Introduction: Fasting during the holy month of Ramadan is an obligation for all adult, healthy Muslims. As several studies have indicated, both fasting and energy restriction can alter thyroid hormone metabolism and affect the clinical features and well-being of hypothyroid patients. Hypothyroidism is more prevalent among women and the elderly. Its prevalence has been reported to be 4-8% of the...

background: fasting is an alternative method to induceanorexia. objectives: the biochemical factors of liver andserum and clinical signs were measured and documented in fivenon-lactating, non-pregnant cows following eight days of fasting.methods:five crossbred, non-lactating, and non-pregnantcattle were used in this study. they were fasted for 8 days_ totalfood deprivation; however, they had fr...

Background Optimal athletic performance is often linked to body composition, therefore depending on sport and position, a decrease in body fat would lean toward an increase in athletic fitness. A recent trend in decreasing body fat while maintaining muscle has emerged, called intermittent fasting. Some research has suggested that ingesting calories only in a certain time frame during the day (8...

OBJECTIVE Estrogen plays an important role in feeding and energy balance, and the critical role of estrogen in the control of appetite and energy balance is mediated by hypothalamic estrogen receptor (ER) alpha. In undernourished rodents, hypothalamic ER alpha mRNA expression are decreased. Responses of some hypothalamic factors to negative energy balance develop during the early neonatal perio...

Twelve adult Muzaffarnagari rams (mean weight 41.4 2.09) were used to study fasting heat production (FHP) using open circuit respiration calorimetry. After a maintenance level of feeding for 60, sheep were fasted for three days and later subjected to gaseous exchange studies for 72±96 h. Mean oxygen consumption, carbon dioxide and methane production (l/d) and urinary nitrogen excretion (g/d) va...

This study was conducted in the animal field that belongs to Animal Resource Dept.,College of Agriculture and Forestry,Mosul University. Sixteen local males lambs were used at the began of fasting process with age about 7-8 months and initial weight average 38.200 kg , were divided randomly into four groups and then distributed randomly into four treatments. The treatments consisted of differen...

The effects of rectal distension on upper gastrointestinal motility were investigated in six healthy subjects. On a control day, gastric and duodenal motor activity was recorded for nine hours of fasting and for four hours after a meal, duodeno-caecal transit being assessed in both interdigestive and digestive states. Motor activity and transit were also measured on a test day during which the ...

The effect of a "normal" (n = 8) and "high" (n = 6) protein intake (1 and 2.5 g x kg(-1) x day(-1), respectively) and of exercise on plasma amino acid (AA) concentrations, insulin, and glucagon concentrations was followed throughout a continuous 24-h period in adult male subjects at energy balance after six days on a standardized diet and exercise program. Subjects were fasting from 2100 on day...

Fasting heat production (FHP) is used for characterizing the basal metabolic rate of animals and the corresponding maintenance energy requirements and in the calculation of net energy value of feeds. In broilers, the most recent FHP estimates were obtained in the 1980s in slow-growing and fatter birds than nowadays. The FHP values (n=73; six experiments) measured in 3 to 6-week-old modern lines...
