What is BMI?
Maintaining a healthy weight is vital for our health and keeps diseases at bay. Did you know that one of the simplest ways to assess your weight status is by calculating your Body Mass Index (BMI)? BMI is a key metric that determines if you fall within a healthy weight range on the basis of your height and weight. BMI assesses the body fat. We, at Bhrungi Hospitals, will help you to explore what exactly is BMI, and how does it help you determine if you’re overweight or obese?
Calculating BMI
The formula for calculating BMI is:
BMI = weight (kg) / height (m²)
For example, if you weigh 70 kg and your height is 1.7 meters, your BMI would be:
BMI = 70 / (1.7 × 1.7) = 24.2
BMI Categories
The BMI thus calculated (as shown above) falls into one of the following categories.
- Underweight: BMI less than 18.5
- Normal weight: BMI between 18.5 and 24.9
- Overweight: BMI between 25 and 29.9
- Obese: BMI 30 or higher
Within the obese category, there are further classifications:
- Obese Class I: 30 to 34.9
- Obese Class II: 35 to 39.9
- Obese Class III (Morbid Obesity): 40 or higher
Please note that these are general guidelines to help you understand whether you are at any risk of health complications or not. BMI is not a diagnostic tool but it’s an important point to begin with.
4 Key Limitations of BMI
BMI is not an exact value; it has some limitations such as the following –
- Muscle mass: Athletes with high muscle mass may have a high BMI but not excess body fat.
- Age: Older adults may have a higher BMI due to changes in body composition.
- Gender: Women tend to have more body fat than men.
- Ethnicity: Some ethnic groups may have different body fat distributions.
Therefore, BMI should not be considered as a distinct unit. BMI should be considered along with other assessments, after a thorough medical evaluation.
Further elaborating on the above-mentioned points, let’s say for instance, that if your BMI is 25 or above, according to the BMI categories, you fall into the overweight or obese category. However, always remember that BMI is just one indicator but not the sole determinant. Athletes, for example, may have a high BMI due to muscle mass but not have excess body fat. It is advisable to consult a healthcare professional first whereby other factors will also be taken into consideration, like muscle mass, body composition, and overall lifestyle.
4 Signs you may be Overweight or Obese
- Abdominal Fat: Excess fat around the abdomen is a significant factor for health risks. Measure your waist size around the navel. A waist size of over 35 inches in women and 40 inches in men suggests a higher risk of obesity-related diseases.
- Physical Activity: Shortness of breath, struggling with stamina, or experiencing joint pain can be signs of excessive weight.
- Higher Health Risks: Being overweight or obese increases the risk of heart disease, diabetes, high blood pressure, and other health conditions.
- Sleep Issues: Excess weight can contribute to frequent fatigue, sleep apnea and snoring.
These signs are mere indications. For a comprehensive assessment please consult your trusted healthcare professional. A doctor shall develop a personalized weight management plan for you based on your physical exam, blood tests and medical history.
