Energy is pressure x volume. A pressure of 762 atmospheres is about 76 million joules per cubic meter, and a volume of 56.7 liters (for a 125-pound human) is 0.057 cubic meters. That gives about 4.3 MJ, which is approximately a thousand kcal. I believe that TNT has about 1000 kcal/gram, so that's about a kilogram of TNT, or about 2.2 pounds.
