Learn about how your body works.
After that, count calories. There are many great websites (some are listed in the above article) that will calculate for you the amount of calories you should consume per day to MAINTAIN your body weight. To lose weight, simply subtract 500 calories from that calculated number and do not exceed it in any given day. You can use www.fitday.com to track your caloric intake.
My suggestions for what to eat: foods high in protein, high in fiber, low in sugar. No food that contains the words "high fructose" or "partially hydrogenated" in the ingredients. eat whole wheat bread instead of white bread. There are tons of things you can do and plenty of information available online if you look.
Good luck!

I recommend burning more calories by swimming or running, than you consume in your food. Look on google to find some healthy foods that are low in calories.
