Active clinical trials for "Weight Loss"

This study will compare the safety and effectiveness of three popular weight loss plans. These plans will be compared with the USDA Dietary Guidelines.

This study will evaluate whether a program of weight loss and exercise can help individuals with knee osteoarthritis (OA).

This study tests the effects of emphasizing different motivations for wanting to lose weight on weight loss maintenance in women. At the start of the study, participants will be weighed and will complete questionnaires about their health, weight history, eating and exercise habits, body satisfaction and mood. Participants will then be randomly assigned to 1 of 4 treatments. Participants in all 4 groups will receive information on topics related to eating and exercise, and will receive calorie and fat intake goals, and exercise goals. The 4 treatments will differ in the emphasis given to various reasons for wanting to lose weight. At 6, 12 and 18 months after enrollment, participants will again have weights measured and fill out questionnaires.

To evaluate the safety, antiviral and anti-TNF-alpha activity, and preliminary efficacy of thalidomide in reducing weight loss in patients with HIV wasting syndrome.

The purpose of this study is to see if giving nandrolone decanoate (a hormonal drug) will cause weight gain in HIV-positive women who have HIV-associated weight loss (wasting). Wasting has become an AIDS-defining condition. In the past, most studies that examined wasting treatments were limited to men. However, it appears that wasting in HIV-positive men is linked to levels of testosterone (a hormone which affects men's bodies more than women's). This study has been designed for women only, in order to best treat wasting in HIV-positive women.

The major aim of the proposed study is to develop a gender-sensitive individually tailored add-on intervention that focusses on improving individual gender-specific SIRs (subjective illness representations) in obese or overweight individuals. We will investigate whether this will improve compliance with and long-term success of common weight loss interventions. The effectiveness of this intervention in every-day-life with regard to weight-related behavioral changes and weight loss will be evaluated within a randomized controlled setting.To enhance the applicability of the intervention in every-day-life and its dissemination we plan to develop a smart-phone-based intervention.

Very low-carbohydrate ketogenic diet may have beneficial metabolic and weight loss effects, however, adhering to this diet may be challenging. Keyto is a self-monitoring and app-enhanced intervention to help individuals learn about and monitor their breath acetone (a measure of ketosis) levels to promote dietary change and weight loss. The purpose of this research is to test the Keyto self-monitoring + app intervention against a "standard of care" weight loss dietary app (Weight Watchers). 144 participants will be recruited through Facebook ads, provide online consent, and will be randomized to one of the two conditions. Weight loss after 12 weeks will be assessed as the primary outcome, with weight loss at 24 and 48 weeks being secondary outcomes. Blood samples will be collected at baseline and 12 weeks with optional blood samples at 48 weeks follow up.

Weight regain after Laparoscopic Sleeve Gastrectomy (LSG) is nowadays a growing concern. Sleeve dilatation and loss of food restriction is considered the main mechanism. The placement of a silicon ring around the gastric tube seems to give benefits in the short-term. The Investigators evaluate the efficacy of banded sleeve gastrectomy compared to standard sleeve in the mid-term. Fifty patients were randomized between LSG and Laparoscopic Banded Sleeve Gastrectomy (LBSG), and they underwent a mean follow-up of 4 years. Patients' management was exactly the same, apart from the band placement. After surgery differences in weight loss, operative time, complication rate and mortality were analyzed.

Obesity is the main risk factor for Obstructive Sleep Apnea (OSA). Nasal CPAP is the standard treatment for OSA, but since weight-loss programs are not usually offered to OSA patients, the root causes of their illness and its comorbidities are not treated. There is some evidence regarding improvements in OSA after weight reduction but whether weight reduction programs are cost-efficient has not as yet been addressed. OBJECTIVE: To determine whether an intensive weight-loss program, carried out in a project combining hospital and primary care levels, is cost-effective in the medium and long term for the treatment of obese patients with severe OSA undergoing CPAP treatment. More concretely, our objective is to demonstrate whether this program achieves sufficient improvement in OSA to allow a reduction <30/h in the apnea-hypopnea index in at least 25%, improving their metabolic profile and central obesity. METHOD: A prospective, randomized, controlled study. Control group: standard dietary recommendations. Intervention group: 0-3 months very low calorie diet, 15 days substituting three meals for low calorie shakes, from 15 to 120 days substituting 1 meal and from 120 days to 12 months on a low calorie diet while starting a progressive exercise program. Recommendations for good sleep habits will be given. The program will be carried out through group and individual sessions with the hospital dietician. After 3 months: group sessions with a nurse in the basic area. Group sessions led by hospital dietician. From 3 to 12 months: group sessions led by primary care nurse. MEASUREMENTS: At the beginning, at 3 and at 12 months: two-night home respiratory polygraph, actigraphy, anthropometric and blood analysis data including metabolic syndrome and inflammatory markers, and health related quality of life questionnaires. Direct and indirect costs of treatments, outpatient's consultations, incomes, emergency visits and patients' travel costs to medical centers.

The purpose of the study is to evaluate the effect on weight loss in a group of subjects suffering from overweight and mild obesity (BMI between 25 and 32 Kg/m2) and with weight > 75 Kg/m2 being administered with a 3 g/day polyglucosamine dosage.
