BACKGROUND 5-HT(3) antagonists have been shown to be effective in relieving the symptoms of irritable bowel syndrome with diarrhoea (IBS-D). Using a recently validated magnetic resonance imaging (MRI) method, we have demonstrated reduced fasting small bowel water content (SBWC) in IBS-D associated with accelerated small bowel transit. We hypothesized that slowing of transit with ondansetron wou...

Introduction: Obesity is a complex health problem. The aim of this study was to determine the effects of regular walking with alternate day fasting (ADF) on health-related factors of overweight and obese females.‎  Methods: 30 healthy inactive, overweight and obese women were divided randomly into three equal groups.  The groups were: control group (BMI: 30.72±4.40 kg/m2); the experimental grou...

Over centuries, mankind had to deal with a steadily changing food supply. Depending on seasonal fluctuations or greater natural disasters, either plenty or little food was available. As a consequence, people in different areas of the world developed sophisticated strategies, e.g., seasonal fasting, to handle and overcome these problems. Possibly, in these early days, people discovered also the ...

Clinicians have found that fasting was frequently accompanied by an increased level of vigilance and a mood improvement, a subjective feeling of well-being, and sometimes of euphoria. Therapeutic fasting, following an established protocol, is safe and well tolerated. We aim in this article to explore the biological mechanisms activated during fasting that could have an effect on brain function ...

The purpose of this work was to investigate the effect of fasting on the induction and growth of chemically-induced mammary carcinogenesis. Female Sprague-Dawley rats were given methylnitrosourea (MNU) i.p. (50 mg/kg) at 50 days of age; a group of rats were exposed to 4 day fasting followed by 1 day of refeeding before the administration of the carcinogen, while another group was exposed to thr...

Many animals lower their resting metabolism (metabolic depression) when fasting or consuming inadequate food. We sought to document this response by subjecting five Steller sea lions to periods of: (1) complete fasting; or (2) restricting them to 50% of their normal herring diet. The sea lions lost an average of 1.5% of their initial body mass per day (2.30 kg/d) during the 9-14-day fast, and t...

During kidney transplantation, ischemia-reperfusion injury (IRI) induces oxidative stress. Short-term preoperative 30% dietary restriction (DR) and 3-day fasting protect against renal IRI. We investigated the contribution of macronutrients to this protection on both phenotypical and transcriptional levels. Male C57BL/6 mice were fed control food ad libitum, underwent two weeks of 30%DR, 3-day f...

ost healthy adults in Muslim communities practice fasting during the holy month of Ramadan. This kind of fasting involves daily abstinence from food and water, from sunrise to sunset, a period that lasts approximately 12 to 17 hours, depending on the season and geographical latitude. Ramadan is a lunar month, which lasts 28 to 30 days and its length changes along the solar year. Ramadan fasting...

The objective was to investigate the effect of intake before fasting on concentrations of metabolites and hormones, respiratory quotient (RQ) and fasting heat production (HP) using the washed rumen technique and to compare these values with those from the fed state. Six Holstein steers (360±22 kg) were maintained at 21°C and fed three different energy intakes within a replicated 3×3 Latin squar...
