Maintenance Calorie Calculator Based on BMI

The Maintenance Calorie Calculator is a simple and efficient tool to estimate your daily calorie needs based on your BMI, age, gender, weight, height, and activity level. Follow these steps to use the calculator effectively:

Step 1: Open the Calculator

Access the calculator in your browser by opening the HTML file. It is a lightweight, user-friendly interface that works on any modern device.

Step 2: Enter Your Details

1. Weight (kg): Input your current body weight in kilograms. Ensure the value is accurate for precise results.
2. Height (cm): Enter your height in centimeters. For example, if your height is 5'10", convert it to 178 cm before entering.
3. Age (years): Provide your current age in years. Age is essential as calorie needs decrease with age.
4. Gender: Select your gender (Male or Female). The calculator uses different formulas for men and women to determine basal metabolic rate (BMR).
5. Activity Level: Choose the activity level that best represents your daily routine:
   • Sedentary: Little to no exercise.
   • Lightly Active: Light exercise/sports 1–3 days a week.
   • Moderately Active: Moderate exercise/sports 3–5 days a week.
   • Very Active: Hard exercise/sports 6–7 days a week.

Step 3: Calculate

Click the "Calculate" button after entering all the details. The calculator will instantly process the data and display your maintenance calories on the same page.

Step 4: Interpret the Results

• Maintenance Calories: The result represents the number of calories you need daily to maintain your current weight, based on your lifestyle and activity level.
• Practical Usage: If you wish to lose weight, aim for a caloric deficit (consume fewer calories than your maintenance calories). If you wish to gain weight, aim for a caloric surplus (consume more calories than your maintenance calories).

Example

Suppose you are a 25-year-old male weighing 75 kg, standing 175 cm tall, and moderately active. Enter the following:

• Weight: 75 kg
• Height: 175 cm
• Age: 25 years
• Gender: Male
• Activity Level: Moderately Active

After clicking "Calculate," the result may show your maintenance calories as approximately 2,750 kcal/day.

Tips for Accurate Results

1. Use Reliable Measurements: Measure your weight and height accurately using a digital scale and a measuring tape.
2. Choose the Correct Activity Level: Overestimating your activity level may lead to inflated calorie estimates.
3. Recalculate Regularly: Update your weight, age, and activity level periodically to keep the results relevant.
