Filter by:This study will describe the phenotype (physical and behavioral traits) of overweight and obese people. It will characterize the hormones, metabolism, food preferences, fitness and physical activity levels, sleep patterns and thought processes in people with and without weight problems. Genetic material will be collected for studies of the internal codes that influence body weight. People over 18 years of age from all weight categories (lean, overweight, obese) who are reasonably healthy may be eligible for this study. Participants undergo the following tests and procedures: - Physical exam, electrocardiogram, blood and urine tests, instructions for recording food intake for 7 days - Metabolic studies for menstruating women. - Resting metabolic rate to study how many calories the body burns at rest. - Mixed meal test to measure hormones such as insulin that regulate blood sugar. - Glucose tolerance test to determine how sensitive the body is to insulin. - 24-hour energy expenditure to measure the amount of oxygen breathed in and the amount of carbon dioxide breathed out. - Repeat 24-hour energy expenditure. - Diurnal blood sampling and temperature assessment to study the body s internal clock. - Air-displacement plethysmography (Bod Pod) to measure body composition. - Dual energy x-ray absortiometry (DEXA) to measure body fat and bone density. - Repeat Bod Pod and DEXA. - Anthropometric measurements and bioelectrical impedance to measure height, weight, and circumferences, skinfold thickness, fluid status and percentage body fat. - Bromide dilution to measure the amount of water not in cells in the body. - Doubly labeled water to measure the amount of calories burned in a 7-day period. - 24-hour diet reports. - Endothelial reactivity to measure how the blood vessels stretch or dilate for assessing cardiovascular health. - Treadmill or bicycle exercise capacity test. - Physical activity monitor. - Unicorder to detect any breathing difficulties that may interfere with sleep. - Fat and muscle biopsy to look for variations in gene expression in fat tissue and muscle. - Neurocognitive testing to check memory, decision-making, hand-eye coordination, and reasoning. - Evaluation of mood problems and assess personality type. - Evaluation to assess the quantity and quality of pain experienced. - Taste testing to determine the response to bitter, salty, sweet and sour substances. - Occupational therapy evaluation to explore the subject s adaptations, if any, for performing personal, social or professional activities; the subject s views on his or her weight, body size and shape, and strategies to control weight.
The intervention program "Obeldicks light" is developed for overweight children aged 8-16 years. This intervention is gender - and age specific. The 6-month intervention is based on nutrition course, behaviour therapy and exercise therapy. The evaluation compromised quality of structure, process and results of the intervention. 300 participants in a randomised controlled group design will be evaluated at 4 time points: baseline, end of intervention, 6 months after end of intervention and 12 months after end of intervention.Primary outcome measure is change of weight status as standard deviation score of BMI. Drop-outs will be interviewed to improve the intervention.
Several studies have reported greater weight loss when following high meat-protein diets but limited studies have studied high plant-based protein diets. Thus we aim to investigate the effect of high protein diets in weight management and also to investigate the superior protein source in achieving this effect. In addition, we aim to develop dietary intervention strategies that are realistic and sustainable.
The prevalence of overweight in the United States Air Force (USAF) is about 22%. The objective of this study is to compare the effectiveness of a minimal contact behavioral therapy plus usual care group(MCBT+UC) using a controlled experimental comparison of usual care(UC). Subjects are USAF personnel who are 5lbs below their Maximum Allowable Weight (MAW) and heavier. The primary hypothesis is that: MCBT+UC will have significant weight loss as compared to UC.
This 12-month randomized controlled trial, sponsored by NIH/NCI, aims to reduce BMI in obese adolescents (ages 11 -13) by intervening on physical activity and nutrition behaviors within primary care settings. PACE-PC is a theory-based stepped care program that enables pediatricians and primary care providers to intervene with obese adolescents to improve their anthropometric, metabolic, physiological, behavioral, and quality of life outcomes over a one-year period. The program integrates clinician counseling, health educator counseling, and phone and mail contact. It supports tailoring to the needs of obese adolescents and family members and promotes improved diet and physical activity behaviors, weight loss, and ultimately weight loss maintenance. Participants will be randomly assigned to the Enhanced Usual Care or the PACE-PC stepped care condition. The Enhanced Standard Care condition includes an initial visit and counseling by a physician, 3 visits with a health educator, and materials on how to improve weight related behaviors. The PACE-PC Stepped Care condition includes 3 steps (each lasting 4 months), with the first step being the most intensive: Step 1 includes: a physician visit, monthly health educator visits, biweekly phone counseling, and weekly dissemination of nutrition and physical activity information Step 2 includes: a health educator visits every other month, biweekly phone counseling, and weekly dissemination of nutrition and physical activity information Step 3 includes: monthly phone counseling and weekly dissemination of nutrition and physical activity information Participants randomized to the PACE-PC condition will be enrolled in Step 1 (the most intensive) for the first 4 months. Depending upon response at the end of Step 1, for the next 4 months adolescents will be triaged to Step 2 (less intensive) or will repeat Step 1. At 8 months, again based upon treatment response, triage will occur to either Step 3 (least intensive) or repetition of the previous step.
This is a NCI funded study which will develop and evaluate a cell phone application (mDIET) that can be used as an assessment and intervention tool to improve dietary behaviors and thus reduce weight in overweight and moderately obese (BMI 25-34.9) men and women ages 25-55.
Dietary carbohydrate is the major determinant of postprandial glucose levels, and preliminary evidence suggests that low carbohydrate diets improve glycemic control when accompanied by weight loss. To determine if glycemic control can be improved by varying dietary carbohydrate during weight loss, we compared two weight loss diets with different carbohydrate levels for the treatment of obesity-related type 2 diabetes over 24 weeks in the outpatient setting.
This randomized control study (sponsored by the NIH, NIDDK) is aimed at reducing BMI in overweight adolescents at risk for the development of type 2 diabetes. The study will examine whether an integrated primary care, web and cell-phone-based intervention can produce initial and sustained improvements in anthropometric, behavioral, metabolic, and physiological outcomes in overweight adolescents. The primary goal is to reduce BMI (Body Mass Index)in overweight adolescents.
Background: During the 1990s, the prevalence of the metabolic syndrome in the Netherlands ranged from 3% in women of 20-39 yrs to at least 33% in men 55 yrs and older and it is expected to increasing. Prevention is therefore warranted. In this respect the amount and type of fat in the diet deserves attention. Recently, an intervention study reported that a diet high in mono-unsaturated fatty acids (MUFA) such as from olive oil, increased insulin sensitivity in healthy subjects. However, additional beneficial effects can be expected from the Mediterranean diet as a whole. Hypothesis: Replacing saturated fatty acids (SFA) by mono-unsaturated fatty acids (MUFA) will improve hyperinsulinemia and dyslipidemia, and a typical Mediterranean diet will even have more pronounced effects. Study objectives: To investigate the impact of the Mediterranean diet, and especially the intake of MUFA, on markers of the metabolic syndrome in high-risk subjects. Methods: The controlled dietary intervention will include 60 subjects aged 40-65 years with moderate abdominal obesity. After a run-in diet for 2 weeks they will be assigned randomly to receive one of the three diets for a period of 8 weeks. Measurements of serum insulin concentration and other parameters will be carried out at weeks 2 and 10. Expected results: Our study will provide information on the role of MUFA and the expected beneficial impact of other factors of the Mediterranean type of diet on the metabolic syndrome.
This study represents the first administration of GSK376501 in humans and the goal is to evaluate its initial safety and tolerability. The way the human body processes GSK376501 will also be determined.
