They advertise to have 2 meals of cereal per day for 2 weeks.
Not sure if they intend for you to continue after 2 weeks, though.
I think it says lose an inch off your waist in 2 weeks.
I'm sure it can work, because a bowl of cereal is what? 200 calories?
Sometimes I have Kashi cereal for lunch if I don't feel like making a sandwich
