So I decided to try intermittent fasting. Not for religious reasons, but to see if all the beneficial things I had read about limiting your food intake to a restricted number of hours per day were true. Depending on who you ask, this alternative eating pattern will decrease your blood pressure and cholesterol, increase the efficiency of your metabolism, and even invigorate you on a cellular level. Now I have no way of knowing if all this is true, but I do know Hugh Jackman claimed intermittent fasting was an integral part in his transformation to play Wolverine, and the evidence there is pretty good…!
Me after a month of intermittent fasting. Not.
I’ve done it for a month now. Eating between noon and eight in the evening, and nothing but water the rest of the time. So how did it feel? I was afraid it was going to be incapacitating and overall horrible, but it wasn’t. Turns out you can function quite well on an empty stomach. You can even go running for two hours on a hot day with high humidity and feel none the worse for wear (well, in terms of hunger and stamina – don’t ask me about my Achilles’ tendon!). If anything I felt a lot better for skipping breakfast. You feel sharper, less prone to carb-induced lows (since you haven’t had any!). There was suddenly a lot of free time in the morning, but that never seemed to be a problem, and quite apart from that, the fact that I was genuinely hungry by the time noon came around meant that I really appreciated what I ate – hunger really is the best condiment.
What about all the health benefits? I don’t know. I didn’t lose any weight (and that wasn’t the purpose of the experiment anyway) but I feel slimmer. Researchers have shown that what will happen when you fast is that you’re depleting the liver of glucose, which means your organism will have to start burning fat instead. This is known as ketosis, and since this happens within 16-24 hours of your last meal pretty much regardless of what or how much you eat, maybe I achieved ketosis in spite of eating lots of carbs. That’s my story anyway, and I’m sticking to it.
More to the point tho, will I be sticking with this new eating regime? In as far as it is practical, I think I will. Like other changes to my diet – notably giving up coffee and alcohol – people around me seem to think it a little weird, but just because we have been brought up to take three meals a day as a given doesn’t mean it should be. Our ancestors certainly couldn’t count on that kind of regular food intake, and – as is the case with the paleo diet – I think there are strong arguments for trying to emulate the way nature intended for us to live. That’s not to say I won’t have the occasional all-out breakfasts occasionally – after all, what’s the point of evolution if you cannot have American pancakes with butter and maple syrup every now and then?
It’s fair to say the year ended on a bum note. Things don’t always go as planned. But what of the rest of the year? Time to look back and reflect on what went according to plan, and what didn’t.
But for the butt injury, I might have had a sporting chance at reaching my distance goals for running and biking (averaging a marathon distance per week for each), but realistically that was too much. I did do that much on average when at home, but traveling got in the way, and that lowered total mileage significantly. Need to set more realistic goals, especially with next year’s runstreak requiring time every day.
I did my first ever triathlon – an Ironman 70.3, and the result was better than I had hoped. Still not sure whether a full-length one is worth the trouble, but maybe… saying I did half-something jars my soul!
I didn’t lift weights, swim or do yoga anywhere near as much as I had planned. I did some, but found it difficult to fit it all into my routine. Will have to find another balance to make it all work. And actually learn how to swim.
So much for fitness. I didn’t read as much non-fiction as I would have liked, but what I read was good. I’ve played a lot of chess and piano, and studied French, too, but I’m still not sure how to measure progress here. I know I am progressing, but how to tell? The system of dividing up the day into half hours to ensure that things get done works, at least, so I will continue doing that. And only watching Netflix when I’m on the stationary bike will kill two birds with one stone…!
Travels and challenges, then? I certainly travelled a lot, and two themes emerged: island hopping around Africa, covering Pemba, Mallorca, and Madeira (following on from Malta), and hiking in the alps in France, Bavaria and Sweden (ok, so we don’t have alps, but parts of Bergslagsleden were really hilly!). Add to that the two(!) trips to Andalusia – once to see Alhambra, and once to learn how to paraglide – and a nice long weekend in Paris, and you have what I would deem a pretty good year of wanders. More of that, please.
Lest I forget, the year has brought some wonderful new people into my life, as eclectic a bunch of characters as one can hope for: an Argentinian telenovela starlet in Tanzania, a Scottish philosopher in Spain, my own personal stalker, a Phillipina philanthropist, a Swedish ultrarunner in Amsterdam… in fact, if I were to write a book about them all it would probably seem outlandish, which brings me to my last point: this blog.
I’ve continued to write throughout the year, about everything and anything, from great tits to particle accelerators, and my readership is steadily increasing (visitors up 25% (to 2800+) and views up 50% (to 5500+) at the time of writing), something for which I’m immensely grateful! It’s humbling to foist your words on people and have them not only actually read them but also come back for more. So thank you, dear reader. I hope you have enjoyed the ride this far.
