Fasting and metabolic health الصيام

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ كُتِبَ عَلَيۡكُمُ ٱلصِّيَامُ كَمَا كُتِبَ عَلَى ٱلَّذِينَ مِن قَبۡلِكُمۡ لَعَلَّكُمۡ تَتَّقُونَ

You who believe, fasting is prescribed for you, as it was prescribed for those before you, so that you may be mindful of God

أُحِلَّ لَكُمۡ لَيۡلَةَ ٱلصِّيَامِ ٱلرَّفَثُ إِلَىٰ نِسَآئِكُمۡۚ هُنَّ لِبَاسࣱ لَّكُمۡ وَأَنتُمۡ لِبَاسࣱ لَّهُنَّۗ عَلِمَ ٱللَّهُ أَنَّكُمۡ كُنتُمۡ تَخۡتَانُونَ أَنفُسَكُمۡ فَتَابَ عَلَيۡكُمۡ وَعَفَا عَنكُمۡۖ فَٱلۡـَٰٔنَ بَٰشِرُوهُنَّ وَٱبۡتَغُواْ مَا كَتَبَ ٱللَّهُ لَكُمۡۚ وَكُلُواْ وَٱشۡرَبُواْ حَتَّىٰ يَتَبَيَّنَ لَكُمُ ٱلۡخَيۡطُ ٱلۡأَبۡيَضُ مِنَ ٱلۡخَيۡطِ ٱلۡأَسۡوَدِ مِنَ ٱلۡفَجۡرِۖ ثُمَّ أَتِمُّواْ ٱلصِّيَامَ إِلَى ٱلَّيۡلِۚ وَلَا تُبَٰشِرُوهُنَّ وَأَنتُمۡ عَٰكِفُونَ فِي ٱلۡمَسَٰجِدِۗ تِلۡكَ حُدُودُ ٱللَّهِ فَلَا تَقۡرَبُوهَاۗ كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ ءَايَٰتِهِۦ لِلنَّاسِ لَعَلَّهُمۡ يَتَّقُونَ

You [believers] are permitted to lie with your wives during the night of the fast: they are [close] as garments to you, as you are to them. God was aware that you were betraying yourselves, so He turned to you in mercy and pardoned you: now you can lie with them- seek what God has ordained for you- eat and drink until the white thread of dawn becomes distinct from the black. Then fast until nightfall. Do not lie with them during the nights of your devotional retreat in the mosques: these are the bounds set by God, so do not go near them. In this way God makes His messages clear to people, that they may guard themselves against doing wrong

وَأَتِمُّواْ ٱلۡحَجَّ وَٱلۡعُمۡرَةَ لِلَّهِۚ فَإِنۡ أُحۡصِرۡتُمۡ فَمَا ٱسۡتَيۡسَرَ مِنَ ٱلۡهَدۡيِۖ وَلَا تَحۡلِقُواْ رُءُوسَكُمۡ حَتَّىٰ يَبۡلُغَ ٱلۡهَدۡيُ مَحِلَّهُۥۚ فَمَن كَانَ مِنكُم مَّرِيضًا أَوۡ بِهِۦٓ أَذࣰ ى مِّن رَّأۡسِهِۦ فَفِدۡيَةࣱ مِّن صِيَامٍ أَوۡ صَدَقَةٍ أَوۡ نُسُكࣲۚ فَإِذَآ أَمِنتُمۡ فَمَن تَمَتَّعَ بِٱلۡعُمۡرَةِ إِلَى ٱلۡحَجِّ فَمَا ٱسۡتَيۡسَرَ مِنَ ٱلۡهَدۡيِۚ فَمَن لَّمۡ يَجِدۡ فَصِيَامُ ثَلَٰثَةِ أَيَّامࣲ فِي ٱلۡحَجِّ وَسَبۡعَةٍ إِذَا رَجَعۡتُمۡۗ تِلۡكَ عَشَرَةࣱ كَامِلَةࣱۗ ذَٰلِكَ لِمَن لَّمۡ يَكُنۡ أَهۡلُهُۥ حَاضِرِي ٱلۡمَسۡجِدِ ٱلۡحَرَامِۚ وَٱتَّقُواْ ٱللَّهَ وَٱعۡلَمُوٓاْ أَنَّ ٱللَّهَ شَدِيدُ ٱلۡعِقَابِ

