I doubt te are "fat" da the descrizione you've given. That seems kind of harsh on yourself! Just exercise for a half ora o so most days of the week. Cut down on sugary, high-fat foods and stick to più natural things, like grains, fruits, and veggies. I've had a lot of dietary success being a vegetarian.

just chew gum all day,but at night eat the K cereal

Cut out certain foods like breads, soda, sugar and potatoes. Stick to an all natural diet and exercise any time te can like during the weekends.
