I have heard that the first 20 minutes of walking/running you burn carbs. After that you burn fat. Is this true. Can I just walk/run for 15 to 20 minutes a day and still burn fat.

you are burning calories, those calories come from whatever you ate, the more you burn the less will turn into fat. If you get a good 15/20 minute workout in you will burn some, if you do it longer you will burn more.
