When it comes to winter, do you prefer to have a hot drink? But today's drinks are heavy in sugar, which is not a good thing for dieters. But coffee and green tea are the best fat and weight loss supplements, which definitely make you addicted to your mouth without having to worry about getting fat.

A cup of plain coffee before exercise

Coffee can significantly increase energy and fat consumption during and after exercise. Of course, the coffee here refers to pure coffee without sugar or milk.

In a study published by Griffith University and the University of Queensland in Australia, they tested energy and fat consumption in coffee + exercise, exercise alone and no coffee and no exercise. The sport in the experiment is an hour of cycling. The results showed that drinking coffee plus exercise had a significant effect on energy and fat consumption.

Another study compared caffeine intake with placebo EPOC before and after exercise. (EPOC is during exercise, and the sugar you owe is returned to the body in the form of fat after exercise.) The results showed that within 3 hours after exercise, the EPOC of the caffeine group was significantly higher than that of the placebo group.

The prevailing view in the scientific community is that this may be because coffee stimulates the central nervous system, speeds up metabolism, allows fat to participate in consumption earlier and more, and increases fat utilization by muscles.

It is recommended to drink a cup of plain coffee without milk and sugar an hour before exercise. If you can't accept it, you can add skim milk, but don't add sugar. Coffee with high sugar content should be consumed with caution.

Catechins improve the ability of fat burning

But there are always people who can't drink or are not used to drinking coffee. Don't worry, green tea is also a good choice. There are more than 30 kinds of polyphenols in green tea, such as catechins, flavonoids, phenolic acids and so on. High concentrations of catechins can accelerate sympathetic nerve stimulation and change energy utilization after exercise.

Scientists found that subjects who took a daily supplement of decaffeinated green tea extract (571mg) increased the oxidation rate of fat by 24.9% and decreased body fat by 1.63% after four weeks. In other words, green tea can also promote the body's use of fat, making you more fat-burning ability.

In other studies, when rats were given green tea extract before and after exercise, scientists also found that green tea can increase the antioxidant function of red blood cells, which is more conducive to the improvement of aerobic endurance and health during exercise.

It is generally recommended that you drink it an hour before exercise. However, drinking green tea is not recommended after training. It is generally necessary to eat immediately after training to promote recovery and growth, and to replenish protein, and the tannic acid in green tea will combine with the protein in the food to form a massive tannic acid protein that is difficult to digest and absorb, hindering your absorption.
