Body Mass Index (BMI) is an individual’s weight in kilograms divided by the square of height in meters. A high BMI can be a marker of high body heftiness. BMI can be utilized to evaluate for weight classes that may prompt medical issues i-e depression yet it isn’t indicative of the body heftiness or strength of a person.
The body mass index (BMI) is a measurement based on a person’s height and weight. It is calculated by taking the mass in kilograms and the height in metres and dividing by the square of the result. It is expressed in kilograms/metres, based on the mass in kilograms and the height in meters.

Body Mass Index Formula
The BMI Formula is: BMI = Weight (kg) / Height (m)².
It is possible to calculate BMI using a table or chart that shows BMI for different BMI categories as a function of mass and height as well as other units of measurement (converted to metric units for calculation).
According to their tissue mass (muscle, fat and bone) and height, people are categorized as underweight, normal weight, overweight, or obese based on their BMI. The major adult body mass indexes are underweight (under 18.5 kg/m2), normal weight (18.5 to 24.99 kg/m2), overweight (25 to 29.99 kg/m2) and obese (30 or more kg/m2).
The BMI has certain limitations that make it less useful than some of the other options for predicting an individual’s health rather than as a statistical measurement for groups, especially when applied to people with abdominal obesity, short stature, or unusually high muscle mass.
The risk of all-cause mortality increases as BMI approaches or surpasses the 20–25 range, with BMI under 20 and over 25 being associated with higher mortality. Nevertheless, ideal BMI ranges differ by race. For example, for Europeans, a BMI that is considered normal may be unsafe for Asians.

Categories
According to the BMI, someone’s weight deviates from a normal or desirable amount for one’s height when compared to their body weight. This is possible that body fat (adipose tissue) contributes to excess weight or deficiency, though other factors, such as muscularity, can also significantly affect BMI (see discussion below).
Adults with BMIs less than 18.5 are considered underweight and may be suffering from malnutrition, an eating disorder, or other health problems, while those with BMIs of 25 or greater are overweight, while those with BMIs more than 30 are considered obese.
Besides the international cut-off points set by the WHO (16, 17, 18.5, 25, 30, 35, and 40), four more cut-off points were set for Asians at risk (23, 27.5, 32.5, and 37.5). However, these cut-off points are only useful for statistical purposes.
| Category | BMI (kg/m2) | BMI Prime |
|---|---|---|
| Underweight (Severe thinness) | < 16.0 | < 0.64 |
| Underweight (Moderate thinness) | 16.0 – 16.9 | 0.64 – 0.67 |
| Underweight (Mild thinness) | 17.0 – 18.4 | 0.68 – 0.73 |
| Normal range | 18.5 – 24.9 | 0.74 – 0.99 |
| Overweight (Pre-obese) | 25.0 – 29.9 | 1.00 – 1.19 |
| Obese (Class I) | 30.0 – 34.9 | 1.20 – 1.39 |
| Obese (Class II) | 35.0 – 39.9 | 1.40 – 1.59 |
| Obese (Class III) | ≥ 40.0 | ≥ 1.60 |

BMI Critera in Armed Forces
The BMI criteria for the Pakistan Armed Forces are based on the international standards set by the World Health Organization (WHO). The WHO defines four categories of BMI: underweight (below 18.5), normal weight (18.5-24.9), overweight (25-29.9), and obese (30 or above). These categories are associated with different levels of health risk and mortality.
There has also been a finding that soldiers with very low BMI have a higher injury rate regardless of their physical fitness level. This finding highlights the risks associated with being underweight and the importance of preventing excess dieting and weight loss during weight control efforts.

International Variations
The recommended linear scale distinctions may vary over time and country to country, leading to problems in global, longitudinal surveys. surveys.
As BMI, percentage of body fat, and health risks vary among different populations, people with BMIs below the WHO cut-off for overweight, 25 kg/m2, have an increased risk of type 2 diabetes mellitus and atherosclerosis cardiovascular disease; however, the cut-off for observed risk differs among different populations. European, Asian, and African populations and subpopulations differ in their observed risk cut-offs.

Importance of BMI in Armed Forces
In the Pakistan Armed Forces, BMI is one of the criteria for physical fitness and medical tests. The normal BMI value is between 18.5-24.9, so a candidate should measure his height and weight to determine his BMI.
BMI is important for the Pakistan Armed Forces because it reflects the physical readiness and health status of the soldiers. A healthy weight can improve the performance, endurance, and stamina of the soldiers in various tasks and missions. Furthermore, it can reduce the risks of injuries, illnesses, and fatigue that could compromise soldiers’ safety and effectiveness.
However, BMI is not a perfect measure of health or fitness. It does not take into account the muscle mass, bone density, or body shape of the individual. Some people may have a high BMI but a low body fat percentage, or vice versa.
Therefore, BMI should be viewed as a screening tool rather than a diagnostic tool. Furthermore, other factors should be considered when evaluating the health and fitness of the soldiers, including waist circumference, blood pressure, blood sugar levels, cholesterol levels, and physical activity levels.
Bottom line
BMI is an important indicator of body fat and health risk in the Pakistan Armed Forces. It can help identify candidates who are fit for service and monitor their weight status over time. However, BMI is not the only factor that matters for health and fitness. A balanced diet, regular exercise, and medical check-ups are also essential for maintaining a healthy weight and preventing diseases.
