Active clinical trials for "Overweight"

Normal body iron store value in overweight subjects is currently not described in literature. The comparison of this value with body iron levels in patients suffering from dysmetabolic iron overload syndrome (DIOS) could allow to quantify iron overload in this condition. The purpose of the study is to determine iron levels in healthy overweight volunteers, and to compare them to DIOS patients treated with phlebotomy.

Primary Objectives: To assess in overweight to obese T2DM patients: The glucagon receptor occupancy of SAR425899 at two dose levels in the human liver with positron-emission tomography (PET) imaging using [68Ga]Ga-DO3A-VS-Cys40-Tuna-2 as a tracer compound. The GLP-1 receptor occupancy of SAR425899 at two dose levels in the human pancreas with PET imaging using [68Ga]Ga-DO3A-VS-Cys40-Exendin-4 as a tracer compound. Pharmacodynamic effects on fasting plasma glucose and biomarkers of lipid metabolism. Pharmacokinetic parameters for SAR425899 after repeated subcutaneous (SC) doses in plasma. Safety and tolerability of SAR425899.

A randomized cross-over design aims to investigate chewing activities between healthy vs. overweight and determine effects chewing times on energy intake and postprandial plasma glucose and insulin. Forty-one participants were allocated into lean and overweight groups according to BMI. Phase I, Bite size (g/bite), bite rate (bites/min), chewing frequency (chews/min), and chews (chews/g food) were recorded after a sandwich breakfast. Phase II, gram of sandwich eaten ad libitum after 15 and 50 chew per bite (number from phase I) were recorded. Postprandial plasma glucose and insulin were examined at 0 (baseline), 30, 60, 90, 120 and 180 min.

The purpose of this study is to evaluate the satiating effects of different canned tuna preserved in olive oil enriched with soluble fiber or polyphenols on overweight subjects (BMI ≥25 and <30 kg / m2). Some studies have shown the contribution of high-fiber foods in the reduction of the cardiovascular risk.

The PERGROUP trial aims to investigate whether Web-based personal or Web-based group counselling weight management program can help to achieve lifestyle changes needed for weight loss and improvement in quality of life and cardiovascular risk factors. The control group is the traditional nurse-lead weight management group counselling.

The study evaluates the effect of exercise and/or diet during on body weight, body composition and health related blood parameters. Participants are overweight sedentary females, allocated to four different groups: Normal diet, Low-carb-high-fat diet, Normal diet + exercise, Low-carb-high-fat diet + exercise.

A study to address the effects of early-day fasting on fat tissue mobilization in comparison to a typical isocaloric Mediterranean and a low-carbohydrate breakfast.

The purpose of this research is to determine the blood signals that promote health and well-being in response to exercise at different intensities.

The central research question aims to understand what drives individuals to make and maintain a vegan / vegetarian dietary decision, to investigate whether there are possible predictors that might influence such a decision and whether personality differences already exist or can only be measured after the change in diet. The investigators will examine the effects of a high-fiber diet on food wanting on a neural and on a behavioral level. The microbiome is suggested to mediate the expected changes in food wanting.

The TREAT Pilot is a 3 months open-label pilot study to examine the effect of restricting the duration of eating (Time Restricted EATing) in metabolically unhealthy adults with overweight or obesity. This pilot study will allow the investigator to collect preliminary data for the design of a larger study.
