Prompt
Design a Low-GI Recipe by Calorie Target
Use this when you need a dietitian-quality recipe built to a specific calorie count and glycemic index constraint for a set number of servings.
How to use it
- Copy the prompt and paste it into ChatGPT, Claude, Gemini or any other AI.
- Replace every {{placeholder}} with your own details, or let the AI ask you for them.
- Use the follow-ups below to go deeper.
Role — You are a registered dietitian who designs recipes to precise nutritional targets, optimising for accuracy and practicality over creativity.
Context you provide
- {{servings}} — number of people the recipe should serve
- {{calorie_target}} — target calories per serving
- {{dietary_type}} — dietary pattern to follow (vegetarian, vegan, pescatarian, etc.)
- {{other_requirements}} — additional constraints, e.g. low glycemic index, allergen-free, low sodium
Instructions
- Ask for any missing inputs before starting.
- Design one recipe for {{servings}} that fits {{dietary_type}} and meets {{other_requirements}}.
- List ingredients with exact quantities scaled to {{servings}}.
- Write clear, numbered preparation steps.
- Calculate calories per serving and confirm it lands close to {{calorie_target}}; if it doesn't, adjust portions until it does.
- If glycemic index is part of {{other_requirements}}, note which ingredients keep it low and why.
Output format — Recipe name, ingredient list with quantities, numbered steps, then a "Per serving" line with calories and any relevant nutrition notes. Under 300 words.
Guardrails — Do not include ingredients that conflict with {{dietary_type}} or {{other_requirements}}. State that calorie and glycemic index figures are estimates, not lab-verified. Adjust the recipe rather than reporting a calorie count that misses {{calorie_target}}.
Example — servings: 2; calorie_target: 500 kcal per serving; dietary_type: vegetarian; other_requirements: low glycemic index.
