Intermittent fasting? Try the 5th century playbook

Lent is upon us – those 40 days of voluntary masochism that we moderns have mercifully put behind us. Or have we?

Fasting, at least in the health world, is no longer a derogatory term but one in vogue. Particularly the merits of the restricted diet, in which you limit the amount of time you eat either to a day (e.g. to an eight-hour window) or a week (e.g. skip eating on two different days). The latter approach, maybe surprisingly, follows in the footsteps of our religious forebears, who fasted every Wednesday and Friday. Could it be that they’d figured out a practice we are just discovering? And what else were they trying to achieve?

To a medieval peasant in Britain, Lent ratcheted up the twice-weekly fast. It was 40 days of a vegan diet, that often increased in intensity as the body adjusted (though the pregnant, young, sick and old were exempt). Lent also issued in much cultural creativity. Who knew that Cathedral at Rouen was a Lenten by-product, as those desperate for butter could get a dispensation by contributing financially to the Butter Towers (as they became known)? And Britons may have Lent to thank for both black peas, a Lancastrian delicacy, and fish & chips, as cooks were challenged to keep Lenten menus interesting.

Despite our caricatures of Lent as a dour and draconian time, it was essential to the enjoyment of medieval life. The purpose of Lent was not the denial but the renewal of pleasure. Maybe it’s precisely that aspect that has echoed through the centuries, manifesting now in our punishing diets, Tough Mudder races, and endurance stunts. Isn’t that a bit part of why we (well, some of us) do them?

'One of the principal rhythms of medieval life was this move from feasting to fasting to feasting again.'

Our modern fascination with fasting can also receive wisdom from Lent, which is that fasting for its own sake will always lead to something unhealthy. It must be for the purpose of something greater. Our forebears worried that physical practices could become idolatry, when wrenched out of their context of repentance. As G. K. Chesterton remarked,

'Physical nature must not be made the direct object of obedience; it must be enjoyed, not worshipped.'

The Old Testament prophets were particularly grumpy about this, insisting that fasting would do no good if it did not also help you love your neighbour more. Or as the early third-century Christians who fled from Roman excess into the deserts remarked,

'If you fast regularly, do not be inflated with pride; if you think highly of yourself because of it, then you had better eat meat.'

Fasting on its own will not make us better people, though we might shed a few pounds. Fasting is to restore the pleasure not only to eating, but also to the soul in need of God. Interesting that one of the primary biblical metaphors for a lively spiritual life is that of feasting and eating. Fasting resets the soul with repentance. It is praying with our body. It is not a negation but a purgation of desire – not denying our desires but resetting them. C.S. Lewis wondered whether our desires are not too strong, but too weak.

'We are half-hearted creatures, fooling about with drink and sex and ambition when infinite joy is offered to us, like an ignorant child who wants to go on making mud pies in a slum because he cannot imagine what is meant by the offer of a holiday at the sea. We are far too easily pleased.'

So if you’ve considered intermittent fasting, or even if not but you feel you might need a more balanced perspective on pleasure, consider the Lenten playbook. Feast and fast cyclically. Do it for a greater purpose than just losing weight. Let it change and reset your true desires. And maybe, just maybe, you might discover God waiting for you at the root of all your desires.

No mercy on the Megabus

Why is sin such a sickly, sticky thing in the human heart?

An upset man holds his hands on his head as he misses a bus.

“I’m begging you, I’m begging you,” pleaded the passenger. His two large suitcases lying around him, the Nigerian man knelt on the pavement outside the Megabus station. The bus driver stood surly-faced, arms crossed. The passenger’s jacket was ripped where the driver had shoved him off the bus. The passenger had one too many bags; he had not read the Terms and Conditions on his ticket.

The man groaned – “I must get to Heathrow, I have a flight to catch! I’m willing to do anything – to pay for an extra ticket, to pay the extra bag fee, I have money, see?” He showed the driver his wallet pleadingly, demonstrating his possession of several bank cards.

A few concerned passengers stepped off the bus. “We don’t have a bag in the hold; we’re happy for this man to have our space.” Another person said, “I booked a ticket but my friend didn’t come – there’s a whole seat’s worth of luggage space available in the hold.” Yet the bus driver would not budge. Even though Megabus has an excess baggage policy, it was down to the driver’s discretion. The driver alone had the power of life and death, to say “yay” or “nay” – to restore a man’s dignity or completely ruin it, along with his jacket.

As the minutes ticked on, other passengers began to get irate with the Nigerian man – “just buzz off mate, you’re making us late!” “You should have read the rules!” “You’re making the bairns on the bus cry!” Stony faces pressed against the window as the man knelt on the pavement. Even those who had tried to help him left him in the harsh hands of the bus driver and his colleagues, tiny kings in a kangaroo court. For the bus driver, there was no backing down – he was pacing, sweating and red-faced, repeating over and over again to himself his side of the story. And in the end, we left the Nigerian passenger in the heartless hands of bus bureaucracy, wiping our hands of the injury done to him – “we tried.”

How mucky and murky the human heart can be.

The whole experience on the Megabus that day left me feeling sick. We all like to think of ourselves as decent folks, as long as we do our “bit”. But on that bus I realized the difficulty: what is “my bit”? Who decides what is “enough”? How quickly a petty issue of baggage can descend into a power play. How quickly do ordinary nice people become a mob when they are outraged or inconvenienced. How mucky and murky the human heart can be.

The only word that feels strong enough to me to describe this condition is “sin”. This word may sound like a relic of a bygone Britain, but I think it’s as relevant as ever. It’s a serious word, loaded with a sense that the things we do mean more than we know. Sin suggests that I am accountable for how I treat people – not just to my own perception but some higher standard that safeguards the dignity of all human beings. Christians believe that it is God who safeguards our humanity, who sets the standard for how we should and should not treat others. We are accountable “vertically” – to God – as well as “horizontally” to each other.

It seems to me that “sin” is not a laundry-list of rules but more like a tangled knot of slippery threads – I can’t see where it begins and where it ends, in my own heart or in the world at large. The Christian Eastern Orthodox tradition often likens sin to sickness or a dis-ease of the soul; it infects our reasoning, our emotions and our actions. And that’s why the hurt and pain we cause each other is so “sticky” – no one is left untouched by the effects of the damage we cause each other.

It was quite clear to me that there were some “sins of deliberate fault” on the Megabus that day – the bus driver’s behaviour was patently unfair and verging on abuse. But I would say sin also flourished in the self-defending logic of the passengers who just wanted to stay in their lane, and for the Nigerian chap to stay in his. Don’t bother me, with your problems. I look after me, you look after you. There were sins of ignorance too – I felt this sick sense in my stomach as the bus pulled out of the station that there was more I could have done, but I didn’t quite know what. All I know is that every person needed mercy on that Megabus, whether we knew it or not. Ironically, the Nigerian man was the most innocent of all.
