This is actually pretty important, all things considered.
A teammate I was drilling with had to keep stopping due to heartburn and kept muttering, “I shouldn’t have eaten those french fries…”
Oh and by the way, this was a technique that required you to be in the “knee in the belly” position. When he first complained, I bounced a little in that position, because he’s a friend, a white belt and driving home the point that you really should not eat fried food before training.
It’s hard to eat healthy, I get it, and when we think of eating food that’s bad for us, we tend to think in long term consequences, like “oh, I’ll get fat, it’ll clog my arteries eventually,” so on and so forth. Eating poorly right before class has a more short-term, immediate effect when you begin to attempt to drill and train. That brick you feel weighing you down in your stomach is actually the Big Mac and fries combo you ate during lunch, and now you are experiencing the immediate consequences.
So please, this is what I have to say on the matter. Don’t eat fried food. Not because of the long term, astounding health benefits that come from abstaining from fast food, but because no one wants to feel like they are going to puke when training.
