1. High-intensity exercise: Aerobic exercise, such as jogging, swimming or skipping rope, helps to improve heart rate and metabolic rate.
2. Increase muscle mass: Strength training, such as weight lifting or fitness, can improve muscle mass, because muscle tissue consumes more energy than adipose tissue.
3. Balanced diet: Ensure adequate nutrition, including protein, vegetables, fruits and whole grains. Avoid eating too much sugar and processed food.
4. Avoid low-calorie diet: Long-term low-calorie diet will lead the body to enter a dieting mode and slow down metabolism. Make sure you get enough calories to support your body's normal metabolism.
5. High-quality sleep: Adequate sleep helps to maintain the normal metabolic rhythm of the body. Adults are advised to sleep for 7 to 9 hours every night.
6. Drink water: keeping your body fully hydrated will help promote the normal operation of metabolism. It is recommended to drink enough water every day.
Please note that an individual's metabolic rate is influenced by genes, age and other factors, so not everyone can significantly improve the metabolic rate through these methods.
