A 7-day Intermittent Fasting experiment


I’ve been interested in Fasting ever since I saw the Michael Moseley Horizon programme in 2012, not just for weight loss reasons, but rather the claimed health benefits – lowering the risk of developing diabetes, dementia and cancer.

Fasting purportedly diverts energy and resources away from food digestion, focussing instead on doing useful housekeeping things like cell repair, reducing insulin levels and generally ridding the body of toxins and other debris. It also re-teaches the body the lost art of deriving energy from fat, as opposed to from the carbs in our belly – a process called Ketosis. Most of us carry enough fat to survive several weeks without food, which is why fasting is safe, and why many people have successfully conducted 21 or 28 day fasts without any harm.  It’s also popular in many religions and spiritual practices – Islam (Ramadan), Buddhism, Bahá’í, Christianity, Hinduism, Judaism, Jainism, Sikhism, Taoism … the list goes on.

Even outside of religion and spirituality, fasting has been a natural part of human existence for as long as we have been around, primarily because food was scarce and so early man had to eat when he/she could, forced to fast in between hunts and catches. We are therefore designed to cope well with fasting, it’s in our genetic make-up, even if it does feel a little alien to the modern psyche which has been raised on the 3 square meals a day regime (3SMAD). The introduction of 3SMAD has its roots traced back to 19th Century America – it was a symbol of civilisation to sit down with friends and family at fixed times to eat, an attempt to differentiate the ‘civilised’ white man from the indigenous natives. It could therefore be argued that fasting is more natural to us than 3SMAD.

Nevertheless, many people will still argue that 3SMAD is best for us and that fasting is sheer madness. People will claim they feel ‘shaky’ if they miss lunch, and cite this as evidence they need to eat, but there is a counter-argument that your body has just become so dependent on deriving instant energy from food carbs that it’s forgotten the lost art of ketosis which fasting allows.

I therefore decided to give it a go for a week. Instead of the traditional 5:2 diet which I followed for a year or so but found rather difficult, I decided to try just eating one meal a day, every day, limiting my calorie intake to a couple of hours each evening. That means eating nothing whatsoever for 22 hours – no sugar or milk in tea, certainly no snacks or fruit, just water, tea and an occasional black coffee. You could call this the 7:0 diet – a little extreme maybe, but if the theory of ketosis is sound, I figured it wouldn’t be anything more than a psychological challenge. If you want more detail on this, I got the idea from the following video Eating Once a Day.

Important to note I placed no restrictions on what I ate (or drank) in these two hours. I didn’t cap calories or consciously cut out any food groups.  I even allowed alcohol because I know if I had banned it, I would have fallen at the first hurdle. What is interesting, is what happened:

My Diary

Day 1 – not surprisingly this was easy, after all I had a corpulent body full of yesterday’s 3SMAD excess calories to keep me going. I didn’t want any alcohol and just ate a moderate plate of veggie grub.

Day 2- felt good, loved waking up and not having to worry about food all day, a feeling that persisted throughout the week. Interestingly I only had (only wanted, only needed) a light meal, although it was accompanied by a glass of wine. Day 2 was a Friday, and had I banned alcohol in this experiment, I may have felt resentful and rebellious. However, without any alcohol ban I was free to enjoy a glass, and because I felt good about the fasting, I wasn’t tempted to drink any more, ending the evening feeling unusually virtuous and sated.

Day 3 – felt good, went for a long walk during the day (4 miles), had a veg stir-fry for dinner plus two glasses of wine (it was Saturday night). I didn’t really enjoy the second glass of wine – one would have been enough but in a perverse mindfcuked reasoning kind of way that only I could muster, I convinced myself I should have a second glass to prove to myself I wasn’t restricting alcohol.

Day 4 – hard, very hard. Perhaps it was the wine? Who knows, but I had a persistent headache all day, felt tired and sluggish despite sleeping well and craved food throughout, occasionally staring balefully at the cheddar cheese in the fridge. I only just made it through to tea-time, but interestingly didn’t have (or want) any alcohol. Veg Thai green curry (no noodles).

