A light easily digestible diet results in much clearer neural passages so that the mind/body connection is enhanced. This is why dairy, red meat, most white meats, processed grains and sugars must be avoided. I have tried striking workouts after eating tofu and steamed vegetables, versus several big macs, fries, shake and soda pop. I could barely snap my kicks and punches, and my knees and elbows were frozen after the fast food. Omn the light diet day, I pepper the bag with swift kicks, punches and everything. I think this 100%, but off course this is just my opinion I welcome your answers.
