About Calorie & Macro Calculation

How It Works:

This calculator uses the Mifflin-St Jeor equation to estimate your BMR (Basal Metabolic Rate), then multiplies it by your activity level to get your TDEE (Total Daily Energy Expenditure). Based on your goal, it adjusts calories and calculates macronutrient distribution.

Calorie Adjustments by Goal:

  • Extreme Loss: -1000 cal/day (1 kg/week loss)
  • Weight Loss: -500 cal/day (0.5 kg/week loss)
  • Mild Loss: -250 cal/day (0.25 kg/week loss)
  • Maintain: TDEE (no change)
  • Mild Gain: +250 cal/day (0.25 kg/week gain)
  • Weight Gain: +500 cal/day (0.5 kg/week gain)

Macronutrient Ratios:

  • Balanced: 30% Protein, 40% Carbs, 30% Fats
  • Low Fat: 30% Protein, 50% Carbs, 20% Fats
  • Low Carb: 40% Protein, 20% Carbs, 40% Fats
  • High Protein: 40% Protein, 30% Carbs, 30% Fats
  • Keto: 30% Protein, 5% Carbs, 65% Fats

Calorie Content:

  • Protein: 4 calories per gram
  • Carbohydrates: 4 calories per gram
  • Fats: 9 calories per gram

Important Notes:

  • These are estimates - individual needs vary based on metabolism, genetics, and other factors
  • Extreme calorie restriction can be harmful - consult a healthcare professional
  • For sustainable results, aim for gradual changes (0.5-1 kg per week)
  • Focus on whole foods and balanced nutrition, not just calorie counting
  • Adjust based on your progress and how you feel
  • Consider consulting a registered dietitian for personalized advice
