I didnt really alter my diet for soccer this summer except I stopped drinking before the game...
I know, its a bad habit, I used to do it all the time for rec because I didnt have to try very hard to excel in rec because the competition isnt very high.
Unfortunately we started to go out for beers before men's league games and thats where I found I started having trouble. Especially as rec had made me lazy so I found my performance at higher levels of competition had started steadily declining.
So, thats my advice. Dont pre-game it. And I find that a lean breakfast of cereal and a sandwhich or soup for lunch and then a meal replacement bar about 2 hours before the game works well.
Hell, it sounds like we could start a CP soccer team, what leagues/divisions are you guys playing in?
Unfortunately, we would be the out of shape team apparently.
