🧠 Calorie Calculator – Understand Your Daily Calorie Needs

The Calorie Calculator is a smart and easy-to-use online tool designed to help you estimate how many calories your body needs each day to maintain, lose, or gain weight. Whether your goal is to shed extra pounds, build muscle, or simply understand your body’s energy requirements, this calculator provides accurate results using the scientifically validated Mifflin-St Jeor Equation.

Your body burns calories every day — even when you’re not exercising. The number of calories burned while resting is known as your Basal Metabolic Rate (BMR). When you add physical activity, work, and lifestyle habits to that equation, you get your Total Daily Energy Expenditure (TDEE). Knowing both of these values is the foundation of any successful nutrition or fitness plan.

This calculator combines all these factors to give you personalized calorie targets based on your age, gender, height, weight, and activity level. Once you choose your goal (lose, maintain, or gain weight), it instantly generates your daily calorie recommendation and provides a detailed summary of your results.

⚙️ How the Calorie Calculator Works

The calculator uses the Mifflin-St Jeor Formula, one of the most reliable methods for estimating daily energy requirements.
Here’s how it works step-by-step:

1. BMR (Basal Metabolic Rate):
   This is the number of calories your body burns to maintain vital functions — breathing, digestion, and circulation — while at rest.

   Formula:

   • For men: BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age + 5

   • For women: BMR = 10 × weight (kg) + 6.25 × height (cm) – 5 × age – 161

2. TDEE (Total Daily Energy Expenditure):
   Your BMR is multiplied by an activity factor that reflects how active you are:

   • Sedentary (little or no exercise): 1.2

   • Lightly active (1–3 days/week): 1.375

   • Moderately active (3–5 days/week): 1.55

   • Very active (6–7 days/week): 1.725

   • Extra active (intense training or physical job): 1.9

3. Goal Adjustment:
   Based on your selected goal:

   • To lose weight, the calculator subtracts 500 calories (approx. 0.5 kg fat loss per week).

   • To gain weight, it adds 500 calories (approx. 0.5 kg gain per week).

   • To maintain weight, it keeps the TDEE unchanged.

💡 Why Use a Calorie Calculator?

Tracking calories manually can be confusing and time-consuming. Our Calorie Calculator eliminates the guesswork by giving you instant, science-based results. It helps you:

• Create a calorie-balanced meal plan

• Manage your weight effectively

• Improve workout performance

• Understand your body’s metabolism

• Set realistic health and fitness goals

Whether you’re a beginner or a professional athlete, understanding your caloric intake is crucial. Too many calories lead to weight gain, while too few can slow down your metabolism and energy levels. By using this tool, you can find the perfect balance that suits your unique needs.

🥗 What to Do After Calculating Your Calories

Once you know your daily calorie goal, the next step is to adjust your diet and activity accordingly:

• For Weight Loss: Focus on a calorie deficit through healthy eating and regular exercise. Include high-protein foods, fruits, vegetables, and whole grains.

• For Muscle Gain: Increase calorie intake with nutritious, high-protein foods. Strength training and progressive overload help convert those extra calories into muscle.

• For Maintenance: Maintain a balanced diet with consistent activity to keep your current weight stable.

Tracking your results weekly can help you fine-tune your plan for steady progress. Remember, small and consistent changes lead to long-term success.
