Filter by:The purpose of this study is to to assess the glycemic index and the satiating properties of different Quinoa varieties, using a Visual Analogue Scale in a sample of healthy overweight subjects.
The hypothesis is that toddlers with parents who are randomized to a parenting intervention and toddlers with parents who are randomized to the maternal intervention focused on maternal diet and physical activity will be more likely to have weight status within normal and to consume a healthy diet and engage in physical activity than toddlers with parents in a placebo (safety) intervention.
Obesity and metabolic syndrome are prevalent among prostate cancer patients. Having an elevated insulin level in the blood is associated with a shorter median time to cancer progression and median overall survival in patients with an elevated PSA after prior treatment. Androgen deprivation therapy (ADT) with drugs like bicalutamide is frequently used in this patient population,with no proven benefit, which may increase mortality and morbidity.This study evaluates how metformin in combination with bicalutamide affects prostate cancer.
There are an increasing number of individuals in the United States with obesity, and this is a major health concern with links to many chronic diseases. Impairments in protein metabolism with obesity may disrupt muscle function and modify the dietary protein requirements in obese individuals. Further, overweight and obese type 2 diabetics exhibit dramatically reduced skeletal muscle mass compared with lean, healthy controls. Surprisingly, the influence of being overweight or obese on this decline in muscle mass remains understudied, despite clear evidence that similar metabolic impairments typically exist in these populations prior to the development of overt diabetes. Protein ingestion provides the amino acid building blocks to synthesize and repair muscle proteins in adults. Previous research has shown that the muscle protein synthetic response to food ingestion may be reduced in overweight/obese adults. However, this research provided the 'free' amino acids in small portions every 15 min during the postprandial period. In free living conditions, however, it is more common to consume protein dense foods in single portions. Currently, there is no information available on how eating protein rich foods affects muscle protein synthesis in overweight and obese adults. This proposed research will fill this research gap by being the first study to compare the muscle protein synthetic response to the ingestion of a meal-like amount of high quality protein in lean, overweight and obese adults. The objective of this study is to determine the muscle protein synthetic response after the consumption of 35g pork protein in lean, overweight and obese adults. In order to assess this objective the researchers propose to use primed continuous infusion of L-[ring-13C6] phenylalanine to measure muscle protein synthesis rates after the consumption of dietary protein. In a parallel design the researchers will study 13 obese (BMI 30-39.9 kg/m2) participants, 13 overweight (BMI 25-29.9 kg/m2), and 13 age-matched lean controls (BMI 18-24.9 kg/m2) between the ages of 20 and 45 years. All subjects will be sedentary and weight stable for the previous 6 months. On the test day, subjects will remain sedentary for the determination of muscle protein synthesis in both the fasted state and after consumption of the protein meal. Blood and muscle sampling will occur on the test day.
The main aim of this study is to evaluate the bioavailability of blackberry juice anthocyanins, with or without ethanol, in normal weight and overweight/obese adults.
Aim: - The overall aims of this study to look at what changes are seen overweight and obese (very overweight) children, as they get thinner. - Specifically the investigators are interested in the chemicals and bacteria that children pass in their urine and stool because looking at how these change as it tells us about how their gut and other bodily systems are adapting. Hypothesis: Metabolic profiling is a useful and accurate tool for observing and monitoring weight loss in children Study plan: - To observe this weight loss process in children, the investigators will be attending a commercial weight loss camp called 'MORElife' which takes place every year in Leeds. This camp is attended by children age 8-17years who are overweight or obese, for between two and five weeks. It aims to help them lose weight through a structured diet, exercise, education and support program. - The investigators plan to, with the consent of the parent and agreement the child ask if they would kindly give us a urine sample at the beginning and end of their time on the camp. For those staying longer than 2 weeks the investigators will also ask for a sample in the middle if possible. - In addition for those children who consent, the investigators will also ask for a small stool (poo) sample at these same time points although there is no obligation to participate at all in the study and it will not affect their time on the camp whatever they decide. - Any children who will be attending the MORElife reunion (arranged by the camp at around 10-12 months after) who agree will be asked for a final urine and stool sample to look at the long-term effects. - Each sample is given a code so as to remain anonymous, frozen and transported to the university laboratory to be analyzed. - With permission and consent the investigators will also collect some information about the children such as, weight and height from the camp coordinators as well as samples of the diet that they will be fed and example of exercise activities to give a full picture so that results can be as accurate as possible.
Background and Aims: The "5:2 diet", a form of intermittent energy restriction, has been popularized in Europe and USA. The rationale behind this approach is that two days of dieting is potentially more achievable, yet long enough to reduce overall weekly energy intake. However, this specific approach is lacking in evidence. Therefore, we are keen to investigate the effectiveness of this form of intermittent energy restriction compared with a control intervention (providing dietary and exercise advice only), in overweight, Chinese subjects, for an intervention period of 12 weeks. Design and Methods: This will be a randomized controlled trial, with 15 subjects in each arm, for an intervention period of 12 weeks. Subjects randomized to the treatment group will take three packets of a meal replacement product (Optifast®) per day during two consecutive fasting days, and take a healthy balanced diet that meet estimated energy requirements for the remaining five days. Subjects randomized to the control group will be given general diet advice and allowed to eat ad libitum throughout the study period. Measurements and laboratory tests will be done at baseline, 4 weeks and 12 weeks. Adherence to the dietary interventions will be assessed at 4 weeks and 12 weeks using 7-day food diaries. Significance: This will be the first study looking at an Asian population and will serve as a pilot towards a larger randomized trial. If this approach is found to be safe, effective and easier to adhere compared to the traditional continuous energy restriction, then it will be a very valuable option in the treatment of obesity, which has become an increasing problem globally including Singapore.
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 the investigators 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 participants in free living conditions.
This study evaluates the impact of increased intake of fruits and vegetables and whole grains on markers of inflammation and gut microbial composition. The treatment groups are 3 servings of whole grain per day; 5 servings of fruits and vegetables per day; and a control (3 servings of refined grains per day provided).
The effects of mini-trampoline training on balance, cardiorespiratory fitness, strength and neuropsychological parameters in an overweight or obese population are unknown. The aim of this 2-arm randomized controlled trial is to compare the effects of a 12-week mini-trampoline training and a 12-week nordic walking training on balance, fitness and strength in overweight/obese individuals.
