As for not being able to count steps.

When overweight, it means that there is too much fat accumulated in the body, that is, too many calories accumulated in the body, so doctors often tell patients how many calories they need to consume every day. According to the medical profession, such as walking slowly, the speed is 4 hours per hour. Kilometers, then consume about 2.0 calories per kilogram of body weight per hour. If you walk fast at a speed of 6.4 kilometers per hour, you will consume about 3.4 calories per kilogram of body weight per hour. If you walk briskly at a speed of 8.5 kilometers per hour, you will consume about 9.3 calories per kilogram of body weight per hour. According to this data, it is possible to follow the doctor's instructions to maintain health, but to calculate this data, ordinary sports equipment cannot do it.