Complete the pilgrimages, major and minor, for the sake of God. If you are prevented [from doing so], then [send] whatever offering for sacrifice you can afford, and do not shave your headsuntil the offering has reached the place of sacrifice. If any of you is ill, or has an ailment of the scalp, he should compensate by fasting, or feeding the poor, or offering sacrifice. When you are in safety, anyone wishing to take a break between the minor pilgrimage and the major one must make whatever offering he can afford. If he lacks the means, he should fast for three days during the pilgrimage, and seven days on his return, making ten days in all. This applies to those whose household is not near the Sacred Mosque. Always be mindful of God, and be aware that He is stern in His retribution

وَمَا كَانَ لِمُؤۡمِنٍ أَن يَقۡتُلَ مُؤۡمِنًا إِلَّا خَطَـࣰٔ اۚ وَمَن قَتَلَ مُؤۡمِنًا خَطَـࣰٔ ا فَتَحۡرِيرُ رَقَبَةࣲ مُّؤۡمِنَةࣲ وَدِيَةࣱ مُّسَلَّمَةٌ إِلَىٰٓ أَهۡلِهِۦٓ إِلَّآ أَن يَصَّدَّقُواْۚ فَإِن كَانَ مِن قَوۡمٍ عَدُوࣲّ لَّكُمۡ وَهُوَ مُؤۡمِنࣱ فَتَحۡرِيرُ رَقَبَةࣲ مُّؤۡمِنَةࣲۖ وَإِن كَانَ مِن قَوۡمِۭ بَيۡنَكُمۡ وَبَيۡنَهُم مِّيثَٰقࣱ فَدِيَةࣱ مُّسَلَّمَةٌ إِلَىٰٓ أَهۡلِهِۦ وَتَحۡرِيرُ رَقَبَةࣲ مُّؤۡمِنَةࣲۖ فَمَن لَّمۡ يَجِدۡ فَصِيَامُ شَهۡرَيۡنِ مُتَتَابِعَيۡنِ تَوۡبَةࣰ مِّنَ ٱللَّهِۗ وَكَانَ ٱللَّهُ عَلِيمًا حَكِيمࣰ ا

Never should a believer kill another believer, except by mistake. If anyone kills a believer by mistake he must free one Muslim slave and pay compensation to the victim’s relatives, unless they charitably forgo it; if the victim belonged to a people at war with you but is a believer, then the compensation is only to free a believing slave; if he belonged to a people with whom you have a treaty, then compensation should be handed over to his relatives, and a believing slave set free. Anyone who lacks the means to do this must fast for two consecutive months by way of repentance to God: God is all knowing, all wise

لَا يُؤَاخِذُكُمُ ٱللَّهُ بِٱللَّغۡوِ فِيٓ أَيۡمَٰنِكُمۡ وَلَٰكِن يُؤَاخِذُكُم بِمَا عَقَّدتُّمُ ٱلۡأَيۡمَٰنَۖ فَكَفَّٰرَتُهُۥٓ إِطۡعَامُ عَشَرَةِ مَسَٰكِينَ مِنۡ أَوۡسَطِ مَا تُطۡعِمُونَ أَهۡلِيكُمۡ أَوۡ كِسۡوَتُهُمۡ أَوۡ تَحۡرِيرُ رَقَبَةࣲۖ فَمَن لَّمۡ يَجِدۡ فَصِيَامُ ثَلَٰثَةِ أَيَّامࣲۚ ذَٰلِكَ كَفَّٰرَةُ أَيۡمَٰنِكُمۡ إِذَا حَلَفۡتُمۡۚ وَٱحۡفَظُوٓاْ أَيۡمَٰنَكُمۡۚ كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ لَكُمۡ ءَايَٰتِهِۦ لَعَلَّكُمۡ تَشۡكُرُونَ

God does not take you [to task] for what is thoughtless in your oaths, only for your binding oaths: the atonement for breaking an oath is to feed ten poor people with food equivalent to what you would normally give your own families, or to clothe them, or to set free a slave- if a person cannot find the means, he should fast for three days. This is the atonement for breaking your oaths- keep your oaths. In this way God makes clear His revelations to you, so that you may be thankful

