Do you have an eating plan that is geared around your training schedule?
Losing weight while learning Martial arts presents an interesting challenge - energy requirements!
I personally find that training on an empty stomach is a quick trip to "out of gas", that my stamina is very poor, and my performance suffers, especially while sparring.
I like to eat about 1-2 hours before training (timing depends on how heavy a meal, what time of day and what kind of training I am doing.).
I like carbs before training, as it seems I have the most available energy if I'm generous with carbs first... but if I'm gearing up for a long day of training, or going to a tournament, I want some lean protein in the meal as well, so I don't fade as the day moves on.
What works for you?
