Before using a height weight scale, you need to know how to read the height and weight scale.
Body mass index (BMI) is a person’s weight in kilograms divided by the square of height in meters. BMI result can reflect the people’s body condition—underweight, normal weight, overweight, and obesity.
For example, if a people weigh 65kg and height is 180cm, his BMI= 65/1.8²≈20，which indicates his weight is in normal range, we normally need to care about our body weight rather than care about our height, because we can control our body weight but cannot control our body height when we are an adult, as we all know underweight or overweight is quite annoying for our daily life, and we should be aware that our body weight is an index of our healthy body, after all, a healthy body is priority element in our life, much important than career, money, honor etc.
So once you read your height and weight result, calculate them by BMI formula, if you are overweight or underweight, please consult your physician and ask for health advice, you might need to change your food habit, do more exercise or take some medicines.
One more thing, keep measuring your body weight every week and make this your life habit, keep an eye on your body weight and body shape, your life will be happier and better.
