Weight Loss: A Good Cup of Coffee Before Exercise Could Speed ​​Up Fat Loss: Study

Can’t go a day without your cup of coffee? Well, you are not alone. It’s almost amazing how just one cup of coffee can make a bad day a little more bearable. It turns out that it could be of immense help on your weight loss journey as well. According to the results of the latest study, drinking a good cup of coffee before exercising could stimulate fat loss. The study, published in the Journal of the International Society for Sports Nutrition, found that caffeine (about 3 mg / kg, the equivalent of strong coffee) taken half an hour before aerobic exercise significantly increased blood pressure. fat burning rate.

The study also noted that the effect of caffeine is stronger in the afternoon than in the morning. In other words, exercising in the afternoon after a good cup of coffee can be more effective.

Through their study, the researchers set out to determine whether caffeine, an ergogenic substance widely consumed to improve athletic performance, actually increases the oxidation or “burning” of fat during exercise.
The popular recommendation of drinking coffee on an empty stomach for faster weight loss may lack a scientific basis, as it is not known whether this increase is due to exercise in the morning or going without food for a longer period. long, the official said. author of this research, Francisco Jose Amaro-Gahete of the Department of Physiology of the UGR.

For the observational study, 15 men (mean age, 32 years) were examined. They were asked to take a stress test four times at seven-day intervals. Subjects ingested 3 mg / kg caffeine or placebo at 8 a.m. and 5 p.m. (each subject performed the tests under all four conditions in random order).

The prerequisites for each stress test (hours elapsed since last meal, exercise, or intake of stimulants) were strictly standardized and fat oxidation during exercise was calculated accordingly.

“The results of our study showed that acute caffeine ingestion 30 minutes before performing an aerobic exercise test increased maximum fat oxidation during exercise regardless of the time of day,” explains Francisco J. Amaro.
The results confirmed the existence of a diurnal variation in fat oxidation during exercise. Values ​​were higher in the afternoon than in the morning for equal hours of fasting.

Caffeine has been claimed to increase fat oxidation during morning exercise in a manner similar to that seen without consuming caffeine in the afternoon.

Scientists conclude that a combination of acute caffeine consumption and aerobic exercise performed at moderate intensity in the afternoon is effective for people looking to increase fat burning during exercise.
