1. What is a Calorie Calculator & How Does It Work?

A calorie calculator is a digital tool that estimates the number of calories you need daily to maintain, lose, or gain weight. It uses scientific formulas, such as the Mifflin-St Jeor Equation, to provide personalized results.

How It Calculates Your Needs:

1. Basal Metabolic Rate (BMR) – Calories burned at rest.

2. Activity Level – Sedentary, lightly active, moderately active, very active.

3. Weight Goals – Adjusts calories for cutting, bulking, or maintenance.

Why Use One?

✔ Prevents guesswork in diet planning.
✔ Helps avoid overeating or undereating.
✔ Optimizes fitness results (fat loss, muscle gain).

2. Key Factors Affecting Your Daily Calorie Needs

A. Age & Gender

• Men generally need more calories due to higher muscle mass.

• Women may require fewer calories but need adjustments for hormonal changes.

• Metabolism slows with age, so calorie needs decrease.

B. Weight & Height

• Heavier individuals burn more calories at rest.

• Taller people have higher BMRs due to greater body surface area.

C. Activity Level (TDEE - Total Daily Energy Expenditure)

Activity Level	Multiplier	Description
Sedentary	1.2	Little to no exercise
Lightly Active	1.375	Light exercise 1-3 days/week
Moderately Active	1.55	Moderate exercise 3-5 days/week
Very Active	1.725	Hard exercise 6-7 days/week
Extremely Active	1.9	Physical job + daily training

D. Weight Goals

• Weight Loss: Reduce intake by 300-500 calories/day.

• Weight Gain: Increase by 300-500 calories/day.

• Maintenance: Match calorie intake to TDEE.

3. How to Use a Calorie Calculator for Weight Loss, Gain & Maintenance

Step 1: Enter Your Stats

• Gender, Age, Weight (kg/lbs), Height (cm/ft).

Step 2: Select Activity Level

• Choose between sedentary to extremely active.

Step 3: Set Your Goal

• Lose weight? Subtract calories.

• Gain muscle? Add calories.

• Maintain? Stick to calculated TDEE.

Example Calculation:

A 30-year-old woman, 165 cm tall, 60 kg, moderately active, wants to lose weight.

• BMR = 1,330 calories

• TDEE = 1,330 × 1.55 = 2,061 calories/day

• Weight Loss Target = 2,061 - 500 = 1,561 calories/day

4. The Role of BMR (Basal Metabolic Rate) in Calorie Calculation

What is BMR?

• Calories burned at complete rest for vital functions (breathing, digestion).

How to Calculate BMR:

Mifflin-St Jeor Formula:

• Men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5

• Women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161

Why BMR Matters:

• Determines minimum calorie needs.

• Helps avoid extreme dieting mistakes.

5. Why Water Intake Matters in Your Diet Plan

The Link Between Hydration & Calories

• Water suppresses appetite (reduces overeating).

• Boosts metabolism by 24-30% for 1-1.5 hours.

• Prevents false hunger signals (thirst vs. hunger).

How Much Water Should You Drink?

• General Rule: 30-35 ml per kg of body weight.

• Example: A 70 kg person needs 2.1-2.5 liters/day.
