Now people not only pay more attention to healthy diet, but also have more good fitness methods. Many people have noticed that they usually eat very little and exercise a lot, but they are not thin. Why?

The main reason is the slow metabolism, especially after the age of 30, the metabolic function will gradually decline, which is why it is more difficult to lose weight in middle age. Here are four ways to improve metabolism for your reference.

First, the training mode changes from aerobic to strength. Many people say that aerobic exercise should last more than 20 minutes to achieve the effect of burning fat. In fact, we can exercise effectively in 20 minutes by HIIT method. And pay attention to strength training.

Because HIIT can burn fat efficiently, it is the best fitness choice for people who have no time and weak willpower.

Strength training has a more stimulating effect, switching between tension and relaxation, and greatly improving metabolism after completion.

Second, pay attention to the correct drinking time. Drinking water can accelerate fat burning and metabolism. In the past, eight glasses of water a day were advocated in the market. It doesn't really matter. What matters is when to drink. Some surveys have found that drinking two cups of boiled water before meals can reduce 4 kg in three months.

Third, add high-quality protein. After strength training, muscles will be tired. At this time, protein's muscle fiber tissue can be supplemented to increase muscles. Muscle increases, fat burning efficiency increases, and metabolism in the body accelerates.

Fourth, pay attention to drink more green tea. As mentioned earlier, drinking time is very important. It must be mentioned here that EGCG in green tea has a very obvious effect on burning fat and improving metabolism. It is found that 4 cups of green tea a day can increase metabolism by 10%.