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَقۡتُلُواْ ٱلصَّيۡدَ وَأَنتُمۡ حُرُمࣱۚ وَمَن قَتَلَهُۥ مِنكُم مُّتَعَمِّدࣰ ا فَجَزَآءࣱ مِّثۡلُ مَا قَتَلَ مِنَ ٱلنَّعَمِ يَحۡكُمُ بِهِۦ ذَوَا عَدۡلࣲ مِّنكُمۡ هَدۡيَۢا بَٰلِغَ ٱلۡكَعۡبَةِ أَوۡ كَفَّٰرَةࣱ طَعَامُ مَسَٰكِينَ أَوۡ عَدۡلُ ذَٰلِكَ صِيَامࣰ ا لِّيَذُوقَ وَبَالَ أَمۡرِهِۦۗ عَفَا ٱللَّهُ عَمَّا سَلَفَۚ وَمَنۡ عَادَ فَيَنتَقِمُ ٱللَّهُ مِنۡهُۚ وَٱللَّهُ عَزِيزࣱ ذُو ٱنتِقَامٍ

You who believe, do not kill game while you are in the state of consecration [for pilgrimage]. If someone does so intentionally the penalty is an offering of a domestic animal brought to the Kaba, equivalent- as judged by two just men among you- to the one he has killed; alternatively, he may atone by feeding the needy or by fasting an equivalent number of days, so that he may taste the full gravity of his deed. God forgives what is past, but if anyone re-offends, God will exact the penalty from him: God is mighty, and capable of exacting the penalty

O you who have faith! Written for you is fasting. In the tongue of allusion and the clarification of wisdom, He is saying, “O you who have faith, fasting has been written for you. It has been written because you will be the guests of the Real, and tomorrow in paradise He wants to take hungry guests to a banquet. When the generous take someone to a banquet, they like the guests to be hungry so that the feast will be sweeter in their hearts. The Lord of the Worlds created paradise and everything within it for the faithful. None of it is of any use to Him, nor does He have any need for it.” A pir of the Sufis sent out an invitation, but no one came. The pir lifted up his hands and said, “Lord God, if you send your servants into the fire tomorrow, paradise and perfect bliss will be like my table!” The value of a table is for people to sit there and eat. Indeed, the Lord of the Worlds created

(It is made lawful for you to go in unto your wives on the night of the fast...) [2:187]. According to the report of al-Walibi, Ibn �Abbas said: �This is because after the nightfall (�Isha�) prayer during Ramadan, the Muslims were forbidden to have food or sex until the following night. But some Muslims, among whom were �Umar ibn al-Khattab, complained to Allah�s Messenger, Allah bless him and give him peace, about this. And so Allah, exalted is He, revealed this verse�. Abu Bakr al-Asfahani informed us> Abu�l-Shaykh al-Hafiz> �Abd al-Rahman ibn Muhammad al-Razi> Sahl ibn �Uthman al-�Askari> Yahya ibn Abi Za�idah> his father and others> Abu Ishaq> al-Bara� ibn �Azib who said: �After breaking their fast, the Muslims used to be allowed to eat, drink and have sexual intercourse for as long as they did not sleep. Once they went to sleep, they were forbidden to do all these things until the f

O you who believe prescribed for you obligatory for you is the Fast just as it was prescribed for those communities that were before you so that you might guard yourselves against acts of disobedience for it the fast curbs the desires that prompt these acts.

Permitted to you upon the night of the Fast is to go in to your wives in sexual intercourse this was revealed as an abrogation of its unlawfulness during the earliest phase of Islam as well as an abrogation of the unlawfulness of eating and drinking after the night prayer; they are a vestment for you and you are a vestment for them a metaphor for their embraces or their need for one another; God knows that you have been betraying yourselves by having sexual intercourse on the eve of the fast this happened with ‘Umar b. al-Khattāb and others and they apologised to the Prophet s and so He has turned to you relenting before you even turned in repentance and He has pardoned you. So now when it is permitted to you lie with them in sexual intercourse and seek what God has prescribed for you of sexual intercourse or what it produces of offspring; and eat and drink at any time during the night u