The second half of my month of eating paleo looked like it might be considerably harder than the first. Eating nothing but what our most distant ancestors might have eaten works fine when not exerting oneself utterly, but as my triathlon draws closer that’s not an option. Plus I would be going hiking for five days with my brother, and goodness knows how my body would react to that, paleo or no. This is what happened:
Day 16: 10k bike / 2k swim brick-session (i.e. one follows immediately upon the other). No problem.
Day 17: 18k bike, 8k run, 6k run, all with hour-long pauses in between, and 28C temperatures. By the end of the day I’m exhausted, but somehow I don’t think the diet is to blame. I cheat a little afterwards, drinking half a litre of pure apple juice – it tastes like the nectar of gods!
Day 19: I discover that smoked trout and boiled eggs make a good breakfast, but leaves your mouth smelling like fart. Learn something new every day.
Day 20: New PB on 5k. Wonky reading on the Garmin tho, so won’t count it, but still: clearly paleo isn’t hurting more explosive efforts either.
Day 21: Prepared massive batch of protein cakes to bring on next week’s hike. Tweaked the recipe to include maple syrup and chocolate. All caveman kosher. Biggest problem will be not eating them before actually on the trail…!
Day 23: Hiking all day. 18k in hard terrain in Tiveden. Protein cakes yummy. Freeze-dried food better than expected. Energy levels stable and high.
Day 24: Hiked 20k. Ate big plate of macaroni and cheese in the evening and literally passed out for half an hour afterwards. Just laid down on the ground and fell asleep. Felt hung over on carbs the rest of the evening. Disgusted.
Day 25: Hiked 23k. In the evening an old friend met up with us, and served us cold beers and Brie sandwiches. Couldn’t say no out of politeness. Didn’t want to, either. Paleo regime officially toppled, then. Will mount a counterattack. Tomorrow.
Day 26: Got up at 0400. Hiked 32k over ten hours. Gratefully accepted a beer in the evening from kind strangers, but otherwise toed the line.
Day 27: Last day of hiking. Family reunion. Lots and lots of food. Decided to forgo paleo for the evening.
Day 28: Back in Belgium. Rest day.
Day 29: Rest day.
Day 30: Went running for the first time in over a week; shaved another sec off my PB on 5k. Celebrated daughter’s birthday with huge, distinctly non-paleo cake.
Day 31: 10k bike (PB), 8k run, 7k run. Weighed in: 77.2kg.
So, strictly speaking I stuck with the diet 100% for three weeks. After that circumstances conspired to make things more difficult, as I had predicted. That’s never an excuse tho; I chose to give it up for the sake of convenience.
But that doesn’t change the fact that I was able to work out as hard as I ever have in my life during those three weeks, and it felt great. I lost five kilos during May, without losing any muscle, so it seems the theory holds water – your body will switch to burning body fat if carb intake is significantly reduced, and do so without lowering your performance levels, over either short or long distances.
It will be interesting to see what happens at the Ironman triathlon in three weeks – that will be the real litmus test. I will be writing about that experience too, of course. One thing’s for sure: I’ll be continuing on this prehistoric path.
So for the month of May I challenged myself to go on a paleo diet, in order to see how this might affect my well-being and physical performance. Here are some of the highlights of what happened:
Day -1: Panic. I’m supposed to not have any sugar for a month!?
The healthy thing to do would have been to research recipes and prepare. What do I do? I run out to the local night shop and get an overpriced bucket of Haagen-Daez ice cream and down it all in one sitting, then – predictably – feel horrible about it. At least I didn’t have a beer as well.
Day 1: Breakfast is made up of bullet-proof coffee (black coffee with a dollop of coconut oil in it) and left-over oven-baked chicken with mozzarella; how’s that for high fat, low carb? It feels a little weird, eating chicken first thing in the morning, but hey, embrace change, right? Only I have the same thing for lunch AND dinner, and now I do feel a real need for change.
In terms of training I don’t do anything more strenuous than a short run, which a post-workout banana covers just fine. It remains to be seen how longer bouts of exercise affect me…
Day 2: Reading up more on paleo, I discover all legumes are banned. No beans. I literally had cans and cans lined up on the kitchen counter to make a big batch of chili con carne! No sweat, old bean.
Also, no dairy is allowed, so my buffala mozzarella yesterday wasn’t caveman kosher either, in spite of the fact that trying to milk a buffalo is a pretty Neanderthal thing to do. Crud. Two days in and I’m failing. There’s a learning curve to this, clearly.
I buy a spiralizer to make zucchini “pasta” for dinner and find it surprisingly edible. The kids threaten to go on hunger strike, then devour almost an entire cheesecake with raspberry coulis for dessert while I watch.
Day 3: Weight-lifting after an English breakfast goes well. A banana, a date and some walnuts plus lemon water with a shot of flax seed oil replaces my usual (milk-based) protein shake. So far so good.
