According to a new study published in the International Journal of Sports Nutrition and Exercise Metabolism, drinking coffee or another caffeine source an hour before exercise can help you burn 15 percent more calories during exercises.
Caffeine is a natural stimulant that accelerates the workings of the respiratory system, metabolism and increases adrenaline levels in the body.
Some of the best sources of caffeine, with the exception of coffee, are green tea and cocoa.
Although previous studies have found that pre-exercise coffee can increase the effectiveness of exercise, this is the first study that has come up to the conclusion that coffee can cause even faster calorie burns, even 3 hours before working out.
Scientists from Spain have completed the study, which was attended by 12 men who had exercised every day for 30 minutes to 1 hour. Scientists divided them into groups. One group had received placebo, while the other had caffeine.
The researchers then measured the speed of heart beats, blood pressure, and breathing rate during and after exercises.
The results of the measurements showed that the best dose of caffeine, which you can consume before exercises, is 4.5 milligrams per kilogram of body weight, which is approximately one cup of medium-sized coffee.
Also, scientists have found that coffee had boosted calories burning for even 15 percent. Participants who had taken caffeine prior to the exercise had burned more calories and rested for 3 hours after exercise.
Therefore, if you have noticed that the exercise is not giving the desired results so quickly, scientists suggest that you try to drink coffee, green tea or cocoa about an hour before the exercises.
