When I'm in training, I eat no solid food except hot dogs for six weeks.
I'll have an omelette, porridge, and fruit for breakfast at the training ground, then chicken, pasta and soup for lunch; then I can relax in the evening.
I try to live by the 80/20 rule - 80% clean, 20% cheat. During the week and while I train, I eat as clean as possible. But I always like myself a good cheat day, which includes a juicy burger.
When you're training for jiu-jitsu, particularly if you're training for a competition, you have to be pretty prescribed in the variety of what you eat.
I would be lying if I said I cut out all dessert. When I'm training, I try to satisfy those cravings with a slightly healthier dessert, like a piece of dark chocolate or whipped cream and strawberries. Those are two of my favorites!
Sometimes I'll have cheesecake - just anything that's high calorie, because that's what I need for the training.
When I'm training hard, the diet is miserable.
Fruit is carb-based, and I limit carbs when training hard.
My diet is usually pretty consistent whether I'm training for a specific fight or not. I don't like to mess too much with it.
I train for about 25 to 30 hours a week so I need to eat a lot. You just need to have a generally healthy diet. You need to be eating foods with lots of vitamins and minerals. You need to make sure you eat properly in order to give yourself the best chance of performing and recovering from training and competing.
