Filter by:The effect of calorie restriction combined with low or moderate carbohydrate availability on exercise capacity, metabolism and metabolic health indicators will be measured in a randomized parallel group design. Forty overweight (BMI 25-30) and relatively inactive women (20-35 of age) will be included. These will be randomized into one of two experimental groups both receiving a calorie-restricted diet (-1000 kcal) combined with either low carbohydrate availability or moderate carbohydrate availability across a 10 day period. Laboratory-based physical capacity tests and blood and muscle sampling will be performed before and after the intervention. In addition, an additional follow-up test day will be performed after continuing the diet for another 48 h and then standardizing the pre-testing carbohydrate availability before repeating the tests of physical capacity.
The purpose of this study is to evaluate the function of the adjustment procedure with the Spatz4 in subjects with a BMI ≥ 27.
The goal of this clinical trial is to investigate the abundance of a natural odour in human cerebrospinal fluid in obese and lean participants after inhalation thereof. Participants will undergo blood sample collection and inhalation of either a natural odour or placebo through an inhaler in addition to a liquor puncture prescribed in standard of care context.
This study aims to evaluate the efficacy of a multi-component lifestyle interventions during pregnancy on promoting appropriate gestational weight gain, preventing GDM, and improving pregnancy, delivery, and neonatal outcomes among overweight or obese pregnant women. The intervention strategies are developed based on the transtheoretical model and mobile health (via WeChat Public Account in smartphone), and will be conducted online and offline. This study will recruit and follow-up 200 overweight or obese singleton pregnant women (pre-pregnancy BMI≥24 kg/m2) during the first trimester of pregnancy from Weifang maternal and Child Health Center, Shandong Province, China. The 200 overweight or obese pregnant women will be randomly allocated at a 1:1 ratio to either the intervention or control group, stratified by the categorical variables of age, BMI and parity. Participants in the control group will be provided usual prenatal care. The lifestyle intervention will last for approximately 6 months (from 10-14 weeks to 32-36 weeks of gestation). Follow-up timepoints included 10-14 weeks of gestation,24-28 weeks of gestation,32-36 weeks of gestation. The interventions are composed of health education related to gestational weight gain and healthy lifestyles, diet modification, active physical activity, regular individual in-person and telephone sessions, diet behavior monitoring, physical activity monitoring, and weight monitoring with Huawei smart watch. The hypothesis is that lifestyle interventions based on the transtheoretical model and mobile health will result in more appropriate gestational weight gain and lower risk of adverse pregnancy outcomes compared with usual care.
This project comprises an initial crossover placebo-controlled neurophysiological study to ascertain the effect of acute ketone ester ingestion on motor cortex plasticity, followed by a second 2-week intervention study aimed to compare the effect of a ketogenic diet versus ketone ester supplementation on motor cortex plasticity, resting brain function and structure, and metabolic and neuroendocrine responses.
To examine the acute changes in cardiometabolic and neurocognitive outcomes in response to exercise combined with ketone ester supplement in overweight/obese adults.
The prevalence of obesity and obesity-related diseases are on the rise worldwide. The widely accepted approach in dietary treatment of obesity is the calorie-restricted three meals-three snacks a day diet; however, alternative approaches are needed. This study was conceived with a view to comparing time-restricted eating, a method which can be easily conveyed and applied in overcoming obesity, to a six meals a day diet. 174 participants aged between 18-65 with a BMI>25 kg/m2 were included. Diet lists with similar calorie, macro counts suitable for their respective group were prepared. Anthropometric measurements, blood pressure, blood tests were analyzed before the study and at the end of the 8-week.
This trial aims to evaluate the impact on cardiovascular risk control in individuals in risk of being affected by hepatic steatosis through the implementation of a screening test (Fatty Liver Index) in Primary Care. Medical teams in a primary care center will be divided into 2 groups, with one group using the screening test in their clinical practice. The number of interventions on cardiovascular risk occurring in patients attended by each group of medical teams will be evaluated and compared.
The primary purpose of this project is to observe the effects of Cognitive Behavioral Psychotherapy-based weight-loss mobile application (Bi' Kilo) in 4 essential areas (Anthropometric, Biochemical, Psychometric, Cognitive) in overweight and obese individuals and to test whether these effects will persist after ten weeks. In this context, the original value of the proposed study is that a mobile application will be produced that is suitable for the culture and whose effectiveness has been scientifically proven. In our current project proposal, the measurements of the participants will be evaluated holistically together with both tests and inventories, as well as physical measurements and biochemical data. In this study, the usability of the mobile application to be developed will also be evaluated and reported. The study group of the research will consist of overweight and obese individuals. The first stage will be a pilot study to identify the shortcomings of the Bi'Kilo mobile application. After eliminating the deficiencies of the Bi' Kilo mobile application, a working group will be formed in the second phase of the research. At this stage, the sample will be divided into two different groups within the scope of the study and a study group and a control group will be formed. The study consists of three phases as preparation, implementation, and follow-up. Measurements of the participants will be made at the beginning (Anthropometric, Biochemical, Psychometric, Cognitive), at the end of the six-week implementation phase (Anthropometric), and at the end of the four-week follow-up phase (Anthropometric, Biochemical, Psychometric, Cognitive).
The goal of this clinical trial is to understand how the blood sugar-lowering hormone insulin works in healthy adults versus those who are at risk for type 2 diabetes. The study will use a drug called alpelisib, which interferes with insulin's actions in the body, to answer the study's main question: does the liver continue to respond to insulin's stimulation of fat production even when it loses the ability to stop making glucose (sugar) in response to insulin. Researchers will compare the impact of single doses of both alpelisib and placebo (inert non-drug) in random order (like flipping a coin) in study participants. Participants will be asked to stay twice overnight in the hospital, take single doses of alpelisib and placebo (one or the other on each of the two hospital stays), and receive intravenous (into the vein) infusions of non-radioactive "tracer" molecules that allow researchers to measure the production of glucose (sugar) and fats by the liver. Measurements will be done both overnight, while participants are asleep and fasting (not eating or drinking other than water) and while consuming a standardized diet of nutritional beverages during the following day. The objective is to evaluate the effect of lowering insulin levels, while maintaining constant mild hyperglycemia, on plasma glucose and lipid levels.
