This double blind placebo study will take place over an 8 week treatment period of diet and exercise. All participants (n=16), in two groups, will be placed on the same hypocaloric diet and exercise program. Participants will be matched into pairs based on body fat % and then assigned into a test group & a placebo group. The placebo will be in the form of a powdered isoenergetic beverage with carbohydrate similar in taste & appearance to the powder BCAA supplement that the test group will receive. The test group will be put on 0.342g/kg of BCAA per day, partially accounted for through their diet with the rest provided by a BCAA supplement. At baseline, 4 weeks and 8 weeks habitual 3 day food logs, waist to hip ratio and BodPod measures of body fat & lean mass (both percentage & absolute values) will be taken for all participants.
Participants will complete a one-month intervention where they are will restrict their daily food intake to an 8-hour time period, i.e., between 1200 to 2000 hours. During the remaining 16-hour intermittent fasting period (2000 to 1200 hours) participants will be allowed to drink zero calorie beverages (diet soda pop, black coffee, tea, water, etc) in order to maintain normal hydration. There will be no attempt to restrict food intake. Rather simply to restrict the time period each day when food is consumed. Participants' body mass, fat mass, and non-fat mass will be monitored non-invasively using a weigh scale and densitometry via air displacement (Bod Pod) at 0, 2 and 4 weeks following the dietary intervention. Also, participants will be interviewed following the final body composition measure to assess whether or not they continued to follow the intermittent fasting approach.
This is a 6 month long study to evaluate the inclusion or exclusion of beef within a weight loss program.
The present protocol is mainly involved in the understanding of the local interaction between the released products by fat tissue and hormones production of bone tissue. These complex interactions between adipocyte and osteocyte activities could explain the mechanisms of the body responses to the strategies of weight loss that include diet and/or physical activity program, as well as the side effects encountered by these interventions. Adolescence is a period of development characterized by many metabolic and somatic changes that may influence weight. Weights bearing physical activities are a key factor allowing body composition changes (i.e. fat and bone tissue). The difficulties of managing weight and the onset of overweight and obesity during this very important growth spurt lead to various hormonal dysregulation. The specific mechanisms of the evolution and interactions between these two parameters (fat and bone tissue) are not yet elucidated; therefore our aim is to analyze the possible connections between fat tissue and the quality of the skeleton in order to reduce related risks of the consequence of weight loss in obese individuals.
The investigators aim to evaluate the effect of a 6-month intervention (counseling) focused on weight loss in a group of overweight or obese women previously treated for early breast cancer. Intervention is designed to improve adherence to a healthy diet or/and to increase physical activity and decrease sedentary time, taking advantage of a pedometer-like device.
The aim of this study is to examine the impact of lifestyle intervention on postpartum weight loss. So the investigators will have two groups in this study. In Experimental group women will receive the Healthy Lifestyle Intervention. This intervention will have been delivered during 12 weeks. In Control group women will receive general information via pamphlet about postpartum period and tips for stress management.
The purpose of this study is to determine the feasibility and efficacy of a 6-month weight loss intervention program for obese working adults through a popular social networking site - Facebook.
A phase II, randomized, double-blind, placebo-controlled, in parallel groups clinical trial to assess the safety and efficacy of dietary supplementation with tryptophan to achieve weight loss, and its neuropsychological effects in adolescents with obesity.
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.
