What the prompt labels mean

Before you start, ask me 1–3 short questions about the details below and wait for my answers. Once I've answered, confirm the plan in one line and run the whole task start to finish.

Goal: Adjust today's meals so I stay close to my daily calorie and protein targets for type 2 diabetes.

Questions to ask me first:
- What happened today that changed the plan (skipped meal, a treat, a late dinner)?
- What are my calorie and protein targets, and any foods I avoid?
- Is my plan agreed with my doctor or dietitian?

Inputs (fill in or confirm):
- Daily target: [CALORIES] calories, [PROTEIN] g protein
- What I've eaten so far today: [FOOD SO FAR]
- Meals left today: [MEALS LEFT]
- Foods I like or avoid: [PREFERENCES]

Rules:
- Give calorie estimates as ranges, and say when a homemade, restaurant or festival dish is hard to estimate.
- Suggest simple swaps using everyday foods I already eat.
- Never suggest changing, skipping or timing my medicines; tell me to ask my doctor about anything medical.
- If I mention very high or low blood sugar or feeling unwell, tell me to contact my doctor or get urgent help instead of adjusting food.

Checkpoint: Show me your estimate of what I've eaten so far and wait for me to correct it before changing the rest of the day.

If you get stuck: If you can't estimate a food, ask me for the portion size or ingredients rather than guessing.

Verify before you finish: Check the adjusted day still lands within my calorie range and protein goal.

Output: A short revised plan for the rest of today, with a calorie range for each meal and one tip.

Done when: I have a realistic plan for the rest of the day that I can check with my care team.

Outcome

Ankush Joshi has lived with type 2 diabetes since 2012 and used ChatGPT to build a 1,200-calorie, high-protein, high-fiber plan of four meals a day. When a day goes off plan, Joshi asks for quick changes, such as moving calories toward dinner or adding 20 g of protein without adding calories. After 2 laddoos and a small chakli at a festival, ChatGPT estimated the extra calories and suggested lighter swaps and a 45-minute walk. Joshi says it is less accurate for homemade, restaurant and festival food, and the rule stays: 'NEVER change medicines based on AI.'
