3. Do you have low iron? Do you take vitamins.

I have tried to do some research on diet and have not found an easy way to tell if I am getting the right balance of calories from the food groups.

Thanks again for all of your help.

I am away on business right now. When I get back I will e-mail you with some ideas. To start you are eating way too few meals. Your tiredness may be do to your lack of energy stores. Try to eat small meals tru out the day. Between 5-6. I know this is hard,but prepare your meal ahead of time and take them to work with you. Tubberware.
Stay away from soda and sugar. Sugar will spike your insuline levels and then you will crash. Soda will also make you tired. Drink lots of water.When you go on a break try to get outside and get some sunlight. Office lighting gets me tired. Right before training,1 hour to 30mins eat something. ie penut butter and jelly sandwich. This should help you maintain energy levels. I will e-mail you more complete ideas later Ed.
