The goal of this clinical trial is to learn whether adding either cardiovascular exercise or resistance exercise to pharmacotherapy treatment for obesity improves the retention of lean mass compared to pharmacotherapy alone in adults with overweight or obesity who are prescribed pharmacotherapy for obesity treatment by their personal physician. It will also provide information about whether either form of exercise added to pharmacotherapy for obesity treatment has additional benefits on other health and fitness measurements. The main questions it aims to answer are: * Is there a difference in the change in total lean body mass between pharmacotherapy alone and either pharmacotherapy plus cardiovascular exercise or pharmacotherapy plus resistance exercise? * Is there a difference in the change in muscle mass between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in muscle quality between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in body weight between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in body composition (fat mass, fat mass distribution) between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in cardiorespiratory fitness between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in muscle strength between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in physical function between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in bone mineral density between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in bone biomarkers between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in resting blood pressure between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in energy intake between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there a difference in the change in physical activity between the intervention conditions (pharmacotherapy alone, pharmacotherapy plus cardiovascular exercise, pharmacotherapy plus resistance exercise)? * Is there an effect of sex, race/ethnicity, age, menopausal status, obesity management medication type, or other demographic characteristics on the outcomes that are being measured. * What is the extent to which the retention of lean body mass or muscle mass mediates the effect of exercise on weight changes. Participants will: * Initiate and continue throughout the study period an eligible obesity management medication that is prescribed by their healthcare provider, and to report their adherence to this medication to the investigators. * Participant in this study for a period of 6-8 months to complete outcome assessments that occur at baseline and at the conclusion of 6 months of the intervention period, and monitoring visits that occur at weeks 3, 6, 9, 12, 15, 18, and 21. * If attend 3 supervised exercise sessions per week if assigned to either the cardiovascular exercise intervention or the resistance training intervention for a period of 24 weeks.

This prospective single-arm feasibility study evaluates the Adhera Caring Digital Program for Obesity (ACDP-O), a family-centered digital health intervention designed to support adolescents and young adults with overweight/obesity and chronic conditions, including type 1 diabetes (T1D) and asthma. The intervention combines personalized educational content, wearable-device monitoring, psychometric assessments, and explainable artificial intelligence (AI) to improve mental well-being, quality of life, and adherence to healthy lifestyle behaviors. A total of 280 families will participate in a 3-month intervention with remote monitoring and follow-up assessments.

Although type 1 diabetes (T1D) has traditionally been considered a disease associated with a lean phenotype, it is estimated that up to 2 out of 3 people living with T1D are overweight or obese, factors linked to an increased risk of complications in these patients. The available evidence regarding nutritional strategies for weight loss in T1D is very limited, and clinical trials are needed to determine how to effectively and safely promote weight loss in this population. In recent years, low-carbohydrate diets and several intermittent fasting protocols have demonstrated efficacy in promoting weight loss both in patients with type 2 diabetes and in patients with obesity without diabetes. In this study, we will evaluate the efficacy of moderate carbohydrate restriction, time-restricted eating, and standard calorie restriction for weight loss in adults with T1D and overweight/obesity.

Who can participate? Individuals may be eligible to join this study if they meet the following criteria: * Are 18 years or older. * Have Type 2 diabetes with an A1c level higher than 7%. * Have a Body Mass Index (BMI) between 27 and 35 (considered overweight or Class 1 obesity). * Have used a continuous glucose monitor (CGM) successfully in the past. How the study works: If eligible individuals decide to join and sign the consent form, a computer will randomly assign them into one of two groups: The Formula Group: Participants will replace their usual breakfast and one snack with a specific diabetes nutritional drink (Glucerna®). The Standard Diet Group: Participants will follow a standard low-calorie meal plan without using the nutritional drink. Both groups will aim for a specific daily calorie goal (1,200-1,500 for women; 1,500-1,800 for men) and will receive expert nutritional counseling. Monitoring and Follow-up Over the course of 3 months, close contact will be maintained to support participants: Every 2 weeks: A nutrition expert will call participants to check on their diet and help with their glucose monitor. Every month: Participants will meet with the study team in person to review glucose monitor data. Tests: At the start and end of the study, weight, body composition, blood sugar (A1c), and cholesterol levels will be measured to see how the plans worked.

The primary objective is to assess the safety and tolerability of oral dose ERX1000 in obese subjects.

The goal of this clinical trial is to learn if a digital lifestyle education program improves exercise capacity in adults who have heart failure with preserved ejection fraction (HFpEF) and overweight or obesity. HFpEF is a type of heart failure in which the heart muscle is stiff and does not relax well, even though its pumping strength looks normal. The main questions it aims to answer are: * Does the program improve how much oxygen participants can use during exercise, a measure of fitness, after 6 months? * Does the program improve participants' quality of life and help them lose weight? Researchers will compare a group that uses the digital program plus usual care to a group that receives usual care alone. This will show whether the program adds a benefit. Participants will: * Be placed by chance into one of the two groups * Use a study website with short videos on exercise, healthy eating, and managing stress (program group), with new content every week for 6 months * Have exercise tests, an ultrasound scan of the heart, blood tests, and complete a quality-of-life questionnaire at the start and after 6 months Both groups will keep taking their usual heart failure medicines.

Numerous plant-based foods contain bioactive compounds, in particular polyphenols, which have antioxidant, anti-inflammatory, and metabolic regulatory effects. These so-called food bioactives (FB) are converted in the human organism, in particular by the gut microbiota and microsomal (liver/intestinal) metabolism, into numerous metabolites, which often represent the actual biologically active molecules. As part of the European HORIZON-MSCA Doctoral Network "BioTransform," two such food models are being studied as examples: 1. Olive products (Olea europaea L.) - representative of the Mediterranean diet, rich in secoiridoids and phenylethanols (especially hydroxytyrosol and tyrosol). 2. Bilberry /blueberry (Vaccinium myrtillus L.) - representative of the Central European diet, rich in anthocyanosides. Two parallel human intervention studies will be conducted, one in Graz (WP1, DC5) and one in Athens (WP1, DC3). These pilot studies will generate biological samples (blood, urine, stool) and investigate the extent to which taking these standardized dietary supplements influences glucose metabolism and markers of oxidative stress and low-grade inflammation.
