AI Diet Plan Generator Platform Development Case Study
Project Description
Nutrify is an AI-powered Diet Plan Generator Platform developed for a nutrition business with a database of over 10,000 recipes. The platform enables fitness trainers, nutritionists, and individuals to generate personalized 7-day diet plans based on their unique health profile, nutritional goals, food preferences, and lifestyle.
Users can provide information such as gender, age, height, weight, activity level, fitness goal, preferred diet, foods to avoid, country, and additional health notes. Using this information, the platform creates a balanced meal plan while calculating appropriate portions and daily nutritional intake. Users can also choose from different AI nutrition specialists—including Sports Nutritionist, Vegan Nutritionist, Vegetarian Nutritionist, Youth Nutritionist, and Holistic Nutritionist—to receive recommendations tailored to their specific dietary philosophy.
The platform also includes an AI nutrition assistant that answers only nutrition-related questions, allowing users to discuss, modify, and personalize their meal plans before exporting them as a PDF.

Business Challenge & Our Solution
We helped transform a nutrition platform by building an intelligent AI-powered diet planning system that delivers truly personalized results.
Business Challenge
The client owned a nutrition platform containing more than 10,000 professionally curated recipes. The goal was to generate personalized 7-day diet plans that accurately matched each user's nutritional targets instead of producing generic AI-generated meal suggestions.
The primary challenge was that the complete recipe database could not be sent directly to the language model because of token limitations. In addition, every generated diet plan had to satisfy user-specific calorie, protein, carbohydrate, and fat targets while considering meal preferences, food restrictions, country-specific eating habits, and fitness goals.
The platform also needed to recommend practical serving sizes such as bowls, spoons, glasses, and portions rather than simply listing recipes.
Our Solution
We developed Nutrify, a custom AI Diet Plan Generator Platform powered by ChatGPT and a proprietary recipe selection engine.
Instead of sending the complete recipe database to the AI model, we designed a structured retrieval process by categorizing recipes into breakfast, lunch, dinner, snacks, beverages, and additional food groups. Every recipe was enriched with detailed nutritional information, including calories, protein, carbohydrates, fats, and serving units.
Our recommendation algorithm first filtered recipes based on the user's dietary preferences, nutritional goals, and meal categories. It then calculated the required quantity for each recipe to meet daily nutrition targets before sending only the most relevant recipe data to the AI model in optimized context chunks.
This hybrid architecture significantly reduced token usage while enabling the AI assistant to generate accurate, personalized, and nutritionally balanced meal plans.
