A new study has found that intake of strong Coffee 30 minutes before a workout can improve the rate of fat your body burns as you exercise. The researchers at the University of Granada in Spain have found that 3mg/kg of caffeine – roughly the equivalent of an eyeball-shaking espresso – increases the oxidation or ‘burning’ of fat during exercise.
The small group of men whose mean age was 32. participants completed an exercise test once a week for four weeks. After standardizing other factors like time elapsed since their last meal or physical exercise, they ingested 3 mg/kg of caffeine or a placebo at 8 am and 5 pm before starting the. Later fat oxidation was measured.
After the test, the researchers have found that acute caffeine ingestion 30 minutes before performing an aerobic exercise test increased maximum fat oxidation during exercise regardless of the time of day. The effect was stronger in the afternoon than in the morning. The caffeine content in the strong coffee raises the core body temperature and which in turn increases the number of calories you burn.
