How To Calculate Ideal Body Weight: Easy Guide!

How To Calculate Ideal Body Weight

There can be various formulas to calculate the ideal body weight but probably the simplest is the following:

Men = 22 x height in meter = kgs or lbw 

Women = 22 x (height in meter – 10 cm)2  = kgs or lbw

Now, a person can be considered as obese if they weigh about 30% more than their ideal body weight.

Attaining the perfect number on the weighing machine depends on several factors as we mentioned. These include your muscle and fat ratio, height, gender, body at distribution and various other physiological conditions. 

There can be multiple ways that you may determine the ideal body weight. But the most available and followed methods are as mentioned below:

  • Waist to Hip Ratio or WHR
  • Body Mass Index – Weight and Height
  • Body Fat Percentage 

Though each of the above-mentioned methods can offer you a proper and good estimate, nevertheless, it’s important to bear in mind that a single result can not determine that you are unhealthy or unfit. Therefore, check with your doctor to learn about your body weight. 

Now, let’s take a look at how to calculate the ideal body weight through BMI or Body Mass Index method.

How To Calculate Ideal Body Weight Through BMI

How To Calculate Ideal Body Weight Through BMI

According to NIH or National Institute of Health, you can understand whether your Body Mass Index or BMI corresponds to the ideal weight. This calculation usually measures the weight with respect to the height so as to determine the overall mass. 

In order to calculate the ideal body weight, you need to measure the weight in kgs and then divide it with the height in meter squared format. Therefore, the formula will indicate something like the following:

BMI = kg / m^2

According to the National Institute of Health, adults of 20 years old and beyond that can be classified in the following category depending on the BMI rate.

  • BMI is lower than 18.5 = underweight
  • BMI is between 1.5 and 24.9 = normal. This is also considered as the ideal body weight
  • BMI is between 25 and 18.5 = overweight 
  • BMI is beyond 30 = obese

Too high or too low a number in the BMI scale indicates the bad physical condition.

Whereas high BMI points to overweight and obesity and can draw severe health hazards like high blood pressure, heart problems, backaches; on the flip side, low BMI may be an indication that you can have health problems like bone loss, iron deficiency, weak immunity, and anemia.

The drawback of BMI or Body Mass Index

When you are checking your body weight following the BMI method, you must know its drawbacks so as not to rashly come to any decision. Remember that this method only takes a person’s weight in relation to the height into consideration.

But it completely overlooks other important factors like the proportion of fat distribution, the amount of muscle mass, as well as the hip or waist measurements. Do you think that you should be morose after weighing the ideal body weight on the scale?

Take, for example, a fit and health concerned athlete may have a high BMI in spite of having low body fat.

This occurs due to the fact that the athletes are prone to have more of muscle mass. In such a case, high BMI along with more muscle doesn’t really mean that the same athlete we are talking about it overweight or unfit to take part in a competition.

We can show other instances as well where sex and age also offer distinct results. For instance, according to the general health survey, it’s seen that women have a higher potential to possess more body fat than that of the men.

Now having such propensity to store fat doesn’t really indicate that women’s health is at risk as compared to the men. Also, older people usually store more fat than young or adults. 

Therefore, though BMI offers a generic estimate of the ideal body weight, it must not be the only means to determine whether a person exhibits a healthy or weight or has gained some excess amount.

But, having said that we must mention that no method is a hundred percent correct and this is why you must check with a health physician or doctor to learn the ideal body weight based on your own body structure and health condition. 

Now that you have learned so much information about the ideal body weight, you must want to know yours?

As we mentioned previously, there are various online tools available in the market, but if you cannot access those or just want to verify the online result, you may try this manual method.

But please bear in mind that even the manual method or the machines can be flawed and don’t start gulping medicines based on these results. Rather consult a doctor first if you come across a discrepancy in the result.
