should definately see a doctor to find out if you suffer from Celiac OR anything else. It could be hormonal, ya never know. You can go to:
http://www.celiaccentral.org/Celiac-Disease/21/?gclid=CIfY983236YCFRiAgwodThlG2g and read all about it. The best thing is to learn as much as you can. Also, I don't recommend anyone for that matter, to go on line to try and diagnose yourself. This board is a forum for sharing information. You should always seek professional help where ever you can, with someone you can actually trust.
So, lets look at this another way. Think of yourself as a furnace. You have to light the fire (your metabolism) and keep throwing logs on to keep it burning bright and hot. If you DON'T EAT but once a day, you are already in such a caloric deficit I can't even imagine how you can work holidays in a florist! It's like you are starving yourself.
In my late 30's....I remember for a long time, I could NOT NOT NOT eat breakfast. The thought would turn my stomach. It was only until I realized that my insulin levels were running crazy and I would go for that "power bar" to get my sugar rush, which only lasted an hour. I also drank LOTS of coffee on and empty stomach. Then the "heart attack scare" happened, and it was only when I simply started eating a hot cereal in the morning that my body began to respond.
I found my appetite growing stronger. Even now, I have 4 eggs for breakfast, 2 whole, 2 just egg whites. One serving of Coachs oats and I am good to go till around noon. Lunch is a simple sandwich of sprouted grains bread, some sort of meat, like ham, turkey or beef, topped off with a couple slices of tomato and a slice of cheese. If you break all that down, you are getting all you need for a meal, and it keeps me going till mid afternoon, when i have a protein shake (265 k/cal) and give that time to digest, then after closing my studio, head to the gym for my hour workout! Home again, and maybe have a small piece of chicken, fresh veggies, complex carbs, like rice or sweet potato. Thats it! It is not rocket science. Oh, on Sunday? It's a day of life celebration. I always indulge myself in cookes, cake or any other thing that I normally omit during the week, so I use it as a reward for at least just trying to stay on track. No guilt, I got enough of that from my Catholic upbringing.
Often times people make it so darn difficult to LISTEN to their body and give it what it NEEDS. If its screaming for CHEESE, then listen. Give it cheese. Not to get too technical, and I already have mentioned metabolic SHUTDOWN. That's really a huge part of your problem...you are simply NOT getting the LOGS you need to sustain a fire. If you loose too much muscle mass, sometimes you can be a trip away from the hospital with a simple strain of the flu. Your body is simply not strong enough to get sick, and then stop eating. Eventually you will run out of LOGS to burn...then what? Give this some strong consideration. You can get around this, I know you can! But bottom line? It's all up to YOU...we only get so many days in a life, and our responsibility is to be good to others and be good to ourselves. I wish you all the luck, now get moving and let us know what the doc says! PEACE....DAVE
