Filter by:MapTrek is a mobile-phone-based web app that allows participants to take a virtual walk in interesting locations around the world while tracking their progress against the progress of other veterans on an interactive map. Steps are counted using a commercially available triaxial accelerometer (e.g. Fitbit), and users see their own updated progress overlaid on Google Maps, with Google Maps features (e.g. zooming, street view, etc.) available. The objective is to report activity levels in the virtual environment to veterans, thereby encouraging them first, to walk more every day, and second, to maintain these new increased levels of physical activity.
The objective of the present study is to evaluate the effect of a 20-week group intervention program based on acceptance and mindfulness in emotional eating, weight loss, physiological parameters and the level of physical exercise, as well as in the quality-of-life and weight self-stigma of overweight and obese people on the short- and medium-term. Design, participants, and method: A randomized clinical trial comprising a total of 110 overweight or obese (BMI ≥ 25) participants that are receiving medical treatment at Primary Care Centers, 20-65 years, will be included and randomly assigned to standard program (N=55) or standard + intervention program (N=55). The standard program group will receive the treatment as usual (TAU) that comprises 5 sessions (on a monthly basis) that will include a personalized diet and physical exercise recommendations, while the standard + intervention program group will receive the same TAU plus the acceptance and mindfulness-based group intervention program. At baseline prior to randomization, after the intervention, and seven months after the program has finished anthropometric and body composition data, biochemical data in blood, waist circumference, blood pressure, eating habits, level of physical exercise, general health, emotional eating, quality-of-life, weight self-stigma, experiential avoidance, self-compassion level and mindfulness abilities will be evaluated. It is hypothesized that the integrated treatment of obesity implementing a group intervention program based on acceptance and mindfulness could help to reduce the emotional eating, enhance weight loss, improve physiological parameters, increase the level of physical exercise, improve the quality of life and reduce the weight self-stigma of overweight and obese individuals.
Cardiometabolic disorders are a leading cause of death worldwide. Replacing saturated fatty acids (SFA) with unsaturated fatty acids is recommended as a way of lowering cardiometabolic disease risk. Consuming a diet rich in SFA may lead to a greater metabolic-inflammatory response in white adipose tissue during the fasting state, when compared to eating a diet rich in monounsaturated fatty acids (MUFA). Since individuals spend most of the day in the fed (or postprandial) state, it is important to see how different types of dietary fatty acids affect postprandial white adipose tissue and systemic metabolic-inflammatory responses. This study will investigate the effect of a SFA-rich meal on markers of white adipose tissue and systemic metabolic-inflammation, compared to a MUFA-rich meal in overweight adults. In a randomised, single blind controlled, cross-over manner participants will consume either a SFA- or MUFA-rich meal and sequential blood and white adipose tissue samples will be collected before and until 6 hours postprandially.
This is a study about how the price of foods affects food buying choices at the grocery store. The price of foods can have a big impact on what people choose to buy and prices change over time. This study is being done to see how changes in food prices affect what mothers choose for their families.
This trial studies how well weight bearing exercise works in preventing frailty in stage I-IIIA breast cancer survivors. Weight bearing exercise, including muscle-strengthening, aerobic, flexibility, and balance exercises, can decrease fat and increase muscle, which may lead to reduced frailty.
The study is looking at possible new medicines for weight control in people with high body weight. The study looks at how the new medicines work in the body. The study consists of two parts. If participants take part in Part 1, they will either get a single dose of NNC0165-1875 or a "dummy" medicine (placebo). If participants take part in Part 2, they will either get a single dose of NNC0165-1875 or "dummy" medicine and also a single dose of semaglutide. Which treatment participants get is decided by chance. For Part 1 participants will get 1 injection. For Part 2 participants will get 2 injections. A study nurse at the clinic will inject the medicine with a thin needle in a skin fold in the stomach. The study will last for about 9 weeks. Participants will have 7 visits to the clinic with the study doctor.
Obstructive sleep apnea (OSA) is characterized by a repeated partial or complete obstruction of the airway that results in a intermittent hypoxia and sleep disturbance. A complex and reciprocal link between obesity and OSA exists. On the one hand, obesity is one of the main risk factors for OSA. On the other hand, OSA seems to promote obesity. The changes in sleep patterns that characterize OSA alter energy metabolism and promote weight gain. In particular, OSA is associated with metabolic disturbances, decreased physical activity and changes in energy expenditure resulting in weight gain. OSA is characterized by resistance to leptin which reduces the feeling of satiety and an increase in ghrelin levels which increases the feeling of hunger. There may be an increase in food intake, but very few studies have looked at this aspect. Our current knowledge is based on simple patient reports of the amount of food consumed per 24 hours. First-line treatment of OSA is based on continuous positive airway pressure (CPAP) but this approach is not curative and weight loss is encouraged. CAPP could facilitate weight loss by restoring sleep quality. Paradoxically, recent studies show weight gain proportional to the duration of use of CPP. Randomized controlled trials offering apneic patients a return to physical activity and hygiene-dietary rules have shown an improvement in OSA after weight loss. A better understanding of the influence of OSA and its treatment on the energy balance through food preferences and olfacto-gustatory sensoriality is an essential prerequisite for personalized nutritional management. In the face of unexpected weight gain under CPP, this type of intervention would be all the more beneficial as OSA and obesity are public health problems representing two independent risk factors for cardiovascular morbidity and mortality with increasing incidence. We hypothesize that the treatment of OSA with CPAP changes food preferences in favour of fatty and sugary high-calorie foods.
American College of Cardiology/American Heart Association (ACC/AHA) hypertension guidelines recommend lifestyle modification for patients with elevated blood pressure. While eating a Dietary Approaches to Stop Hypertension (DASH)-type diet, increasing physical activity, and weight loss have been shown to reduce blood pressure, limited resources are available in the primary care setting to help patients make these changes. In this study, the investigators will compare the efficacy of a self-guided vs. dietitian-led approach using web-based lifestyle modification tools to reduce weight, improve dietary quality, and lower blood pressure in overweight/obese adults with elevated blood pressure.
This randomized, cross-over trial aims to assess changes in body weight, plasma lipids, insulin sensitivity, and postprandial metabolism with a low-fat, plant-based diet and a Mediterranean diet, both followed for 4 months.
By doing this study, researchers hope to learn about the feasibility of using a mobile application to help overweight or obese adults with PAD increase their walking distance and lose weight.
