Approximately 500 million people have Type 2 Diabetes Mellitus (T2DM) in 2018 and it is expected to increase between 20% and 50% over the next 10 years. T2DM is also called non-insulin-dependent or adult-onset, and it results from the body's ineffective use of insulin, being the result of excess body weight and physical inactivity. Diabetes is the 7 leading cause of death by increasing the risks of cardiovascular and other diseases, many of which (43%) occur prematurely and are largely preventable through adoption of policies to create supportive environments for healthy lifestyles.~Therefore, improving the implementation of health-related education programs through nutrition and physical exercise is a key tool for behaviour change. The combination of physical exercise and nutritional counselling is known to improve the impact on both body composition and health in general population and in T2DM; however, the adherence of those programs is compromised and even if the complete intervention is performed by the patient, we can find non-responders. The underlying mechanisms that determine the impact of educational program focused on healthy lifestyles could be explained by molecular and physiological responses to the interventions. In this sense, hormones that regulate appetite and exerkines could impact on food preference, decision making, and in the exercise impact on appetite, consequently, modifying dietary intake, body composition and health.~Exosomes (EX) have been considered as novel and potent vehicles of intercellular communication and exert the remarkable effects on lipid metabolism, including the synthesis, transportation and degradation of the lipid. EX have been proposed as a mechanism for the physiological effects of physical exercise in patients with T2DM.~According to previous scientific research, we hypothesize that the combination of a nutritional education intervention with a physical exercise program improves appetite regulation mediated by exosomes in people with T2DM, leading to better glycaemia/insulinaemia levels, reduction of body fat mass and quality of life.~The project is a randomized controlled clinical trial in 120 participants with T2DM and obesity, which aims to determine the efficacy of a nutritional education program and the role of physical exercise type on health related variables. The participants will be of both sexes with age between 40 and 55 years, belonging to the Province of Cádiz. The design has two 12-week interventions; the main factor has 2 levels: participants who receive the nutritional education (EDU) and controls (CG); the second factor has 3 levels: high-intensity interval training (HIIT), moderate intensity continuous training (MICT), and controls (INACT). Therefore, participants will be randomized into 6 groups (n=20), adjusted by gender (≈50% in each group): EDU+HIIT, EDU+MICT, EDU+INACT, CG+HIIT, CG+MICT, CG+INACT.~The outcome variables, which will be measured before and after the intervention, will include: dietary intake assessment, physical activity assessment, quality of life, blood samples, emotional reactivity to food images, blood pressure, appetite assessment, body composition and fluids, basal metabolism, maximal fat oxidation test and cardiorespiratory fitness.