Day 5 – much better. I was busy which helps a lot and I just had a light veg dinner. No alcohol. I definitely felt lighter and I’m definitely sleeping better and eating much healthier food through choice/desire. No cravings whatsoever for junk food (odd for me) and most surprisingly of all, despite not restricting alcohol, I’ve only had 3 glasses of wine in the first 5 days, including a weekend, and anyone that knows me will know that’s quite uncharacteristic.

Day 6 – all went well, seems to get easier. Had a light veg based dinner, no alcohol. Sleep continues to improve. Once again my focus and concentration was immense, far better than usual and my work productivity has undoubtedly increased. Managed a 2.5 mile run.

Day 7 – felt harder. Perhaps knowing this was the last day made me psychologically weak, like I sensed the finish line. But that makes it sounds like it’s been a hard slog and it really hasn’t. I’m only stopping today because I set myself a 7-day target for this experiment and the more I look at it, the more I believe I could continue further. I survived and rounded off the 7-day fast with an oven baked jacket potato and cheese like mama used to make. Enjoyed a 3-mile walk.

In summary

I would say on average I have consumed well under 1,000 calories a day, probably closer to 600-700, and interestingly have eaten smaller portions and higher quality evening meals than I ever did on 3SMAD. I also rarely craved junk food and 3 glasses of wine was well under par for me for a weekly total. I also ate total vegetarian – due in part to a bountiful supply of garden produce, but certainly not a conscious action at the outset of the experiment, perhaps this was pure coincidence.

Of course 600-700 calories a day isn’t sustainable long term, but I guess that’s where ketosis comes in, at least in the short term. I have AMPLE fat stores to draw upon, as do most of us fortunate enough to live in the western world, and so such a challenge over a relatively short period of time is only ever a psychological one I think. This was never going to be, nor ever planned to be, sustainable, I just wanted to check if it was doable, and it was. It’s foolish to draw any firm conclusions, but it has proved to me you don’t have to eat at set meal-times, it’s OK to skip a meal (or two), and in fact it might even be good for you to listen to your body rather than the chimes of the clock.

I have no idea what it has done for (or to) my health, all I can say is I felt better afterwards than I did at the beginning. I felt like I had more energy and my brain was definitely sharper – I could concentrate for longer and didn’t feel sleepy during the day. For the record I lost 3.4kg (7.5lbs) in weight. No doubt much of that will go back on when I return to normal eating, although, and here’s the crux, I’m not entirely sure I will return to my normal 3SMAD eating, but perhaps somewhere in between.

I’m certain many of you will think this was a silly and dangerous thing to have done. All I can say is I survived and as described above I felt better than I did previously. Best of all I believe I now have a much better perspective and handle on my, admittedly rather quirky relationship with food (and maybe also drink).




The driest of Januarys …

Edit: I only just realised by re-reading some of my old blogs that I did dry January 3 years ago! I have no recollection of that, so apologies, this wasn’t in fact the driest of Januarys, but certainly one of them.

As I’ve blogged previously, the new year is always an important time for me, a time to start afresh and right the wrongs from the year just gone. And in recent years I have been following other people’s Dry January with interest – a challenge where folk try go the first month of the year without any alcohol.

Unfortunately for me, my birthday is on 2nd January which makes Dry January extremely challenging. Of course my wife who has a healthy outlook on such things, just suggests I start Dry January on the 3rd day of the month and continue through to 2nd February. As always she is being hyper logical, but to my OCD mind that’s a horrific nonsense and a complete non-starter. That would make Dry January not at all Dry January but Dry-for-most-of-January-and-a-little-bit-of-February which is just plain silliness.

For some reason this year I really wanted to do Dry January and through December it was all I could think about. I was bored and tired of boozing, having reached the point where I was drinking out of habit. I was drinking good stuff too, quality wines, not cheap plonk, yet I was still feeling indifferent, somewhat ‘meh’ about the whole thing, like what was the point?

