What this Trial Is About
Researchers are evaluating a digital Healthy Lifestyle Recommender Solution (HLRS) designed to help men and women aged 60 years or older improve their lifestyle habits to prevent obesity and related health problems. This pilot study aims to assess how well participants accept and use the HLRS app over a 3-month period, focusing on its user-friendliness and adherence. It also explores the feasibility of the study design and gathers preliminary data on lifestyle changes and biological markers linked to obesity risks. Participants will use the HLRS app and take part in several study visits, including enrollment, baseline, intermediate follow-up, and final visits. During these visits, researchers will collect anthropometric measurements, biological samples (blood, urine, stool), and questionnaire data on diet, physical activity, and well-being. The intervention aims to motivate healthier habits through personalized recommendations and digital support. Throughout the study, participants will be regularly assessed for adherence to the HLRS app and their experience using it. Researchers will measure changes in body mass, body fat, physical activity patterns, dietary habits, and selected biochemical markers. The study includes questionnaires and biological sample collection to evaluate lifestyle and health indicators. Participation lasts approximately three months, with ongoing monitoring to support data collection and ensure participant engagement.
