Active clinical trials for "Obesity, Metabolically Benign"

Obesity-related cardiometabolic diseases are now a leading cause of death worldwide. These diseases result from a dysfunctional adipose tissue (AT) that induces inflammation, insulin resistance and altered endocrine function. However, not all obese people develop metabolic complications, which has given rise to the concept of "metabolically healthy obesity" (MHO). Recent evidence suggests that intermittent fasting methods, in particular time-restricted eating (TRE) may be effective in improving cardiometabolic health, independently of weight loss, and this could be particularly effective in MUO subjects. The investigators hypothesize that in young male adults TRE is a more effective/beneficial approach in MUO than in MHO due to the weight loss-independent improvement in their inflammatory and metabolic derangements. To this aim, a 16-week 8h TRE intervention study will be performed in MHO and MUO subjects, assessing anthropometric, endocrine, and other outcomes.

Strategies to reduce sugar-sweetened beverages (SSB) have become one of the leading public health targets to address the epidemics of obesity and diabetes. National food, nutrition, and health policies and programs have positioned low-fat milk as the preferred caloric replacement strategy for SSBs. This strategy derives from evidence that replacement of SSBs with low-fat milk is associated with reductions in weight and incident diabetes in prospective cohort studies and reduces liver fat (an important early metabolic lesion linking obesity to diabetes), as well as triglycerides and blood pressure in randomized trials. Whether these benefits hold for soy milk alternatives is unclear. There is an urgent need for studies to clarify the benefits of soy milk as an alternative to cow's milk. Our overarching aim is to produce high-quality clinical evidence that informs the use of soy as a "public health intervention" for addressing the dual epidemics of obesity and diabetes and overall metabolic health. To achieve this aim, we propose to conduct the Soy Treatment Evaluation for Metabolic health (STEM) trial, a large, pragmatic, randomized controlled trial to assess the effect of using 2% soy milk (soy protein vehicle) versus 2% cow's milk (casein and whey vehicle matched for protein and volume) as a "public health intervention" to replace SSBs on liver fat and key cardiometabolic mediators/indicators in an at risk population.

The goals of this research study are to: 1) understand why some people with obesity are protected from developing conditions such as type 2 diabetes and cardiovascular disease while others are more likely to develop obesity-related conditions; 2) assess the effect of small extracellular vesicles (sEVs also called exosomes), obtained from human participants, on metabolic function in cultured cells and in mice.

Introduction: Cardiopulmonary exercise test (CPET) is a helpful tool for evaluation of aerobic exercise capacity and tolerance for variety of population. The test progression include an incremental stepwise or ramp control protocol to exhaustion There are different methods used in various clinical setting. CPET involves the measurement of respiratory gas exchange i.e. oxygen uptake, carbon dioxide, minute ventilation, other variables while monitoring ECG, blood pressure, pulse oximetry and exertion perceived (Borg Scale) during an incremental test on a cycle-ergo meter or treadmill. This test allow to assess an integrative exercise responses to submaximal and maximal effort. Aim: To compere exercise responses and achieved criteria for maximal exercise testing with different exercise protocol Methods: Healthy volunteers (normal and overweight ) will be recruited to participants in the study. Demographics (age, sex), anthropometric (height, weight, abdominal circumference), will be measured. By using questionnaire, physical activity behavior and motivation toward engage in physical activity will be filled by the participants. Each participants will conducted an exercise test on treadmill (using Modified Bruce Protocol) and cycle ergometer. Quark CPET metabolic cart (Cosmed, Rome, Italy) will be used to collect and analysis gas exchange. 10 minute after the graded exercise test Supra maximal exercise test (SMT) will be done for 2 minutes one stage (treadmill protocol) or 10% at cycle protocol higher than highest load achieved in the incremental test. All exercise parameter done on the different ergometer will be compared

The investigators are examining the extent gut permeability explains observed inflammation in normal-weight and metabolically healthy obesity (and potentially cardiovascular disease risk).

In this is an observational study, obese patients that administed and followed in endocrinology clinic of Marmara University Medical school hospital will follow for clinical and laboratory parameters prospectively for 5 years

Objective To study if exercise added to weight loss treatment at the beginning of the weight loss intervention or at 6 months could sustain the weight loss achieved or give extra boost for weight reduction. Design 36-month, 4-group parallel, randomized trial. Setting Oulu, Finland. Participants 120 obese adults (body mass index ≥ 30). Intervention Participants were randomly assigned to behavioural modification (iBM) (n = 30), behavioural modification + exercise from 0 to 3 months (CWT1) (n = 30), behavioural modification + exercise from 6 to 9 months (CWT2) (n = 30), and a control group (CON) (n = 30). Questionnaires and measurements were performed at baseline, 3,9,4 and 36 months. The intervention consisted of an intensified weight loss period (1-12 months) followed by a weight maintenance period (13-36 months). Intensified behavioural modification included 14 individual face to face meetings, eleven times with a personal therapist (qualified nurse) and three times with a nutritionist. Weight maintenance period included six individual meetings with personal therapist. Twelve weeks supervised exercise was offered three times a week, 40 minutes at a time. In the CWT1 group supervised exercise was offered at months 1-3 and in the CWT2 group at months 4-6. Measurements Body weight (primary outcome) and waist circumference (secondary outcome)

The current protocol aims to investigate the impact of the propionate ester in conjugation with restricted diet on appetite and weight loss.

Purpose: The purpose of this study would be to evaluate the effects of interval training on cardiovascular health, lipid profile and body composition in overweight and obese men and women. A secondary purpose will be to compare lab based measurements of body composition [4-compartment model (4C)) with portable equipment [bioelectrical impedance spectroscopy (BIS) and ultrasound (US)] Participants: Seventy-six men and women (age 18-55 yrs; BMI 25-45 kg/m2) will be randomly assigned to a high-intensity short interval group (SIT), high-intensity long interval group (HIT) or a control group (CON). Procedures (methods): Participants will be assessed for peak oxygen utilization (VO2peak), blood lipids, glucose and insulin levels. Body composition will also be measured using a 4C model, as measured from dual energy x-ray absorptiometry (DEXA), air displacement plethysmography (BodPod), and BIS, in comparison to US values. Participants assigned to either training group will undergo 3 weeks of interval training, 3 days per week. SIT will complete 10 bouts of a series of 1 min cycling with 1 min rest periods at 90% of the power output obtained during VO2peak;in comparison HIT will complete 5 bouts of the same protocol: 2 min bouts with 1 min recovery at varying intensities of VO2peak (80-100% power output).

The level of fibre consumption in France is lower than the national and international recommendations (mean 18.8 g/d for men, 16.4 g/d for women (INCA 2007 Study) instead of 30g/d recommended). Fibre have beneficial effects on health and interact with the intestinal microbiota diversity: a diet fortified with different structure fibres increase of 25 % the dysbiotic intestinal microbiota in obese patient (Cotillard et al, Dietary intervention impact on gut microbial gene richness. Nature, August 2013). The study aim is to evaluate the impact of daily consumption of bread (150 g ) enriched with a mixture of fibres of different structure (15g) during two months on the intestinal microbiota composition in metabolic risk subjects (abdominal overweight or obese) and also, to assess the correlation between the microbiota change and their metabolic profile improvement.It is a mono centric study with a centre in LYON (Centre de Recherche en Nutrition Humaine Rhône-Alpes)
