Filter by:This is a cross-over intervention study designed to evaluate how four weeks of time restricted feeding (16 hours fasting and 8 hours feeding), compared to four weeks of a more traditional eating pattern (12 hours fasting and 12 hours feeding), affects resting energy expenditure, subjective and biochemical markers of satiety and hunger, body composition, cardiovascular health, substrate utilization and fitness in male competitive runners.
This is the first study of its kind to assess and test an intervention to improve biological rhythms and general health of shift workers, specifically first responders with San Diego Fire and Rescue. In a randomized control trial, investigators intend to measure the health impact of Time Restricted Eating in emergency responders who work a 24-hour shift schedule.
Adult Muslims are obliged to start fasting during the month of Ramadan. Fasting entails refraining from all food, drink, tablets and injections(vitamins & fluids) between sunrise and sunset; a period which varies by geographical location and season. People with type 1 Diabetes are among those who are risky to fast this holy month in the Muslim faith and thus are exempted from fasting. Yet many patients fast in spite of medical advice and religious exemption and for those patients, healthcare professionals should provide the utmost care and continuous diabetes education. Different diabetes education modalities exist like DSME (Diabetes self-management education with proven efficacy. One modality is the Diabetes Conversation Map which delivers diabetes education interactively through a series of maps that address different issues in diabetes management and includes a specially designed Ramadan map. In this study, two modalities of Diabetes focused Ramadan education will be compared regarding aiding patients to fast Ramadan safely. One modality will be Diabetes conversation maps and the other the International Diabetes Federation Education modules.
Participants will undergo one day of habitual eating followed by 36 hours of water only fasting and final day of habitual eating of the exact same diet consumed on the first eating day. Blood draws will be performed on Day 1 in a 10-12 hr fasted state and 2 hour postprandial state and again on Day 3 in a 36hr fasted state and a 2 hour post prandial state. Microbiome samples and blood glucose data will be collected throughout the course of the study.
According to normal physiology, the longer fasting period allows food particles to pass stomach through small intestines to minimize intragastric content. The practice guidelines recommend 2-hour fasting period for clear fluid (including water, pulp-free juice and tea or coffee without milk), 4- hour fasting period for breast milk and 6-hour fasting period for non-human milk and solid food to reduce risks of pulmonary aspiration. As a result of longer fasting period, patients tend to experience preoperative dehydrated states and intraoperative hypotension. Patients' demographic data will be obtained from charts. Parents will be asked for type, volume of fluid/food intake and NPO time. This study will be done at BCH's Gastroenterology Procedure Unit (GPU) theaters to measure actual intragastric volume and pH at the beginning esopagogastroduodenoscopy procedures. We hope to demonstrate the relationship between NPO time and actual intragastric volume which provide sufficient data of NPO time to ensure patient's safety.
This study aims at assessing whether breath acetone concentration is a good bio-marker of instantaneous energy balance in healthy subjects.
Prospective comparative cohort study including 159 pregnant women at the third trimester recruited from the antenatal clinic at EL-Demerdash outpatient clinic, and followed up during the holy month of Ramadan (from 18th June To 16th July 2015). The patients recorded their pattern of fasting during Ramadan then grouped into three groups A, B, C regarding fasting state A- Non fasting group B- Partially fasting group C- Totally fasting group
The primary aim of this study is to examine the effect of fructose ingestion on serum FGF-21 levels in humans.
Effectiveness of fasting or fasting-mimicking diet has been proved an effective approach to treat metabolic and autoimmune diseases in mice. However, clinical trials performing prolonged fasting with more than 7 days have not been reported. Investigators conduct an open label, phase I/II clinical trial to evaluate the safety and effectiveness of the 21-day fasting-like diet in the treatment of metabolic and autoimmune diseases.
The investigators want to establish a new model of acute febrile disease by mimicking the conditions seen in hospitalized patients in regards to inflammation, immobilisation and fasting. In this new model of disease, healthy young adults will be given lipopolysaccharide (LPS) to induce endotoxemia and inflammation/fever and then fast and bedrest for 36 hours. Glucose, fat and protein metabolism will be investigated using clamp technique and tracer methodology together with intracellular signalling pathway activation in muscle and fat biopsies. This new model of disease will later be used in another study to investigate different protein supplement´s effect on muscle waste during acute febrile disease.
