1, male: (height cm-80) × 70% = standard weight.
( 178-80)x 0.7 = 68.6
2. Standard weight = height (m) × height (m) ×22
1.78 x 1.78 x 22 = 69.70
3. Body mass index = weight (kg) divided by the square kg/m2 of height (m).
Formula writing: body mass index = weight/(height) 2
Normal weight: body mass index = 18-25.
Overweight: body mass index = 25-30.
Mild obesity: body mass index >; 30
According to the standard body mass index 18-25.
18 =? / 1.78/ 1.78 ? = 57kg (1.78 guy 57kg is normal? )
25 =? / 1.78/ 1.78 ? The standard weight of the above algorithm = 79kg is lower than 70kg, and the normal weight of this algorithm is lower than 79kg. Isn't the gap too big? About 65 kilograms. That's not the most important thing. As long as you are healthy enough, this is not a problem. Some people are at the lower limit of the standard range, while others are at the upper limit. There is a big difference between the two, but as long as there is no disease, they are all healthy. If you feel that your body shape is not perfect, you can go to the gym.
