Millions of people aim to lose weight or simply improve their diet. But most face the same challenges: calorie counting is hard, product knowledge is limited, motivation fades quickly, and standard diets don’t consider personal preferences.

FitGuide Bot solves these problems: instead of dry tables and complicated apps — it’s a live conversation in Telegram where everything is clear and accessible.

• difficult to calculate the right amount of calories;
• lack of knowledge about which products to choose;
• no discipline or motivation;
• standard diets don’t fit personal preferences and get boring fast;
• as a result, most give up without achieving results.

We developed FitGuide Bot, which step by step helps users improve their diet and lose weight.

• Calorie and macro calculation based on age, weight, height, and activity.
• Personal meal plans (sugar-free, meat/seafood focused, vegetarian, etc.).
• Weekly menu with recipes and step-by-step instructions.
• Reminders for meals, water, and workouts.
• Progress tracking: weight, measurements, and stats.
• Motivation: tips, supportive messages, mini challenges.

• Backend: .NET Core (C#), ASP.NET Web API, MySQL database.
• Frontend: Telegram Bot API with inline buttons.
• AI module: GPT for motivation and recipe adaptation.
• Redis for caching and queues.
• Integrations: USDA FoodData API, Firebase (future use).
• Infrastructure: Docker + Kubernetes, AWS.
• Security: JWT tokens and personal data protection.

• Marina, 32: 1500 kcal sugar-free menu → lost 7 kg in 2 months.
• Igor, 40: 1700 kcal plan with focus on meat and vegetables → lost 5 kg in a month.
• Anna, 25: vegetarian, received a balanced menu without meat or fish.

• helps build healthy habits;
• makes weight loss simple and clear;
• saves time on calculations and recipe searches;
• provides daily motivation and support.

This is an example of how AI can transform daily habits and bring real value to people.
