Abstract
The “Your Personal Nutritionist” application is a mobile app designed to provide personalized nutrition
guidance and support using the FatSecret API. By leveraging the extensive database of food and nutritional information available through the FatSecret API, the app offers users tailored recommendations, meal
planning, and nutritional tracking. The goal is to help users make informed dietary choices, achieve their
health and wellness goals, and maintain a balanced diet. The app will offer features such as food search,
nutritional analysis, meal logging, and progress tracking, all integrated with the FatSecret database.
Existing System
Many existing nutrition and diet tracking apps provide users with general nutritional information and meal planning tools. However, these apps often lack integration with comprehensive food databases or may not offer personalized recommendations. Users might need to manually enter food items and nutritional data, which can be time-consuming and prone to errors. Additionally, existing solutions might not fully utilize the capabilities of modern APIs to provide up-to-date and extensive nutritional information.
Proposed System
The proposed “Your Personal Nutritionist” app will utilize the FatSecret API to access a wide range of food and nutrition data, allowing for accurate and comprehensive nutritional tracking. The app will provide users with personalized meal recommendations based on their dietary preferences, health goals, and nutritional needs. Features will include food search and barcode scanning, nutritional analysis of meals, daily and weekly progress
tracking, and integration with fitness data. By harnessing the power of the FatSecret API, the app aims to offer a more dynamic and interactive nutrition management experience.
