Sounds like you have your body in a great place. It's in the "Zone" as they say :-)
I grabbed some older post i thought were good: One is from Sue (Consultant of Zone Labs ) who is really knownledgable about all things Zone. the other is from Tech support.
The caloric recommendations/requirements you've found on other sites most likely refer to a person who is burning carbohydrate to produce energy. In the Zone you are burning fat to produce energy. One calorie of fat produces more energy than one calorie of carbohydrate. If you follow the Zone diet you will be producing more energy on fewer calories as compared to person who is producing energy from carbohydrate. You also need to take into account that when you follow the Zone Diet 24/7 your body will also be tapping into it's stored body fat to produce energy. Most individuals have enough stored body fat to provide the caloreis needed for multiple marathons. If you've chosen an appropriate activity level for your Zone protein requirement calculation you do not need to consume additional blocks. Have fun training for the 1/2 marathon!
Lost 100 lbs 17 yrs ago, off BP meds, thanks to the Zone diet and Zone fish oil. ZoneFast 1-2-3 is the best!

Each athlete and individual will require minor adjustments when tuning in their block requirements for the day. Did you use the Body Fat Calculator located on this site (http://www.zonediet.com/tools/body-...alculator)
and did you input your activity level ?
Your activity level for the purpose of calculationg daily protein /block requirements is active, leaning toward very active. I would need to know your measurements to calculate for you.
Eat at least 4 times per day and space meals and snacks at regular intervals wherever possible. Try 4 meals or 3 meals and 2 snacks or 3 meals and 3 snacks or whatever works for you. Just distribute the recommended block requirements among the meals and snacks so that they total your daily requirement. A plan for an 11 block day may look like this: 3 meals of 3 blocks and 2 snacks of 1 block or perhaps a 3.5 block breakfast, a 2 block lunch, a 3.5 block dinner and a 2 block bedtime snack.
Try not to go over or under your recommended daily requirements. However, if your daily requirement seems like more than you can eat then don't push yourself.
Always match your protein, carbohydrate and fat blocks in a 1:1:1 ratio every time you eat. If you plan to eat 2.5 blocks of protein then be sure to have 2.5 blocks of carbohydrates and 2.5 blocks of fat during that same meal. Regarding the fat, however, you can go higher if you need (or want) to. Just don't cut it short. Most important though is that the protein and carbohydrate blocks balance.
Remember, a block of protein is 7 grams, a block of carbohydrates is 9 grams and a block of fat is 3 grams. Balancing is done block to block to block, not gram to gram to gram.
Consume unsaturated fats wherever possible. Avoid saturated fats and hydrogenated oils such as margarine and "fake" cheese. Nuts, olive oil, and avocados are among the best sources of fat and contrary to popular belief, they will do little to your weight.
Foods with a high glycemic index such as grains and potatoes should be eaten sparingly.
Avoid foods that are high in arachidonic acid such as organ meats, red meat and egg yolks. Try more fish, fowl and egg whites instead. Grass feed red meat are the best of any red meats!
