BMI, which stands for Body Mass Index, is a number calculated from a person's weight and height. BMI provides a reliable indicator of body fat for most people and is used to screen for weight categories that could potentially impact health, including fertility issues.
Check your BMI quickly using our Body Mass Index calculator. Find out if you are underweight, normal, obese or overweight. Body Mass Index (BMI) is an indication of the amount of fat in a person's body based on the ratio of body weight compared to a person's height. There's another, more precise way to estimate body fat that's both simpler and more accurate than BMI. It's called Relative Fat Mass (RFM). The Body Mass Index (BMI) value tells whether a person is thin/underweight, normal/ideal weight, obese/overweight.
Body Mass Index (BMI) is an indication of the amount of fat in a person's body based on the ratio of body weight compared to a person's height. It is a widely used tool to determine a person's optimal body weight and can provide insights into the relationship between obesity and immune system health. The higher the BMI, the greater the level of fat in a person's body, which can impact the functioning of the immune system. Due to its simplicity in calculation, BMI is commonly utilized as a tool to determine a person's optimal body weight.

BMI, or Body Mass Index, is typically divided into four categories that help to classify an individual's weight in relation to their height. The BMI categories are as follows:
Underweight: A BMI below 18.5 is considered underweight. This category indicates that a person's weight is lower than what is considered healthy for their height. Being underweight can be associated with health risks, such as nutritional deficiencies and a weakened immune system.
Normal Weight (ideal/superior weight): A BMI between 18.5 and 24.9 falls within the normal weight range. Individuals in this category typically have a weight that is considered healthy for their height. It suggests that they are at a lower risk of certain weight-related health issues.
Overweight: A BMI between 25.0 and 29.9 falls into the overweight category. This indicates that a person's weight is higher than what is considered healthy for their height. Overweight individuals may be at an increased risk of health problems like heart disease, diabetes, and joint issues.
Obese (Obesity): A BMI of 30.0 or higher is classified as obesity. This category signifies that a person has a significantly higher body weight relative to their height, and it is associated with a greater risk of serious health conditions, including type 2 diabetes, heart disease, hypertension, and cancers. Mainly, lack of sleep causes obesity by disrupting the body's hormonal balance and increasing cravings for high-calorie foods. So, it is important to address sleep quality and duration as a crucial factor in managing and preventing obesity, highlighting the interconnectedness of lifestyle choices and overall health.
|18.5 - 24.9||Normal (ideal/superior weight)|
|25.0 - 29.9||Overweight|
|30.0 and above||Obese (Obesity)|
To calculate Body Mass Index (BMI) manually, use the following formula:
Body Mass Index = Wt (in kilograms) / [Ht (in meters)]2
Body Mass Index = Wt (in pounds) / [Ht (in inches)]2 x 703
Note: The BMI calculation mentioned above is appropriate for evaluating adult men and women aged 18 to 64. It's not recommended for use by children, infants, pregnant or breastfeeding women, individuals with high muscle mass (like athletes or bodybuilders), and older adults who may have experienced muscle loss.
BMI takes into consideration your height and weight to categorize you into a weight range. However, the BMI calculator is unable to differentiate between fat and muscle. If you have a significant amount of muscle, which is denser than fat, you might find yourself classified as overweight or obese based on your BMI result. The BMI calculator is also unable to determine if you’re pregnant, so it's advisable to check in with your doctor or healthcare professionals if you have any concerns about your weight.
Additionally, childhood obesity, which is a growing concern worldwide, can also be inaccurately assessed using the BMI calculator, as it does not account for factors such as body composition and the unique growth patterns of children.
