General meal-planning tips, not a clinical nutrition plan
Free.ai is not a Registered Dietitian (RD / RDN). Macros and calorie targets are estimates from general formulas. For diabetes, kidney disease, eating disorders, pregnancy, or any medical condition, consult a registered dietitian or your physician before starting a new diet.
Your Diet Plan
Estimates only — calorie + macro targets are general estimates. For medical conditions or weight loss greater than 1-2 lbs/week, consult a Registered Dietitian.

Describe your situation, pick a diet style chip (Balanced, Mediterranean, Vegetarian, Vegan, Keto, Paleo, DASH, Gluten-free, High-protein, Intermittent Fasting), set goal (loss / maintenance / gain / muscle / health / performance), pick duration (1/3/7/14 days), set activity level, check allergens to avoid, and the AI generates a structured plan — daily targets (calories + macros), meal-by-meal plan, aggregated grocery list, prep tips, and red flags for when to see a Registered Dietitian.
Yes. Each plan costs ~500 tokens from your daily pool (2,500 guest, 10,000 signed-up). No watermark, no subscription, no signup required. Noom charges $70/month, PlateJoy $12.99/month, Eat This Much $8.99/month.
No — Free.ai is not a Registered Dietitian (RD / RDN). Macros and calorie estimates use general formulas (Mifflin-St Jeor for BMR, activity multipliers for TDEE). For diabetes, kidney disease, eating disorders, pregnancy, or any medical condition, see a registered dietitian or your physician — clinical nutrition therapy is a regulated profession for good reason.
The AI uses your activity level + stated goal to estimate daily calories. Weight loss assumes a 500 kcal/day deficit (1 lb/week loss). Muscle building assumes a 250-500 kcal/day surplus. Maintenance matches estimated TDEE. Always treat as a starting point — log actual weight and adjust by ±10% after 2-3 weeks if you are not trending toward your goal.
Yes — check all that apply (gluten, dairy, tree nuts, peanuts, eggs, soy, shellfish, pork, red meat). The AI avoids those ingredients entirely throughout the plan and suggests safe substitutes. For severe allergies (anaphylaxis), always cross-check ingredient lists at the grocery store — AI cannot guarantee no cross-contamination in processed foods.
Noom ($70/mo) layers behavioral psychology + food logging + coaching. PlateJoy ($12.99/mo) generates personalized meal plans with grocery export. Eat This Much ($8.99/mo) does daily meal generation with macro targets. Free.ai gives you the structured plan instantly — best paired with one of those for ongoing tracking + community support.
Yes — pick the Intermittent Fasting 16:8 style and the AI plans meals within an 8-hour eating window (default noon-8pm; adjust to your schedule). All daily macros and calories fit inside that window. For longer fasts (OMAD, alternate-day, prolonged), discuss with a physician first — extended fasting affects medications and is contraindicated for some conditions.
Yes — pick Vegan + High-Protein and the AI emphasizes legumes, tofu, tempeh, seitan, edamame, lentils, quinoa, hemp seeds, nutritional yeast. Hitting 1.6-2.2 g/kg protein on a vegan diet is achievable with planning. Supplement B12 always; consider iron + zinc + omega-3 (algae-based EPA/DHA) per a registered dietitian recommendation.
AI-generated plans are NOT for diabetes management. Carb counting, glycemic load, insulin dosing, and medication interactions require a Certified Diabetes Care and Education Specialist (CDCES) or your endocrinologist. Free.ai is a starting framework only — never substitute for clinical care for type 1, type 2, or gestational diabetes.
Currently it generates a complete list assuming bare cupboards. Cross-reference your pantry before shopping to avoid duplicates. Future versions will accept a "pantry inventory" input — for now, list ingredients you already own in the description field and the AI will use them where possible.
Copy the meal plan + grocery list to any tracker. MyFitnessPal accepts manual entry or recipe URL imports. For exact gram-level macros, use MyFitnessPal's database after the fact — Free.ai gives nutrition estimates per typical preparation, which can vary 10-20% by brand and portion.
Yes — POST to /v1/chat/ with the diet-plan system prompt, billed at ~500 tokens per plan. Useful for nutrition-app integrations and corporate wellness programs. Bearer auth via /developer/, full snippets at /api/.
