1. What is BMI and TDEE?

Body Mass Index (BMI) is a measure of body fat based on height and weight. TDEE (Total Daily Energy Expenditure) represents the total number of calories you burn in a day, including basal metabolic rate and physical activity.

2. How Does the Calculator Work?

The calculator uses the following formulas:

Where:

• \( weight \) — Body weight in kilograms (kg)
• \( height \) — Height in meters (m)
• \( TDEE \) — Total Daily Energy Expenditure in kcal/day

Explanation: BMI provides a simple numeric measure of a person's thickness or thinness, while TDEE represents your daily calorie needs for weight maintenance.

3. Importance of BMI and Calorie Calculation

Details: Understanding your BMI helps assess weight-related health risks. Knowing your TDEE is essential for weight management, whether your goal is to lose, maintain, or gain weight.

4. Using the Calculator

Tips: Enter weight in kilograms, height in meters, and your estimated TDEE. All values must be positive numbers. For accurate results, measure your weight and height carefully.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy BMI range?
A: For adults, a BMI between 18.5 and 24.9 is considered healthy. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.

Q2: How do I calculate my TDEE?
A: TDEE can be estimated using formulas that consider your basal metabolic rate (BMR) multiplied by an activity factor. Many online calculators can help estimate your TDEE.

Q3: Does BMI work for athletes?
A: BMI may overestimate body fat in athletes and others with high muscle mass, as muscle weighs more than fat.

Q4: Should I eat exactly my TDEE?
A: To maintain weight, eat around your TDEE. To lose weight, create a calorie deficit (eat less than TDEE). To gain weight, create a surplus (eat more than TDEE).

Q5: How often should I recalculate these values?
A: Recalculate BMI if your weight changes significantly. Recalculate TDEE if your activity level, weight, or body composition changes.
