Active clinical trials for "Overweight"

The purpose of this trial is to determine the most cost effective programme for overweight and obese individuals to maintain weight loss over a 2 year period.

This study will examine the health effects of calcium supplements in overweight adults. Overweight adults often eat a diet low in calcium. Some studies have found low calcium intake in people who have some of the medical problems often seen in overweight adults. This study will see if extra calcium improves the health of overweight adults. Volunteers in general good health 18 years of age or older who are overweight (body mass index equal to or greater than 25 kilograms per square meter of body surface) may be eligible for this study. Women who are pregnant or breastfeeding may not participate. The study includes four visits, described below. Visit 1 Volunteers will be screened for participation in the study with a medical history, physical examination, and blood and urine tests. At home, they will collect a 24-hour urine sample; fill out questionnaires to assess their average calcium intake; and record their food intake for 7 days. Those enrolled in the study will continue with the next 3 visits. Visit 2 Participants will complete a physical activity questionnaire, have their food diary reviewed, and meet with a dietitian for nutritional counseling. Triceps fold thickness and waist and hip circumferences will be measured three times. Body composition will be analyzed by a DEXA study. For this procedure, the subject lies on a flat table while a small dose of X-rays is passed through the body. Participants will be randomly assigned to take either calcium carbonate (1500 mg/day) or placebo capsules twice a day by mouth for 2 years. (The placebo looks like the calcium capsules but contains no calcium.) They will receive a 6-month supply of study capsules during visit 2 and return to NIH every 6 months for the next supply. They will also be sent questionnaires by mail every 3 months to complete information about health problems and how often the study capsules are being taken. Visits 3 and 4 Visit 3 is scheduled after participants have taken the study capsules for 1 year; visit 4 is scheduled after 2 years (the end of the study). At each of these visits, participants will have a DEXA scan, blood and urine tests, blood pressure measurements, and measurements of height, weight, waist and hip circumference. They will complete questionnaires about their medical history, side effects of the study medications, dietary calcium intake, and physical activity, and they will meet with one of the study investigators to talk about any concerns regarding the study. At the fourth visit, participants will answer some additional questions about their study participation and return the Diet History Questionnaire that was mailed to them before the visit.

the aim of the study was to investigate the effect of aerobic and resisted exercise program on lipid profile and quality of life in overweight breastfeeding women.

Metabolic and cardio-vascular complications can often appear in overweight and obese children from an early age. Currently, there are few studies in the specialized literature that correlate clinical, biological and ultrasound parameters in order to stratify cardio-metabolic risk in obese children. Also, the specialized literature is poor regarding longitudinal follow-up and the importance of diet for reducing metabolic and cardiovascular complications in these children. This study is designed to assess the hypothesis that the sustained improvement of lifestyle with regard to nutrition and exercise can reverse cardiometabolic multimorbidities in obese children as assessed by clinical, biological and ultrasound evaluation.

This study will investigate the feasibility of combining an app-based Mindfulness training (MT) with at-home administered transcranial direct current stimulation (tDCS) in adults with overweight or obesity and assess whether MT with tDCS may improve weight-related behaviours in this population. Specifically, the study will assess whether MT+ active tDCS, as opposed to MT+ sham tDCS or waiting list control, reduces high calorie food craving and consumption. Findings will inform the development of a future large-scale randomised controlled trial. The trial will be conducted in the UK.

This is a multiple dose study to evaluate the safety, tolerability, PK, and PD of K-757 and K-833 when co-administered in overweight/obese patients with Type 2 diabetes mellitus (T2DM).

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.

This study will look at the change in teenagers' body weight from the start to the end of the study. This is to compare the effect on body weight in teenagers taking semaglutide (a new medicine) and teenagers taking "dummy" medicine. The teenagers in the study and their parents will also have talks with study staff about healthy food choices, how to be more physically active and what they can do to help the teenagers lose weight. The teenagers will either get semaglutide or "dummy" medicine - which treatment is decided by chance. The teenagers will take 1 injection every week, on the same day of the week for about 15 months. The study medicine is injected with a thin needle in a skin fold in the stomach, thigh or upper arm. The teenagers will have 17 clinic visits, will have blood samples taken and will have to complete questionnaires and keep a diary. All this will be explained before study start.

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.

The planned period of each cohort is 22 weeks including subject screening, treatments for 12 weeks, and follow up period.
