Filter by:The purpose of this pilot study is to assess the feasibility of a double-blind, randomized placebo-controlled trial of semaglutide 2.4 mg subcutaneously once weekly on top of standard care compared to standard care alone.
The objective of this single-blind, parallel-arm, randomized clinical trial is to evaluate changes in body weight and composition, assess determinants of energy balance, and measure modulators of energy intake and expenditure, following 8 wk of calorie restriction (CR, -500 kcal/d) in combination with either overnight exposure (8 h/night) to normobaric hypoxia (NH; 15% oxygen, ~8500 ft elevation) or normoxia (NN; 21% oxygen, sea level), using a commercially available, in-home tent system, in adults who are overweight or obese.
Rationale: Older adults spend the majority of their time in sedentary behaviours (SB). High amounts of SB have been correlated with reduced cognitive performance. Long periods of time spent sitting results in excessive glycemic variability, potentially contributing to cognitive decline. Reducing/replacing SB with short intermittent bouts of light physical activity have shown positive effects on glycemic variability. Thus, interrupting prolonged sitting with bouts of light physical activity may regulate blood glucose and thus mitigate cognitive decline. Purpose: This study intends to investigate the appropriate interval frequency of post-prandial SB reduction, by light physical activity needed to optimize total and incremental area under the curve for glucose response in overweight older adults at risk for glucose intolerance with mild cognitive impairment in both lab and free-living environments. Second, this study aims to investigate the acute impact of reducing SB on glycemic variability and its relationship with cognition. Hypothesis: First, there will be a dose-dependent response of more frequent interruptions of SB (more frequent intervals of light physical activity) with better glycemic control. Second, reducing SB will result in less glycemic variability, which will translate into better levels of cognitive performance. Methods: Generalized linear mixed models with random intercepts will be used to evaluate the differential effects of the experimental conditions on the selected outcomes.
This study determines whether different forms of ketones supplemented prior to a meal lower the triglyceride (fat) content in the blood of overweight and obese individuals. Through a randomized crossover design, participants (n=15) will participate in each of the following three experimental groups (no treatment control, ketone ester, ketone salt), with a 5-14 day washout period between each experimental visit.
The purpose of this study is to test two versions a weight loss program potentially suitable for implementation in Africa. A successful method would have widespread application in low-income countries, with the potential to improve world health.
The purpose of this study is to determine whether robotic assistance can help facilitate adherence, engagement, and weight loss in participants enrolled in a behavioral weight loss program. All participants will be enrolled in the same Web-based weight loss program and take part in "robotic assistance sessions" either early or late in the five-week study. These robotic assistance sessions involve speaking one on one with a robot about diet-related progress.
