Caffeine stimulates the central nervous system and increases metabolic rate. Australian scientists, led by Matthew Schubert from Griffith University, found that supplementing caffeine 90 minutes before and 30 minutes after a one-hour bike ride (65 percent of maximum effort) increased caloric expenditure and fat oxidation more than exercise (plus placebo, fake caffeine) alone. Test subjects said that the exercise was easier and more enjoyable with caffeine. Consuming caffeine (3 milligrams per kilogram of bodyweight) before and after endurance exercise promotes caloric expenditure and reduces the perception of effort.
