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.
This study will look at the effect of 72 hours of fasting (not eating) on levels of proteins that are involved in metabolism. These proteins will be measured in blood and fat tissue. The investigators' hypothesis is that fasting will cause changes in these proteins.
Physical activity is a key stimulus for bone metabolism through both direct mechanisms (e.g., as a result of the applied load and/or impact) and indirect mechanisms (e.g., the activation of several metabolic pathways and the production of several mediators and effectors that have systemic effects). However, different kinds of physical activity exert different effects on bone and endocrine system. Aim of the study is to investigate the effects of different kinds of physical act...
One of religious duties for all healthy adult Muslims is fasting during Ramadan, the ninth month of Islamic lunar calendar. In this month, Ramadan observance fasted (no food and drink) from dawn to dusk. Studies demonstrated daytime fasting may pose a positive significant effect on metabolic health. Thus, this present study aimed to determine the effect of Ramadan fasting on body composition, metabolic profile, serum leptin and adiponectin levels in healthy men.
The purpose of Intermittent Fasting study is to investigate whether intermittent fasting could decrease the chronic inflammation levels in overweight/obese people.
Ramadan fasting entails abstinence from eating and drinking between dawn and sunset. During this month major changes in meal times and patterns, sleeping times and activity occur. Starvation is known to lead to a compensatory reduction in energy expenditure. However, the Ramadan fast is not synonymous with starvation as it involves intermittent periods of fasting followed by gorging. People who fast during Ramadan feel less energetic. However, little is known about the effects ...
The aim of the study is to find out the effects a specific religious fast (i.e. Bahá'í fast) has on certain metabolic parameters, hydration, psyche and circadian clock
The aims of this study are as follows: AIM 1: To examine the weight loss and weight maintenance efficacy of an alternate day fasting-high protein (ADF-HP) diet; AIM 2: To examine the effects of an ADF-HP diet on metabolic disease risk factors (plasma lipids, fasting glucose, fasting insulin, insulin resistance).
Non-alcoholic fatty liver disease (NAFLD) in patients with diabetes (T2DM) is increasing in prevalence and can lead to cirrhosis. Lifestyle intervention with caloric restriction (CR) is the cornerstone of treatment but remission is variable. Alternatively, the PI has shown alternate day fasting (ADF) is safe and well tolerated in obese patients and there might be additional beneficial effects. The objective is to combine the expertise of the PI with this novel intervention and ...
The goal of this study is to determine how effective repeated fasting over 26 weeks (6 months) is at improving risk parameters that are surrogate endpoints for cardiovascular diseases, metabolic dysregulation and cognitive impairments. Subjects will be randomized 1:1 to water-only fasting or to their ad libitum usual diet, with randomization performed within strata based on fasting history (≤180 hours or 181-720 hours of total fasting for >12 consecutive hours per episode in...
The aim of the study was to analyse the independent and joint effects of the components of the metabolic syndrome (MetS) on the incidence of diabetes in people with impaired glucose tolerance (IGT) and to assess the effect of acarbose by MetS status. Double-blind placebo controlled trial, 1,368 patients, follow-up time 3.3 years. MetS by ATP III definition with fasting plasma glucose of ≥ 6.1 mmol/l as limit for impaired fasting glucose (IFG).
This proposal aims to use well-validated methodologies such as dual energy x-ray absorptiometry (DEXA), frequently sampled oral glucose tolerance tests (fsOGTTs), and hyperinsulinemic euglycemic clamps to characterize the metabolic effects of 12 weeks of aripiprazole treatment following chronic pretreatment with olanzapine, quetiapine, risperidone or ziprasidone. We hypothesize that switching to aripiprazole treatment will induce improvements in total body adiposity, inf...
The survey is designed to investigate whether 8wk of discrete two-day intermittent fasting will impact gut microbiota and oxidative stress of Cardiovascular Diseases High-risk Subjects.
