###### Abstract  
The prevalence of diet-related diseases underscores the imperative for innovative management approaches. The deployment of smart solutions signifies a paradigmatic evolution, capitalising on advanced technologies to enhance precision and efficacy. This paper aims to present and explore smart solutions for the management of diet-related diseases, focusing on leveraging advanced technologies, such as connected care, the Internet of Medical Things (loMT), and remote health monitoring systems (RHMS), to address the rising prevalence of diet-related diseases. This transformative approach is exemplified in case studies focusing on tailored RHMS capabilities. This paper aims to showcase the potential of three RHMS in introducing a novel evaluation method and their customisation for proactive management of conditions influenced by dietary habits. The RO-SmartAgeing System uniquely addresses age-related aspects, providing an integrated approach that considers the long-term impact of dietary choices on ageing, marking an advanced perspective in healthcare. The NeuroPredict Platform, leveraging complex neuroinformatics, enhances the understanding of connections between brain health, nutrition, and overall well-being, contributing novel insights to healthcare assessments. Focused on liver health monitoring, the HepatoConect system delivers real-time data for personalized dietary recommendations, offering a distinctive approach to disease management. By integrating cutting-edge technologies, these smart solutions transcend traditional healthcare boundaries. remote health monitoring systems; integrated insights; advanced evaluation; liver cirrhosis; schizophrenia; tailored patient-centric approach +

* _Obesity:_ Obesity has reached epidemic proportions worldwide. It is linked to various health issues, like heart disease, type 2 diabetes, certain cancers, and musculoskeletal disorders [1]. Poor dietary choices, high caloric intake, and lack of physical activity contribute significantly to its prevalence. * _Type 2 Diabetes_: often associated with obesity, type 2 diabetes occurs mainly as a result of insulin resistance or, in selected cases, inadequate pancreatic insulin secretion [2], and is heavily influenced by dietary patterns, particularly high sugar and refined carbohydrate consumption [3]. * _Cardiovascular Diseases_: Diet plays a pivotal role in cardiovascular health [4]. High intake of saturated and trans fats, excessive salt, and low intake of fruits, vegetables, and whole grains contribute to conditions like hypertension, coronary artery disease, and stroke. * _Certain Cancers_: while genetics and environmental factors play a role, diets high in processed foods [5] and red meat and low in fruits, vegetables, and fibre are associated with increased cancer risk, particularly colorectal, breast, and prostate cancers. * _Osteoporosis_: inadequate intake of calcium and vitamin D, often due to poor dietary choices or malnutrition, can contribute to osteoporosis [6], weakening bones and increasing fracture risk, especially in older adults. * _Mental Health Disorders_: Emerging research suggests a link between diet and mental health [7]. Diets high in processed foods and sugars may contribute to increased risks of depression and anxiety [8], while diets rich in fruits, vegetables, and omega-3 fatty acids may have protective effects. * _Malnutrition_: while obesity is a concern, malnutrition due to inadequate intake of essential nutrients is also prevalent in some populations, leading to deficiencies in micro- and macronutrients with a significant impact on overall health [9]. In 2001, chronic diseases accounted for approximately 60% of deaths worldwide, almost half of them being attributed to cardiovascular diseases.
