Why do you lose your body shape as you get older, even if you maintain the same diet? Don't worry yet, it's not because you're sick, it's because your metabolism has dropped and your body can't carry the same amount of calories as before. Here are 5 tips to improve your metabolism, keep your body healthy and burn fat to get back in shape!

1. Drink more water

The human body is 60% water and most of the physiological functions require water to carry out, which shows that water is indispensable to our body's metabolism. However, drinking water may also temporarily speed up your metabolism. The amount of water each person should drink per day is: body weight (kg) x 30cc, e.g. for a 50kg person, the amount of water drunk per day is 1500cc. However, if you sweat easily or are a manual worker, remember to increase your water intake by about 500cc!

2. Drink green tea

Green tea not only fights cancer, but also speeds up metabolism. Studies have shown that people who drink green tea 3 times a day or consume green tea extract 3 times a day have a 4% faster metabolic rate than those who do not. Theoretically, you can burn an extra 60 calories a day and lose 6 pounds of fat a year just by drinking green tea. This is because green tea contains catechins, which increase the level of metabolism-boosting noradrenaline in the body.

3. Regular aerobic exercise

Aerobic exercise is the most powerful way to increase your body's metabolism, it can make every cell in your body extremely active. For those who are always facing the screens and working in a sedentary style, they should do some aerobic exercises. Keeping up with some aerobic exercise every day can also be of great benefit to your health!

4. Get a good night’s sleep

Adequate sleep is a must for maintaining a good figure. Increased thyroid levels due to lack of sleep and hormonal disruptions due to stress can slow down metabolism. When you feel tired, your body's energy for normal bodily functions has turned on the red light, meaning that there are not enough calories for fat burn. So, if you want your metabolism to function properly, get 6 to 8 hours of sleep a night.

5. Relax yourself

Many studies have shown that stress is strongly associated with the accumulation of abdominal fat. When you feel stressed, a number of hormones such as cortisol start to stimulate the appetite and lower the body's metabolism. This encourages fat to build up in your belly, so you look like a balloon being blown up. What can you do at this moment? Relax, listen to soothing music, or practice yoga. Do something you enjoy every day that relieves your stress.