And complete the hajj and the umrah for God. It is narrated from Wahab ibn Munabbih that God sent a revelation to Adam: “O Adam, I am the Lord of the world and the world's folk, the creator of all, the king doing what I desire. I am the Lord of Bakka, and those who dwell there are My neighbors. Those who visit are My delegates, My guests, and under My protection. I will populate this spot with the folk of heaven and earth. They will come in droves from every direction and every region, their hair disheveled and their faces covered with dust from the suffering of the road, saying 'God is greater' and reciting 'Here I am,' their faces turned toward the blessed desert, the earth colored with the blood of sacrifice. “O Adam! When someone visits this house and is self-purifying in that, he is My guest and one of Mine, one of those near to Me. It is worthy of My majesty to honor him and to bri

(It is not for a believer to kill a believer unless (it be) by mistake�) [4:92]. Abu �Abd Allah ibn Abi Ishaq informed us> Abu �Amr ibn Nujayd> Abu Muslim Ibrahim ibn �Abd Allah> Ibn Hajjaj> Hammad> Muhammad ibn Ishaq> �Abd al-Rahman ibn al-Qasim> his father who reported that al-Harith ibn Shadid was hard on the Prophet, Allah bless him and give him peace. He was on his way to embrace Islam when he was met by �Ayyash ibn Abi Rabi�ah, and not realising that al-Harith wanted to embrace Islam, he killed him. And so Allah, exalted is He, revealed this verse (It is not for a believer to kill a believer unless (it be) by mistake�). Al-Kalbi explained this event, saying: ��Ayyash ibn Abi Rabi�ah al-Makhzumi had embraced Islam but was fearful of coming in the open about it. He fled to Medina and took refuge in one of its fortresses. His mother was distressed a great deal. She said to her two son

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، أَخْبَرَنَا مَالِكٌ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ رِجَالاً، مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم أُرُوا لَيْلَةَ الْقَدْرِ فِي الْمَنَامِ فِي السَّبْعِ الأَوَاخِرِ، فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ أَرَى رُؤْيَاكُمْ قَدْ تَوَاطَأَتْ فِي السَّبْعِ الأَوَاخِرِ، فَمَنْ كَانَ مُتَحَرِّيَهَا فَلْيَتَحَرَّهَا فِي السَّبْعِ الأَوَاخِرِ ‏"‏‏.‏

Narrated Ibn `Umar:Some men amongst the companions of the Prophet (ﷺ) were shown in their dreams that the night of Qadr was in the last seven nights of Ramadan. Allah's Messenger (ﷺ) said, "It seems that all your dreams agree that (the Night of Qadr) is in the last seven nights, and whoever wants to search for it (i.e. the Night of Qadr) should search in the last seven (nights of Ramadan)

حَدَّثَنَا إِبْرَاهِيمُ بْنُ حَمْزَةَ، قَالَ حَدَّثَنِي ابْنُ أَبِي حَازِمٍ، وَالدَّرَاوَرْدِيُّ، عَنْ يَزِيدَ، عَنْ مُحَمَّدِ بْنِ إِبْرَاهِيمَ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ـ رضى الله عنه ـ‏.‏ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُجَاوِرُ فِي رَمَضَانَ الْعَشْرَ الَّتِي فِي وَسَطِ الشَّهْرِ، فَإِذَا كَانَ حِينَ يُمْسِي مِنْ عِشْرِينَ لَيْلَةً تَمْضِي، وَيَسْتَقْبِلُ إِحْدَى وَعِشْرِينَ، رَجَعَ إِلَى مَسْكَنِهِ وَرَجَعَ مَنْ كَانَ يُجَاوِرُ مَعَهُ‏.‏ وَأَنَّهُ أَقَامَ فِي شَهْرٍ جَاوَرَ فِيهِ اللَّيْلَةَ الَّتِي كَانَ يَرْجِعُ فِيهَا، فَخَطَبَ النَّاسَ، فَأَمَرَهُمْ مَا شَاءَ اللَّهُ، ثُمَّ قَالَ ‏ "‏ كُنْتُ أُجَاوِرُ هَذِهِ الْعَشْرَ، ثُمَّ قَدْ بَدَا لِي أَنْ أُجَاوِرَ هَذِهِ الْعَشْرَ الأَوَاخِرَ، فَمَنْ كَانَ اعْتَكَفَ مَعِي فَلْيَثْبُتْ فِي مُعْتَكَفِهِ، وَقَدْ أُرِيتُ هَذِهِ اللَّيْلَةَ ثُمَّ أُنْسِيتُهَا فَابْتَغُوهَا فِي الْعَشْرِ الأَوَاخِرِ وَابْتَغُوهَا فِي كُلِّ وِتْرٍ، وَقَدْ رَأَيْتُنِي أَسْجُدُ فِي مَاءٍ وَطِينٍ ‏"‏‏.‏ فَاسْتَهَلَّتِ السَّمَاءُ فِي تِلْكَ اللَّيْلَةِ، فَأَمْطَرَتْ، فَوَكَفَ الْمَسْجِدُ فِي مُصَلَّى النَّبِيِّ صلى الله عليه وسلم لَيْلَةَ إِحْدَى وَعِشْرِينَ، فَبَصُرَتْ عَيْنِي رَسُولَ اللَّهِ صلى الله عليه وسلم وَنَظَرْتُ إِلَيْهِ انْصَرَفَ مِنَ الصُّبْحِ، وَوَجْهُهُ مُمْتَلِئٌ طِينًا وَمَاءً‏.‏

