If you'd really like to lose weight, I suggest tracking your calories for a while. Everything that goes in your mouth needs to be counted. Try calorieking.com or fitday.com.

The numbers don't lie. You'll find out quickly whether you're eating enough, and can match it up to the amount of exercise you're doing.

In time you'll learn which snacks you can fit within your calorie "budget" and fill you up longer.
