Informazioni su questo strumento

This calories calculator helps you determine your daily calorie requirements using the scientifically validated Mifflin-St Jeor equation. Simply enter your age, gender, weight, height, activity level, and fitness goal to get personalized results. The tool calculates your Basal Metabolic Rate (BMR) and adjusts it based on your activity level to provide your Total Daily Energy Expenditure (TDEE). It then recommends daily calorie intake for your selected goal (weight loss, maintenance, or muscle gain) and provides a macronutrient breakdown (protein, carbs, fat) to help you plan your nutrition effectively.

Can I use this calculator for weight loss?

Yes, select 'Weight Loss' as your goal, and the calculator will recommend a calorie deficit (typically 500 calories below your TDEE) to help you lose approximately 0.5-1 kg per week.

What macronutrient ratio does the calculator use?

For weight loss: 40% carbs, 30% protein, 30% fat. For maintenance: 50% carbs, 25% protein, 25% fat. For muscle gain: 55% carbs, 25% protein, 20% fat. These are general guidelines that can be adjusted based on individual preferences.
