Filter by:This clinical study aims to investigate the effects of TOTUM-63, a mix of 5 plant extracts, consumed at the daily regimen of three times per day, on cardiometabolic health and gut microbiota profile in overweight-obese individuals.
The prevalence of adults with overweight (50%) and obesity (15%) reached high number in Belgium. Important lifestyle behaviors, i.e. sleep, sedentary time (SB), and physical activity (PA) subdivided into light physical activity (LPA) and moderate to vigorous physical activity (MVPA), have shown an impact on overweight and obesity characteristics (e.g. adiposity). However, these behaviors have often been investigated separately. Therefore, a recent shift in research emphasizes the importance of considering these behaviors as part of a 24-hour day. Since these adults can benefit from an optimal 24-hour composition as part of a healthy lifestyle, it may be interesting to investigate the 24-hour movement composition among these adults. In addition, exploring different personal determinants, environmental determinants, and cardiometabolic markers will provide meaningful insights in developing an intervention.
This study will examine the feasibility and acceptability of a family-oriented augmentation of the Diabetes Prevention Program lifestyle intervention (DPP), called the Family DPP. It will also preliminarily examine adult and child health and health behavior outcomes. The DPP is a 12-month, group-based lifestyle intervention for adults at high-risk for type 2 diabetes, in which adult participants learn skills and strategies to achieve the program's goals of 5% weight loss and 150 minutes/week of moderate-vigorous physical activity. The Family DPP will consist of all elements of the evidence-based DPP, along with augmentations including additional child-focused sessions in which adult participants will learn about principles and strategies for promoting healthy lifestyle behaviors in children, ages 5 through 12 years. Children may participate in certain child-focused sessions, too. The non-randomized pilot feasibility study will consists of 2 arms/groups: 1) the concurrent "control" group, consisting of adults who are enrolled in the DPP; and 2) the "intervention" arm, in which the adult participants will engage in the Family DPP (and children may participate in certain aspects of the Family DPP focused on children). The study will recruit 10-15 adult-child dyads, for the "intervention" groups, and 10-15 adults for the concurrent control group. In addition to data collected from adult participants as a routine part of the DPP, the study will examine additional adult health behaviors and health outcomes and child health outcomes (change in body mass index z-score) and health behaviors at baseline, 6 months and 12 months (program end) among participants in the "intervention" group.
The purpose of this study is to investigate the effects of a fibre mixture added to a high-protein diet on metabolic, gut and brain health.
The investigators aim to test the hypothesis that a microbiome-changing dietary intervention improves food decision-making and to determine the underlying microbiotal and metabolic mechanisms. To this end, 90 overweight/obese adults will be enrolled in a randomized controlled trial to test the effects of a pre-biotic dietary intervention (supplementary intake of soluble fibre) or a behavioural lifestyle intervention (weekly educational program) vs. control condititon (supplementary intake of isocaloric starch) over a period of 26 weeks. Before and after the intervention/control period, participants will undergo task-based functional and structural MRI and cognitive testing. The gut microbiota will be assessed using 16S rDNA next-generation sequencing (V3/V4 region) in stool samples. Diet, anthropometry and lifestyle will be monitored with questionnaires and metabolomics will be assayed in peripheral blood and stool (e.g. SCFA). Using a modulation of gut-brain communication through a prebiotic diet and lifestyle intervention, respectively, the investigators will be able to discover microbiota communities that play a key role for eating behaviour. Related mechanistic insights could help to develop novel preventive and therapeutic options to combat unhealthy weight gain in our obesogenic society.
