Ok.. Sorry If I am bringing up already covered material. I did a search and couldn't really find what I was looking for so here it goes.....

The idea behind eating more meals in a day is what??
The two I hear constantly are..

1. It keeps your metabolism up. Or raises your metabolism. Making it 'easier' to lose weight, etc.
2. It makes for a better more even distribution of needed protien and other things throughout the day. Therefore being better for you.

Now my questions are...

a) Which of these is right? Or are the both right?
b) Are there scientific studies that show it does infact raise metabolism?
