Active clinical trials for "Weight Loss"

This is a dual site, prospective study which will compare plicated-Laparoscopic Adjustable Gastric Banding (PLAGB) to standard LABG (SLAGB) to identify significant differences in bariatric surgical outcomes Weight Loss Co-morbid disease resolution

The aim of this study is to examine the effects of combination of acupuncture and ayuveda yoga exercise on weight loss for the overweight.

This study aims to analyze the effectiveness of introducing behavioral elements in a weight loss program, in this case, comparing the difference between self-weighing versus not doing so.

The experimental participant group (n=15+15) includes male and female fitness athletes during their ~25 week competition preparation in fall 2019 for the Finnish national championships. Participants must have at least two years of goal-oriented gym training and their health status will be determined before measurements via an online pre-study questionnaire. The control group (n=15+15) will maintain their normal training and diet without competing during the study period. Otherwise, the control group is matched with the athletic group based on age, height, weight and training experience. Participants selected for the study will complete an additional questionnaire to be reviewed by the study physician to confirm that participants meet the health status inclusion criteria. This study includes four laboratory testing sessions over the 50-week period. Time points include testing before the diet or the control period start (PRE), one week before the competition (MID), after the competition (COMP) and after a recovery period (POST). During COMP-POST the participants are advised to continue training, but to stop competition dieting."Measurements will include body composition (fat mass and fat free mass by bioimpedance, DXA and skinfolds), resting metabolic rate (indirect calorimetry), vastus lateralis and triceps brachii muscle-cross sectional area, subcutaneous fat thickness from ultrasonography and circulating hormone analysis. Also, whole blood will be analyzed for hemoglobin and hematocrit and systems biology approach: e.g. serum metabolome and possibly also other analysis. Lower body maximal voluntary isometric force will be measured via knee extension machine device. Average weekly physical activity will be determined with a wrist-worn uni-axial accelerometer. Training and dietary data (nutrient intake, volume, intensity etc.) will be collected via nutrition and training diaries. Psychological questionnaires will be conducted via an online survey.

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 primary objective of this trial is to examine the weight-loss efficacy of Freshly Fit meals, as well as body composition, waist/hip circumference, metabolic markers, and quality of life in overweight and obese adults.

Obesity is a complex disease associate to metabolic alterations, which may lead to cardiometabolic risk in women with obesity. The use of interactive digital technology as adjuvante tool to the clinical practices in weight loss therapy emerges as an innovative strategy. However, it was note fully investigated if this kind of approach can contribute to improve inflammatory state and metabolic alterations in obese population.

The overall objective of this study is to investigate in depth the impact of birth weight on the nature of metabolic physiology, body composition and epigenetic differences of the different phenotypes of overweight and obese individuals who are otherwise overtly healthy. We also aim to determine the efficacy of a weight loss intervention on the above mentioned metabolic parameters in these individuals.

This double blind placebo study will take place over an 8 week treatment period of diet and exercise. All participants (n=16), in two groups, will be placed on the same hypocaloric diet and exercise program. Participants will be matched into pairs based on body fat % and then assigned into a test group & a placebo group. The placebo will be in the form of a powdered isoenergetic beverage with carbohydrate similar in taste & appearance to the powder BCAA supplement that the test group will receive. The test group will be put on 0.342g/kg of BCAA per day, partially accounted for through their diet with the rest provided by a BCAA supplement. At baseline, 4 weeks and 8 weeks habitual 3 day food logs, waist to hip ratio and BodPod measures of body fat & lean mass (both percentage & absolute values) will be taken for all participants.

Although obesity surgery is currently the most effective method for achieving weight loss, not all patients lose the desired amount of weight and some show weight regain. Previous pilot work by the lead researcher shows that successful weight loss is associated with the amount of investment the patient feels that they have made in their operation. For example, those who feel that it has taken more time and effort to organise, has cost more money, has been more disruptive to their family, social and work lives and has caused pain are more likely to lose weight after their operation. Therefore, it seems as if the greater the sense of investment, the greater the motivation to make the operation a success. The present study aims to build on these findings by encouraging weight loss surgery patients to focus on the investment they have made, thus making their investment more salient to them. Using a trial design, half the patients will be asked to rate and describe the investment they have made in their operation just before surgery (focusing on the time and effort to organise the surgery etc) and 3 months after surgery (focusing on time off work for recovery, disruption of family and friends, pain of surgery, pain of having the stitches removed etc). All patients will record their weight, beliefs about food, intentions to change their behaviour and actual eating and exercise behaviour at baseline then 3, 6 and 12 months follow up. The impact of the investment based intervention will then be assessed to explore whether focusing on the investment involved in having surgery improves patient health outcomes by one year.
