What should I be eating?

摘要

If one of the reasons you signed up for exercise was the thought of guilt-free bowls of pasta (carb loading boosts performance, right?) you better make sure you are working for it. Unless you are planning to go hard for 90 minutes or more, you can step away from the carbonara, says Louise Burke, head of nutrition at the Australian Institute of Sport. However, for long workouts, like a big race, it can help. When elite male cyclists doubled their normal carb intake for three days, they increased their power output by 6 per cent and their speed by 1.3 kilometres per hour in a 1-hour time trial that followed a strenuous 2-hour ride.
