Filter by:The purpose of this study is to determine the effectiveness of a physician led, multi-disciplinary approach to treating obesity that incorporates nutrition (mainly, using genetics to identify appropriate food intake), exercise, and motivational counseling. We plan to recruit overweight/obese (BMI>25) males and females to participate. Participants will be randomized to receive a personalized diet plan, or a standard care diet plan; both groups will participate in the exercise intervention. For a 6-month duration, both groups will be asked to improve their diet according to their dietary plan and participate in moderate-to-vigorous physical activity (gradual increase up to 300 min/week). We intend to evaluate standard outcomes of weight loss, and assess for any predictors of positive outcomes. Following the six-month intervention, participants will complete a 3-month no contact phase. This no contact phase will provide insight into the effects of the study on weight loss maintenance. Our team also plans to address acceptability by providing evaluations to study participants and conducting interviews with a small subset of participants to improve the intervention for the future.
Background: Overweight and obesity affect health, quality of life and ability to work. Therefore, the Low-Insulin-Method was developed to support overweight and obese people in weight loss. Method: In a randomized controlled clinical trial, the effect of the lifestyle intervention program 'Low-Insulin-Method', delivered by the Low-Insulin-App including low-carb diet, self monitoring of weight, physical activity and telemedical coaching is examined compared to a control group without coaching. The learning contents are taught in 30 videos and 5 online meetings. The intervention group additionally gets 4 individual care calls. The state of health is examined at the beginning and after 12 weeks. Objective: The aim is to develop a training and counseling program for overweight or obese individuals with diabetes risk or type 2 diabetes, which can be used both for primary and for tertiary prevention of overweight-related diseases.
Obesity, affecting 40% of US adults and costing 173b annually, represents a significant health care burden (1). It is associated with increased risk for multiple chronic diseases including hypertension, type 2 diabetes (T2D), cardiovascular disease, and NAFLD, as well as cancer, osteoarthritis, and obstructive sleep apnea. The investigators plan to test the hypothesis that tirzepatide, a dual GLP/GIP agonist, improves metabolic health (insulin resistance and regional fat distribution and cardiovascular risk profile) not only by inducing weight loss via GLP1-agonism, but also via beneficial cellular and molecular changes in adipose tissue, given that GIP binds receptors in human fat cells. Based on studies in mice showing that GIP alone or tirzepitide treamtent decreases inflammation, increases lipid buffering (fat storage in the fat cells instead of releasing it into the bloodstream), and improves glucose homeostasis. The investigators believe that the GIP component of tirzepatide will make fat cells healthier and reverse lipotoxicity, which is one of the mechanisms by which obesity leads to insulin resistance, disordered regional fat distribution, and type 2 diabetes. To date, the effect of dual GLP1 and GIP agonist treatment on adipose tissue has not been evaluated in humans. Given the existing but limited data, dual GIP/GLP-1 agonist treatment in obese humans with metabolic risk factors is an attractive pharmacologic candidate that would lead to both weight loss and healthier fat, potentially offering uniquely powerful synergistic clinical benefits. It is thus of tremendous importance to define the biological effects of dual-agonist treatment on human adipose tissue structure and function, as well as related improvements in regional fat distribution and systemic adipose and muscle insulin sensitivity. In this study, the investigators will randomize overweight (with risk factors) or obese nondiabetic individuals to hypocaloric diet or tirzepatide for 22 weeks with matched weight loss for the first 6 weeks. The investigators will quantify insulin resistance, fat and lean mass, including regional fat distribution, and changes in adipose tissue (needle biopsy from abdominal fat tissue) to see if tirzepatide effects differ from dietary weight loss.
The investigators hypothesize that weight loss obtained with the French RNPC weight reduction program is beneficial for the general health of overweight/obese patients in the medium term. The objective of this cohort study is to demonstrate the effectiveness of the RNPC program on the reduction of drug or instrumental treatments (for example, continuous positive pressure ventilation for the treatment of sleep apnea syndrome) and the improvement of overweight/obesity-associated comorbidities in the medium term. This is a multicenter clinical study, as part of routine care, with standardized nutritional care (RNPC Program) in all RNPC centers in France. A cohort will be formed based on the clinical and biological data usually collected in the centers, enriched by data from additional clinical and biological examinations as well as by self-questionnaires completed by the participants. About 10,000 overweight or obese participants will be included for 2 years and followed 5 years. The SCOOP-RNPC study will have benefits for individual participants, for the scientific community in terms of knowledge acquired and for society with a better definition of the impact of treatments. Responding to the major public health issue represented by overweight, this prospective cohort of overweight or obese patients will make it possible to evaluate, in real-life conditions, the effects of weight loss obtained by the RNPC Program in the short, medium and long term on biological parameters predictive of cardiometabolic risk, drug consumption, quality of life, diet and eating behavior, sleep, physical activity, stress/anxiety, as well as depression. This cohort will make it possible to identify clinical phenotypes and biomarkers to optimize the personalization of the management of overweight or obese patients, in particular those at risk of developing comorbidities associated with excess weight.
The study aims to implement a 12-week home-based exercise programme utilising an online intervention delivery platform. The focus will be on increasing exercise behaviour within the participant's home setting using aerobic, resistance and flexibility exercises as well as behaviour change techniques. Following the programme, semi-structured interviews will be conducted, to explore participant experiences. It is hypothesised that the exercise programme will be feasible, accessible and acceptable.
The purpose of this pilot study is to conduct a 12-week pilot feasibility study testing usability of a reinforcement learning model (AdaptRL) in a weight loss intervention (ADAPT study). Building upon a previous just-in-time adaptive intervention (JITAI), a reinforcement learning model will generate decision rules unique to each individual that are intended to improve the tailoring of brief intervention messages (e.g., what behavior to message about, what behavior change techniques to include), improve achievement of daily behavioral goals, and improve weight loss in a sample of 20 adults.
This study investigates the safety and efficacy of sodium pentaborate pentahydrate in improving the body weight and glycemic profile of patients with overweight or obesity compared to the placebo group.
The primary aim of this study is to investigate the acute changes in liver fat content in response to a fixed carbohydrate restriction (i.e. intake of 60g/day or 70g/day for women and men, respectively) in individuals with obesity. This will be performed both as 2 days of very low calorie diet (500 and 600 kcal/day for women and men, respectively) and 2 days of eucaloric low carbohydrate diet.
Obesity and overweight are noncommunicable diseases with increasing incidence in children, adolescents and adults. In 2016, more than 1.9 billion adults aged 18 and over were overweight and over 650 million were obese (WHO). In the EU-27 (Eurostat data), 45.7% of women and 60.2% of men were overweight, while 16.3% and 16.8%, respectively, were obese. The growing incidence of overweight and obesity generate worldwide increasing incidence of related conditions as cardiovascular diseases, diabetes, metabolic disorders, and cancer, with relevant socio-economical (increase in health costs, increase in disabilities) and environmental consequences (unsustainability of food models, increase in ecological footprint, worsening of climate changes). A transformation of food systems and individual behaviours are necessary to improve the quality of life and the sustainability of lifestyle, which should be oriented at preventing o treating overweight and obesity.
The primary aim of the present study is to record changes in the health-related quality of life (HRQoL) of children/adolescents participating in the multi-professional group programme 'kinderleicht' in 2022 over the course of the eleven-month active phase. In addition, these data will be examined for correlation with changes in BMI, waist and hip circumference, and motor performance. Secondarily, the study addresses the questions of whether the recording of HROoL by means of the KINDL questionnaire is practicable for the programme leaders and what benefit can be gained from the analysed data for future cohorts.
