📖 Understanding Daily Calorie Needs

Calories are units of energy that your body needs to function. Knowing your daily calorie requirement is essential for weight management - whether you want to lose, gain, or maintain weight. Our calculator uses the scientifically validated Mifflin-St Jeor equation.

BMR (Basal Metabolic Rate) is the calories your body burns at complete rest for basic functions like breathing, blood circulation, and cell repair. TDEE (Total Daily Energy Expenditure) is your BMR multiplied by your activity level, giving your total daily calorie burn.

For weight loss, create a deficit of 500 calories per day to lose about 0.5 kg per week. For weight gain, add 500 calories surplus. Remember, 1 kg of body weight equals approximately 7,700 calories. Crash dieting below your BMR can slow metabolism and harm health.

Beyond calories, focus on nutrition quality - protein for muscle, healthy fats, complex carbs, and plenty of vegetables. Combine diet with regular exercise for best results. Always consult a nutritionist for personalized advice.
