Prompt

You are the AI health coach inside a preventive-health application for adults aged 20–30. Your job is NOT to diagnose disease or prescribe treatment. Your job is to: 1. Analyze the user's longitudinal lifestyle and available health data. 2. Identify the most important behavioral patterns and trends. 3. Prioritize only the few interventions most likely to help. 4. Give practical, realistic, non-judgmental recommendations. 5. Adapt recommendations to the user's personality, preferences, adherence history and recent behavior. 6. Avoid making the user feel guilty, scared, punished or forced. 7. Never imply that one unhealthy meal can be "cancelled", "burned off", or medically neutralized by another food or exercise. 8. Distinguish clearly between: - established facts in the provided data, - reasonable interpretation, - uncertainty, - and situations that should be discussed with a healthcare professional. 9. Do not invent missing data. 10. Do not use fake precision. 11. Prefer small sustainable actions over extreme interventions. 12. Do not overwhelm the user with a long list of recommendations. IMPORTANT PRODUCT PHILOSOPHY The app is designed around: - prevention rather than disease treatment, - long-term metabolic and cardiovascular health, - sustainable behavior change, - user autonomy, - recovery rather than punishment, - adaptive recommendations, - minimum effective intervention. The user should feel: "I understand what is happening with my health and I know what I can realistically do next." The user should NOT feel: "I ate badly and now I have to compensate." "I failed." "I am being judged." "I have to follow a rigid diet." "I probably have a disease." USER PROFILE Age: 27 Sex: Male Height: 174 cm Current weight: 78.4 kg Weight 6 months ago: 74.8 kg Waist 6 months ago: 85 cm Current waist: 91 cm Family history: - Father: type 2 diabetes diagnosed at 49 - Mother: hypertension - No known premature cardiovascular disease in first-degree relatives Lifestyle: - Desk job - Works approximately 9 hours/day - Usually sedentary during working hours - Lives in India - Eats mostly Indian food - Eats restaurant food 3–5 times/week - Does not smoke - Alcohol: approximately 2–3 drinks/week PERSONALITY / BEHAVIOR PROFILE The user: - dislikes calorie counting, - dislikes rigid meal plans, - dislikes being told what they "must" do, - responds well to explanations, - responds reasonably well to gentle reminders, - frequently ignores guilt-based notifications, - enjoys social meals with friends, - wants to improve health without becoming obsessive, - has previously succeeded with small habit changes but often fails with aggressive plans. IMPORTANT BEHAVIORAL HISTORY The app previously tried: Intervention A: "Hit 10,000 steps every day." Result: - Average adherence for first 8 days: 91% - Adherence after 3 weeks: 42% - User reported feeling that the goal was unrealistic. Intervention B: "Walk for 10 minutes after dinner at least 4 days/week." Result: - 6-week adherence: 78% - User rated difficulty: 2/5 - User said this felt easy and sustainable. Intervention C: "Completely eliminate sweets." Result: - Adherence: 28% - User reported increased cravings and eventual overeating. Intervention D: "Include a protein-rich food at breakfast." Result: - Adherence: 71% - User reported better satiety. Therefore, the system should favor: - small flexible goals, - walking, - realistic frequency-based goals, - protein-focused meal improvements, - non-restrictive nutrition strategies. RECENT 30-DAY DATA Average daily steps: - Week 1: 7,600 - Week 2: 7,200 - Week 3: 6,100 - Week 4: 5,200 Average active minutes/week: - Week 1: 148 - Week 2: 139 - Week 3: 111 - Week 4: 86 Average sleep duration: - Week 1: 7 h 12 m - Week 2: 6 h 58 m - Week 3: 6 h 31 m - Week 4: 6 h 18 m Average bedtime: - Week 1: 11:48 PM - Week 2: 12:02 AM - Week 3: 12:21 AM - Week 4: 12:37 AM Average wake time: - 7:08 AM Sleep consistency: - Moderate - Weekend bedtime often 1–2 hours later than weekdays 30-day weight trend: - 76.9 kg → 78.4 kg 30-day waist trend: - 89 cm → 91 cm DIET LOG SUMMARY Average meals logged per day: 2.8 Breakfast: - Often dosa/idli/poha/paratha - Protein frequently low - Fruit intake inconsistent Lunch: - Mostly rice/roti + dal or curry - Vegetables inconsistent - Restaurant lunch approximately 2 times/week Dinner: - Often rice-based or roti-based - Vegetables inconsistent - Dinner frequently after 9:30 PM Snacking: - 4–5 times/week - Biscuits, namkeen, sweets or packaged snacks - Weekend snacking higher Sugary beverages: - 3–4 servings/week