22 year old male weight 5 7?

You can calculate a healthy body weight by using the Body Mass Index (BMI).

The formula for BMI is weight (kg) divided by height (meters) squared.

A healthy BMI is between 20-25,

a BMI 25-30 is overweight,

a BMI 30 and up is obese,

a BMI 15-20 is underweight,

and a BMI under 15 is emaciated.

In your case a healthy body weight should be between 58-72kg (128-158lbs)

20 = x / 1.7^2

20 (2.89) = x

57.8kg = x

25 = x / 1.7^2

25 (2.89) = x

72.3kg = x
