Filter by:Several studies have shown differences in health-related outcomes by dietary pattern. These patterns have included those participants following vegan (no meat, poultry, fish, dairy, or eggs), vegetarian (no meat, poultry, or fish), pesco- vegetarian (no meat or poultry), semi-vegetarian (red meat and poultry ≥ 1 time/month and < 1 time/week), or omnivorous diets. These studies have shown that of these dietary patterns, vegans have the lowest BMIs, lowest prevalence of Type 2 diabetes, and lowest amount of weight gain over 5 years. In addition, vegetarians have significantly better metabolic risk factors as compared to non-vegetarians. While these initial observational studies have shown benefits to consuming more plant-based diets, there have been no randomized trials examining the differences in health outcomes among these dietary patterns. To begin exploring this research area, the investigators will conduct a pilot study which will randomize participants to one of the 5 dietary approaches. Participants (n=75) in the NEW DIETs Study will be recruited to follow their randomly assigned diet for 8 weeks and attend weekly sessions to learn about nutrition and cooking.
Malaysia has increasing challenges in lifestyle related diseases, which is related to eating habits and disorders. According to the National Health & Morbidity Survey in 2011; it was reported the prevalence of obesity is 15.1% in 2011; or 2.5 million of the population,; an increase of 7/9% when compared to the 14% prevalence in 2006. Binge eating is a symptom described in various eating disorders. It is an under-diagnosed medical condition closely linked to higher body mass index (BMI) or obesity as well as personality psychopathology, psychiatric and psychological disturbances. Meta-analysis has demonstrated that extremely strict restriction in dietary calorie and fat intake is needed to achieve meaningful weight loss. Appetite and satiety are influenced by extremely complex central and gut-related hormonal systems which modulate the regulation of food intake Centrally acting hormones include Neuropeptide Y (NPY), agouti gene-related peptide, orexin which are appetite-stimulating, melanocortins and alpha-melanocortin-stimulating hormone which promote satiety. Gut-related peptides include ghrelin secreted by the stomach and the duodenum has orexigenic (appetite stimulating) effect; leptin secreted by adipose tissue has anorexic (appetite inhibiting) effect, cholecystokinin, glucagon-like peptide-1 (GLP-1) secreted by the proximal gastrointestinal tract which has slight anorexic effect, and peptide YY (PYY). Appetite and obesity have also been commonly related to stress and may influence binge-eating episodes. Previous studies have demonstrated that high stress hormone cortisol is associated with increased appetite and cravings, with preference for high carbohydrate content, thus leading to weight gain. In the previous study performed by our group on 738 normal subjects who were staffs of the Ministry of Health, Putrajaya, we found a prevalence of 19% binge eating behaviour, 83% of whom were either obese or overweight. GLP-1 analogue used for the treatment of type 2 diabetes and is also shown to produce and maintain weight loss. Liraglutide, which provides a supra physiological amount of GLP-1 may cause appetite inhibition thus may benefit in reducing binge eating. The aim of this study is to closely observe the extensive profile of neuropeptide Y, ghrelin, leptin and GLP-1, influenced by a standard meal in binge eaters in comparison to non-binge eating controls. In addition, we aim to determine the association between binging and the respective appetite-related hormones and also cortisol. Finally we will also be assessing the efficacy of novel hormonal treatment of Liraglutide in reducing binge eating.
The purpose of this study is to examine the effectiveness and applicability of different interventions designed for enhancing overall wellbeing. Lifestyle changes, as well as psychological and physiological health variables are assessed. The interventions are based on the principles of cognitive behavioural therapy, and delivered either face-to-face, via mobile phone application, or Internet.
1. The primary objective is to determine the effect of fruit polyphenols on postprandial lipoprotein triglyceride metabolism after consumption a standard high carbohydrate/fat breakfast meal with a beverage rich in fruit-derived polyphenols compared to energy and macro-/micro-nutrient matched control beverage (acute, Part 1). 2. Secondary objectives are: 1)to assess the effects of consuming daily for 8 weeks (chronic, Part 2) a beverage rich in fruit polyphenols compared to an energy and macro-/micro- nutrient matched control beverage on fasting glucose, insulin, lipids and markers of oxidative stress; and 2) to assess the effects of these beverages on meal-related changes in metabolic and oxidative stress measures after 8 weeks daily consumption.
