Bryan; the amount of time between meal and snack will depend on how long you have been eating in the Zone.
Generally, Individuals will vary slightly on the timing of their snack... which is perfect... That is how it should be.
I think your doing well.
I really like Dr. Sears way of eating and his approach. He understands we are not cut out with a cookie cutter.
We are individuals and being such, our dietatary needs vary slightly. So listening to your body's response to the food your putting in your mouth is very important.
I think a good example of what I am saying can be found at : http://www.drsears.com/portals/6/Do...lchart.pdf
