1. What is BMR and Macros Calculation?

BMR (Basal Metabolic Rate) represents the number of calories your body needs to perform basic life-sustaining functions. Macros (macronutrients) refer to the protein, carbohydrates, and fats that make up your diet and provide energy.

2. How Does the Calculator Work?

The calculator uses the following equations:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in centimeters
• \( age \) — Age in years
• \( activity \) — Activity level multiplier

Explanation: The BMR equation estimates your basal metabolic rate, while the protein calculation determines daily protein needs based on 25% of your total daily energy expenditure.

3. Importance of BMR and Macros Calculation

Details: Understanding your BMR helps in creating effective weight management plans, while tracking macros ensures proper nutrient balance for health and fitness goals.

4. Using the Calculator

Tips: Enter your weight in kg, height in cm, age in years, and select your activity level. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between BMR and TDEE?
A: BMR is the calories burned at complete rest, while TDEE (Total Daily Energy Expenditure) includes all daily activities and exercise.

Q2: Why calculate protein intake?
A: Protein is essential for muscle repair, immune function, and satiety. Adequate protein intake supports muscle maintenance during weight loss.

Q3: How accurate is the BMR calculation?
A: This provides an estimate. Individual variations in metabolism, body composition, and other factors can affect actual energy needs.

Q4: Should I adjust my macros for specific goals?
A: Yes, macros may need adjustment based on whether your goal is weight loss, muscle gain, or maintenance.

Q5: How often should I recalculate my BMR and macros?
A: Recalculate every 4-6 weeks or when your weight changes significantly, activity level changes, or you reach new fitness goals.