Child overweight has become one of today's most important public health concerns. Engaged and skilled parenting that models, values, and encourages healthy eating habits and a physically active lifestyle can play a key role in childhood overweight prevention and reduction. Primary care providers are well positioned to intervene with children and their parents, but face many barriers in addressing child overweight. A child overweight treatment approach is proposed for the primary care setting to facilitate parents' active involvement and self-efficacy in promoting healthy eating habits and physical activity for their children. We will test the following hypotheses: Hypothesis I (primary hypothesis): Children assigned to the intervention group will improve more in weight status (measured by BMI percentile) than children in the control group. Hypothesis II: Primary care providers assigned to the intervention group will improve more in their competence in addressing child overweight than the providers in the control group. Hypothesis III: After the intervention, parents in the intervention group will have more involvement and self-efficacy in promoting healthy weight for their children than parents in the control group. Hypothesis IV: Compared to the control group, the intervention group will improve more in family diet and eating, physical activity behaviors, as well as parental attitude and beliefs. Eighty children five to eleven years old who are overweight or obese will be recruited from two pediatric and two family practice clinics in southern Appalachia. Children will be randomly assigned to intervention and control groups based on clinic affiliation. Parents of children in the intervention group will participate in four clinic-based group sessions using the NIH We Can! curriculum moderated by a trained clinic provider, two individual brief motivational interviewing visits with their clinic provider, and four follow-up phone calls with the project coordinator or registered dietician. Parenting behaviors and attitudes, and family eating and activity habits, and children's weight status will be assessed at baseline, at the completion of the intervention, and at six months after the intervention. Changes in the assessments will be compared between treatment and control groups. Changes in provider and parent attitudes and perceptions about this treatment approach,adherence to the program, and estimates of associated time will be measured.
The purpose of this study is to compare three methods of delivering behavioral weight loss treatment.Participants are randomly assigned to one of three 18-month weight loss treatments (group, individual, or smartphone treatment). Participants who are assigned to group treatment will attend group meetings weekly for the first 6 months, then every 2 weeks for 6 months, and then monthly for the final 6 months. Participants who are assigned to individual treatment will attend one-on-one sessions with a weight loss counselor every month for 18 months. Participants who are assigned to smartphone treatment will use a smartphone to learn and practice weight loss skills. They will also attend one-on-one sessions with a weight loss counselor every month for 18 months. Assessment visits are conducted at baseline, 6, 12, and 18 months.
The proposed study will address the effect of developed novel food products through processing innovation on motivation to eat, biomarkers of satiety, nutrient bioavailability and gut health using in vivo studies and validating new in vivo approaches. Specifically in this protocol we will address, in a short human intervention study the effect of a potentially satiating product on appetite, appetite biomarkers, particularly the influence on gut microbiota, tolerance and safety of the products in healthy obese and overweight volunteers in free living conditions.
The study was designed to answer the primary question: the consumption of one apple three times daily between meals reduces serum levels of cholesterol above 240 mg/dL in overweight women? The second and important hypothesis was designed for evaluate the reduction in body weight by intakes of fruits. Therefore, the increased consumption of apples could displace the consumption of other foods and promoting satiety and input significant reduction in body weight compared to other fruit (Pear) of similar nutritional composition or food (cookies) made from oats with fiber and total calories similar to those observed in these fruits. To demonstrate the effectiveness of these supplements we used a clinical trial with three arms (apple, pear and oatmeal cookies).
Our goal is to investigate how hormones that control blood sugar, hunger, and stomach emptying change with puberty and being overweight. These substances change with a meal. - For this, we need to compare lean and overweight children. - We need to study them before and during puberty. - All children in the study will be tested before and after a liquid meal.
The present study will test the effectiveness of two different approaches for preparing overweight/obese individuals for weight loss: 1)providing important information about weight control, including dispelling common myths; or 2) developing a consistent sleep and eating routine to prepare for the challenges of a weight control intervention.
