Since overweight and obesity, a risk factor for various diseases, is a prevalent problem in the modern society, it is important to search for new strategies to counteract this. In contrast to in person support, the internet provides a low cost opportunity, which is able to reach a large part of the population. Therefore a web-based weight loss program may be an adequate mean for many people. Now it is hypothesised that a web-based weight loss program is able to support a reduction of body weight and weight-related cardiovascular risk factors effectively and to promote a healthier lifestyle. It is expected that program use, compared to a control group, results in greater reductions in body weight and cardiovascular risk.
Patients with overweight or obesity are in need to loose weight and represent a particularly challenging medical condition. Undoubtedly, any intervention achieving a negative energy balance over an extended time period will result in weight loss. Although several treatment modalities are available, currently the most extended approaches are lifestyle changes, pharmacotherapy, and bariatric surgery. Given the limited approved anti-obesity drugs, the main therapeutic strategies involve either conventional treatment or bariatric surgery. Conventional weight-reduction programs pursue a safe weight loss rate of 0,5-1,0 kg per week. The main modifiable factors affecting energy balance are dietary energy intake and energy expended through physical activity. In spite of the difficulty in achieving relevant and sustained weight loss via the conventional approach, some patients are successful in reducing weight and obesity-associated complications. Bariatric surgery has proved to be the most effective long-term treatment for weight loss and comorbidity improvement. While some of the surgery-induced benefits are directly dependent on adipose tissue reduction, others are due to specific gastrointestinal changes that take place early on and before any significant effects on body weight are observed. The present study contemplates the determination and comparison of the anthropometric and metabolic changes produced by the conventional and surgery-induced treatment modalities. Particular emphasis will be placed on the potential differential effects between conventional and surgical weight loss on body composition changes, circulating adipokines and gastrointestinal hormones together with their subsequent impact on cardiometabolic risk factors.
The purpose of this study is to find out if there is any change in diet on food cravings and weight loss in the 12 months following bariatric surgery.
Primary objective: This is a preliminary study to determine if Mirtazapine in comparison to placebo will improve appetite in advanced cancer patients with anorexia and weight loss. An improvement of appetite is defined as a decrease of 2 in the appetite score from baseline on the Edmonton Symptom Assessment Scale (ESAS) at day 15 (+/-3 days). Secondary objective-A: To determine if Mirtazapine in comparison to placebo will improve insomnia ( as measured by Pittsburgh Sleep Quality Index) on day 15 ( +/- 3 days), and day 29 ( +/- 3 days) Secondary objective - B: To determine if Mirtazapine in comparison to placebo will improve other common symptoms such as pain, nausea and fatigue( as measured by ESAS), depression and anxiety ( as measured by Hospital Anxiety and Depression scale), and quality of life ( as measured by Functional Assessment of Anorexia/Cachexia Therapy ) in advanced cancer patients with anorexia/cachexia, on days 15 (+/-3 days), and 29 (+/-3 days) Other Objectives: To provide exploratory data on the effects of Mirtazapine on weight gain, and preservation/gain lean muscle mass ( anthropometric measurements and Bioelectric Impedance), on days 15 (+/-3 days), and 29 (+/-3 days). To provide exploratory data on the effects of a Mirtazapine dose increase to 30 mg on decreased side effects of drug and increased appetite on day 29 (+/-3 days).
The Metabolic Syndrome (MS) is prevalent in the American population and is strongly associated with premature coronary disease. Lifestyle intervention, primarily exercise and dietary changes, are foundational treatment strategies for independent components of MS, but these interventions have not been thoroughly evaluated in MS. Even with very modest weight loss, in the setting of caloric restriction and exercise, marked improvement MS parameters have been noted. However, it is not known whether it is diet with weight loss or exercise that improves the metabolic derangements associated with MS. We propose a study designed to examine the relative impact of diet or exercise on the components of MS. Furthermore, it is known that psychological factors significantly impact the ability of patients to initiate and sustain lifestyle changes. We will monitor certain psychological states to evaluate their impact on the success of weight loss and sustainability of lifestyle changes throughout this study. Specific Aims: 1.) Evaluate the relative efficacy of diet with weight loss or exercise on improving the markers of metabolic syndrome. 2.) Determine of pre-existing psychological factors influence the effectiveness of diet with weight loss or exercise on the markers of metabolic syndrome. Design: Adult women (> 18 yrs) with a body-mass index (BMI) 30 kg/m2 will be assessed for MS and randomized to one of three groups (n = 34/group), Control (C), diet with weight loss alone (D), or exercise alone (E). The intervention groups will participate in supervised dietary changes designed for weight loss or exercise for 6 months. Anthropomorphic, serologic, and psychological parameters will be monitored and compared using ANOVA. Hypothesis: As indexed by the improvement in the laboratory markers of the components of metabolic syndrome, exercise alone has a more profound positive impact on Metabolic Syndrome then diet with weight loss alone.
