Based on your measurements:  
- Weight: {weight} kg  
- Height: {height} cm  
- BMI: {bmi_rounded} ({bmi_category})  

Your estimated daily calorie needs are approximately {daily_calories} calories.  

RECOMMENDED DAILY NUTRITION:  
• Protein: {daily_protein}g ({round(daily_protein_calories)} calories)  
• Carbohydrates: {daily_carb}g ({round(daily_carb_calories)} calories)  
• Fats: {daily_fat}g ({round(daily_fat_calories)} calories)  

MEAL PLAN FOCUS:  
Your diet should focus on {diet_focus}.
