1. What is the Daily Calorie Calculator?

The Daily Calorie Calculator estimates your total daily energy expenditure (TDEE) based on your basal metabolic rate (BMR) and activity level. It helps determine how many calories you need to maintain your current weight.

2. How Does the Calculator Work?

The calculator uses the Mifflin-St Jeor Equation for BMR:

Then multiplies BMR by your activity factor to get daily calories:

Activity Factors:

• 1.2 - Sedentary (little or no exercise)
• 1.375 - Lightly active (light exercise 1-3 days/week)
• 1.55 - Moderately active (moderate exercise 3-5 days/week)
• 1.725 - Very active (hard exercise 6-7 days/week)
• 1.9 - Extra active (very hard exercise & physical job)

3. Importance of Calorie Calculation

Details: Knowing your daily calorie needs helps with weight management, whether your goal is to maintain, lose, or gain weight. It provides a scientific basis for meal planning.

4. Using the Calculator

Tips: Enter your age in years, select gender, enter weight in kg, height in cm, and choose your activity level. For accurate results, measure your weight and height precisely.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides a good estimate for most people, but individual variations in metabolism can affect actual calorie needs.

Q2: Should I eat fewer calories to lose weight?
A: A moderate reduction (300-500 kcal/day) below maintenance is recommended for sustainable weight loss.

Q3: Does muscle mass affect BMR?
A: Yes, muscle burns more calories at rest than fat. People with more muscle mass typically have higher BMR.

Q4: How often should I recalculate my needs?
A: Recalculate after significant weight changes (±5 kg) or changes in activity level.

Q5: Can this be used for children?
A: This calculator is designed for adults. Children have different calorie needs due to growth.
