Obesity Clinical Trial - A Personal Nutrition Advisor to Assist Remote

Status Completed

Clinical Trial Summary

The purpose of the study is to assess the usability of the PNA and satisfaction with the treatment within the framework of usual care remote nutritional counselling for GLP-1-supported weight management and collect pilot data on its potential to support weight loss.

Clinical Trial Description

The global prevalence of obesity and overweight is increasing and persistently drives global mortality and morbidity.As overweight and obesity are the result of an imbalance between energy intake and energy use, achieving a negative energy balance build the foundation for weight loss. Whilst dietary modification as a standalone procedure often fail in achieving or maintaining weight loss, the recent advent of supportive Glucagon-like Peptide-1 (GLP-1) based pharmacotherapies have greatly changed the landscape.Dietary counselling help people on GLP-1 based treatment reaching their individual weight goals and continued reimbursement of medication costs. However, nutritional advice provided by dietitians is often generic, not sufficiently aligned to individual weight loss trajectories. The "Personal Nutrition Advisor" (PNA) is a decision support tool which is built upon an interpretable weight prediction model based on the energy balance equation (energy intake is a function of recorded dietary intake and a latent part dependent on observed weight changes, whereas energy expenditure is a function of weight and physical activity). Food, weight- and activity records captured using a smartphone application represent input data to the model. Output of the model is the predicted body weight trajectory alongside with personalized recommendations to reach a pre-defined target weight. Integrating the PNA into a remote dietary counselling programme, in which certified dietitians deliver nutritional and lifestyle coaching via an application, has the potential to improve treatment satisfaction and efficacy. Therefore, the purpose of the study assess the usability of the PNA and satisfaction with the treatment within the framework of usual care remote nutritional counselling for GLP-1-supported weight management and collect pilot data on its potential to support weight loss. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
