Keep a food journal or diary.  Writing down what you eat and the calories can really encourage you to eat less.  Look at it often and frequently.  You don’t realize how many calories you consume in a day until you are forced to look at it – it will make you sick. 

Also, you can add a calorie counter gadget to your homepage which is very handy!
