“…Eating such particular types of food at inappropriate times may be a factor in gastro-intestinal complaints and predisposes individuals to becoming overweight [11]. A significant correlation between the number of calories ingested during a meal and the duration of subsequent sleep has been reported in rats [12] but the relationship is less clear in humans. Similarly, eating at night after a day-time fast can disrupt sleep due to intestinal discomfort from eating too much or as sequel to hunger from having eaten too little earlier on [11].…”

“…e SWA is a valid, reliable, portable, practical and easily accessible device that reports total and active EE, METs values, duration and quanti cation of physical activity, body position, sleep e ciency, and sleep duration. Furthermore, the SWA relies more on subject characteristics, such as age, gender and weight, to calculate the resting metabolic rate, and it is not sensitive to small changes in EE from day to day [13,25]. Modulation of the resting EE by thyroid hormones is well recognized in humans and rodents [2,26].…”

Purpose: e aim of the present study was to evaluate the average sleeping energy expenditure (EE) levels using the SenseWear Armband (SWA) in patients with overt and subclinical hypothyroidism.Methods: Sixty patients with hypothyroidism and 30 healthy individuals were recruited for the study. Hypothyroid patients were divided into two groups: group 1 (n = 30) consisted of patients with overt hypothyroidism and group 2 (n = 30) consisted of patients with subclinical hypothyroidism. Lastly, group 3 (n = 30) consisted of healthy subjects.e average EE and metabolic equivalent of task (MET) values during sleep of all the hypothyroid participants were analyzed at baseline and at the end of the study. Data were also obtained from the healthy subjects at baseline.Results: e average sleeping EE and METs values were not signi cantly di erent at baseline. Similarly, these values did not change signi cantly a er achieving a euthyroid state via thyroid hormone replacement (both p > 0.05). Conclusions:Contrary to what has been previously reported , the average sleeping EE and METs values in all hypothyroid patients and healthy individuals were similar at baseline and did not change in the patients with overt and subclinical hypothyroidism a er achievement of a euthyroid state.

“…The duration of this ritual of worshipping is 1 month every year and involves the limitation of food and liquid intake between sunrise and sunset [2,3]. Since the Islamic calendar is a lunar calendar and it is 10 days shorter than a solar calendar, the month of Ramadan arrives 10 days earlier every year.…”

Abstract:Objective: Our aim was to determine how Ramadan fasting eff ects serum Human NAD-dependent deacetylase sirtuin 1 (SIRT1/ SIR2L1) and visfatin levels during pregnancy. Materials and methods: Thirty-six patients were included in this case-control study. The patient group consisted of 18 pregnant women who were Ramadan fasting. Another healthy 18 pregnant women with matching pregnancy weeks and ages formed the control group. Blood samples were obtained from the patients for biochemical analyses and serum adipokine level measurements. Results: The mean sirtuin and visfatin levels in fasting pregnant women were 2.87 ± 0.95 and 60.18 ± 19.49 ng/mL, respectively, while the mean serum sirtuin and visfatin levels in the control group was determined to be 4.28 ± 1.45 and 23.26 ± 6.18 ng/mL, respectively. A statistically signifi cant diff erence was determined between the groups (p = 0.002, p = 0.0001). A correlation analysis provided a negative correlation between number of fasting days and sirtuin levels (r = 0.45, p = 0.005) and a positive correlation with visfatin levels (r = 0.73, p = 0.0001). Conclusion: As a result, while the serum sirtuin 1 level of pregnant women decreased due to fasting in Ramadan, we determined that their visfatin levels increased and this increase was in correlation with the days of fasting.
