Weight Loss and Exercise To Improve Rheumatoid Arthritis Cardiovascular Risk
Rheumatoid ArthritisThis is a small exploratory, randomized, controlled trial. Twenty-six older (ages 60-80 yr.), obese (BMI 28-40 kg/m2) persons with rheumatoid arthritis (RA) (seropositive or erosive) will be randomized to 16 weeks of a counseling health as treatment (CHAT) program or a supervised weight loss and exercise training (SWET) program.

Self-compassion and Nutrition (SCAN) Study
ObesityWeight LossThe purpose of this study is to examine the feasibility of two approaches for improving long-term weight loss success among individuals with severe obesity. All participants will receive a 15-week, standard behavioral weight loss program followed by either 8 weeks of a mindfulness self-compassion intervention or 8 weeks of a nutrition and cooking education intervention (determined via randomization procedures). Assessments of weight, physical activity, and other weight-related and psychosocial factors will occur at baseline, 4 months, 6 months, and 9 months.

Efficacy of Polyglucosamine for Weight Loss
Overweight and ObesityThe polyglucosamine, specification L112 is a medical device and in this clinical trial used for weight reduction of overweight and obese participants. The rationale for this study is to show that overweight can be reduced by taking 2 times daily 2 tablets with the main meals with the highest fat content.

A Test of Nutritional Interventions to Enhance Weight Loss Maintenance
OverweightObesity1 moreThe purpose of this study is to compare standard Behavior Therapy (BT), BT plus Meal Replacements (MR) and a condition focusing on the nutritional changes to the home food environment (HFE) on weight loss, weight loss maintenance, nutritional composition of the diet and psychosocial outcomes. A second aim is to determine the degree to which the specific targets of the experimental interventions do in fact change in the anticipated direction during the intervention and to evaluate whether such changes might account for improvements in weight loss maintenance. This study is important because it could provide the first evidence that the current standard of care for obesity lifestyle treatment could be improved by the addition of MRs or a program of comprehensive nutritional change.

Use of Chewing Gum to Facilitate Appetite Control and Weight Loss
OverweightObesityThis purpose of this study was to test the use of chewing gum as an adjunct to lifestyle modification to facilitate appetite control and weight loss in overweight and obese individuals.

Effects of Medium Chain Triglyceride Oil, Versus Olive Oil, for Weight Loss
OverweightThe primary aim of this research project is to determine whether the incorporation of food products containing medium chain triglyceride (MCT) oil in a weight-loss program results in a different degree of weight-loss and total and regional fat mass loss than the incorporation of extra light olive oil. The secondary goals are to test whether there are differences in in metabolic risk profile changes between the 2 diets. We hypothesize that men and women who consumed MCT oil as part of their weight loss program will lose more weight and body fat than those who consume olive oil in their weight loss diet.

Weight Loss and Cardiovascular Disease (CVD) Prevention Via a Whole Grain Diet in Men and Women...
Metabolic SyndromeThe purpose of this study is to determine if intake of whole grain foods as part of a hypocaloric diet enhances weight loss and improves cardiovascular disease risk factors in men and women with metabolic syndrome.

Weight Loss Maintenance in Primary Care
ObesityOverweightAfter a three month weight loss phase involving the use of meal replacements, participants are randomized into different weight loss maintenance conditions. Aim 1: To test the hypothesis that the meal replacement (MR) and reduced energy density eating (REDE) interventions, when added separately to the LEARN program, will produce superior weight loss maintenance compared to a LEARN-only intervention. Aim 2: To test the hypothesis that the weight loss maintenance condition that combines MRs and REDE will produce better maintenance of weight losses than either individual component and than the LEARN-only condition. Aim 3: To test the hypothesis that the two conditions receiving the REDE intervention will experience longer-lasting improvements in the energy density and nutritional composition of the diet compared to the two non-REDE conditions.

Weight Maintenance Study for 2007 Shape UP RI Participants
Weight LossThis study will focus on maintenance of weight loss achieved in the 2007 Shape-Up Rhode Island(SURI)program. We plan to recruit 180 individuals who participated in SURI and lost at least 10 pounds to take part in a 4-month weight loss maintenance program when the SURI ends. Participants will be randomly assigned to one of three groups: Education, Increased Exercise, or Daily Self-Weighing.

SHARE Study 4: Financial Incentives for Weight Loss
ObesityThe purpose of this study is to examine different types of monetary incentive paradigms for weight loss.
