In recent years, major advances in artificial intelligence (AI) have led to the development of powerful AI systems for use in the field of nutrition in order to enhance personalized dietary recommendations and improve overall health and well-being. However, the lack of guidelines from nutritional experts has raised questions on the accuracy and trustworthiness of the nutritional advice provided by such AI systems. This paper aims to address this issue by introducing a novel AI-based nutrition recommendation method that leverages the speed and explainability of a deep generative network and the use of novel sophisticated loss functions to align the network with established nutritional guidelines. The use of a variational autoencoder to robustly model the anthropometric measurements and medical condition of users in a descriptive latent space, as well as the use of an optimizer to adjust meal quantities based on users' energy requirements enable the proposed method to generate highly accurate, nutritious and personalized weekly meal plans. Coupled with the ability of ChatGPT to provide an unparalleled pool of meals from various cuisines, the proposed method can achieve increased meal variety, accuracy and generalization capabilities. Extensive experiments on 3000 virtual user profiles and 84000 daily meal plans, as well as 1000 real profiles and 7000 daily meal plans, demonstrate the exceptional accuracy of the proposed diet recommendation method in generating weekly meal plans that are appropriate for the users in terms of energy intake and nutritional requirements, as well as the easiness with which it can be integrated into future diet recommendation systems.
近年来,人工智能(AI)领域取得了重大进展,开发出了强大的 AI 系统,用于营养领域,以增强个性化饮食建议,提高整体健康和幸福感。然而,营养专家缺乏指导方针,这使得人们对这些 AI 系统提供的营养建议的准确性和可信度产生了疑问。本文旨在通过引入一种新的基于 AI 的营养推荐方法来解决这个问题,该方法利用深度生成网络的速度和可解释性,以及使用新颖的复杂损失函数使网络与既定的营养指南保持一致。使用变分自动编码器在描述性潜在空间中稳健地建模用户的人体测量和医疗状况,以及使用优化器根据用户的能量需求调整膳食量,使该方法能够生成高度准确、营养丰富且个性化的每周膳食计划。加上 ChatGPT 提供各种菜肴无与伦比的海量食物的能力,该方法可以实现更高的膳食多样性、准确性和泛化能力。在 3000 个虚拟用户档案和 84000 个日常膳食计划以及 1000 个真实档案和 7000 个日常膳食计划上进行了广泛的实验,结果表明,该建议的膳食推荐方法在生成适合用户能量摄入和营养需求的每周膳食计划方面具有出色的准确性,并且易于集成到未来的膳食推荐系统中。
