OUR APPROACH

Why Nutryon and not a generic AI.

Anyone can generate a diet with AI. Nutryon doesn’t improvise — and above all, it doesn’t forget you the month after.

Generic AI

Chatbot
  • Gives you a generic response — doesn’t know who you are
  • Calculates nothing — improvises on text
  • Calories? An approximation, not a formula
  • Leaves you a text to interpret on your own
  • Generates a diet and disappears — doesn’t know what happened the month after
  • Tomorrow it won’t remember you
Nutryon

Nutryon System

Nutryon
  • Knows your body, your lifestyle, your goals
  • Calories calculated with the Mifflin-St Jeor formula — the international scientific standard
  • Macros personalised on weight, goal and real activity level
  • Delivers a plan ready to follow, not to interpret
  • After 25 days it analyses your results and explains what changes in the new plan
  • Every month it updates with you — real weight, real adherence, real results

Nutryon doesn’t improvise. It calculates. It observes. It improves.

FAQ

Frequently Asked Questions

Everything you need to know about Nutryon

Nutryon is an Italian AI-powered nutrition platform that generates personalised monthly nutrition plans in PDF. It calculates calories, macronutrients and meal structure based on user data, following scientific formulas and CREA and WHO dietary guidelines.
Nutryon uses the Mifflin-St Jeor formula to calculate your basal metabolic rate (BMR), adjusted for physical activity level, daily steps and sleep quality. Your total daily energy expenditure (TDEE) is then tailored to your goal: a deficit for fat loss, a surplus for muscle gain, or maintenance for body recomposition.
Yes. Every plan generated by Nutryon is aligned with the official dietary guidelines of the user's country, WHO principles for healthy eating and the UNESCO-recognized Mediterranean dietary model. Seasonal food selection is adapted based on the country specified in your profile.
ChatGPT generates plausible but unverified text. Nutryon uses a deterministic engine that calculates calories and macronutrients using validated scientific formulas, enforces safety floors (minimum 1,100 kcal for women, 1,400 kcal for men), and produces a structured professional PDF. It is not a chatbot — it is a controlled nutrition generation system.
Yes. Nutryon supports four main goals: fat loss, muscle gain, body recomposition, and athletic performance improvement. For each goal, the system calculates specific caloric deficits or surpluses and adjusts macronutrients accordingly.
You can generate a new plan whenever your conditions change — weight change, new goal, new food preferences. Each plan is independent and recalculated from scratch based on your updated profile.
Yes. During profile setup, users can specify intolerances, allergies, foods to avoid, preferences, and dietary patterns (omnivore, vegetarian, vegan). The generated plan respects all declared preferences.
Yes. The platform is available in both Italian and English. Nutrition plans are generated in the user's country language, with localised seasonal and regulatory references.
