Active clinical trials for "Body Weight Changes"

The DIETAPYR2 study is a randomized controlled crossover trial consisting of two experimental periods each lasting 8 weeks. Enrolled participants were randomly assigned to either a Pyrenean beef-based diet or a conventional chicken-based diet and instructed to consume this meat three times a week. In the first visit the medical history was obtained and anthropometric measurements, blood pressure (systolic and diastolic) and heart rate were taken. The day after the first visit, in the morning, a sample of blood, stool and urine was taken from the participants after an overnight fast. At the time of this visit (period 1), each participant was randomly assigned to a Pyrenean beef diet (intervention group) or a conventional chicken-based diet (control group). After an experimental period of 8 weeks, the participants were invited to carry out the same evaluations as during the first visit. Subsequently, a 5-week washout period was carried out to eliminate the possible residual effects of the first experimental period. After the washout period, the participants were called back for the same assessments during a third visit just before the second experimental period (period 2). During this period, those who were previously on a Pyrenean beef diet (intervention group) were crossed with the conventional chicken diet (control group) and vice versa. Finally, after the second 8-week experimental period, the participants were retested as on previous visits.

Randomized cross-over design with 10 male subjects and 3 campaigns to test whether the negative effects of bed rest (6º head-down tilt) on the various systems of the body and the consequences to health of simulated weightlessness can be counteracted by the use of a defined training programme.

RATIONALE: Eating a diet that is low in antioxidants may control cachexia in patients with oropharyngeal cancer. PURPOSE: This randomized phase I trial is studying the side effects of a low antioxidant diet in controlling cachexia in patients with oropharyngeal cancer receiving chemotherapy and radiation therapy.

RATIONALE: Exercise and dietary counseling may affect weight loss and improve the quality of life of obese endometrial cancer patients and may help them live longer and more comfortably. PURPOSE: This randomized clinical trial is studying the effects of exercise and dietary counseling on weight loss and quality of life of obese patients with stage I or stage II endometrial cancer in remission.

Mainly due to the absence of gravitational forces in weightlessness, astronauts suffer from an increased bone loss- negatively affecting health and vitality during a mission. The development of effective countermeasures to this loss includes many different aspects like sports but also nutrition. Alkaline salts, abundant in fruits and vegetables, have shown to have positive effects on markers of bone turnover of postmenopausal women but also men and younger adults. With the current study the effects of a potassium bicarbonate supplementation added to a standardised, strictly controlled, definite diet of healthy, young men, should be verified within 21 days of 6°- HDT- Bedrest- the gold standard of simulating weightlessness within earthbound conditions.

RATIONALE: Physical activity, diet, and counseling may help breast and colorectal cancer survivors to lose weight and improve their quality of life. PURPOSE: This phase II trial studies how well exercise, diet, and counseling work in improving physical activity and weight loss in overweight women who are breast and colorectal cancer survivors.

The purpose of this study is to compare an technology-based weight maintenance intervention using action plans, videos discussion boards and health behavior tracking (weight, calories in and out, pedometer steps) with a technology-based standard advice group to facilitate health management, resourcefulness and health status for rural middle-aged women.

Although weight loss programs are effective in the short-term, maintaining weight loss is more challenging. Regularly tracking and logging physical activity (PA) and diet is related to greater improvements in PA and diet and to greater weight loss over time. Receiving continuous real-time feedback regarding calories burned and calories consumed could enhance weight loss maintenance. This study will examine whether a device that provides such feedback, called the SenseWear armband, enhances weight maintenance. 200 overweight adults aged 18 to 65 years will be randomly assigned to one of four groups: (1) a standard behavior change weight loss group-based program (14 group sessions over a 4 month period followed by 6 phone calls over a 5 month period), (2) a standard behavior change weight loss group-based program (15 group session over a 4 month period followed by 6 phone calls over a 5 month period) combined with the armband, (3) the armband alone (training in the use of the armband and a follow up telephone call), or (4) a self-directed weight loss control group. Participants will be recruited through USC through listserv emails, flyers, and worksite advertisements. Interested individuals will take part in a telephone screen, an orientation, a run-in visit (which includes 2 weeks of PA and dietary logging), a baseline assessment, and a randomization visit. The intervention will then take place over a 9-month period with eligible participants. Participants will take part in follow-up assessments at month 4 and 9. Assessments at all three times will include questionnaires assessing diet, PA, psychosocial factors related to diet and PA, and quality of life related measures. They will also have their fasting blood drawn to assess lipids, glucose, and insulin, and staff will measure their blood pressure, waist circumference (size), skinfold, height, and weight.

The purpose of this study is to compare the effectiveness of text message-based support to usual care at promoting weight loss in patients with pre-diabetes.

Tuberculosis (TB) patients often have a lower body mass index (BMI) and experience wasting. Wasting reduces lean body mass and may cause physical function impairment. This study aimed to determine the efficacy of fermented soybeans (tempeh) as a food supplement on body weight and physical function changes among active pulmonary tuberculosis patients with standard therapy.
