It's very possible, BobbiJo and in fact, whenever I want to get trick out my body, I do the 5-6 small meals a day and lots of cardio.
The thing that will happen is you basically deceive your metabolism. Your metabolism will speed up by eating the small meals so eventually you will feel sooo full when you try to eat a regular-sized meal and not be hungry (this means it's working) and on and on. The first two weeks are so important when you are eating this way. If you cut out soda you will lose so much weight, it's not even funny!
For me, I eat whatever I want on weekends, but M-F I do the 5-6 small meals setrictly.
