What is BMI?

Your Body Mass Index is often referred to as your BMI. It is the equation that your health professional uses to determine whether or not you are in a healthy weight range. This is basically a calculation that evaluates the relationship between your height and your weight. As your height doesn’t change once you become an adult, the only way to change your BMI is to change your weight. Your Jenny Craig Consultant can help you work out your BMI using a BMI calculator. Jenny Craig uses a Metric BMI calculator to measure your weight in kilograms. The accepted categories for BMI are: 18.4 or less (underweight); 18.5 – 24.9 (healthy weight); 25.0 – 29.9 (overweight); 30.0 or more (obese).

 

How do you calculate BMI?

The BMI is calculated using a simple equation (your weight, divided by your height squared. The simple equation is: Weight ÷ Height squared = BMI. For example, if your weight is 70kg and your height is 1.7 metres, the equation looks like this: 70 ÷ (1.7 x 1.7) = 24.2 BMI. All you have to do is measure your height and weight and insert your personal specifications into the equation, or a BMI calculator, to determine your BMI.

 

How do you work out BMI with a calculator?

With a calculator, it's easy to work out your BMI. All you need to do is put in your weight in kilograms and your height in metres and complete the calculation. Within moments you will know whether you are in a healthy or unhealthy weight range. Your Jenny Craig Consultant can help you devise a weight loss meal plan and activity plan that addresses your weight loss needs. The equation is: Weight ÷ Height squared = BMI. Example: If your weight is 90kg and you are 1.6m tall, your calculations should be as follows: BMI = 90 ÷ (1.6 X 1.6) BMI = 90 ÷ 2.56 BMI = 35

 

How do you calculate BMI in kg?

In Australia and New Zealand, your medical professionals will always use the Metric system and calculate your weight and your BMI in kilograms. If you are accustomed to using an Imperial system, you will need to convert your pounds to kilograms to get the correct BMI for your body (1kg = 2.2 pounds approximately). So if you weigh 200lbs your weight in kilograms is approximately 91kg (200 ÷ 2.2 = 90.9kg). There are lots of online conversion calculators to help you with this. If you need a hand, your Jenny Craig Consultant is always available to help you work things out.

 

How to calculate BMI for a female?

There is not a separate BMI calculator for women. Males and females can both use the exact same BMI Calculator to determine their BMI. The weight range for healthy and unhealthy is the same for both. Women and men are naturally different in body composition, so there are variations and exceptions to this rule.

At Jenny Craig the Consultants can help you determine exactly what you need to do to improve your BMI. As you lose weight, you can continue to input your details into the BMI calculator and keep track of your progress.

It’s important to note that pregnant women are not included in the BMI calculator for women and should only undertake weight loss programs under the direct supervision of a doctor. See your health practitioner for guidance.
