Are You In The Zone?

Nutrtion is probably the only difference in the top athletes. What about the Zone diet? I spent a year weighing and measuring all of my meals. I learned a lot about portions and discipline with food during this time, but I no longer weigh and measure my food. I know what portions I need at each meal. I'll be honest with you. I still think that weighing and measuring my food would help my performance, but I don't do it anymore, because I feel it's very close. Are you eating in the zone?
