Active clinical trials for "Weight Loss"

Many elderly experience weight loss and weakness with normal aging. Although there is extensive literature regarding nutritional advice for the elderly, there are few well- designed studies evaluating the effect of oral nutrition supplements in patients with weight loss and aging. The aim of this study is to examine the effect of dietary prescription with or without nutrition supplementation that includes soy protein, whey protein and fish oil in elderly patients who have suffered unintentional weight loss.

RATIONALE: Cyproheptadine hydrochloride may prevent weight loss caused by cancer or cancer treatment. It is not yet known whether cyproheptadine is more effective than a placebo in preventing weight loss in young patients receiving chemotherapy for cancer. PURPOSE: This randomized phase III trial is studying cyproheptadine hydrochloride to see how well it works in preventing weight loss in young patients receiving chemotherapy for cancer.

Purpose and objective: To identify in the early post-operative period following laparoscopic Roux-en-Y gastric bypass patients likely to fail to progressively lose weight in expected fashion, and to institute intervention and assess for its efficacy. Study activities and population group: Patients identified to have "poor weight loss" (≤ 11% of excess weight loss) at 1 month will be randomized into a control versus study group. Intervention for subjects randomized to the IV arm will be by enrollment in the Back on Track program. This is a seven-week group education, counseling, nutrition, exercise, and journaling program of the Duke Weight Loss Surgery Center designed to help postoperative bariatric surgery patients who are failing to progressively lose weight resume an expected pattern of weight loss and improved overall outcome. Data analysis and risk/safety: Data will be collected and analyzed by the identified investigators. The goal of data analysis is to uncover any difference in the EWL of subjects who underwent intervention for falling in the lowest EWL quartile when compared with those who did not undergo intervention, and determine the statistical significance of any such difference. There are no physical risks associated with this study. There is, however, the potential risk of loss of confidentiality. Every effort will be made to keep your information confidential.

This two-phase study aims to explore ways to predict who will respond well to the weight loss drug lorcaserin and to understand the mechanisms that develop which limit drug efficacy. Subjects will be recruited for a 5-week crossover study (phase 1) with lorcaserin and placebo followed by treatment with lorcaserin for 24 weeks (phase 2).

RATIONALE: Megestrol acetate may help improve appetite and lessen weight loss caused by cancer. PURPOSE: This clinical trial studies megestrol acetate in treating weight loss or anorexia in young patients with malignancies who are undergoing radiation therapy and/or chemotherapy.

RATIONALE: Cyproheptadine hydrochloride may help improve appetite and lessen weight loss caused by cancer or cancer treatment. It is not yet known whether cyproheptadine hydrochloride is more effective with or without nutritional supplementation in improving weight and quality of life of young patients with weight loss caused by cancer or cancer treatment. PURPOSE: This randomized phase II trial is studying cyproheptadine hydrochloride to see how well it works when given together with or without nutritional supplementation in treating young patients with weight loss caused by cancer or cancer treatment.

72 patients with head and neck cancer, undergoing primary treatment with radiation therapy and concomitant weekly cisplatin, will be recruited to this multicentre trial. Randomized 1:1 to either 12-week progressive resistance training (PRT) program or control arm, starting together with concomitant chemoradiotherapy (CCRT) Stratified by centre, gender, p16-status and body mass index (BMI) below or above 30. Primary endpoint is difference in change in lean body mass (LBM) between the groups and the endpoint is reduction of LBM loss in intervention arm by 25% compared to control. Secondary endpoints include side-effects to treatment, change in body composition, physical function and strength, and compliance to PRT. Questionnaires on QoL, diet, voluntary exercise and work affiliation will also be registered. Blood samples for explorative analyses will be drawn and optional muscle biopsies drawn for proteomics analyses and histological analyses.

The aim of this study is to examine the impact of lifestyle intervention on postpartum weight loss. So the investigators will have two groups in this study. In Experimental group women will receive the Healthy Lifestyle Intervention. This intervention will have been delivered during 12 weeks. In Control group women will receive general information via pamphlet about postpartum period and tips for stress management.

Intentional weight loss in obese, older adults remains controversial. Although caloric restriction, resulting in significant weight and fat mass loss, ameliorates many clinical consequences of obesity, recommendation of intentional weight loss in aging remains controversial. Reluctance stems, at least in part, from loss of lean and bone mass known to accompany overall weight loss and potential exacerbation of age-related risk of disability and fracture. Accordingly, current treatment guidelines call fhttp://google.wfu.edu/or weight-loss therapy that minimizes muscle and bone losses for older persons who are obese and who have functional impairments or medical complications that can benefit from weight loss. Amount of dietary protein consumed during caloric restriction may be a key determinant in maintaining fat-free mass during weight loss. Adequate dietary protein is essential for skeletal muscle anabolism; and, epidemiological evidence in older adults point to a salutary effect of protein intake above the current RDA (0.8 g/kg/day) on body composition. Indeed, a recent position statement by the PRO-TAGE study group advises consumption of 1.0-1.2 g/kg/d in older adults during weight-stable conditions to aid in the maintenance of lean body mass and function. Practical achievement of this level of protein intake is often difficult for obese, older adults undergoing weight loss, yet may be critical to offset weight loss-associated lean mass loss. Preliminary data from our group show a lean mass sparing effect of high protein consumption during caloric restriction. In post-menopausal women undergoing a 5-month intentional weight loss program, consumption of a high (1.2 g/kg/day) versus low (0.6 g/kg/day) protein diet was associated with 50% attenuation (17% vs. 37%) of lean mass loss. While promising, results have yet to be translated to functional changes in a tightly controlled trial of weight loss in obese, older adults. The primary goal of this study is to determine whether adherence to a high protein (≥1.0 g/kg/d) weight loss program results in improved physical function by favorably affecting body composition compared to weight stability in obese, older adults. This will be accomplished by conducting a 24-week trial in 124 obese (BMI 30-40 kg/m2), older (65-79 years) men and women, at risk for mobility disability, randomized to either: (1) high protein intake (≥1.0 g/kg/d; n=62) during weight loss, or (2) weight-stable control (n=62).

This research will evaluate nutrition requirements for missions at high altitude (i.e. >7800 feet above sea level) and the information obtained can be used to optimize nutrient content specifications for combat rations. The objectives are: Determine whether loss of lean body mass resulting from negative calorie balance over a 22-d period at high altitude can be prevented by increasing dietary protein intake. Determine the efficacy of carbohydrate (glucose and fructose) supplementation on aerobic exercise performance at sea level, acute exposure to high altitude, and in response to 22-d period of negative calorie balance at high altitude. Determine cognitive function, sleep patterns, and behavioral responses to high altitude and underfeeding. Determine appetite and eating behavior in response to high altitude and sustained underfeeding. Examine the effects of high altitude, negative calorie balance, dietary intake manipulations on gut health.
