Filter by:The epidemic of overweight and obese patients presents a major challenge in chronic disease prevention and overall health across the world. Since the beginning of this century, it is considered the third most important hazard attributable to burden of disease with approximately 350 million obese people (BMI ≥30.0) and over 1 billion overweight people (BMI ≥ 25) in the world. Mechanistic studies have indicated that the microbiota influences energy utilization from the diet and influences host genes that regulate energy expenditure and storage. Thus, it is proposed that alterations in gut microbiota may play a significant role in weight loss potential. This study seeks to expand on this idea by evaluating whether the incorporation of Rifaximin in an intermittent fasting (IF) diet plays a significant role in weight loss. Rifaximin is a nonsystemic antibiotic that works primarily in the gut to inhibit bacterial growth. It portrays unique eubiotic properties that induces a positive modulation of gut microbiota, favoring the growth of bacteria beneficial to the host without altering overall composition. Thus we propose an agent such as rifaximin would be essential in developing a positively altered gut microbiome. Based on studies evaluating Rifaximin's role in positive gut modification, we propose that this can play a critical role in weight loss. Rifaximin may be associated with weight loss as it exerts effects that increases the concentration of bacteria more prominent in lean individuals. The choice of incorporating an intermittent fasting (IF) diet, stems from its success in prior studies. By incorporating periods of voluntary abstinence from food and drink, an IF diet has shown short term weight loss among overweight and obese people. We propose that an IF diet with an antibiotic, like Rifaximin, will create more positive alteration in gut microbiota that creates a greater potential for weight loss overall. A group of subjects with BMI's ranging from 30-35 will be randomly selected and assigned to an experimental and control group. Each subject will be given clear instructions on how to follow a 14:10 intermittent fasting diet, in which they will fast for 14 hours and be able to eat for 10 hours a day. Patients in the experiment group will additionally receive a short-term low dosage of Rifaximin at the start of their diet. Patients will be evaluated with weekly weigh-ins and basic blood work performed at the start and at the completion of the study. The current hypothesis does not incorporate microbiome evaluation due to cost of the kits and limited funding available for the study.
Wholehearted living touches every aspect of life, from eating nourishing foods, to enjoying enough physical activity, to cultivating relationships that support healthy choices, to joining with neighbors to stand up for positive changes, and more. Unfortunately, for many low-income Californians, the idea of wholehearted living is an aspiration and not a reality. Koa Family: Strong, Healthy, Whole is an approach designed to make wholehearted living available for all. The Approach Koa Family is a 4-month journey to establish "micro-communities" of women supporting one another- mind, body, and spirit. The foundation of this approach is a new, custom-designed, online Whole Health Program (WHP) that addresses healthy eating, physical activity, and weight management within the context of wholehearted living. Low-income women and a lifestyle coach will meet weekly in a virtual platform to learn, experience, grow, and thrive as they reach their diet, physical activity, and weight management goals. Participants in the WHP will receive additional encouragement and access to local resources through a private and secure Facebook group. The group will provide a place for women to continue their wholehearted health journeys beyond the weekly meetings. Koa Family participants also will be invited to take part in a neighborhood tree planting campaign to create real, long-lasting, healthy changes to the environment in which they live. The Study Koa Family, with WHP at its core, is the product of extensive formative research both nationally and within low-income California communities. Koa Family will be introduced in Sacramento County in February 2021. It will be evaluated for effectiveness among 120 low-income, Supplemental Nutrition Assistance Program (SNAP)-Ed eligible women using a randomized controlled trial study design, the gold standard for assessing effectiveness of an intervention. Outcomes include changes in Body Mass Index, diet, and physical activity measured at 4 and 6 months from baseline. An economic analysis will assess the cost-effectiveness of Koa Family, while qualitative methods will identify mediating factors related to the study outcomes. Funding Koa Family is a project of the Population Health Group at the University of California, Davis, Center for Healthcare Policy and Research. Funding is provided by the United States Department of Agriculture Supplemental Nutrition Assistance Program-Education and the California Department of Forestry and Fire Protection (CalFIRE).
This was a study of tirzepatide in participants with obesity or overweight. The main purpose was to learn more about how tirzepatide maintained body weight loss. The study had two phases: a lead-in phase in which all participants took tirzepatide and a treatment phase in which participants either continued tirzepatide or switched to placebo. The study lasted about 2 years (25 visits).
The COVID-19 pandemic has created fear, financial difficulties and interruptions in the lives of patients and healthcare providers. As a result, many patients suffering from chronic conditions such as obesity have had their treatment disrupted by the pandemic. The Bariatric Medical Weight Management Clinic at St. Joseph's Healthcare Hamilton transitioned its weight loss and maintenance counselling classes to a remote (online) platform in response to the pandemic. The remote weight loss and maintenance classes allows patients to continue receiving treatment for obesity from their homes. The remote weight loss and maintenance program is conducted on a safe platform that has been thoroughly reviewed and approved by St. Joseph's Privacy Committees. The aim of this study is to learn whether the remote weight loss and maintenance classes can lead to similar weight loss compared to the in-person weight loss and maintenance classes that were offered to patients before the COVID-19 pandemic. This study also aims to gather feedback about the program to improve its delivery and patients' experiences.
