Competitive chess can be extremely grueling, not only mentally, but physically as well. The amount of energy required to maintain concentration for hours on end, to handle the emotional ups and downs and the concomitant adrenaline surges and exhaustion, is amazing. There are tales of World Championship combatants losing tens of pounds during their one to two month battles over the board.
To a lesser extent, I have noticed I can consume more in a weekend of chess, with little or no exercise, than in my typical days programming computers and working out, with no resulting weight change. So, although a practitioner of CRON (Calorie Restriction with Optimal Nutrition), I often allow myself a few hundred additional calories a day while playing in a tournament. Of course, we’re still talking high-quality nutrition here. The extras come in the form of snacks for each game to keep the brain fueled and a celebratory (or consolatory, as the case may be) beer for the evening.
I pack all my food for such events in order to avoid the junk in restaurants and to allow for the odd and sometimes rushed meal windows in between games. Here is what it looked like this weekend as I prepared for the NH Open Chess Championship.

This provides for a breakfast of homemade soy yogurt (the little container) with dry cereal (not shown), blueberries and strawberries, and lunches and dinners of chili. The bags, one for each day, contain raw broccoli, cauliflower, kale, collards, and romaine lettuce for dunking in the chili (eaten cold at lunch and heated up at my friend’s in the evening). The beers (here Harpoon Oatmeal Stout) are one for me and one for my friend, who so kindly let’s me crash at his place, to end each day. Then there’s a banana (or apple) and homemade seitan jerky for each game (2 per day). I usually include a little dark chocolate as well, but left it out this time for no particular reason.
