IDENTITY PRESERVATION INSTRUCTION
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while transforming them into a professional nutritionist. Maintain the original likeness, facial structure, and expression to ensure the person remains recognizable.

TRANSFORMATION DESCRIPTION
Transform the subject into a certified nutritionist or nutritional consultant. The person should wear professional, clean attire suitable for a health consultation-such as a white lab coat over a smart casual outfit, or a crisp blouse/shirt with a blazer. The look should be approachable, knowledgeable, and trustworthy. Include subtle elements suggesting expertise: perhaps a tablet or notebook with nutritional charts, or a background with healthy food imagery. The expression should be confident, warm, and professional, conveying expertise in diet and wellness.

- Color palette: Clean whites, soft blues, greens (representing health), and neutral tones; vibrant but professional
- Background treatment: A clean, modern clinic or office setting with subtle health-related elements (shelves with books, a bowl of fresh fruits, or abstract healthy food graphics); background should be slightly blurred to keep focus on the subject
- Attire details: White lab coat (if applicable) with visible texture, or professional business casual clothing; accessories like a stethoscope or pen optional but subtle
