The Zone should help you keep up with your busy schedule!

Please remember the Zone is about hormonal control (ex. insulin). That is why it is important to have your B4 bed snack, to stabilize you thru the night and to eat (at least a block) within one hour of waking.

I know it's hard to get into the idea of not exercising on an empty stomach, but once your "Zoning", your body will burn FAT 24/7. It might be something as simple as a cup of 2% milk to start your day. It's not exactly 100% Zone, but close enough (most folks don't need to be exactly precise to reap the benefits of the Zone), or what about 1/4C non-fat cottage cheese, about 9 grapes and 1 macadamian nut? Even 1/2 of a Zone bar is enough to get you going. Those are some things that may not upset your exercise routine. Then, by the time you can sit down and eat breakfast, make it 2 blocks. You may want to have another snack around 10:30.
Once you are in the "Zone", you should find you're not nodding off early. Try to get that bedtime snack in there ~ it's very important.
All of the same snacks you're accustomed to are fine with the Zone. You just need to add some low glycemic carbs and monounsaturated fat (unless your protein source is high fat). From what I know of Atkins, there's TOO MUCH saturated fat "allowed". Some great snacks are: Soy nuts, jerky, string cheese, 1/2 Zone bars, deli meat, etc. Just remember to balance everytime you eat.
