Filter by:This is a randomized controlled trial of the effects of chewing gum on body weight. The investigators will randomly assign 200 overweight or mildly obese adults to one of two groups. Participants must be otherwise healthy and ages 19-50. The control group will receive only printed information on optimal diet and increasing physical activity. The intervention group will be instructed to chew gum following meals and in place of snacks for a minimum of 90 minutes per day. The intervention group also will receive the same information on optimal diet and increasing physical activity as the control group. In this 8-week intervention, the primary outcome will be change in body weight, and secondary outcomes will be changes in body mass income (BMI), waist circumference, and blood pressure. The protocol includes 3 clinic visits to assess outcomes: baseline, 4 weeks after randomization, and 8 weeks after randomization. Adherence to the gum chewing protocol will be assessed at clinic visits and during 2 telephone calls at 2 weeks and 6 weeks post-randomization. The investigators' hypothesis is that gum-chewers will lose more weight than those who receive information only.
Nearly 20% of women do not return to their pré-gestacional body weight. The purpose of this study is to investigate the effect of diet and socio-demographics factors during gestation and postpartum period to body weight change after delivery. This is a clinical trial with 180 women interviewed at 1 (baseline), 2, 3, 4, 5 and 6 months postpartum. The dietary data were obtained by employing the Food Consumption Frequency Questionnaire with reference to the first and sixth months of postpartum.
PF-04620110 is a novel compound proposed for the treatment of Type 2 diabetes mellitus. The primary purpose of this trial is to evaluate the safety and tolerability, pharmacokinetics, and pharmacodynamics, of multiple oral doses of PF-04620110.
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 objective of this study is to determine the acute effects of a dairy supplement compared to a soy supplement on oxidative and inflammatory stress in overweight and obese subjects in the absence of any changes in adiposity.
The purpose of this research is to test the effect of manipulating eating frequency on hunger and the reinforcing value of food in 50 overweight/obese adults participating in a 6-month behavioral weight loss intervention.
The purpose of this study is to evaluate the efficacy of homeopathic treatment in pregnant women with overweight and class I obesity with suspicion of a mental disorder.
The purpose of this study is to examine the effectiveness of the South Beach Diet™ and South Beach Diet™ products compared to a traditional calorie restricted diet.
Dietary protein differing by their amino acid composition could modulate undesirable metabolic and functional responses to a meal rich in saturated fat and sugars. This study aims at examining the specific effects of dairy protein with different cysteine contents on the postprandial undesirables effects elicited by the ingestion of a high fat meal in overweight subjects.
Type 2 diabetes and prediabetes, which are mainly caused by a lack of physical activity and excess weight, put people at an increased risk of cardiovascular disease. This study will compare the effects of a weight loss diet versus a weight loss diet plus an exercise program on body composition and cardiovascular factors that are early predictors of future cardiovascular disease in overweight and obese people with type 2 diabetes and prediabetes.
