weight loss goal

I have found that it helps me to eat less before going to bed when I go to gym after work.  I am too tired to worry about food.  I have done my work out and have cut my intake. Resisting the junk food at work is the hardest part of trying to eat healthy.   
I am trying to lose 5 pounds  by August 5th.  I think that gives me time but makes some requirements of myself.  That is not my final goal but I know that it will be achieved a little at a time.
