Ramadan, which begins on May 6 for most countries this year, is the holiest month on the Islamic calendar.
This involves refraining from eating, drinking, smoking and having bad from dawn to sunset, in the hope that it will lead to greater " taqwa ", or consciousness of God.
Muslims were ordered to fast during Ramadan more than 1400 years ago. The ancient Greeks had recommended fasting to heal the body. Today, some scientists advocate a modified fast for its mental and physical benefits.
Known as intermittent fasting, this modified fasting comes in a number of forms that require not eating for 12, 16 or 24 hours at a time. Another form, called the fast 5: 2, advocates a caloric restriction (consuming only between 500 and 600 calories) over a 36-hour period, twice a week.
Eat Stop Eat, a book by Brad Pilon published in 2007, recommended to abstain from eating for 24 hours once or twice a week, leaving individuals free to decide when to start and end their fasting.
In 2012, Michael Mosley released his television documentary Eat, Fast and Live Longer and his best-seller The Fast Diet, both based on the 5: 2 concept of intermittent fasting.
"In The Fast Diet, I advocate a form of fasting called" time-restricted consumption, "Mosley told Al Jazeera.
"It means eating only during certain hours, like the fasting practiced by Muslims during Ramadan.
"The proven benefits include improved sleep and evidence of reduced risk of certain cancers, especially bad cancer."

Scientists have also studied the link between diet, intestinal health and mental well-being and, as Mosley explained to Al Jazeera, fasting can lead to the release of BDNF (brain-derived neurotrophic factor) in the body. brain.
"It has been proven that it protects brain cells and can reduce depression and anxiety, as well as the risk of developing dementia," Mosley said.

When not to fast
As with any change of diet or lifestyle, fasting involves risks because it is not suitable for everyone.
People whose health condition is compromised or who are followed by a doctor for any health problem should consult a doctor before trying to monitor some of the side effects.
"Fasting can lead to low blood sugar, which leads to lower concentration and increased fatigue," said Nazmin Islam, a registered nutritionist.
Islam added that a lasting weight loss was only possible with a regular fast and that any weight loss during Ramadan could easily be reversed once the individual had resumed his / her daily eating habits.
"However, the benefits outweigh the disadvantages: in the long run, fasting, if done properly, can improve the digestive system and metabolism in general."