Over 70% of Americans are either overweight or obese, putting them at risk for many chronic diseases including diabetes. Exercise is commonly used as a weight loss and weight loss maintenance strategy. However, exercise-induced weight loss is often much less than expected as individuals compensate for a large portion of the energy expended through exercise, resisting maintenance of the negative energy balance needed for weight loss. Our prior research, in agreement with others, point to increases in energy intake as the primary compensatory response when exercising for weight loss; however, mechanisms promoting this behavior have yet to be fully elucidated. With obesity and diabetes prevalence continually rising, innovative research is needed to identify novel mechanisms promoting energy compensation with exercise. The long-term goal of this proposal is to reduce the incidence and improve the outcomes of obesity-related diseases by developing interventions that will attenuate compensation for the energy expended through exercise and thus improve initial weight loss and weight loss maintenance. The present proposal will take the necessary first steps towards our long-term goal by identifying novel mechanisms promoting energy intake when exercising for weight loss. One's reinforcing value of food, attentional bias and inhibitory control for food cues play an important role in feeding behaviors, independent of hunger. These behaviors are largely a product of the central dopamine reward system, which is also in play with exercise behavior. This provides mechanistic support for our central hypothesis, that exercise evokes increases in food reinforcement, attentional bias, and lowers inhibitory control for food cues to promote greater energy intake in effort to maintain energy homeostasis. The rationale for this project is by elucidating the mechanisms mediating energy compensation, future interventions can be designed that attenuate this response to improve the utility of exercise as a weight loss intervention to prevent and manage T2DM. The overall objective of the current proposal is to demonstrate an acute bout of exercise alters food reinforcement, attentional bias and inhibitory control for food cues. Upon completion, we will have a greater understanding of the mechanisms underpinning compensatory increases in energy intake when exercising. These findings will pave the way for future clinical trials testing this hypothesis in the context of a long-term exercise intervention. This contribution is significant, as the identification of novel mechanisms influencing energy compensation with exercise is needed to provide strong support for the development of novel, evidence-based interventions to attenuate this compensatory response to exercise, improving its efficacy for weight control and chronic disease management.
The present study is a retrospective cohort study. Patients older than 18 years of age and underwent Roux-en-Y gastric bypass (RYGB) surgical treatment during the period from 2014 to 2019 and paired severely overweight controls who had no longer gone through bariatric surgery. Patients having BMI (Body Mass Index) much lower than 35 (calculated as the weight (kilograms) / length2 (meters)), a base line diagnosis taken into consideration a medical exclusion for surgical treatment died in one year of surgical operation and missed statistics at scientific information had been excluded from the study. The primary final results of the study was the weight-change percentage at follow-up in comparison with baseline one and the clinical events after surgery.
This lifestyle behavior intervention aims to weight loss in low-income overweight or obese mothers of young children through promotion of stress management, healthy eating, and physical activity. All eligible women will be assigned to the intervention group. The intervention will last 3 weeks and will be delivered via weekly web and individual health coaching sessions.
People often choose certain diets to lose weight or to change their habits or lifestyle. The Dukan diet was created in the '70s and took on importance in the last decade. It is a 4 phase diet similar to the Atkins diet. However, this diet is aggressive in its first phase because it suppresses carbohydrates, the main source of external energy being saturated low-fat protein. Studies of this diet are scarce and have been limited to describing the contribution of micronutrients. In nutritional practice, it is often assumed that a popular high-protein or low-calorie ketogenic diet could cause rapid or unfavourable changes in a patient's weight and body composition. However, the effect of these diets in the short or long term on weight and on body fat, muscle mass and other components is not clear. This means that body composition has not been the main objective when analyzing the effect of a popular diet. For this reason, the meta-analyzes focus on weight change and the absence of body composition data is a limitation of the selected studies. Changes in body composition due to a popular diet should be evaluated with techniques such as DXA. The aim of this study is to analyze the effect of a low-carbohydrate, high-protein diet with energy restriction on weight and body composition using DXA. For this, a randomized controlled study will be used where a group will receive the diet protocol. The control group will have a normal diet, and only one oatmeal drink will be added (55 g of oats in 250 ml of water). The drink will contain 1.6 g of BetaG per serving according to FDA recommendations that correspond to the 50% BetaG required per day.
To evaluate the effect of one-on-one coaching in the Noom Healthy Weight Program, a digital behavior change, weight loss intervention, compared to the same program with no coaching, as well as influential factors.
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.
