1. The Features of Nutrition Applications That ChatGPT Can or Cannot Emulate

People have long relied on nutrition applications to track their daily food intake, monitor macronutrient ratios, and access valuable information for nutrition education. These applications have played a significant role in helping people manage their dietary habits and make informed choices about their nutrition. With the advent of ChatGPT, there is now an opportunity to explore how this advanced language model can further enhance nutrition knowledge and contribute to the field. To initiate the discourse regarding its potential in improving nutrition knowledge, this preseaperrch explores common features of nutrition applications as references. Examining these features may serve as a basis for identifying areas where ChatGPT can contribute to the field of nutrition.

1.1. Verified Nutrition Database

Nutrition applications heavily rely on comprehensive databases that contain accurate information regarding the nutritional composition of different foods and ingredients. One illustrative example is the ‘Plan-Cook-Eat’ application that utilized a combination of the Philippine Food Composition Table, My Food Data, FooDb, and USDA Food Composition Databases [47][1]. These nutrition databases serve as a crucial resource for analyzing dietary intake, providing personalized recommendations, and facilitating nutritional tracking. Consequently, users can search for specific foods and learn about their macro- and micronutrient compositions (e.g., What is the nutritional value of 100 g of broccoli?). Unfortunately, it is plausible that ChatGPT lacks a dedicated and verified nutrition database of its own and instead relies on various publicly available databases for nutritional information retrieval. This reliance on external sources may introduce limitations in terms of ensuring the accuracy and reliability of the nutritional data provided by the system.

1.2. Personalized Meal Planner

Meal planning is an important process for ensuring a healthy and well-balanced diet. More importantly, customizing meals to accommodate individual preferences, dietary restrictions, and daily caloric requirements is crucial for improving adherence to a particular meal plan [33][2]. When ChatGPT is presented with this array of variables (as exemplified in the sample prompt below), it is more likely to generate personalized meal plans that cater to individual needs. Like other knowledge-based systems, ChatGPT can function as a robust recommender system with its advanced algorithms and language processing capabilities. This important feature helps users diversify their diet, discover new healthy recipes, and optimize their nutrient intake. It also promotes a better understanding of how to create well-rounded meals while accommodating dietary considerations. Nonetheless, it is noteworthy that ChatGPT does not have the capability to manage calendars or schedule tasks, which are important characteristics of a meal planner application.
Sample prompt:
“I am looking for a personalized meal plan that can help me manage my weight while following a vegetarian diet. To maintain my weight, I need to eat 2500 calories per day. I usually eat three times a day. I prefer Filipino cuisine, but I have a peanut allergy. Suggest a meal plan that consists of breakfast, lunch, and dinner.”

1.3. Food Intake Tracker

Monitoring food consumption also plays a vital role in sustaining a healthy lifestyle. Many nutrition applications, e.g., [48][3] incorporate this crucial feature to simplify daily intake tracking. This feature helps users understand their dietary patterns, identify potential nutrient imbalances, and make informed, health-conscious decisions regarding their food choices. Conversely, albeit capable of retaining and leveraging past conversations, the interface of ChatGPT does not adhere to the structure and functionality of a conventional food diary. For instance, it does not offer a calendar feature, making it less intuitive to navigate and review past food intake records. Unlike the user interface of Virtual Dietitian presented in Figure 1, ChatGPT lacks the functionality to easily confirm whether the suggested food from the meal plan has been consumed. This limitation in the ChatGPT interface can make it difficult for users to effectively monitor their food consumption.
Figure 1.
Food Diary Interface in the Virtual Dietitian Application.

1.4. Dietary Advice and Guidance

The capability of a nutrition tool to offer dietary advice and guidance is paramount in empowering individuals to engage in interactive discussions about their nutrition-related inquiries. Unfortunately, most existing nutrition applications lack this functionality due to their limited capacity to comprehend human language. ChatGPT demonstrates superiority in this regard owing to its conversational nature. Users can pose inquiries related to various food groups as well as the significance of specific nutrients or seek clarification regarding prevalent dietary misconceptions. This feature promotes nutrition education as it empowers users to engage in meaningful and informative discussions. Nevertheless, it is imperative to acknowledge persisting concerns regarding the accuracy of the advice offered, despite prior reports indicating positive outcomes. Ensuring the precision, reliability, and accuracy of health guidance remains a critical issue in AI-driven applications.
Sample prompt:
“Can you explain the difference between saturated fats and unsaturated fats and provide recommendations on which types of fats are healthier to consume?”

1.5. Community and Support

Many nutrition applications attempt to cultivate a sense of community by providing forums, groups, and other social features where users can interact, share experiences, and seek advice. Despite its ability to communicate with users, it is important to acknowledge that ChatGPT may not fully replicate the immersive nature of such real-world communities. These communities inherently possess unique social dynamics and the ability to bring together individuals with diverse perspectives and experiences. Interacting with others in these communities allows for the exchange of firsthand knowledge, personal anecdotes, and collective wisdom. This feature can be invaluable in navigating the complexities of nutrition by providing an opportunity to learn from others. As pointed out by Michalski et al. [49][4], having weaker community belonging is detrimental because it is associated with poorer general and mental health across various life stages (18 and above years old).

1.6. Assessment Tools and Calculators

Assessment tools and calculators are also essential features of nutrition applications because they provide users with personalized insights, guidance, and a quantifiable understanding of their dietary habits. These tools can evaluate nutrient intake, identify deficiencies or excesses, and suggest appropriate adjustments. Additionally, they assist users in determining their daily calorie requirements, macronutrient distribution, and body mass index. ChatGPT possesses the capability to emulate these functions by replicating the underlying algorithms and formulas used in assessment tools and calculators. For example, ChatGPT can calculate the Total Daily Energy Expenditure by considering parameters such as height, weight, age, gender, and activity level, as shown in the given prompt:
Sample prompt:
“I am interested in knowing the number of calories I burn in a day. Here are my details: I am 31 years old, male, with a height of 177 cm and a weight of 92 kg. Additionally, I would describe my activity level as very active. While you are at it, how much food should I eat in day to safely lose weight?”

1.7. Tips and Reminders

Nutrition applications commonly include a feature that sends daily tips and reminders to their users, aiming to inform and motivate them to adopt healthier choices and improve their nutrition [50][5]. These automated messages serve as gentle prompts and constant sources of inspiration to support individuals in their pursuit of better eating habits. These daily tips and reminders are invaluable in several ways. Firstly, they act as timely prompts that keep nutrition at the forefront of users’ minds. This consistent reinforcement encourages users to make conscious choices throughout the day, gradually steering them toward more nutritious options. Secondly, these messages often contain practical advice, actionable recommendations, and insights into healthier eating practices. They empower users with the knowledge needed to make informed dietary decisions. However, it is important to acknowledge that ChatGPT operates differently from a conventional nutrition tool. Unlike applications that can send direct notifications and reminders, ChatGPT functions as a conversational AI tool. Nonetheless, users can leverage its capabilities to obtain strategies and supplementary information about maintaining a healthy lifestyle.
Sample prompt:
“Can you suggest healthy options for satisfying sweet cravings?”

1.8. Nutrition Education Materials

Interactive lessons and modules that provide users with in-depth information about various aspects of nutrition are another prevalent feature. Nutrition tools often have the technical infrastructure and innovative features to actively engage their users. They go beyond mere dissemination of information by incorporating interactive elements that encourage user participation. These might include quizzes, assignments, and self-assessments, all aimed at reinforcing the learning process. As users progress through these modules, they not only gain knowledge but also develop practical skills related to nutrition. On the other hand, ChatGPT offers a distinct approach to learning and information dissemination. While it may not have a direct interface with nutrition education materials, it serves as an accessible learning platform in its own capacity. Users can engage with ChatGPT by posing questions, seeking clarification, and requesting information related to nutrition or any other subject matter. Its strength lies in its ability to provide quick and responsive answers to user queries. For instance, users can ask questions such as “What are some good dietary sources of omega-3 fatty acids?” and receive immediate responses. This interaction fosters a dynamic and individualized learning experience.

2. ChatGPT Assist throughout Each Stage of the Nutrition Care Process

Dietitians and nutrition professionals frequently employ the Nutrition Care Process (NCP) in providing individualized care to their clients [33][2]. As presented in Figure 2, this systematic methodology encompasses a series of steps, such as (1) nutrition assessment, (2) nutrition diagnosis, (3) nutrition intervention, and (4) nutrition monitoring and evaluation. ChatGPT can play a valuable role in assisting with various aspects of the NCP.
Figure 2.
The Nutrition Care Process and Model.

2.1. Nutrition Assessment

The NCP begins with the collection and interpretation of pertinent information concerning an individual’s current nutritional status, clinical history, physical condition, and other physiological and pathological factors. This initial assessment serves as a foundation for understanding the individual’s specific nutritional requirements and identifying any existing or potential nutrition-related issues. The data obtained during this phase encompasses various elements, such as anthropometric measurements (e.g., height and weight), biochemical data, clinical observations, and dietary intake assessments (commonly referred to as the ABCD method). According to the guidelines provided by the American Society for Parenteral and Enteral Nutrition (ASPEN), a comprehensive nutritional assessment encompasses a thorough clinical examination (i.e., comprising a detailed history and physical examination), anthropometric measurements, diagnostic tests, and dietary assessments [51][6]. Some examples of how ChatGPT can assist in this phase are as follows.
  • Answer questions about specific nutrients, their functions, and dietary sources.
  • Provide general information on dietary guidelines and recommendations.
  • Assess individual nutrition needs based on factors such as age, sex, and activity level.
  • Offer dietary assessment tools and calculators to estimate nutrient intake.
  • Provide guidance on assessing body composition and interpreting results.
  • Explain common nutrition-related health conditions or risk factors.

2.2. Nutrition Diagnosis

Following the assessment, dietitians and nutrition professionals proceed to identify and describe specific nutritional problems or issues. They formulate a clear and concise diagnosis, which serves as the foundation for developing an appropriate intervention plan for the subsequent phase. These diagnoses are formulated using standardized terminology (e.g., International Dietetics and Nutrition Terminology) or other widely recognized classification systems. The comprehensive nature of these systematic frameworks ensures that dietitians consider various factors when formulating diagnoses and intervention plans. Some examples of how ChatGPT can assist in this phase are as follows.
  • Provide sample evidence-based nutrition diagnoses for common health conditions.
  • Assist in identifying nutrition-related problems based on the assessment findings.
  • Explain the significance of nutrition diagnoses in developing intervention plans.
  • Help identify potential comorbidities that may influence the nutrition diagnosis.
  • Offer guidance on documenting nutrition diagnoses in a standardized format.
  • Assist in identifying nutrition-related risk factors for specific populations.

2.3. Nutrition Intervention

After the nutrition diagnoses have been established, dietitians and nutrition professionals proceed to create a comprehensive plan aimed at addressing the identified issues. This plan encompasses specific nutrition interventions, goals, and strategies that are tailored to meet the unique needs of the individual. The interventions employed may involve various approaches, such as dietary modifications, personalized meal planning, nutrition education, and counseling. In some cases, collaboration with other healthcare professionals (e.g., physicians and other specialists) is necessary to ensure comprehensive care. Collaborative practice in nutrition and dietetics plays a pivotal role in promoting the achievement of a healthier and more fiscally responsible healthcare system because it fosters interdisciplinary cooperation, enhances the quality of patient care, and optimizes resource utilization [52][7]. Some examples of how ChatGPT can assist in this phase are as follows.
  • Offer general dietary recommendations for various health conditions or goals.
  • Recommend personalized meal plans based on specific dietary needs or preferences.
  • Provide tips for modifying recipes to improve nutritional content.
  • Suggest behavior change techniques that can support adherence to interventions.
  • Give guidance on portion control and meal frequency for weight management.
  • Suggest resources for finding nutritionally balanced recipes and meal ideas.

2.4. Nutrition Monitoring and Evaluation

In the final step of the NCP, dietitians and nutrition professionals undertake the crucial task of assessing and monitoring the effectiveness of the implemented nutrition intervention over time. This process involves collecting relevant data to evaluate whether the established goals and objectives are being achieved and making necessary adjustments to the intervention plan as required. Regular follow-ups and consistent communication with the individual are pivotal parts of the protocol (Figure 3) for tracking progress, addressing any concerns, and providing ongoing support. This continuous monitoring ensures that the intervention plan remains tailored to the individual’s evolving needs. Nonetheless, in practice, patients and their family members often receive insufficient education regarding proper nutrition care [53][8]. In this phase, ChatGPT can assist in the following ways.
Figure 3.
Sample Nutrition Intervention Protocol generated by the Virtual Dietitian Application.
  • Provide guidance in setting measurable goals related to nutrition interventions.
  • Offer tools for tracking food intake, physical activity, and other lifestyle factors.
  • Assist in analyzing nutrition-related data collected during monitoring.
  • Explain how to interpret changes in laboratory results related to interventions.
  • Assist in identifying potential challenges or barriers to achieving nutrition goals.
  • Offer resources for conducting follow-up assessments and adjusting interventions.

3. Can ChatGPT Effectively Replace Dietitians and Nutrition Professionals?

Numerous recent publications in the field of medical and health sciences have consistently explored whether ChatGPT can serve as a substitute for healthcare professionals. While the debate regarding AI’s role in healthcare continues, the consensus among researchers and experts leans towards the assertion that ChatGPT cannot fully substitute for these skilled professionals, and there are several compelling reasons for this stance. One of the primary reasons lies in the unique expertise, training, and experience that dietitians and nutrition professionals contribute to their practice. For instance, Cheng et al. [54][9] have aptly pointed out that the depth of knowledge possessed by a qualified infectious disease doctor is unparalleled. These professionals have completed rigorous formal education and underwent years of training to specialize in preventing, diagnosing, and treating infectious diseases. Similarly, Frank et al. [55][10] concurred in the field of rheumatology, emphasizing that the critical thinking, expertise, and experience that rheumatologists possess cannot be adequately substituted by ChatGPT. These capabilities, which include clinical training and the ability to exercise clinical judgment, are intricately attached to human expertise. Furthermore, the essence of human interaction and empathy plays a significant role in the healthcare profession, including dietetics and nutrition counseling. Dietitians and nutrition professionals not only provide personalized dietary recommendations but also offer emotional support and motivation to individuals on their wellness journeys. These aspects of care are deeply rooted in the human touch, making their role distinct and irreplaceable [56][11].
From a technical standpoint, the primary reason why ChatGPT cannot fully replace experts is that it is not specifically designed as a nutrition application. As previously discussed, nutrition knowledge-based systems possess certain functionalities that either do not exist or are not fully replicated by ChatGPT. Even these specialized nutrition applications have not been able to entirely supplant the expertise of professionals in the field, and so it is reasonable to deduce that ChatGPT is similarly constrained in its capacity. Instead of viewing ChatGPT as a comprehensive substitute, it should be regarded as a valuable supplementary tool. Expert validation and consultation remain crucial in ensuring accurate and reliable information for optimal care and guidance. As noted by scholars [39][12] in medical education, human oversight remains crucial for ChatGPT to serve as a meaningful learning platform. Sanmarchi et al. [57][13] share a similar opinion that blindly accepting AI-generated answers may pose significant risks to the integrity of scientific endeavors. Therefore, it is crucial to acknowledge that ChatGPT also has its own set of limitations.

3.1. Incorrect Responses

Despite its extensive dataset, ChatGPT is not immune to the generation of incorrect or outdated information. For instance, Niszczota and Rybicka [58][14] investigated the credibility of dietary advice provided by ChatGPT. Their findings uncovered instances where ChatGPT formulated diets that could be potentially unsafe. Other responses inaccurately specified food quantities and energy values. This particular limitation further underscores the importance of cautious interpretation, human validation, and expert judgment [39,59][12][15]. Meanwhile, the dependence of ChatGPT on user-provided information may cause these incorrect responses. This situation can occur when the prompts supplied by users are either inaccurate or incomplete. Therefore, it is advisable to consult experts in the field and exercise personal judgment when making decisions based on the content generated by ChatGPT. This approach helps mitigate the risk of relying on potentially erroneous information and ensures a more accurate and reliable outcome in nutrition and dietary matters.

3.2. Real-Time Monitoring and Feedback

Due to its inherent reliance on text-based communication and web-based platform, a significant limitation of ChatGPT is its inability to perform real-time monitoring and feedback. Unlike other mobile nutrition applications designed for proactive engagement, ChatGPT relies on users to initiate interactions. These dependencies indicate delayed responses, a lack of contextual awareness, and the absence of mechanisms to track user engagement or provide immediate interventions. Consequently, it falls short in delivering immediate and dynamic support comparable to real-time human interactions or dedicated monitoring devices. On the other hand, nutrition applications are strategically designed to offer push notifications as a means of real-time engagement [60][16]. These apps can send timely reminders to users, encouraging them to record their meals, stay hydrated, or engage in physical activity. Other mobile applications use algorithms that analyze user data, such as dietary habits and exercise routines, to create personalized push notifications [61][17]. For example, if a user consistently logs high-calorie meals, the app may send a notification suggesting healthier alternatives. This proactive approach fosters a continuous connection between users and the application as well as provides immediate feedback to help individuals make better dietary choices and maintain their nutritional goals.

3.3. Coordinated Nutrition Services

In complex cases involving multiple concurrent medical conditions, intricate medication regimens, or specialized dietary requirements, ChatGPT may not have the capacity to provide comprehensive and tailored nutrition guidance. These situations often require the involvement of coordinated nutrition services that collaborate with a multidisciplinary team of specialized professionals [62][18]. For instance, a patient with concurrent diabetes, hypertension, and renal disease who is taking multiple medications with varying interactions and has specific dietary restrictions would require comprehensive nutrition guidance which may be beyond the capabilities of ChatGPT. In such cases, coordinated nutrition services would involve a registered dietitian working closely with the patient’s primary care physician, endocrinologist, nephrologist, and potentially other specialists. This collaborative approach ensures that the patient receives tailored and well-coordinated nutrition guidance to effectively manage their health conditions [53][8].

3.4. Hands-On Demonstration

The hands-on approach creates a tangible connection between theory and practice. It allows users to observe, interact, and experience firsthand the practical aspects of nutrition. Unfortunately, ChatGPT cannot physically demonstrate any tasks that require a direct manipulation of objects. For instance, it cannot provide hands-on guidance for meal preparation techniques, portion control, or cooking skills, which are valuable aspects of nutrition education and behavior change [30][19]. As identified by Ali et al. [63][20], hands-on demonstrations are an effective way to teach nutritional concepts. This limitation prevents users from actively engaging their senses, which are crucial for understanding food qualities and developing informed dietary habits. It is also unable to demonstrate how to properly measure anthropometric parameters, such as height, weight, or body composition. These measurements are fundamental in assessing an individual’s nutritional status, determining appropriate dietary interventions, and monitoring progress over time.

3.5. Physical Examination

In the nutrition assessment phase of the NCP, a nutrition-focused physical examination (NFPE) is considered a vital process. As Hummell and Cummings [64][21] astutely noted, in addition to the typical anthropometric measurements and patient’s general appearance, pertinent aspects for a NFPE encompass evaluations of muscle mass, the condition of fingernails, the presence of edema or ascites, handgrip strength, subcutaneous fat reserves, hair quality, skin health, ocular characteristics, oral cavity condition, signs of muscle atrophy, and other relevant parameters. Unfortunately, ChatGPT is unable to perform physical examinations due to the absence of a video camera and video processing features. This inherent constraint prevents ChatGPT from assessing crucial aspects, such as body composition and detecting nutritional deficiencies. Consequently, its ability to provide precise and accurate nutrition recommendations is compromised. Until ChatGPT integrates this feature, traditional NFPEs remain essential for a comprehensive nutrition assessment.

3.6. Verbal and Non-Verbal Cues

During a comprehensive physical checkup, healthcare professionals pay close attention to both verbal and non-verbal signals as they play crucial roles in gathering valuable information. Verbal cues involve the information that clients communicate regarding their dietary habits, food preferences, eating routines, and any nutrition-related symptoms or concerns. On the other hand, non-verbal cues, such as body language, facial expressions, gestures, and tone of voice, offer supplementary insights into the emotional state, comfort level, and attitudes of the client towards food and nutrition. For instance, a client’s verbal commitment to healthy eating may contradict their nervous body language, suggesting hidden influences (e.g., social pressures or emotional concerns) that demand nuanced interpretation. Unfortunately, ChatGPT cannot understand such cues in real-time conversations. This limitation prevents ChatGPT from accurately assessing any underlying factors that may influence an individual’s nutrition-related behaviors and choices.

3.7. Emotional and Psychological Aspects

Another notable constraint of ChatGPT is its limited capacity to effectively address emotional and psychological factors, which often demand a more empathetic and human approach [59][15]. For instance, individuals may struggle with issues such as stress, emotional eating, or disordered eating patterns, which necessitate a sensitive and understanding response. Research conducted by Cardoso et al. [65][22] underscores the value of individuals sharing their personal experiences and recognizing the intricate connection between emotions and dietary behaviors. Unfortunately, ChatGPT may not possess the same level of emotional support, empathy, and rapport-building capabilities as professionals do during nutrition counseling or interventions. Human professionals can leverage their empathetic skills to establish trust, offer emotional support, and tailor recommendations to an individual’s unique emotional and psychological needs, which is a level of interpersonal engagement that remains beyond the current capabilities of AI-driven platforms [66][23].

3.8. Wearable Device Integration

Numerous nutrition applications allow for the integration of wearable devices to collect real-time data on physical activity levels, vital signs, and other health metrics [48][3]. This seamless integration enables users to track their progress, gain insights into their overall health and wellness, and make informed decisions about their nutrition and lifestyle. For instance, a user with a wearable fitness tracker might be able to receive real-time feedback on their daily steps, heart rate, or calories burned through a nutrition app integrated with such a device. The app can tailor dietary recommendations based on this data, promoting healthier choices and better alignment with the user’s fitness goals. However, as ChatGPT operates as a text-based model, it cannot directly interact with or interpret data from wearable devices. This limitation prevents ChatGPT from leveraging real-time information and offering tailored feedback based on physiological data.

3.9. Data Visualization

Another limitation of ChatGPT is the ability to display data using graphs, charts, and dynamic visuals. Nutrition apps often provide intuitive visual reports that display data on a user’s dietary habits, exercise routines, and health metrics over time. These visual representations empower users to grasp their progress more effectively and make data-driven decisions regarding their nutrition and fitness goals. ChatGPT, on the other hand, primarily relies on text-based communication, making it challenging to offer such visual reporting capabilities. This limitation is pivotal because visual feedback can be a powerful motivator, allowing users to see their achievements and areas for improvement instantly.

3.10. Ethical and Privacy Concerns

Numerous healthcare studies, e.g., [67[24][25][26],68,69], express concerns about the ethical implications and raise privacy issues that are also applicable to the nutrition domain. Unlike human professionals, ChatGPT lacks the innate ethical awareness and sensitivity required to responsibly manage personal information. Nevertheless, engaging with ChatGPT involves divulging personal health data, dietary habits, and other sensitive information to ensure accurate nutrition-related guidance. For instance, when individuals interact with ChatGPT to discuss their dietary habits, allergies, or health conditions, they entrust this information to the system. Consequently, ensuring the privacy and security of this data becomes crucial to protect individuals’ confidentiality and maintain the trust of users in the system. Such measures may include data encryption, access controls, and compliance with relevant data protection regulations to assure users that their personal information is handled responsibly and ethically. It is noteworthy that this necessity for stringent data protection measures is not unique to ChatGPT. Other nutrition apps face a parallel demand for safeguarding user information [70][27]. To maintain the trust of their user base and adhere to privacy standards, these nutrition applications also need to implement robust data security practices, including encryption, user authentication, and compliance with data protection regulations, such as GDPR or HIPAA, whenever applicable.