Overweight and obesity is becoming increasingly prevalent, constituting 64% of all adults in England, causing an incessant rise in cost to the National Health Service. Exercise and physical activity have the potential to reduce incidence of overweight and obesity, as well as improve obesity-related ill health. However, overweight and obese individuals are inherently sedentary and do not meet exercise guidelines. Same-session concurrent exercise training may be the most efficient exercise strategy to incorporate both cardiovascular- and strength-based exercise, both of which are vital for health-related benefits. This research project will aim to determine the feasibility of completing an 8-week concurrent exercise training programme in overweight and obese sedentary males. This study will aim to recruit adult males with a BMI above 25 kg.m2, who are otherwise healthy, but not regularly achieving exercise guidelines (less than 150 minutes of physical activity and 2 strength training sessions per week). Participants will undergo baseline and post-training testing of cardiorespiratory fitness, strength, heart and metabolic health, as well as a series of questionnaires and a semi-structured interview. They will then be randomised into one of two groups (high-intensity interval training or concurrent training) to complete twice-weekly exercise sessions for 8 weeks. The aims of this study are to evaluate the feasibility of performing 8-weeks of either concurrent, resistance or high-intensity interval training in overweight and obese males. This will be determined through assessment of cardiorespiratory fitness, strength, heart health, metabolic health, enjoyment, adherence and attendance.
South Asian men have lower cardiorespiratory fitness (CRF) than white men which is associated with a reduced capacity to oxidise fat during exercise. This is a risk factor for weight gain/regain. Whilst comparisons with Europeans are valuable, Asians are not a homogenous group and substantial differences in obesity and body fat partitioning exist with ethnicity. This cross-sectional pilot investigation aims to compare CRF and fat oxidation at rest and during exercise in Chinese, Indian and Malay men (from Singapore) with elevated BMI (23 -30 kg/m2). Forty-five men (15 each ethnicity) with elevated body mass index (23 -30 kg/m2) will complete testing in a fasted state on two separate mornings separated by ≥72 hours: (i) for a measure of CRF; and (ii) for a measure of fat oxidation at rest and during incremental exercise.
In recent years, dietary supplement are of great interest for the improvement of human health. This study is designed as a parallel, randomized, double blind study exploring the efficacy of two months daily oral dosing of five different food supplements together with diet restriction in 120 otherwise healthy overweight or obese adults on different biochemical and anthropometric parameters.
The cornerstone in the initial treatment of type 2 diabetes (T2D) is lifestyle modification, involving-among other things-a healthy diet. However, scientific evidence regarding optimal nutrition therapy for patients with T2D is insufficient. This clinical study will examine the effect of a carbohydrate-reduced high-protein (CRHP) diet compared to a conventional diabetes (CD) diet for 12 months on metabolic function and body weight in patients with T2D. The hypothesis of the study is that the CRHP diet will improve metabolic control and the cardiovascular risk profile of patients with T2D to a greater extent than the CD diet. In particular, the expectation is that, compared with the CD diet, the CRHP diet will: - Reduce diurnal and postprandial glycemia measured by continuous glucose monitoring (CGM) and thereby facilitate a significant reduction of glycated hemoglobin (HbA1c) - Reduce body weight - Reduce ectopic fat deposition in the liver and the pancreas - Improve the blood lipid profile - Reduce or not affect blood pressure with no adverse effect on heart rate variability - Increase insulin sensitivity and secretion - Decrease inflammatory markers in the blood - Improve satiety - Reduce or not affect the need for antidiabetic, antihypertensive and/or lipid-lowering medications To reinforce the results and knowledge generated from the primary study, participants will be invited to partake in a 12-month follow-up period after the initial 12 months of intervention.
This two-group RCT, the Mindful-Healthy Family project, will test the feasibility and preliminary efficacy of a mindfulness-based Motivational Interviewing (MM-based-MI) intervention with rural families within Michigan. This two-group RCT will enroll 34-60 families from Michigan rural or suburban communities with one OW/O parent-figure adult (BMI ≥25) who has at least one child (ages 3-6) at home. The targeted parents will serve as the change agent. The outcome assessments include BMI and optional hair cortisol as well as parent's collective family efficacy, perceived stress, depression score, 24 hours dietary recall (ASA24; healthy eating index [HEI]), mindful eating score, Physical Activity (IPAQ-short) at both baseline and post-intervention. These intervention group families will receive 9 online sessions (30 min/session) delivered via Zoom or phone calls every other week by trained research staff. BMI will be obtained directly from the participating parents using the scale delivered to their homes. Attention control arm families will have same assessment and will receive a total of 9 mailed packets of educational materials. This work will advance the science by explicating how MM and MI work synergistically.
