Coronavirus Weight Risk Calculator

Coronavirus's effects on the eldery and obese

Individuals over 65 years with compromised immune systems are at the highest risk of being hospitalized and dying from COVID-19.

Emergency Room doctors have now noted that obese individuals (particularly individuals with high BMI) are at equally greater risk of being hospitalized and dying from contracting COVID-19 - regardless of age.

As COVID-19 is primarily a respiratory disease, individuals with high BMI may already suffer from sleep apnea, breathing problems, and decreased chest function due to weight on the chest.

It is recommended that these individuals stay extra cautious during these troubled times. For example, wearing a mask while travelling outside and minimizing interactions with the public. For more information, please read his article.

Looking for a simple body fat % calculator?

This military calculator can measure your total body fat percentage, lean body mass, fat body mass and BMI.

We built this calculator for ourselves as we wanted a quick and easy way to determine our own body fat percentage

We believe in our calculator so much so that we'll return the $4.99 we charge for 3 estimations if you are unsatisfied with the result.

  • U.S. System Metric System

BMI is a simple measurement based on your height and weight to determine if you are underweight, normal weight, overweight or obese. BMI does not measure body fat percentage directly but has shown to moderately correlate with other methods of body fat measurement.

It is a rudimentary measurement and can vary significantly depending on age, distribution of muscle mass, bone density and fat mass. The BMI calculation does not take ethnic body differences into account. It should be taken as a rule of thumb rather than the perfect determination of your overall health.

The World Health Organization has the following breakdown for BMI Categories:
Category BMI (FROM) BMI (TO)
Very severely underweight - 15
Severely underweight 15 16
Underweight 16 18.5
Normal (healthy weight) 18.5 25
Overweight 25 30
Obese Class I (Moderately obese) 30 35
Obese Class II (Severely obese) 35 40
Obese Class III (Very severely obese) 40 45
Obese Class IV (Morbidly obese) 45 50
Obese Class V (Super obese) 50 60
Obese Class VI (Hyper obese) 60+

What is the Body Fat Calculator Based On?

The Body Fat Calculator is based on equations developed by James A. Hodgdon and Marcie B. Beckett at the U.S. Naval Health Research Center in 1984 and involves measuring height and the circumference of the neck, waist, and hips (only for women) and plugging the data into an equation (different for men and women) to determine total body fat percentage. Details on the equations can be found here.

Included below are the cut-off body fat percentages for the different age groups and sexes in the U.S. Army, U.S. Marine, and U.S. Navy Corp.

The Department of Deference has set a minimum goal of 18% body fat percentage for men and 26% for women.

Instructions for Body Part Measurement

General: It is best to take multiple measurements and average them out before putting the numbers into the body fat calculator. For a more accurate assessment, ask someone else to take your measurements.

Height: It is important to be still, stand barefoot and look ahead during measurement.

Neck: Stay relaxed, look ahead and get the measurement of the circumference of the neck at a point just below Adam’s apple (larynx).

Waist: Look straight ahead, keep your arms placed at your side and do not suck in your gut. Measure the circumference of the belly around the navel.

Hip: Feet must be placed close together and the measurement must include the largest circumference of the hips.

The calculator above includes settings for the Metric System as well as the U.S. Customary System.
