It turns out that drinking coffee before exercising 'is insanely effective for dieting'
For a diet, it is very important to oxidize fat by aerobic exercise and burn it efficiently.

When you feel tired, a substance called adenosine binds to receptors in your brain. Caffeine contained in coffee has a chemical structure similar to this adenosine, and when ingested, it competes with adenosine and binds to its receptor. When adenosine binds to receptors in the brain, people feel tired, but caffeine makes it harder for them to feel tired and tired, and it is said that their physical performance tends to improve. In fact, a 2019 study reported that caffeine improves physical performance.
The study was presented by a research team led by Francisco José Amaro-Gahete, a physiologist at the University of Granada. The research team conducted an experiment with 15 men to study the relationship between caffeine and exercise.
The research team randomly schedules subjects to 'give them a placebo at 8 am,' 'give them a placebo at 5 pm,' 'give them a caffeine pill at 8 am,' and 'give them a caffeine pill at 5 pm.' Did. After taking the drug, a cycling test was performed to measure the body's ability to burn fat and maximal oxygen uptake.
As a result, taking 3 mg of caffeine per kg of body weight 30 minutes before aerobic exercise improved fat burning rate by an average of 10.7% when exercising in the morning and 29.0% when exercising in the afternoon. I found out that I did. According to the research team, this amount of caffeine is about the same as 'the amount of caffeine contained in a cup of strong coffee.'
'Our research shows that caffeine intake 30 minutes before aerobic exercise increases maximal fatty acid formation during exercise,' said Amaro-Gahete. ..
However, because the sample size of the experiment is quite small and it is possible that morning exercise and diet may have an effect, the results of this study alone are somewhat lacking in scientific evidence, Amaro-Gahete said. Still, 'Overall, the results of this experiment suggest that'taking some caffeine in the afternoon before exercising'is a way to increase fat burning during aerobic exercise.' Said.
