Drinking a cup of coffee before exercise is more helpful to burn fat.

A cup of coffee has both aroma, sour taste, bitterness and sweetness, and the rich taste has become a small helper for people to pick themselves up in the morning. Not only that, drinking coffee also helps to improve concentration, and coffee is the best choice when you want to relax, so omnipotent coffee has been shown to help you lose weight in a recent study. The relationship between coffee and fat burning was studied by Professor Masahiro Suzuki of Tokyo Tzu Hui Medical University, who focused on caffeine, the main ingredient of coffee. A cup of coffee contains about 60-100mg caffeine, a bitter substance that activates the brain and suppresses fatigue, which is why coffee is popular as a refreshing drink.

In his study, Professor Suzuki divided the subjects into three groups: "exercise after drinking boiled water", "exercise after drinking coffee" and "standing after drinking coffee". Run for 30 minutes after drinking a cup of boiled water or a cup of coffee (equivalent to moderate intensity running on a treadmill).

Professor Suzuki explained the results of the study: "an hour after drinking coffee, the sympathetic nerve was excited, and the free fatty acids in the blood changed into energy-supplying forms with increased concentrations. In addition, the fat burning index (respiratory quotient) can last for 5 hours. " Even if you just stand still after drinking coffee, you can also find an increase in energy metabolism. "if you start to exercise after drinking coffee, the effect of energy metabolism will be better and more lasting."

So, can you burn fat just by drinking coffee? Professor Suzuki said that it is rare for fat to be converted into free fatty acids to provide energy under the action of caffeine, and it would be wasteful to make poor use of these free fatty acids at this time. And it needs to be emphasized that even if fats become free fatty acids under the action of caffeine, if these free fatty acids are not consumed by muscle through exercise, they will soon return to neutral fat. In other words, drinking coffee without exercise alone cannot achieve the effect of burning fat to lose weight.

So, how to drink coffee, when to drink coffee, this kind of fat burning effect will be the best? How can exercise be more appropriate?

Professor Suzuki said: "30 minutes after drinking coffee, caffeine begins to enter the bloodstream, while stimulating the sympathetic nerve is active and this state will last for five hours, when the body is in a state of flammable body fat." In daily life, as long as you choose the right time for about half an hour of aerobic exercise. Even if it is not strenuous exercise, walking can help burn fat as long as you are in the right posture. But the first thing you need to do is to choose a sport that you can stick to. "
