Methods: A scoping review was undertaken to identify relevant articles that answered the research question: what are the similarities and differences in characteristics of time-restricted feeding and Islamic fasting?
MEDLINE/Pub Med was searched using the terms: time-restricted feeding, and weight.
Inclusion criteria were: original research and review articles; written in English; and published between the years 20.
Results: A total of 25 articles that answered the research question were included in the review: 15 original research papers and 10 reviews.
In Islamic fasting, Muslims refrain from consuming both food and water from sunrise to sunset.
Therefore, the duration of daily fasting varies according to the time from sunrise to sunset in a particular location.
In countries located near the equator, the duration of fasting is about 14 hours and the allowable feeding time is about 10 hours.
However, in countries further away from the equator, the duration of fasting varies according to the season – longer in summer (more than 20 hours) and shorter in winter (less than 8 hours) (7).