Type 2 diabetes mellitus, insulin resistance, visceral obesity and disorders of lipid metabolism, especially triglyceride and hypertension are metabolic disorders that play a central role in pathophysiology of metabolic syndrome, and ultimately, the cardiovascular morbidity and mortality associated with atherosclerosis, such as myocardial infarction, cerebral vascular events, vascular dementia, heart failure and end stage renal disease. Recently other complications related with...
This study aims to characterize the pathophysiological mechanisms of 21 different metabolic myopathies. The study will focus on exercise capacity and the metabolic derangement during exercise.
Postprandial lipemia is highly prevalent in type 2 diabetes subjects even with normal fasting triglyceride values. Humans are mostly in a postprandial rather than in a fasting state and therefore non-fasting triglyceride values reflect more accurately the continuous exposure of arterial wall to the substantial cholesterol load. Evolocumab lowers blood LDL-cholesterol. This study evaluates the effect of evolocumab on postprandial lipid metabolism in type 2 diabetes. All particip...
Alternate day fasting is known to be helpful to control weight and have a positive effect on insulin resistance and cardiovascular risk factors. However, there have been no studies on weight reduction program combining alternate day fasting with exercise which preserves lean mass in Korea. The purpose of this randomized clinical trial is to examine the effects of alternate day fasting and exercise on weight reduction, visceral fat, and metabolic parameters in overweight or obes...
This study will examine the potential changes in the blood levels of a recently discovered metabolic regulator in response to changes in diet in healthy adults. Our hypothesis is that in healthy adults key regulatory factors involved in lipid oxidation will respond to changes in diet, particularly fasting and diet-induced ketosis.
The purpose of this study will be to determine whether giving leptin (r-metHuLeptin) to a person when he or she is fasting will reverse changes in metabolism, and hormone levels, and immune function associated with fasting, which decreases leptin levels.
To evaluate the effects of flaxseed supplementation on fasting blood sugar, lipid profile and anthropocentric measurements in subjects with metabolic syndrome, in a randomized, open-labeled, controlled pilot study, 44 subjects with metabolic syndrome will be received 30g/d flaxseed with lifestyle modification or lifestyle modification alone for 12 weeks. Both groups will be advised to follow an energy balanced diet and physical activity recommendations. Parameters related to me...
Background: Calorie restriction increases longevity in many species and attenuate the development of chronic disorders including type 2 diabetes, cardiovascular diseases and cancer. In mice reduced activity of insulin-like growth factor I (IGF-I) and/or insulin is associated with extended longevity. Growth hormone (GH) is the main regulator of IGF-I production, but the molecular mechanism whereby GH switches from IGF-I stimulation (protein anabolism) to fatty acid oxidation (fa...
Evidence is accumulating that there are sex differences in energy and substrate metabolism. The positive or negative consequences of such metabolic differences between men and women need to be evaluated with respect to health outcomes. The importance of aberrant lipid metabolism in metabolic diseases such as obesity, diabetes and cardiovascular disease, makes understanding the distinction between "normal" vs aberrant critical to future treatment and prevention strategies. Sex d...
Accumulating evidence suggests that the natriuretic peptide (NP) hormonal system has important effects on metabolism. However, more information is needed to better understand the effects of NPs on metabolism in humans. Therefore, the investigators propose a study to determine the effects of b-type natriuretic peptide (BNP) on energy and fat metabolism in humans. The investigators' primary hypothesis is that the administration of BNP will increase energy expenditure in humans. T...
This study will explore differences in energy metabolism and metabolic flexibility under various conditions in older men and women.
In this study, the investigators wanted to investigate the energy homeostasis and the steroid metabolism of 20 healthy, young and normal weight women aged between 16-35 years before and after a 48 hours fasting period. The following substrates and hormone concentrations representing the carbohydrate, fat and protein metabolism will be measured from plasma or urine before and after fasting: glucose, insulin, lactate, alpha-synucleine, free fatty acids, beta-hydroxybutyrate (ket...
