Article originally on required nutrition and diet for high performance athletes who are training and competing nearly as a full-time job.

For her, nutrition is a way of life. "You can't expect you'll be good to go just eating right on the day of a competition. It's not a one-day fix," she said. She follows a 90/10 rule where 90 per cent of the time, she eats to compete but enjoys some pleasure foods
Thought the 90/10 % rule was useful ..at least for lower folks like me, to eat for health and general fitness, but not to compete and have some pleasure foods. Of course the problem, could be 1-2 food items that throws one's nutritious diet for that day, out of whack.
