Abstract
Purpose
The purpose of this article is to assess the effect of religious fasting on the cognitive performance during the month of Ramadan among healthy fasting individuals.
Design/methodology/approach
30 students were recruited prior the month of Ramadan to compare their cognitive performance during and after fasting. The data on cognition score were collected in two phases during and after Ramadan on four occasions (two times in Ramadan and two times after Ramadan) using structured questionnaire. The level of cognition was assessed by using two approaches: mathematical problem solving and memory testing. Five questions of mathematical problem were given to the subjects and were different at each week. However, the level of difficulty was kept constant. The time and score were recorded for each respondent during and after fasting month. For the memory test, ten pictures of items of similar sizes were displayed for 30 seconds, and the subjects were asked to recall/list down the item shown in the pictures. The cognition scores were expressed as mean±SD, and repeated measures analysis test was used for differences in fasting and non‐fasting days.
Findings
As expected, during Ramadan meal frequency was lower and sleeping (nap) frequency was higher with shorter duration at night. The feeling of tiredness was higher compared to non‐fasting days. The level of cognition score for was not different during Ramadan compared to non‐fasting days. The result shows that the level of cognition is not affected in fasting.
Originality/value
The research shows that the cognition is not affected in Ramadan fasting.

Abstract
Purpose
This study was designed with the aim of assessing the energy and nutrient intakes of male university students before and during Ramadan and comparing it with the Recommended Nutrient Intake (RNI) of Malaysia.
Design/methodology/approach
A total of 30 male students aged between 19‐24 years from International Islamic University Malaysia (IIUM) Kuantan Campus were recruited before Ramadan. The height, weight, waist and hip circumferences were recorded on day one of Ramadan and also recorded on day 21 of Ramadan to assess the changes. From the weight and height, the body mass index was calculated and from the waist and hip circumference, the waist‐to‐hip ratios were calculated. The respondents were requested to keep three days food record in household measurements; once prior to fasting and once during the third week of Ramadan. The records were then analyzed using Malaysian Food Composition Table and Food Atlas to get the averages of energy and macronutrients intakes of the subjects.
Findings
After 21 days of Ramadan, the results revealed that there was reduction in the body weight and there was significant (P<0.05) improvement in the waist‐to‐hip ratio of the subjects. The effect was more prominent in the normal‐weight compared to overweight respondents. The mean energy and protein intakes were significantly (P<0.001) lower than the RNI for Malaysians of similar age group. However, mean energy and protein intakes increased during Ramadan compared to the first day of Ramadan. This study indicates that Ramadan fasting does not affect energy and macronutrients intake but only the routine of intake is affected.
Research limitations/implications
This research was limited to a specific group of normal and overweight students who were residing on campus of the IIUM. Their intakes might not be consistent with those at home or living outside the university campus. Another thing is that the students might have over‐reported their energy and macro‐nutrients intakes compared to what they have consumed in reality. So, the self‐reported intakes could not be ascertained. The stated factors might have confounding effects on the finding of this research.
Practical implications
Most research argues that the body weight loss during Ramadan fasting is due to reduced energy consumption; however, this is not true in all cases. This study infers that there is no reduction in the total energy consumption, rather there is a change in the pattern of energy intake. This brief study would help researchers planning to conduct research on Ramadan fasting and will caution fasting readers about the intakes.
Originality/value
This study indicates that during Ramadan fasting does not affect energy and macro‐nutrients intake but only the schedule of intake is affected.
