First you really need to get a breakfast in. Try boiling some eggs ahead of time, so you can just grab them. Maybe some Atkin's canned shakes, those you can grab and drink on the way to work. But I really think you need something.

Also you seem to be a bit light on food, if you don't eat enough your body may hold back thinking you are starving yourself. Eat as much meat as you want till you are satisfied.

May I suggest using Fitday.com and tracking your intake for a few day.

I am really worried that if you don't get enough food to run your body. The basic rule of thumb if you wanted to track your calories is, 10 to 12 times your current weight. And getting more fats in will help you lose better. How many times do you get to here that one in your lifetime?!?

Also I think you need to try and get in some more veggies.