And so, at midnight on New Years Eve, I toasted in 2016 and put down my Prosecco glass. It was actually 12:07am which made me feel slightly sick, but I managed to convince myself that’s OK, it was a drink that I began in 2015 and it was New Year’s Eve, so I cut myself some slack and started the clock, managing to navigate a dry birthday on day 2.

By way of background, let me add that my previous alcohol-free, all-time-since-I-have-been-an-adult record was 17 days achieved in January 2011. I know that because I record these things and have done since I was 22 when I started to jot ‘AFD’ on the corner of my pocket diary on each day I had no booze (alcohol free day). What happened in January 2011, after 17 consecutive AFDs, was that my wife and I were invited next door for dinner and I couldn’t say no to some wine. My journal entry for the following day was littered with self loathing to levels even extreme for me.

January 2016 felt different, and it was. I remained dedicated to the cause, I remained full of resolve and breezed through to Feb 1st with only the slightest wobble on a business trip to Athens on 25th Jan when I was offered a glass of Ouzo to toast a new business relationship. I surprised myself by politely declining it and toasted instead with my glass of Athenian sparkling water.

Apart from the challenge in and of itself, I found the 31 day journey quite enlightening. My sleep was definitely of a higher quality, and I noticed early on how my mental state of mind had improved. I felt less paranoid if that makes sense? Maybe it only makes sense to paranoid folk, but I definitely felt it, and I felt much calmer, more relaxed, less on edge. I was also eating better, resisting the urge to snack on crisps and other snacks which always went hand in hand with a pint or a crisp glass of wine.

I also lost weight, around 11lbs (~5Kg). I wanted to lose weight, I needed to lose weight and so that was a great bonus and incentive for me. I know the caloric reduction from no booze wasn’t the only factor, but not drinking made me eat better, exercise more and sleep better, all factors which contributed to the weight loss.

So what now? I panicked on February 1st, imagining my first drink undoing all the good from January. I actually dreamt waking up on Feb 2nd at 4am in a prison cell with no pants on, I was clearly 5kg fatter with popcorn stuck to my gob and curry sauce on my chin. As you may recall, dear bloggers, I don’t do moderation very well and so I knew it wouldn’t just be one drink, it would be a bottle and possibly more.

Drinking would of course also mean breaking my AFD run, I would be back at square 1, I would have ruined everything so what would be the point in doing anything after that other than drinking more? Awful scenario. My mind works in mysterious ways.

So here I am, Tuesday 2nd February 2016, still 2016 clean and very much enjoying it. I have decided however not to set any more targets, no more goals (for now), instead I will just take it one day at a time.

If I want a drink, I shall have one. The thought of never drinking again makes me feel sad, perversely the thought of having a drink also makes me feel sad, and so I am taking it one day at a time, each day on it’s own merit, and perhaps one day in the near future I will decide the time is right to have that drink.

And I sincerely hope that when I do, I don’t wake up naked in a prison cell.

A very dry January

So, I did it.  I managed to go an entire month without any alcohol, an oft attempted NY resolution with a 0% success rate until now.  In fact I have never reached 3rd January before without falling off the wagon which is spectacularly bad, although in my defence 2nd January is my birthday.

Not wishing to go over old ground from my previous blog, let’s skip straight to the key points.  What have I learned?

I now know I can go a whole month without alcohol.  Whit-whew, whoop-di-doo, get me.  The objective in itself is meaningless without looking at the tangible benefits so here goes:

1) Financial
I estimate I drink 4 bottles of wine a week normally @ ~£6 a bottle, with one visit to a pub for a couple of pints @ £3.50 a pint.  Add to that a couple of G&T ‘sharpeners’ to kickstart the weekend and perhaps a cheeky late night Malt and that’s another £3-ish, so approx £35 a week.  £150 a month.
Impact: Significant

