My diet for today 12/12/14

I realize that my diet is quite poor as my breakfast consisted of chocolate bars, brownies, and a pepsi. That was before I did some exercise.  I am not sure how many calories was in the soda but at least it burned a few.  I also consumed yogurt, an apple, and later beef sausage, bread, mustard, and eggs.  I am not sure what I need to do right now, but counting calories would be a great start.
