Filter by:This pilot study aims to recruit 30 adults with abdominal obesity, without major chronic disease, and test whether clinical dietary advice that is solely focused on the timing of eating (time restricted eating), has an effect on cardiometabolic health compared to standard dietary advice for cardiometabolic health, which is focused on content. The goal of this pilot study is to develop and hone dietary counseling approaches for time restricted eating for RD's in a clinical practice paradigm, and collect data on testing this intervention compared to standard dietary counseling approaches for cardiometabolic health.
Obesity is characterized by an underlying inflammatory state in which various inflammatory signaling molecules, termed cytokines, affect metabolic processes central to type 2 diabetes and cardiovascular disease; leading causes of disability and death in Ontario. Such obesity-associated inflammation is partly due to the movement of endotoxin (i.e. lipopolysaccharide (LPS), a cell wall component of Gram-negative bacteria) from the gut microbiota to the blood, resulting in elevated blood levels of LPS (a condition termed metabolic endotoxemia) that stimulates inflammation. Digestion of a high-fat meal increases blood LPS and is subsequently associated with inflammation and metabolic impairments. However, in this context, little is known about how the consumption of bioactive-rich foods, such as whole apples, can improve impaired inflammatory and metabolic responses in overweight and obese individuals. Apples are a key commodity to study given that they are Ontario's predominant fruit crop with the apple industry valued at approximately $400 million, they require little food preparation, and they are common in the diet year-round. There are some, but limited, reports of potential apple-induced health benefits related to reductions in inflammation and improved metabolic responses in lean/healthy individuals, but work in overweight and obese individuals is especially lacking. Thus, to address the gap in our understanding of how daily apple intake may improve the health consequences of obesity, we will conduct a randomized clinical trial in which overweight and obese adults will consume three Ontario-grown Gala apples (approximately 300 g) as part of their typical diet in one sitting (i.e. acute consumption) and/or daily for six weeks (i.e. chronic consumption). The Acute Apple Consumption phase of the study will follow a randomized crossover design in which participants' rate of gastric emptying, efficacy of dietary lipid digestion and absorption, and production of inflammatory cytokines and biomarkers of metabolism will be assessed before and after consuming a high-fat meal (designed to provide 1 g fat/kg body weight) with or without three apples in one sitting. The Chronic Apple Consumption phase of the study will follow a randomized, controlled, parallel-arm design in which participants' (fasting) production of inflammatory cytokines and biomarkers of metabolism, as well as their gut microbiota profile, will be assessed before and after consuming three apples (or no apples) daily for six weeks. We hypothesize that the consumption of three whole apples in one sitting and daily for six weeks will improve these parameters in overweight and obese individuals at risk of developing chronic metabolic diseases.
The objective of the proposed study is to enroll women with obesity that will undergo a controlled, energy restricted feeding intervention to test the effects of chronic ethanol consumption on adipose distribution and circulating testosterone during weight loss.
This is a large and comprehensively phenotyped cohort with fasting glycaemia where the predictive value of body composition and anthropometric measures of total and central fat distribution for postprandial carbohydrate intolerance are studied.
Given the increasing prevalence of obesity, there is an urgent need to find better strategies to promote physical activity in the community. The present study will invite 70-year-olds with central (abdominal) obesity to participate in a 10-week aerobic exercise program. Participants will be randomly assigned to one of two equally large groups. The first group will complete the exercise program in instructor-led groups. The second group will complete the program at home with the help of an on-line video.
Objective: To show metabolic and hormonal responses and effects on abdominal obesity of aerobic exercise in different intensity and duration and detraining period in women with metabolic syndrome.
The aim of this study was to compare the effects of three months' endurance training and three months' endurance-strength training on inflammatory markers in women with abdominal obesity.
