Filter by:The purpose of this study is to determine whether adding a peer-based intervention based on an outward bound model is more effective than a standard behavioral weight intervention for helping adolescents lose weight.
We propose to conduct a randomized study of standard behavioral weight-loss treatment to test if using an electronic diary with or without tailored feedback will improve adherence to self-monitoring and subsequently improve weight loss. Subjects will be randomly assigned to different methods to self-monitor food and exercise habits: (1) use of the traditional paper diary , (2) use of a personal digital assistant (PDA), or (3) use of a personal digital assistant that also provides daily feedback.
The majority of patients with Type 2 Diabetes are obese and weight loss is known to improve diabetes outcomes and reduce the need for anti-diabetic medical. This 8-week Telehealth study will compare the effects of standard weight loss advice given in a clinic setting to weight loss advice delivered in the home using an interactive cable television technology called Healthium.
The primary aim of this study is to assess long-term weight loss efficacy of zonisamide relative to placebo in obese patients prescribed a dietary intervention.
The primary purpose of this study was to compare weight loss achieved through a behavioral online intervention vs. a commercial self-help website. The investigators hypothesized that there would be no difference in weight loss between groups.
Men infected with the HIV virus (the virus that causes AIDS) often lose weight even though they may try to eat more food to gain weight. The reasons for this weight loss are not clear. Many men with HIV have low levels of testosterone in their blood. Testosterone is a hormone that is naturally produced in the bodies of both men and women and has important effects on building muscle and bone mass. The purpose of this study is to find out if providing additional testosterone to HIV infected men who have low testosterone can help them gain weight, increase their muscle mass, and feel better. The study will also help see if testosterone improves the efficiency with which your body produces and uses energy including fat. The dose of testosterone being used in this study will raise testosterone levels in the blood to higher than normal levels (2-3 times normal level).
The purpose of this study is to compare the effectiveness of Weight Watchers, brief behavioral treatment, and a combination treatment. We hypothesize that a combination treatment will achieve greater weight losses than Weight Watchers alone.
The purpose of this study is to compare the efficacy and safety of topiramate 96mg and 192mg daily) with placebo in the treatment of obesity following an intensive non-pharmacologic weight loss program.
Overweight and obesity is increasing in most countries, including Norway, and the optimal diet for reducing weight is under discussion. The present study in overweight and moderate obese individuals compares a low glycemic load diet with a standard low-fat diet (as recommended from the National Nutrition Council) in an open, randomized trial over 12 months, with changes in weight loss and changes in cardiovascular risk markers as endpoints.
Twelve obese patients approved for gastric bypass surgery will be randomized to either receive an MCT-based or LCT-based liquid diet for a 4 week period. These diets will be identical except for the quality of the fat. The intervention will be double-blinded. Six patients will receive a daily diet consisting of 5 liquid meals using the HMR 800 meal replacement product (Health Management Resources, Inc; 160 calories/shake) with 44.5 grams MCT oil (Life Enhancement Products, Inc., Petaluna, CA; 8.3 kcal/gm) added. Six patients will receive the same HMR diet but with 41 grams LCT oil (corn oil; 9 kcal/gm) added. Patients in both groups will be given a list of supplemental foods that are suitable for the study. They may choose to eat up to an additional 700 kcal per day from this list and will be asked to complete food records for monitoring of their caloric intake. Patients will undergo gastric bypass surgery after 4 weeks of being on their diets. Patients in both groups will be seen weekly by a registered dietitian and a physician. Blood pressure and weight will be recorded, and any adverse events will be noted and cared for as is appropriate. Dietary instruction will be reviewed as needed.Both diets will be 1170-1870 kcal/day, consisting of 36% CHO, 26.2% protein, and 37.6% fat. The MCT diet will contain 30.2% of total calories at MCT oil. The percentages given are based on the shake and oil consumption only (1170 kcal/day). The remainder of the diet will vary according to patients' selections from the list of permitted foods, up to an additional 700 kcal/day (for the total 1870 kcal/day). All subjects will receive a multi-vitamin each day. Subjects will also receive two Fibercon capsules per day to prevent possible bowel changes associated with being on a full liquid diet. During surgery, biopsies of visceral and omental adipose tissue, as well as subcutaneous abdominal adipose tissue, will be obtained. Tissue will be analyzed to determine mRNA levels of key enzymes in fatty acid esterification, lipolysis, and oxidative disposition. This preliminary phase will be conducted to determine whether visceral, omental, and subcutaneous abdominal adipose tissue behave similarly when exposed to an MCT-based diet.
