What are Calories?
Calories are units of energy that measure how much energy food provides to your body. Your daily calorie needs depend on your age, weight, height, gender, and activity level. Understanding your calorie requirements is essential for weight management and fitness goals.
BMR vs TDEE Explained
BMR (Basal Metabolic Rate): The number of calories your body burns at rest, just maintaining basic functions like breathing, circulation, and cell production. This is typically 60-75% of your total daily energy expenditure.
TDEE (Total Daily Energy Expenditure): The total calories you burn daily, including BMR plus calories burned through activity and exercise. This is your "maintenance" calorie level.
Activity Level Multipliers
- Sedentary (1.2): Little or no exercise, desk job
- Lightly Active (1.375): Light exercise 1-3 days per week
- Moderately Active (1.55): Exercise 3-5 days per week
- Very Active (1.725): Exercise 6-7 days per week
- Extremely Active (1.9): Physical job or intense daily training
Weight Management Goals
Weight Loss: Create a calorie deficit of 500 calories per day to lose approximately 0.5 kg (1 lb) per week. Never go below 1200 calories per day without medical supervision.
Weight Gain: Create a calorie surplus of 500 calories per day to gain approximately 0.5 kg per week. Focus on nutrient-dense foods, not just calories.
Nutrition Tips
- Track your food intake to understand your actual calorie consumption
- Focus on whole foods: vegetables, fruits, lean proteins, whole grains
- Protein is essential for muscle maintenance and recovery
- Don't drastically cut calories - gradual changes are sustainable
- Consult a nutritionist for personalized advice
Frequently Asked Questions
Is BMR the same as metabolism?▼
BMR is part of your metabolism. Your metabolism includes BMR plus the calories burned through digestion and activity. BMR is typically 60-75% of your total metabolism.
How accurate is this calculator?▼
This calculator uses the Mifflin-St Jeor formula, which is one of the most accurate methods. However, individual results vary based on metabolism, muscle mass, and other factors. Use this as a starting point and adjust based on real-world results.
Can I lose weight by just eating less?▼
Yes, weight loss comes from consuming fewer calories than you burn. However, combining calorie deficit with exercise and proper nutrition is more effective and healthier than diet alone.
What's the minimum calorie intake?▼
Most experts recommend not going below 1200 calories per day for women or 1500 for men without medical supervision. Extreme calorie restriction can harm your metabolism and health.
Understanding Your Results
BMR: Calories your body burns at rest. This is the minimum energy needed for basic functions.
TDEE: Total calories burned including exercise and daily activities. This is your maintenance calorie level.
Weight Loss: Eat 500 calories less than TDEE to lose ~0.5 kg per week.
Weight Gain: Eat 500 calories more than TDEE to gain ~0.5 kg per week.
