How much should a 18 year old weight if they are 5'1?

Answer 1

Usually, one can know what an healthy weight would be for them by looking at their BMI (Body mass Index). A normal BMI will be between around 19 and 24.9. Below that, it is a sign of being underweight and over that, overweight. For adults : (weight in pounds x 703)/ (height in inches X height in inches). Hence, your weight, according to this, should be somewhere between 105 and 130 pounds if you wish to be healthy. That's a pretty big margin. However, do not forget that BMI is merely one indicator of an healthy weight and that other variables are important to take into consideration such as your muscles mass and your waist size.