Narrated Abu Sa`id Al-Khudri:Allah's Messenger (ﷺ) used to practice I`tikaf (in the mosque) in the middle third of Ramadan and after passing the twenty nights he used to go back to his house on the 21st, and the people who were in I`tikaf with him also used to go back to their houses. Once in Ramadan, in which he practiced I`tikaf, he established the night prayers at the night in which he used to return home, and then he addressed the people and ordered them whatever Allah wished him to order and said, "I used to practice I`tikaf for these ten days (i.e. the middle third but now I intend to stay in I`tikaf for the last ten days (of the month); so whoever was in I`tikaf with me should stay at his place of seclusion. I have verily been shown (the date of) this Night (of Qadr) but I have forgotten it. So search for it in the odd nights of the last ten days (of this month). I also saw myself (in the dream) prostrating in mud and water." On the night of the 21st, the sky was covered with clouds and it rained, and the rainwater started leaking through the roof of the mosque at the praying place of the Prophet (ﷺ) . I saw with my own eyes the Prophet at the completion of the morning prayer leaving with his face covered with mud and water

This hadith has been reported through another chain of transmitters, and there it is mentioned that. 'A'isha, Hafsa and Zainab (Allah be pleased with them) pitched the tents for i'tikaf

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا أَبُو مُعَاوِيَةَ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ عَمْرَةَ، عَنْ عَائِشَةَ، - رضى الله عنها - قَالَتْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا أَرَادَ أَنْ يَعْتَكِفَ صَلَّى الْفَجْرَ ثُمَّ دَخَلَ مُعْتَكَفَهُ وَإِنَّهُ أَمَرَ بِخِبَائِهِ فَضُرِبَ أَرَادَ الاِعْتِكَافَ فِي الْعَشْرِ الأَوَاخِرِ مِنْ رَمَضَانَ فَأَمَرَتْ زَيْنَبُ بِخِبَائِهَا فَضُرِبَ وَأَمَرَ غَيْرُهَا مِنْ أَزْوَاجِ النَّبِيِّ صلى الله عليه وسلم بِخِبَائِهِ فَضُرِبَ فَلَمَّا صَلَّى رَسُولُ اللَّهِ صلى الله عليه وسلم الْفَجْرَ نَظَرَ فَإِذَا الأَخْبِيَةُ فَقَالَ ‏ "‏ آلْبِرَّ تُرِدْنَ ‏"‏ ‏.‏ فَأَمَرَ بِخِبَائِهِ فَقُوِّضَ وَتَرَكَ الاِعْتِكَافَ فِي شَهْرِ رَمَضَانَ حَتَّى اعْتَكَفَ فِي الْعَشْرِ الأَوَّلِ مِنْ شَوَّالٍ ‏.‏

