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… Read More

Periods of deliberate fasting with restriction of solid food intake are practiced worldwide, mostly based on traditional, cultural or religious reasons. There is large empirical and observational evidence that medically supervised modified fasting (fasting cure, 200-500 kcal nutritional intake per day) with periods of 7-21 days is efficacious in the treatment of rheumatic diseases, chronic… Read More

BACKGROUND AND AIM: Weight loss improves the metabolic syndrome (MetS) features and related clinical abnormalities in obese subjects. The aim of this study was to assess the effects of a non-surgical therapeutic program on the MetS in severely obese patients. PATIENTS AND METHODS: Sixty-four extremely obese patients were involved in the therapeutic program, which consisted of two alternating… Read More

Human biomonitoring studies measuring bisphenol A (BPA) in urine have shown widespread exposure in the general population. Diet is thought to be a major route of exposure. We studied urinary BPA patterns in five individuals over a 48-h period of fasting (bottled water only). Personal activity patterns were recorded with a diary to investigate non-dietary routes of exposure.… Read More

Starvation may change autonomic nervous system activity and sensitivity such that a greater vagal withdrawal may occur during a sympathetic challenge. Six healthy humans endured a 3-day, water-only fast, during which participants were subjected to passive 80 degrees head-up tilt testing twice on each day (a.m. and p.m.). Heart rate, heart rate variability (HRV), ventilation [Formula: see text… Read More

INTRODUCTION: Dietary restriction benefits health and increases lifespan in several species. Food odorants restrain the beneficial effects of dietary restriction in Drosophila melanogaster. We hypothesized that the presence of visual and odorous food stimuli during a prolonged fast modifies the neuroendocrine and metabolic response to fasting in humans. SUBJECTS AND METHODS: In this randomized… Read More

BACKGROUND: Appendicitis is an acute condition of the abdomen that is treated with surgical intervention. Conservative treatment of appendicitis currently involves intravenous antibiotics. While conservative care is a useful tool in apprehensive patients, in conditions such as appendicitis, delays in proper treatment can be life threatening. In spite of this, some… Read More

Short-term fasting (48 hours) was shown to be effective in protecting normal cells and mice but not cancer cells against high dose chemotherapy, termed Differential Stress Resistance (DSR), but the feasibility and effect of fasting in cancer patients undergoing chemotherapy is unknown. Here we describe 10 cases in which patients diagnosed with a variety of… Read More
