Calorie Calculator

What is Calorie Calculator?

The Calorie Calculator estimates daily caloric requirements to maintain, lose, or gain weight. Calculate your Basal Metabolic Rate (BMR) and daily energy expenditure based on age, gender, height, weight, and activity level.

How Does Calorie Calculator Work?

It calculates BMR using standard formulas (Mifflin-St Jeor or Harris-Benedict) and multiplies it by activity factors to determine Total Daily Energy Expenditure (TDEE) client-side.

How to Use Calorie Calculator — Step by Step

1. Select gender and enter age.
2. Enter weight and height (supports metric and imperial).
3. Select daily physical activity level (sedentary to highly active).
4. Review daily calorie targets for maintenance, weight loss, or weight gain.

Key Benefits

• TDEE Calculation: Accounts for physical activity to provide realistic daily targets.
• Weight Goal Slabs: Clearly shows calorie counts needed for weight loss or muscle building.
• Private Health Data: No fitness details are saved on servers.

Who Uses Calorie Calculator?

• Diet Planning: Calculate daily calorie intake limits before drafting meal plans.
• Fitness Goals: Track BMR changes as weight and activity levels adjust.

Tips & Best Practices

• For safe, sustainable weight loss, aim for a modest deficit of 300-500 calories below your TDEE.
• Re-calculate calorie needs every 5-10 lbs of weight change, as your BMR adjusts with mass.

Common Mistakes to Avoid

• Overestimating daily physical activity level, which leads to target calorie values that are too high.
• Following extreme calorie deficits (under 1200 calories for women, 1500 for men) without medical supervision.