A'isha (Allah be pleased with her) reported that when the Messenger of Allah (ﷺ) decided to observe i'tikaf, he prayed in the morning and then went to the place of his i'tikaf, and he commanded that a tent should be pitched for him, and it was pitched. He (once) decided to observe i'tikaf in the last ten days of Ramadan. Zainab (the wife of the Holy Prophet) commanded that a tent should be pitched for her. It was pitched accordingly. And some other wives of Allah's Apostle (ﷺ) commanded that tents should be pitched for them too. And they were pitched. When the Messenger of Allah (may peace he upon him) offered the morning prayer, he looked and found (so many) tents. Thereupon he said:What is this virtue that these (ladies) have decided to acquire? He commanded his tent to be struck and abandoned i'tikaf in the month of Ramadan and postponed it to the first ten days of Shawwal

Abu Hurairah narrated that :the Messenger of Allah said: "On the first night of the month of Ramadan, the Shayatin are shackled, the jinns are restrained, the gates of the Fires are shut such that no gate among them would be opened. The gates of Paradise are opened such that no gate among them would be closed, and a caller calls: 'O seeker of the good; come near!' and 'O seeker of evil; stop! For there are those whom Allah frees from the Fire.' And that is every night

ومن آدابه: أن لا يمتلئ من الطعام فى الليل، بل يأكل بمقدار، فانه ما ملأ ابن آدم وعاء شرا من بطن. ومتى شبع أول الليل لم ينتفع بنفسه فى باقيه، وكذلك إذا شبع وقت السحر لم ينتفع بنفسه إلى قريب من الظهر، لأن كثرة الأكل تورث الكسل والفتور، ثم يفوت المقصود من الصيام بكثرة الأكل، لأن المراد منه أن يذوق طعم الجوع، ويكون تاركا للمشتهى.

Effects of a quercetin-rich onion skin extract on 24 h ambulatory blood pressure and endothelial function in overweight-to-obese patients with (pre-)hypertension: a randomised double-blinded placebo-controlled cross-over trial.

The polyphenol quercetin may prevent CVD due to its antihypertensive and vasorelaxant properties. We investigated the effects of quercetin after regular intake on blood pressure (BP) in overweight-to-obese patients with pre-hypertension and stage I hypertension. In addition, the potential mechanisms responsible for the hypothesised effect of quercetin on BP were explored. Subjects (n 70) were randomised to receive 162 mg/d quercetin from onion skin extract powder or placebo in a double-blinded, placebo-controlled cross-over trial with 6-week treatment periods separated by a 6-week washout period. Before and after the intervention, ambulatory blood pressure (ABP) and office BP were measured; urine and blood samples were collected; and endothelial function was measured by EndoPAT technology. In the total group, quercetin did not significantly affect 24 h ABP parameters and office BP. In th…

Central insulin administration improves whole-body insulin sensitivity via hypothalamus and parasympathetic outputs in men.

Animal studies suggest that insulin action in the brain is involved in the regulation of peripheral insulin sensitivity. Whether this holds true in humans is unknown. Using intranasal application of insulin to the human brain, we studied the impacts of brain insulin action on whole-body insulin sensitivity and the mechanisms involved in this process. Insulin sensitivity was assessed by hyperinsulinemic-euglycemic glucose clamp before and after intranasal application of insulin and placebo in randomized order in lean and obese men. After insulin spray application in lean subjects, a higher glucose infusion rate was necessary to maintain euglycemia compared with placebo. Accordingly, clamp-derived insulin sensitivity index improved after insulin spray. In obese subjects, this insulin-sensitizing effect could not be detected. Change in the high-frequency band of heart rate variability, an e…

Brain-Gut-Microbiome Interactions and Intermittent Fasting in Obesity.

The obesity epidemic and its metabolic consequences are a major public health problem both in the USA and globally. While the underlying causes are multifactorial, dysregulations within the brain-gut-microbiome (BGM) system play a central role. Normal eating behavior is coordinated by the tightly regulated balance between intestinal, extraintestinal and central homeostatic and hedonic mechanisms, resulting in stable body weight. The ubiquitous availability and marketing of inexpensive, highly palatable and calorie-dense food has played a crucial role in shifting this balance towards hedonic eating through both central (disruptions in dopaminergic signaling) and intestinal (vagal afferent function, metabolic toxemia, systemic immune activation, changes to gut microbiome and metabolome) mechanisms. The balance between homeostatic and hedonic eating behaviors is not only influenced by the a…

Two weeks of early time-restricted feeding (eTRF) improves skeletal muscle insulin and anabolic sensitivity in healthy men.

