Eat Like A Champion – Nutrition In Chess

If you don’t eat crap or shit you get better?!
Research topic: Does eating refined sugars lead to crazy gambits in Chess?
mmmmm all to give publicize to Hammer Nutrition Bars?
It's very interesting how nutrition affects not only our physical capabilities, but also our mental ones. Although now I know drinking too much coffee is not the best thing to stay focused on playing, I can't say I won't do it again. :p
Even though i have never played OTB, the advice sounds accurate. That's what i would do, if i ever play in a future tournament.
I have noticed that playing when hungry, degrades your performance, partly becauuse of the low glucose levels, and partly because hunger distracts your mind when calculating. It even makes you tend to play hastily, probably in a subconscious atempt to get done with the game and go to eat.

BUT: whatever we can say about proper nutrition stumbles in the fact that, if you look at their pictures, they reveal that some of the best chess players in the world obviously do not give a f*&% about their nutrition. It is as clear as an obelisk in the middle of the desert, that Nakamura, Nepomniachtchi, Kramnik and quite a lot of other pleyers, never followed any nutritional instructions. It is very hard to argue that this indifference to nutrition harmed their careers, or the quality of their game, especially Kramnik's.
I never thought of this, thanks for the info I will definitely incorporate it into my chess tournaments and games.
Glad to see this topic being brought up. So many "unrelated" things actually affect performance, whether in chess or other fields. Food is critical. Beside nutrition, sleep, stress levels and many others can either improve or hammer performance. Some people might claim that top players break these rules and still get results. Yes but how often we see them under-performing and under all of it might be these mistakes.