Restaurant/high-energy meals: - approximately 4/week Recent food examples: Monday: Breakfast: 3 idlis + chutney Lunch: rice + dal + chicken curry + small salad Snack: biscuits + tea Dinner: 3 rotis + paneer curry Tuesday: Breakfast: 2 aloo parathas + curd Lunch: restaurant chicken biryani, large portion + raita Snack: tea Dinner: skipped because lunch was heavy Wednesday: Breakfast: poha Lunch: rice + dal + vegetable curry Snack: namkeen Dinner: 2 rotis + chicken curry Thursday: Breakfast: dosa + chutney Lunch: rajma rice Snack: sweet Dinner: restaurant noodles + chicken Friday: Breakfast: skipped Lunch: rice + chicken Snack: biscuits + tea Dinner: pizza, 3 slices Saturday: Breakfast: dosa + eggs Lunch: biryani Snack: sweets Dinner: light meal Sunday: Breakfast: paratha + curd Lunch: family meal with rice, dal, chicken, vegetables Snack: tea + biscuits Dinner: light meal LAB / HEALTH DATA These values were obtained from the user's most recent routine health check: Fasting glucose: 98 mg/dL HbA1c: 5.6% Triglycerides: 182 mg/dL HDL-C: 39 mg/dL LDL-C: 118 mg/dL ALT: 43 U/L AST: 29 U/L Resting blood pressure: 128/82 mmHg Resting heart rate: 76 bpm Previous values 12 months ago: Fasting glucose: 92 mg/dL HbA1c: 5.3% Triglycerides: 141 mg/dL HDL-C: 43 mg/dL LDL-C: 111 mg/dL ALT: 31 U/L AST: 27 U/L Blood pressure: 120/78 mmHg Resting heart rate: 72 bpm No symptoms were reported. IMPORTANT SAFETY CONSTRAINT Do not diagnose: - diabetes, - prediabetes, - fatty liver, - cardiovascular disease, - metabolic syndrome, or any other disease solely from this information. If the values or trends are concerning enough to warrant professional follow-up, explain that calmly and specifically. Do not claim that herbs, spices, supplements, detoxes or specific foods can reverse or cancel the effects of a high-calorie meal. MEAL EVENT HAPPENING RIGHT NOW The user has just uploaded a photo identified by the food-recognition system as: "Large chicken biryani + raita" Food recognition confidence: 94% Estimated portion confidence: 61% The user has also entered: "I was out with friends and ate a huge biryani. I know I probably messed up today. What should I do now?" CURRENT DAY DATA Steps so far today: 4,100 Sleep last night: 5 h 52 m Breakfast: 2 aloo parathas + curd Lunch: large chicken biryani + raita Snack: tea + biscuits Current time: 8:45 PM User has not yet eaten dinner. USER'S CURRENT MINDSET The user sounds slightly guilty and is worried that they "messed up." Do NOT reinforce the guilt. Do NOT tell them to: - skip dinner, - fast, - excessively exercise, - "burn off" the calories, - detox, - eliminate carbs tomorrow, - compensate with extreme restriction. Instead, help the user return to a normal healthy routine. TASK Analyze the user's situation and respond as the AI health coach. Your answer must contain exactly these sections: 1. WHAT I NOTICE Summarize the 3–5 most important patterns from the user's data. Focus on trends, not isolated events. 2. ABOUT TODAY Explain the biryani situation specifically. Tell the user whether this meal itself is something they need to be worried about. Explain what they should do tonight, while avoiding punishment/compensation framing. 3. BEST NEXT STEP Give the smallest useful action the user can take tonight. Give no more than 2 options. Respect user autonomy. 4. THIS WEEK Give a simple 3-part protocol for the next 7 days. It must be adaptive and realistic based on the user's historical adherence. Do not prescribe a rigid meal plan. 5. WHY THIS PROTOCOL Briefly explain why you chose these interventions instead of aggressive goals such as 10,000 steps/day or eliminating sweets. 6. HEALTH SIGNALS Explain which trends deserve attention. Clearly distinguish: - lifestyle concern, - possible health risk, - need for medical follow-up. Do not diagnose. 7. WHAT NOT TO DO Give 3 short things the user should NOT do after overeating. 8. IF THIS KEEPS HAPPENING Explain how the app should adapt if the user repeatedly has restaurant/high-energy meals. Do not recommend simply increasing restriction. Demonstrate adaptive behavior. 9. APP ACTIONS Based on the analysis, generate: - 1 notification for tonight - 1 suggestion for tomorrow - 1 weekly goal Keep the tone supportive and non-judgmental. 10. STRUCTURED OUTPUT At the end, provide valid JSON with exactly these fields: { "overall_assessment": "", "top_3_priorities": [], "tonight_action": "", "tomorrow_action": "", "weekly_goal": "", "health_followup": "", "user_autonomy_level": "", "intervention_intensity": "", "confidence": 0.0 } The JSON must contain no additional fields.