Background: Altering the temporal distribution of energy intake (EI) and introducing periods of intermittent fasting (IF) exert important metabolic effects. Restricting EI to earlier in the day [early time-restricted feeding (eTRF)] is a novel type of IF. Objectives: We assessed the chronic effects of eTRF compared with an energy-matched control on whole-body and skeletal muscle insulin and anabolic sensitivity. Methods: Sixteen healthy males (aged 23 ± 1 y; BMI 24.0 ± 0.6 kg·m-2) were assigned to 2 groups that underwent either 2 wk of eTRF (n = 8) or control/caloric restriction (CON:CR; n = 8) diet. The eTRF diet was consumed ad libitum and the intervention was conducted before the CON:CR, in which the diet was provided to match the reduction in EI and body weight observed in eTRF. During eTRF, daily EI was restricted to between 08:00 and 16:00, which prolonged the overnight fast by ∼5 …

Hepatic arginase 2 (Arg2) is sufficient to convey the therapeutic metabolic effects of fasting.

Caloric restriction and intermittent fasting are emerging therapeutic strategies against obesity, insulin resistance and their complications. However, the effectors that drive this response are not completely defined. Here we identify arginase 2 (Arg2) as a fasting-induced hepatocyte factor that protects against hepatic and peripheral fat accumulation, hepatic inflammatory responses, and insulin and glucose intolerance in obese murine models. Arg2 is upregulated in fasting conditions and upon treatment with the hepatocyte glucose transporter inhibitor trehalose. Hepatocyte-specific Arg2 overexpression enhances basal thermogenesis, and protects from weight gain, insulin resistance, glucose intolerance, hepatic steatosis and hepatic inflammation in diabetic mouse models. Arg2 suppresses expression of the regulator of G-protein signalling (RGS) 16, and genetic RGS16 reconstitution reverses …

The Role of Intermittent Fasting in the Management of Nonalcoholic Fatty Liver Disease: A Narrative Review.

Intermittent fasting is a non-pharmacological dietary approach to management of obesity and metabolic syndrome, involving periodic intervals of complete or near-complete abstinence from food and energy-containing fluids. This dietary strategy has recently gained significant popularity in mainstream culture and has been shown to induce weight loss in humans, reduce gut and systemic inflammation, and improve gut microbial diversity and dysbiosis (largely in animal models). It has been hypothesized that intermittent fasting could be beneficial in the management of nonalcoholic fatty liver disease, given the condition's association with obesity. This review summarizes protocols, potential mechanisms of action, and evidence for intermittent fasting in nonalcoholic fatty liver disease. It also highlights practical considerations for implementing intermittent fasting in clinical practice. A sea…

Intermittent fasting in adrenal insufficiency patients: a review and guidelines for practice.

Ramadan fasting is a religious duty for adult Muslims. Even though sick people are exempted from fasting, numerous are those who insist on fasting, and seek advice from their physicians. The role of the physician is to support his patient and preserve his health. However, little is known about intermittent fasting in adrenal insufficiency. The aim of this review was to determine the risks of fasting in patients with adrenal insufficiency, the subjects at risk of complications, and the measures that can be undertaken for safe fasting. The analysis of the data of the different studies showed that there is a risk of complications during fasting in these patients. Optimal glucocorticoid replacement therapy for safe fasting has not yet been determined. Finally, a risk stratification and the modalities of the pre-Ramadan visit for adrenal insufficiency fasting patients have been suggested.

Effects of Intermittent Fasting on the Circulating Levels and Circadian Rhythms of Hormones.

Intermittent fasting has become an increasingly popular strategy in losing weight and associated reduction in obesity-related medical complications. Overwhelming studies support metabolic improvements from intermittent fasting in blood glucose levels, cardiac and brain function, and other health benefits, in addition to weight loss. However, concerns have also been raised on side effects including muscle loss, ketosis, and electrolyte imbalance. Of particular concern, the effect of intermittent fasting on hormonal circadian rhythms has received little attention. Given the known importance of circadian hormonal changes to normal physiology, potential detrimental effects by dysregulation of hormonal changes deserve careful discussions. In this review, we describe the changes in circadian rhythms of hormones caused by intermittent fasting. We covered major hormones commonly pathophysiologic…
