*BMI (Body Mass Index) means a number that shows whether your weight is healthy for your height.* It’s calculated using your weight and height to quickly check if you're underweight, normal, overweight, or obese. .Body Mass Index (BMI) is a simple calculation using a person's height and weight. The formula - BMI = kg/m² where kg is a person's weight in kilograms and m² is their height in meters squared. BMI provides a reliable indicator of body fatness for most people and is used to screen for weight categories that may lead to health problems.BMI works by using your weight and height to estimate whether your body weight is healthy.
BMI is partly accurate, but not perfect. It gives a quick idea of whether your weight is healthy, but it doesn’t measure body fat or muscle. So BMI can be misleading for: Muscular people (looks “overweight” even if they’re healthy) Very lean people (normal BMI but low muscle, high fat) Different body types or ethnic groups BMI is useful for a general check, but not fully accurate for individual health.
What Your Body Weight Says About Your Health [bold] Understand how your BMI affects your health. Learn the risks of low and high BMI, including heart disease, diabetes, weak immunity, and nutrient deficiency. Short Brief: Body Mass Index (BMI) is a simple way to check if your weight is healthy for your height. A low BMI increases risks like nutrient deficiency, weak immunity, and bone loss. A high BMI raises the chances of heart disease, diabetes, high blood pressure, and joint problems. BMI doesn’t measure body fat directly, but it’s a strong early signal of health risks and helps you take action before serious issues appear.
