How Does Our Calorie Calculator Work?

Our calculator follows a simple three-step process:

1️⃣ Data Entry
Age 🧠 Define your basal metabolism.
Weight ⚖️ Influences the energy your body requires.
Height 📏 Affects basal caloric expenditure.
Sex 🔍 Determine the appropriate formula for the calculation.
Activity level 🏃 Indicates how many additional calories you need.

Why is it important?
Each person has a unique metabolism. This data allows you to accurately customize your daily calorie calculation.

2️⃣ Automatic Calculation
We use the following standard formula to calculate your calorie requirement:
📐 Mifflin-St Jeor Formula:
Men: (10 × weight) + (6.25 × height) – (5 × age) + 5
Women: (10 × weight) + (6.25 × height) – (5 × age) – 161
👉 Then multiply by the TDEE Factor (depending on your activity level)

The result will give you the exact number of calories you need to consume per day.

3️⃣ Results and Recommendations
🔹 If the result is high, you can focus on maintaining your energy or losing weight with a small deficit.
🔹 If the result is low, you should make sure you are meeting your minimum needs to avoid fatigue or malnutrition.
