BMI Formula

Body Mass Index (BMI) is calculated as:

$$BMI = \frac{\text{Weight (kg)}}{\text{Height (m)}^2}$$

Weight in kilograms (kg), Height in meters (m).

BMR Calculator

Calculate your Basal Metabolic Rate (BMR), the calories your body needs to function at rest.

BMR Formula (Mifflin-St Jeor)

This widely used formula estimates your daily caloric needs at rest:

For Men: $$BMR = (10 \times \text{weight in kg}) + (6.25 \times \text{height in cm}) - (5 \times \text{age in years}) + 5$$
For Women: $$BMR = (10 \times \text{weight in kg}) + (6.25 \times \text{height in cm}) - (5 \times \text{age in years}) - 161$$

Underweight Illustration

Underweight

A BMI below 18.5 indicates you might be underweight, which can sometimes lead to nutritional deficiencies or weakened immune function.

Healthy Weight Illustration

Healthy Weight

A BMI between 18.5 and 24.9 is considered healthy, generally associated with lower risks of chronic diseases and overall well-being.

Overweight Illustration

Overweight

A BMI between 25.0 and 29.9 suggests you are overweight, which increases the risk of heart disease, type 2 diabetes, and other health issues.

Obese Illustration

Obese

A BMI of 30.0 or higher indicates obesity, carrying significant health risks including severe cardiovascular problems and metabolic disorders.

Understanding Your Health Metrics: BMI & BMR Insights

The Role of BMI in Health Assessment

BMI is a quick screening tool to categorize individuals based on their weight and height. It helps identify potential weight-related health risks.

  • Healthy BMI (18.5-24.9): Associated with lower risks of chronic diseases like heart disease, diabetes, and certain cancers. Often correlates with better energy and mobility.
  • Underweight (<18.5) or Overweight/Obese (>24.9): May indicate potential health concerns, including nutritional deficiencies, weakened immune system, cardiovascular issues, or increased risk of joint problems.

Understanding Your BMR & Energy Needs

BMR represents the minimum calories required for your body's basic functions at rest. It's a crucial component for understanding your overall daily energy expenditure.

  • Personalized Calorie Goals: Your BMR helps determine your Total Daily Energy Expenditure (TDEE) when combined with your activity level. This is vital for weight management.
  • Metabolic Health Indicator: A higher BMR generally means your body burns more calories at rest, often associated with higher muscle mass.