2) Weight
I lost around 4Kg from 1-31 Jan, approx. 9lbs, but there are a whole load of caveats here.  Firstly, it was January and I always begin the year at my heaviest after a libidinously indulgent festive season, and so by doing nothing different I would expect to shed around 3lbs anyway.  I also watched what I ate and did some 5:2 fasting and whilst I don’t enjoy the success my wife does, I suspect this also contributed to a couple of lbs of weight-loss too.  I’ve also been exercising a lot, although when I was training for the London Marathon in 2008, averaging 30-40 miles running a week, I still didn’t lose any weight, so not sure I can attribute much weight loss to exercise.  I would therefore suggest around 2lb in weight loss attributable to not drinking.  That’s still 24lbs extrapolated over a year.
Impact: Significant

3) General health
I definitely exercised more due to feeling good each day and not hiding behind the hangover.  I also saw a marked improvement in long term running injuries for the first time in years, which I would say is an indirect consequence of not drinking (not drinking -> more exercise -> improved strength & conditioning).  I have felt pretty fit and perky throughout, certainly more than usual and this might be psychological. Sometimes after a boozy session I just assumed I would be tired and therefore probably was.  Conversely now I expect to feel better and therefore do.
Impact: Moderate

4) Sleep
A big problem of mine traditionally.  Interestingly I have had a lot going on with work this month (a usual cause for poor sleep) and yet despite this I have definitely slept better than average.  Still had a couple of bad nights, so not a cure but a marked improvement in the quality of sleep if not the duration.
Impact: Moderate

So some tangible benefits there, the main one being financial followed by some weight/health benefits.  I haven’t done detailed blood tests which could add extra weight to these arguments.  For example a reduction in cholesterol or BP or glucose levels would certainly push this category more towards ‘Significant’.

Much easier than I ever imagined.  During the last two weeks I even forgot to count and I had days where I don’t think I ever thought of having a drink.  I only went to a pub once and found that really hard.  I did stare a little too longingly at some blokes drinking pints of what looked like gorgeous tasting ale, but what I missed more than the taste was the ‘occasion’.  Going to a pub with friends/family and not drinking feels odd in a “why bother?” kind of way.  The best way to describe this is to say that I felt a bit sad.  I missed that chilled feeling, that warmth and relaxation, that light, heady fuzz that comes from the first pint, that feeling of walking back to the bar for a second one because you’re in the zone.  I really missed that as I drank my orange juice and tonic.  I also missed a glass of red with certain meals.  Wine just goes together with food like no other drink can. That wasn’t so much the need for alcohol, but the need for a full flavoured drink that isn’t gassy, suger laden or just plain bland.

I’m pleased with the results and pleased with my ability to remain resolute throughout.  Now I face a dilemma of what to do next.  My inability to moderate worries me – the ‘cheesy wotsit’ syndrome (see last blog) worries me.  I certainly don’t miss hangovers but I do miss the social side of drinking and the sensible answer is to resume drinking but in moderation.  Easier said than done in my case.

We’ll see.

Liar, you self righteous, pompous bore

It was around the time I turned 40 that the hangover became a two day affair.  As a younger man, a mug of tea and a bacon butty would usually clear the fug, but in my 40s, I noticed it took much more, and with a much longer recovery period.

As I get older, I have noticed I’ve developed a much more focused sense of my own mortality.  Niggling aches and pains, recurring and persistent injuries that won’t go away, and other medical ailments that were once just words you heard uttered by grandparents, are now being uttered to me, by my own doctor.

I’m certainly not alone here I think, friends of mine are also suffering more.  High blood pressure, high cholesterol, overweight, warnings of heart problems, cancer scares, warnings of impending diabetes – these are all phrases I hear increasingly.  Some directed at myself, some at friends of mine.

Sometimes, at least in my view, the medical responses are lazily diagnosed by disinterested GPs (I will blog about Statins one day), but generally the basic premise, the warning, is usually well founded in solid science.  In layman’s terms they’re clear indications that our bodies are being stretched beyond their functional operating range, and we all face two choices in response to such news – we either carry on, ignoring the warning signs, continue to live life to the full and perhaps die at an earlier age (crash & burn), or we moderate our behaviour in some way.

