Filter by:The purpose of this study is to develop and test the feasibility of a behavioral weight loss intervention that uses personalized recommendations for diet and physical activity behaviors in a behavioral weight loss program and to explore factors associated with treatment adherence and response. The 12-week intervention will utilize digital tools for self-monitoring and counseling by weight management professionals. Exploratory analyses will be conducted to determine if there are genetic, metabolomic, microbiome, or psychosocial factors associated with treatment response.
Developing more efficient and cost-effective prevention strategies to slow down the worldwide epidemic of obesity and chronic metabolic disease has become a public health imperative. Our previous results in humans demonstrate that lower breast milk betaine levels were associated with faster infant postnatal growth, a strong and potentially modifiable risk factor of future obesity. Betaine is a trimethylated derivative of glycine, which is present in multiple foods and occurs naturally in breast milk. In this study, we will perform a double-blind randomized placebo-controlled pilot clinical study, in which maternal diet will be supplemented with betaine for 3 months during breastfeeding; infant's growth and adiposity will be monitored until 12 months of age, and breast milk composition and gut microbiota analyzed.
The purpose of this study is to investigate the effects of green tea extract (GTE) on fat oxidation, body composition and exercise performance in overweight individuals. The study will be conducted under laboratory conditions following an 8 week supplemental period. Participants will be required to attend the laboratory for a pre-screening/familiarisation trial followed by assessments at week 0 (baseline), week 2, 4 and 8. Across the intervention, participants will maintain habitual dietary intake and follow a prescribed exercise programme. Additionally participants will be randomised to either a placebo, green tea extract or GTE with antioxidant supplementation. It is hypothesised that the addition of antioxidants with GTE will enhance fat oxidation in overweight individuals more than GTE or placebo. It is further hypothesised that such improvements in fat oxidation due to GTE will lead to improvements in both body composition variables and submaximal exercise performance (metabolic efficiency) in overweight, but otherwise healthy persons.
The purpose of this study is to assess the effect of a food-specific Go/No-Go (GNG) computerized training task on weight loss, food evaluation, and disinhibition in a population of overweight and obese individuals.
Individuals who are overweight/obese are more vulnerable to type 2 diabetes (T2D). Current evidence suggests that PA, even without dietary prescription, can be efficacious in preventing T2D. Yet most Americans, especially those who are overweight/obese, are not physically active. Socioenvironmental barriers to physical activity (PA) such as body image concerns and limited access to fitness facilities contribute to the low levels of PA observed in overweight/obese adults. Web-based PA programs have been developed to address these barriers, but the outcomes have been marginal. Qualitative studies suggest that individuals who are overweight/obese prefer PA programs that feature people they can relate to especially in body size, fitness status and age. Previously, the investigators have included these preferences in a technology-based Physical Activity for The Heart (PATH) intervention that leverages open source platforms, such as YouTube, to promote PA in any setting. In this application, the investigators propose to test the feasibility and preliminary efficacy of PATH in promoting PA and reducing cardiometabolic risk in adults who are overweight/obese and at high risk of diabetes. In Aim 1 the investigators will conduct a 12-week randomized clinical trial including 52 adults who are overweight/obese and at high risk of diabetes to assess the feasibility and acceptability of PATH. In Aim 2 investigators will examine the trend in PA and cardiometabolic risk change from baseline to post-intervention. This approach is innovative because it leverages open source technologies to provide low-cost, action-oriented PA resources that match the preferences of adults who are overweight/obese. This contribution will be significant because PATH could offer a convenient, enjoyable and scalable program that features "similar others" to promote PA in overweight/obese adults at high risk of diabetes.
Evaluate the effect of Synbiotic 365 (Version 5 and 7) on body composition in overweight and obese individuals as measured by change in body mass index (BMI) and the percentage of body fat from Day 0 to Day 84 when compared to placebo by Dual Energy X-ray Absorptiometry scan (DEXA) for body composition (Body Mass Index, Lean Body Mass, Body Fat, Fat Free Mass).
The purpose of this study is to evaluate whether the Noom Healthy Weight Program, a digital behavior change weight loss intervention, creates a positive relationship with food, compared to a waitlist control group.
The purpose of this study is to investigate dietary compositions effect on liverfat measured by magnetic resonance imaging.
This research will constitute a 3-year follow-up that includes a re-evaluation and re-intervention of overweight or obese adults suffering from hypertension, who already participated in a similar programme with the same objectives 3 years ago. Patients will be recruited in the Hypertension Unit of a public hospital and assigned to a experimental group. The evaluation will include: eating behaviour, body mass index (BMI) and physical activity levels.
A randomized controlled trial for which the primary objective is to evaluate the effects of an online training program on physiotherapist's self-reported confidence in knowledge about weight management for people with osteoarthritis. 80 physiotherapists will be recruited into the study and randomized to one of two arms a) online training program (access to training program for 6 weeks) or b) control group (no access to online training program during the study). Questionnaires will be completed by all participants at baseline, and again at the end of the 6 week intervention period. A biostatistician will analyse blinded, de-identified data.
