Can I lose weight if I eat cereal for Breakfast and Lunch?

So is it possible to lose weight by eating cereal for Breakfast and Lunch and eat a regular meal for dinner?

Also how many pounds can I lose in 2 week, if I do this everyday?
And will I lose fat everywhere? (Arms, legs, stomach, ect.)

Also do some toning workouts for 30 minutes everyday.

And thank you!
