Eating before karate training - overweight 40 year old karateka?

Well, I would definitely recommend eating very lightly around 5:30 or 6 that way it doesnt "weigh you down" during your karate session. Eat light, like a salad and tunafish. Try to stay away from bread because it tends to make you more sluggish during exercise. Drinks? WATER only in my very professonal opinion. and if you feel like you need energy then eat an orange, its fantastic for electrolytes and that extra boost of energy. if you need any more help you can consult this website. its always worked for me. purelyprogress.com I hope i helped you. :)
