Understanding Your Calorie Needs
What is BMR?
Basal Metabolic Rate (BMR) is the number of calories your body burns at rest just to maintain vital functions like breathing, circulation, and cell production. This is the minimum calories you need even if you do nothing all day.
What is TDEE?
Total Daily Energy Expenditure (TDEE) is your BMR multiplied by your activity level. This represents the total calories you burn in a day, including all activities and exercise.
Macronutrients
- Protein (30%): 4 calories per gram. Essential for muscle repair and growth.
- Carbohydrates (40%): 4 calories per gram. Primary energy source for your body and brain.
- Fats (30%): 9 calories per gram. Important for hormone production and nutrient absorption.
Weight Loss Tips
- Aim for sustainable loss of 0.5-1 kg (1-2 lbs) per week
- Don't go below 1200 calories (women) or 1500 calories (men)
- Combine calorie deficit with regular exercise
- Track your food intake and adjust as needed
- Prioritize protein to preserve muscle mass
Frequently Asked Questions
How accurate is this calorie calculator?
This calculator uses the Mifflin-St Jeor equation, which is considered one of the most accurate formulas for estimating BMR. However, individual metabolism can vary by 10-15%. Use this as a starting point and adjust based on your actual results over 2-4 weeks.
Should I eat exactly the calories calculated?
Use the calculated calories as a starting point. Track your weight for 2-4 weeks and adjust if needed. If you're not losing/gaining weight as expected, adjust by 200-300 calories. Individual metabolism, activity levels, and other factors can affect your actual calorie needs.
What's the difference between BMR and TDEE?
BMR (Basal Metabolic Rate) is the calories your body burns at rest for basic functions. TDEE (Total Daily Energy Expenditure) is your BMR multiplied by your activity level, representing total calories burned per day. TDEE is what you should use for diet planning.
How fast should I lose weight?
Safe and sustainable weight loss is 1-2 pounds per week (0.5-1% of body weight). This requires a deficit of 500-1000 calories per day. Faster weight loss can lead to muscle loss, nutritional deficiencies, and is harder to maintain. Slow and steady wins the race.
Do I need to count calories to lose weight?
Counting calories isn't mandatory but it helps create awareness and accountability. Some people succeed with intuitive eating, portion control, or other methods. However, tracking calories for at least a few weeks can teach you about portion sizes and help identify areas for improvement.
Should I adjust my macros for my goals?
Yes! For weight loss, higher protein (30-35%) helps preserve muscle and increases satiety. For muscle gain, aim for 1.6-2.2g protein per kg body weight. For endurance athletes, increase carbs to 50-60%. The calculator provides balanced ratios, but adjust based on your specific goals and how you feel.
