About Calorie Calculator
A calorie calculator helps you determine your daily calorie needs based on your Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE). It helps you plan your diet for weight loss, maintenance, or weight gain.
Key Terms
- BMR: Calories burned at rest for basic functions
- TDEE: Total calories burned including activity
- Weight Loss: TDEE minus 500 calories (0.5 kg/week loss)
- Weight Gain: TDEE plus 500 calories (0.5 kg/week gain)
Frequently Asked Questions
BMR (Basal Metabolic Rate) is the number of calories your body burns at rest to maintain basic functions like breathing, circulation, and cell production. It accounts for 60-70% of daily calorie burn.
TDEE (Total Daily Energy Expenditure) is the total calories you burn in a day, including BMR, physical activity, and digestion. It represents your total daily calorie needs.
To lose weight, create a calorie deficit of 500-1000 calories per day. This typically results in 0.5-1 kg weight loss per week. Never go below 1200 calories (women) or 1500 calories (men) without medical supervision.
BMR is affected by age, gender, height, weight, muscle mass, and genetics. Men typically have higher BMR than women. BMR decreases with age and increases with muscle mass.
