Active clinical trials for "Weight Loss"

Participants in both the existing and enhanced podcast groups will lose weight. The enhanced podcasting group will have a greater increase in weight loss, elaboration, self-efficacy, and perceived control than the existing podcast group.

The purpose of this study is to determine the effect of weight loss and exercise on liver and muscle fat.

Obesity is increasingly common and can lead to decreased quality of life, increased medical and psychiatric illness, high health care costs, and early mortality. The problem of obesity is as great in veterans as it is in the general public. Adherence to dietary therapy for obesity is often inadequate, possibly because patients' food preferences are not considered during dietary counseling. Allowing patients to choose a diet based on their food preferences may increase their motivation to adhere to diet counseling. This, in turn, could enhance their weight loss success and, ultimately, reduce the many health complications and costs of obesity. The proposed study will examine whether assessing a person's food preferences, and then allowing the person to choose from two commonly prescribed diets, results in greater weight loss success.

Overweight and obesity play a role in both cancer incidence and survival rates. Many people have found attending weight loss support groups to be time-intensive. Past research has shown electronic media, particularly the Web, to be effective in producing weight loss. The Web, however, lacks portability, which prevents people from accessing the information when it is convenient for them. Providing weight loss information via podcasting (audio files that may be listened to on portable audio players) may allow people to receive weight loss tips anywhere. A previous research study showed that podcasts emphasizing healthy eating and exercise can help people lose weight. This study was short-term and did not include additional social support. The purpose of this research project is to assess the effectiveness of a weight loss intervention delivered through podcasts as compared to the same podcast with added mobile media such as self-monitoring software (such as a pedometer) and support delivered via a social networking site. For this research study, the investigators will conduct a 6-month study in 104 overweight adults to determine if a podcast plus mobile media support leads to greater weight loss than a podcast alone.

Obesity and osteoarthritis (OA) co-exist in an increasing part of the population. The two diseases intertwine in several ways. The evolution in the population shows a tendency towards deterioration of both by increasing general age and weight. The two diseases share pathogenetic features and the development of one disease increases the risk of the other and may be the onset of a vicious circle. There is a link between treatments of these two diseases as well. There is now solid (gold) evidence that by treating effectively the obesity of patients with co-occurring OA, the functional status is dramatically ameliorated; the short-term results are equal to that of a joint replacement. The long-term efficacy of a weight loss remains to be shown. OA is definitely one of many diseases in which obesity must be taken seriously into account when planning a correct treatment of patients. This trial has two phases, the first (16 weeks) consisting of a dietary intervention with low-energy diet and the second (52 weeks) a randomized, three group (each n>50 patients) controlled study of maintenance of weight loss by either continuing dietary instruction, exercise, or a control group. The hypothesis is that maintenance of an initially induced weight loss is dependent on attention rather than any specific therapy.

The purpose of the study is to determine whether using a web-based weight loss website can help overweight individuals lose weight.

The goal of this project is to test whether a phone and mail-based program designed to help people who have recently lost weight helps them keep the weight off over a 2 year period.

The goal of this clinical research study is to find the highest tolerable dose of the drug Olanzapine that can be given to patients with advanced cancer who are experiencing weight loss. Researchers want to find out if Olanzapine can help decrease weight loss in patients who are experiencing it because of cancer. How this drug affects performance status, cancer-related symptoms, and nutritional status in patients with advanced cancer will also be studied.

The purpose of this study is to determine the effect of nasal PYY3-36 on weight loss post 24 weeks of treatment.

Behavioral weight loss, the current treatment of choice for moderate obesity, achieves impressive short term results, however, weight regain following treatment is a major problem. Over 50% of participants in behavioral weight loss programs report difficulty with internal antecedents to unhealthy weight control behaviors and this difficulty is associated with weight regain following treatment. Current treatment approaches do not adequately address these antecedents. The aim of this series of studies is to develop, implement, and evaluate a behavioral weight loss program modified to provide participants with skills to deal effectively with affective and cognitive difficulties. The study targets men and women with BMI of 27-40 who self-report difficulty with emotional and/or cognitive antecedents to unhealthy weight control behaviors. The study is an uncontrolled pilot study in 20 participants to initially assess acceptability and efficacy of the innovative treatment. The long-term goal of this research is to improve the weight loss maintenance outcomes of behavioral weight loss programs by addressing affective and cognitive antecedents to unhealthy weight control behaviors.