I’m not preaching one approach over the other here.  Each to one’s own, say I.  Some people are perfectly happy living their lives to the full, preferring to burn the candle at both ends, possibly dying earlier but leading a much higher quality existence in the meantime.  I’m too scared to do that.  Death worries me, I have too much still to do and I’m not ready to ignore these warnings, so my personal choice is to try and follow the second route of moderation.

As a younger person, moderation to me just meant having a day off, whereas in my 40s it really means lifestyle changes, serious lifestyle changes, and that takes a lot of getting used to.  Especially for me as I haven’t traditionally done moderation very well as I tend to do extremes.  Intense days of excess, followed by several days of complete abstinence.  And as I said earlier, that seemed to work as a kid.  Flush out the old system, give your body a ‘ctrl-alt-del’ style reboot and off we would go again.

That doesn’t work too well in middle age though.  I’ve found that out, and that’s why I’m now trying to practice the true art of long term moderation.  That no longer means taking it easy Mon-Thurs then going balls-out Fri-Sun, it means taking it easy, (almost) always.

At first that was a depressing thought, but recently I tried it.  This past weekend was an interesting one as I had social events Friday night, Saturday night and Sunday afternoon.  All three events centred around drinking, as is the British way, and so all three came with a certain level of social/peer pressure to participate.

In the past, when trying to moderate and faced with such a weekend, I would have responded in one of two ways:

  1. avoided the occasions altogether, made excuses and not turned up, or
  2. dragged myself reluctantly to the events and sat in the corner avoiding as much human interaction as I could get away with, watching the clock, rocking from side to side, sobbing and stroking a dead sparrow, begging my wife to take me home so I could beat myself with birch twigs.

This weekend however, I tried a different approach.  On Friday night I had one pint of Guinness, and no more.  On Saturday night I had one glass of champagne to toast soon-to-be absent friends, and on Sunday I just drank soft drinks.  Sounds easy doesn’t it?  But for me that isn’t easy.  For me, that first drink has always been like a klaxon going off in my head, the sign that we are now officially off and running, the red mist would rise and that first beer would turn into a second, that would turn into a third, then perhaps move onto wine if I was feeling bloated from the ale, maybe 2-3 glasses of Shiraz (ironically feeling virtuous having switched from hop to grape), then be driven home to continue drinking in front of the TV, rounding off the evening off with a couple of fine malts, convincing myself I deserved them using some kind of warped logic that also makes the drunkard think a kebab is a good idea at 1am.

And you know what?  It felt good*.  And that’s because a significant knock-on effect of not boozing is an improved diet.  The urges for that kebab or another bag of crisps are nowhere near as strong or as attractive to the sober mind as the inebriated one.  The perverted logic that I need salty, fatty food to soak up the booze looks as flawed as it always should to the sober mind, whereas to the soused brain such logic seems scientifically sound and positively health promoting.  “Yes, a burger from that white van opposite the taxi rank, that’s just what I need right now, I am going to live forever”.

I enjoyed my weekend.  I did have a couple of drinks, drinks I enjoyed as drinks in their own right, not as precursors to an evening of hedonistic indulgence.  I had many lucid conversations with friends, made some new acquaintances, and still remember their names.  I slept well, rose early each morning, had productive days and returned to work on Monday feeling relaxed, fresh and raring to go.

* What utter bullshit.  I looked on more than a little enviously at some of the imbibers who were slurping their way through several bottles of very nice red wine, pizza cheese stuck to their chins, and I desperately wanted to unshackle myself from this new, boring regime and get bloody stuck in.  I wanted it badly and I felt utterly miserable nursing my warm, flat, sweet glass of coke.  I looked on misty eyed.  I called them names.  I was insanely jealous if truth be told.  I wanted to do that so much.  I told myself it was the chimp inside talking, trying to get out, the chimp who desperately wanted me to be one of the troop, down with the lads, getting wrecked.

But I can’t.  Not any more.  And it’s hard.

Hindsight is a mischievous thing

What do I have in common with Sir Ian Botham and Freddie Mercury I hear you ask?  To answer that we need to return to August 1986, but before that let’s travel briefly to the mid-70s.