The objective of this study is to assess feasibility of the application of an adapted version, with permission, of Dr. Cenk Tek's Simplified Intervention to Modify Physical activity, Lifestyle, and Eating behavior (SIMPLE Program), at Pathways to Housing in Calgary, Alberta. Dr. Tek and his colleagues reviewed the literature and eloquently summarized how individuals with severe mental illness, particularly schizophrenia and schizoaffective disorder are disproportionately affected by obesity and its cardio-metabolic sequelae leading to markedly reduced longevity and increased healthcare costs. Most new antipsychotic medications, which are credited for significant advances in patients' quality of life, appear to induce further weight gain, compounding the problem of obesity and related medical morbidity and mortality. In addition to the weight gain associated with psychiatric medications, sedentary life style, lack of availability of healthy food options, poverty, low level of physical activity, cigarette smoking, and inadequate knowledge or understanding of health maintenance, appear to contribute to the increased obesity rates and poor health in the severely mentally ill. Dr. Tek and colleagues reviewed the available literature on weight loss interventions in individuals with severe mental illness. Despite the overwhelming problems related to obesity, Dr. Tek's team found that research on obesity interventions for persons with schizophrenia is relatively neglected and that there were no treatments that were convincingly shown to be effective for weight reduction in this population with unique needs. Sensing a major societal gap, they decided to create their own weight loss intervention specifically for individuals with severe mental illness. Toward this aim, they collaborated with Dr. Kelly Brownell who created the Lifestyle, Exercise, Attitudes, Relationships, and Nutrition or LEARN Program. This multi-faceted program is designed to promote positive changes in motivation, attitude and deeply ingrained habits that will lead to long lasting weight loss. Brownell's LEARN program is a self-directed weight loss program that empowers the user to make lifestyle changes. Dr. Tek and his colleagues modified and built upon the program by creating the Simplified Intervention to Modify Physical activity, Lifestyle, and Eating behavior or SIMPLE program specifically for individuals with severe mental illness (http://www.simpleprogram.org/). The SIMPLE program is a group weight loss intervention designed for obese patients with schizophrenia or schizoaffective disorder. Dr. Tek and his team piloted their modified weight loss program and published their findings in 2007. Their preliminary study yielded greater weight loss than any of the published randomized controlled trials for a chronic and stable schizophrenia sample, and was the only study to show continued weight loss after the intervention ended. These early results prompted a new larger randomized controlled trial with the largest sample studied to date, an extended period of follow-up, and more detailed testing of the effects of weight loss on schizophrenia symptoms, quality of life, and laboratory markers of obesity related illness risk over a period of up to 16 months. Preliminary results of this trial show significant, sustained weight loss. The goal of this study presented for ethics review, is to apply Dr. Tek's 16-week intervention to a small group of patients at the Pathways to Housing program in Calgary, Alberta. The study coordinator will use Dr. Tek's published manuals, giving full acknowledgment to the authors, to create weekly supportive educational sessions for the group of patients. Three Pathways to Housing staff members, who regularly create education groups for Pathways to Housing patients during a weekly "lifestyle group", will sit in on each session. Weight (to calculate BMI) and waist circumference will be measured weekly. There will be no control group. The proposed feasibility study is designed to fit seamlessly within existing frameworks at Pathways to Housing. Upon completion of the study, we will convene a debriefing session with both the participants and the three Pathways to Housing staff to learn whether patients found the intervention valuable, and whether staff members feel capable of implementing the program on their own going forward. If the program is found to be feasible, the materials created will be available for future use by the multidisciplinary team at Pathways to Housing.
Nonalcoholic fatty liver disease (NAFLD) is common in individuals with obesity and is a significant threat to public health, because it can lead to impaired liver function and liver failure. Growth hormone is a hormone produced in the pituitary gland that helps regulate metabolism and growth. Individuals with obesity, on average, secrete less growth hormone than individuals without obesity. There are data to suggest that growth hormone may help to reduce the amount of fat in the liver, and may also reduce inflammation in the liver, both of which would be helpful to individuals with NAFLD. The purpose of this study is to investigate whether treatment with a drug called tesamorelin, which is a growth hormone releasing hormone analogue, will decrease liver fat and improve liver inflammation and scarring in obese individuals with NAFLD.
The investigators propose to undertake a controlled dietary intervention study in UAE subjects with visceral obesity to examine the feasibility of a diet rich in fruits, vegetables and/or whole-grain fiber in the UAE population. The research will also investigate the longer-term influence of increased fruits, vegetables and fiber consumption on health and its capacity to sustain lifestyle change.
