During short-term exercise, the body burns carbohydrates as its first fuel, but during long-term exercise, the body depletes carbohydrates and starts to burn body fat. Doctors said that astaxanthin, the bright red carotenoid in salmon and shrimp, increases muscle enzymes that help convert fat to energy. To test this theory, 14 competitive cyclists took 4 mg of astaxanthin per day, or a placebo. After 28 days, the bikers fasted and rode for two hours to deplete stored carbohydrates, and then took a 12-mile time trial. The astaxanthin group completed the trial much faster than placebo.
