Drinking sugar-free green tea 30 minutes before exercise can accelerate the burning of fat. The fat burning rate of catechin supplementation before exercise was 17%.
According to the American Journal of Clinical Nutrition, 12 subjects were divided into two groups, one group took placebo before exercise and the other group took catechin. The results showed that compared with the placebo group, the fat consumption of the group taking catechin increased by 65,438 07%.
Another journal of nutrition pointed out that the researchers took 128 obese people as the research object and conducted an experiment of 12 weeks. As a result, the total abdominal fat in the experimental group who drank 500 ml of green tea every day and exercised for 3 days every week decreased by 7.4%. This study also found that when people exercise, they will secrete adrenaline, induce lipolytic enzymes, and convert fat into energy needed for exercise, thus achieving the effect of eliminating body fat. However, there are other enzymes in human body that can decompose adrenaline and hinder fat metabolism, and catechin can inhibit this obstacle, make adrenaline play its due role and improve fat burning efficiency.
Among tea leaves, green tea has the highest catechins, followed by oolong tea, and black tea is even less, only one-ninth of green tea. Nutritionist Liu Yili suggested that the effect of burning fat should be improved during exercise, and the sugar-free green tea brewed by himself is the healthiest. People can drink sugar-free green tea 30 minutes before aerobic exercise and supplement catechins to make fat burn faster.
