Hi Luis,
Assuming you chose the highest activity level, 31 blocks is correct. An athlete at that level would eat 1 gram of protein for every pound of lean body mass (LBM). At teh weight of 246 pounds and having 11% body fat, you have approximately 219 pounds of LBM. There are 7 grams protein in one block. Your daily protiein requirement is 219 grams of protein (1 gram x 219 pounds). Your block amount is 31 blocks (291 grams protein /7).
To solve the probelm fo consumgin that much food, you can eat more often than 3 or 4 times a day. Keep meals to a manageable size of 5-6 blocks maximum, and eat 3-4 meals daily. Support your workouts with snacks to make up the rest of yoru daily block requirement. Snacks can be 1, 2 or 3 blocks each. Teh goal with the Zone is to provide your body with a constant supply of protein throughout the day. The Zone recommendation is to eat a snack prior to the workout and another snack after, unless you will be eating a meal immediately after. Assuming you workout multiple consecutive hours daily, it may also benefit you to have small snacks during your workouts. Zone shakes are excellent support for workouts. Each Zone shake contains are 3 blocks when mixed with a cup of milk. They make excellent meal replacements too. Zone bars are another good choice. Here's a link to Zone shakes and bars:
