### Possible Innovative Solutions Related to the Problem of Disease Management
* _Remote health monitoring systems (RHMS)_ encompass the technologies and systems used for remote monitoring of patients' health metrics. These systems often utilize IoMT devices to collect data on vital signs, medication adherence, activity levels, and other health-related information. RHMS allow healthcare providers to remotely track patients' health statuses, intervene if necessary, and make informed decisions about their care. These systems employ cutting-edge technology to collect and safely transmit real-time health data, enabling medical professionals to make decisions about residents' health, respond quickly to issues, and provide individualized care based on thorough knowledge gained from analysing and processing health data. Large-scale evidence of RHMS' enormous development and commercialisation potential was provided by the COVID-19 pandemic. They use their influence to increase access to medical care for a greater number of patients and offer insightful data for the patient profile that is updated regularly, contributing to medical research and development. Particularly for older and physically challenged patients, these devices hold a lot of potential [70]. In open or closed situations, several wearable sensors or health-monitoring sensors, including blood pressure, oxygen, pulse, and heart rate sensors, are utilized in RHMS to observe patients [71]. The caregiver or physician is alerted to any anomaly in the patient's behaviour, allowing them to take immediate action. Sensors based on computer vision techniques are also employed to monitor patients' health. * _Demand for novel evaluation methods_ has grown with the fast progress in IoMT, RHMS, and connected care, alongside the management of diet-related diseases. Novel evaluation methods that take advantage of the cutting-edge features made possible by connected care, IoMT, and RHMS are required to meet this prerequisite. These methods combine advanced data analysis, predictive modelling, and real-time monitoring to provide a more thorough comprehension of patients' health conditions and outcomes, as well as an in-depth awareness of their dietary habits and overall state of health. By merging these technologies, healthcare professionals can obtain a wide range of data from different sources, giving them the ability to use cutting-edge methods to evaluate the effectiveness of interventions and treatment plans. These advanced evaluation methods not only enhance the precision of treatment strategies but also foster a proactive approach, allowing for timely adjustments to dietary recommendations and interventions. These progressive methods of evaluation not only improve the accuracy of therapeutic strategies but also support proactivity, enabling prompt adjustments to dietary recommendations and therapies. The main objective of our paper is to present three RHMS that have been designed and developed by the authors of the paper, as well as how they can be customized for proactive management of conditions in which dietary habits influence both the disease progression and the treatment. Our three RHMS--RO-SmartAgeing System, NeuroPredict Platform, and HepatoConect System--provide innovative and adaptive capabilities, transforming customized diet-related disease management. This novel convergence of medical and IT domains not only improves comprehensive monitoring but also adds new aspects to the delivery of healthcare. The RO-SmartAgeing System distinctively addresses age-related aspects, offering an integrated approach to tailored solutions that take into account the long-term influence of dietary choices on ageing--an advanced perspective in healthcare. The NeuroPredict Platform, which uses complex neuroinformatics, provides a better knowledge of the multifaceted connections between brain health, nutrition, and general well-being, providing new insights into healthcare evaluations.