I was a very skinny kid.  Growing up I was always conscious of my bandy legs, pencil thin and knobbly kneed they were.  Strong, muscled, masculine they weren’t.  I have a lingering memory of my mum coercing me to put shorts on during one particularly long, hot summer.  It could have been the heatwave of ’76, I can’t recall exactly, but I do remember that I was so self conscious of my twiggy extensions that I refused to take off my (probably flared) corduroy trousers when I went out to play.

And yet here I am, in middle age, now overweight, and now as conscious of my heftiness, as I was of my skinniness as a child.  I’m not the kind of person who gains and loses weight, I don’t yo-yo like some people do. To borrow a mathematical term, my weight has been monotonically increasing since the day I was born, give or take the odd diet or Delhi belly episode, here and there.

This led me to thinking therefore, that there must have been a point when I was the ideal weight, sometime between ‘then’ and ‘now’.  There must have been a moment where my physical stature was just about right.  I don’t want to con my readership by suggesting I was ever Adonis-like in any way, and I am sure even back then I was still unhappy about certain features, but of course what I never realised or appreciated, was that that was it, that was the best it was ever going to be for me.  Only hindsight offers me such a perspective.

I remember after I left university and started working in London, that I slowly started to become conscious of my weight.  The heavy boozing through my university years and the inevitable slowdown in physical activity that accompanied it, were starting to take their toll.  That was September 1986, ergo, I reckon August 1986 must have been when I was at my absolute physical peak.

I remember now, I went on holiday to the USA in August 1986.  We were 2 boys and 2 girls fresh out of university.  We travelled through Connecticut, New England, New Hampshire, Vermont, Montreal, Toronto, Chicago.  We visited Niagara, we took in a baseball game at the White Sox, we stayed in cheap motels, we stopped wherever and whenever we wanted and we partied long into the night.  I think one hot day on that trip I even took my t-shirt off, further evidence if needed that I was indeed at one with my physical self.  Happy days.

Also during that month in August 1986, when I was enjoying my peak, one of my boyhood heroes, Ian Botham (a man who ironically also battled with his weight later in his career), returned to test cricket after a ban for taking Cannabis.  He was recalled at The Oval against New Zealand, and with his second and 12th balls took the two wickets he needed to equal, and pass, Dennis Lillee’s then world record of 355 Test wickets.  Botham went on to play international cricket until 1992 but only collected another 30 or so wickets in those intervening 6 years.

August 1986 was also the month that saw Queen play their last live gig with Freddie Mercury as frontman.  Mercury’s final live performance with Queen took place on 9 August 1986 at Knebworth Park and which was rumoured to draw an attendance estimated to be as high as 300,000. 

So the answer to the opening conundrum is that Andy Ramsden, Ian Botham and Freddie Mercury all enjoyed their peak in August 1986. Although none of us knew it.  It’s only with the luxury of hindsight that we can look back and identify the peaks and the troughs.  At any point in real time, whether we feel low, or high, we never know if we have troughed or peaked until some time after the event.  Ah, the benefit of hindsight.  

‘Beefy’ probably thought he could take another 100 test wickets.  Freddie probably already had the lyrics laid down for his next album, and as I drove along the freeways of North America, fresh out of university, reading Jack Kerouac, listening to Joni Mitchell, contentedly stroking my six-pack with one hand whilst drinking a Michelob with the other, I certainly never believed for one moment that I had a 20 year career at BT waiting for me at Heathrow in just 2 weeks time, along with a monotonically increasing waistline that would continue to grow with me from that day onwards.

Sadly Freddie is no longer with us, but Ian and I continue to waddle on.  With life experience behind us instead of in front of us, we re-adjust and reset our goals to more realistic levels.  

Ian and I both still enjoy a glass or two of red wine (allegedly), and I don’t doubt that just as I occasionally sit back and think about that crazy, hot summer in North America, that Ian perhaps does the same, recalling the LBW of Jeff Crowe that gave him his world record 356th test wicket.  

If only we had known then what we know now, would we have followed different paths?

Carpe Diem.
