Coffee can help burn more calories

Consuming coffee (or any form of caffeine) an hour before exercising can help burn about 15 per cent more calories, post-sweat session, than you would otherwise, according to a recent research published in the International Journal of Sport Nutrition and Exercise Metabolism.

According to the study, caffeine is a natural stimulant that can increase respiratory rate, metabolism, and the amount of adrenaline in the bloodstream.

Although research has already shown that consuming the stimulant before a workout can help you work harder and longer than normal, researchers in this study found that the calorie-burning benefits of caffeine can last up to three hours after you've done exercising.

Researchers in Spain studied 12 men and women who typically worked out for about an hour, four to seven times a week. An hour before their workout, participants were given either a placebo or a caffeine dosage of 0.5, 1.5, 3.0, or 4.5 milligrams per kilogram of body weight.

After consuming the dosage, study participants exercised at an intermediate effort level for an hour and then rested for three hours. While they were resting, researchers measured their heart rate, blood pressure, and respiration.

The study revealed that the ideal metabolism-boosting amount of caffeine was 4.5 milligrams per kilogram of body weight - or about 12-ounces of brewed coffee for a 150-pound person.

The researchers also noted that, while this study only examined the effects of caffeine on metabolism after endurance training, previous research has shown that the same amount burns 15 per cent more calories up to 75 minutes after resistance training.

That's some serious after-burn that is well worth it.
