Drink a lot of water, dont eat a lot, snack on junk food evenly or less then snacking on fruits/veg in the fridge (many times i have them precut).
I do that and i LOSE weight and i walk < 1hour a day. This is impossible? Well almost. I break even much of them time the days i go out and walk the streets i come home 1/2 pound lighter. I always feel energies and the water helps (I drink 3L a day bro ;P. No joke)
