The basal metabolism of an adult is about 1200-1400kcal per day, and the energy consumed by the basal metabolism is much less than the energy consumed in a day. An adult’s daily energy intake is about 2000-3000kcal, energy intake is much higher than consumption, so it is easy to gain weight. If you want to lose weight, you must make the energy you consume greater than the energy you take in every day, which is the principle of weight loss, so you not only need to control your diet every day, but also need to insist on exercise. Diet should be less oil, less salt, light diet, avoid high-fat, high-calorie food intake, eat more fresh vegetables and fruits, exercise every day can be running, yoga, hiking, playing ball, cycling, etc.. If the basal metabolism is too high and far above the normal range, consider whether you have hyperthyroidism. When the basal metabolism is abnormal, you should consult a doctor promptly to clarify the cause of the disease and treat it under the guidance of a doctor.