In the afternoon the kids have an hour each of breakdance (L) and hiphop (R) with an hour in between, so the plan is to run while they dance. First hour is no problem, the second one I struggle, but more because I’m tired from this morning than anything else. And three workouts in a day is a fair amount, caveman or no.
Day 4: Brought carrots, strawberries, dates and walnuts to work to tidy me over until lunch. Worked well.
Dinner I’m invited to an Italian friend whom I’ve completely forgotten to inform about my new habits. Shit! In my mind’s eye I see a mountain of Parmesan-powdered pasta looming, followed by troughs of tiramisu, but my gracious host is very understanding, and beyond the guilty pleasure of a smallish plate of spaghetti vongole I don’t stray from the path.
Day 7: I want to test myself (and the diet), to see if no carbs for a week will mean bonking when keeping up a sustained effort. So I do an hour of swimming (2k) followed by a three hour walk (13k), stop for lunch, then go biking one hour and a bit (25k). Admittedly this isn’t anywhere near as much as a marathon or triathlon, but I do it all without getting particularly tired or feeling any need for carbs. Yay!
Day 9: 16k run. No problem.
Day 10: Becoming accustomed to eating “nuts and roots”, as my sister put it. Breakfast is dates and cashew nuts, carrots and hummus, plus a couple of eggs. Apart from the coffee, it feels like something the first guy to climb down from the trees might have eaten. He probably didn’t read his New York Times daily briefing while doing so, but so what?
Day 12 I run equal parts nuts (pecan, walnuts and cashew) and medjoul dates in a blender to create the simplest and best “cake” ever (1 cup of each; calories: approximately 1 gazillion). Who said troglodytes didn’t know how to party?
Ate it all in one sitting, and a good thing too, because Day 13 I swim 3,000m for the first time since I was 18. And then do an hour of weights.
Day 14: Brunch with a friend. Half of what they serve is bread, or sugar, or both. I try a teaspoon of tiramisu (which I normally adore) and it’s so sweet I can hardly bring myself to swollow. Luckily the other half is made up of yummy veggie dishes, so emerge quite sated.
In the afternoon I run a half marathon on nothing but water. 1:52:50. Good time, given previous day’s workouts. Still don’t feel the need to refuel during the run. Scales show I’ve lost three kilos in two weeks. Not a bad first half!

(A friend objected that people get paleo wrong, in that they eat meat a lot more often than our palaeolithic forefathers and -mothers did; this is an objection I would say is probably correct. Even so, I’m buying a lot more veg than usual, and I feel good: slimmer, lighter, never quite as ravenous nor as zonked out before or after meals as I normally get.)
Urgh. Gruff. What is this M&M’s of which you speak?
Remember the bit in Pulp Fiction where Marcellus Wallace promised to get medieval on someone’s ass? Always sounded like a good threat to me. (I imagine it would involve building cathedrals and trading in relics…)
However, the whole world seems to be hellbent on going much further back in time, with Trump wanting to bomb everyone into primordial soup (presumably to level with his intellectual discours). So in keeping with that spirit, I figured the month of May might be a good time to challenge myself in a new way: by getting Stone Age on my own ass.
It’s not as mad as it seems. I’m not proposing to go live naked in a cave and hunt mastodons for breakfast (although that would be fun, too), no, what I will do is go on a Paleo diet for a month, to see what happens. Paleo is essentially about eating the way our earliest ancestors did, in an attempt to get away from starch, sugar and carbs – something which those early hunter-gatherers didn’t find much of on their menu.*
It will require quite the change to my eating habits: no more oatmeal and milk for breakfast, no pasta, beer or pizza post long runs, no sushi on Fridays, and certainly no sneaky Haegen-Daaz ice cream orgies late at night.
I’m getting hungry just writing about these guilty pleasures, and chances are you are, too, which is due to the fact that our bodies are hard-wired to like this kind of food. The problem is it used to be a very rare treat back in the palaeolithic, whereas now there’s sugar everywhere, and our bodies cannot deal with such quantities of the stuff – hence diabetes, obesity, cardio-vascular diseases; the list goes on and on.
The physical effects of switching to paleo are interesting for another reason too, because after a while – anything from a few days to a few weeks – the body goes into a state where it stops craving carbs and starts using fat as its prime source of fuel. This will supposedly make you much more efficient in long distance races, as the body’s supply of fat is vastly bigger than its stores of sugar (the difference between your muffin top and the muffin you just ate, if you will).
Now, I experimented with this prior to running Ultravasan, but chickened out during the race. But my triathlon is coming up, and if I can do that without craving sugar then this diet must be the real McCoy.
As always, there will be an update afterwards to account for how I did during the challenge – the practical aspects of it as well as any changes to my physique/performance. Now, what’s the best way to cook mastodon for breakfast?
————-
*This sounds like an excellent idea to me, particularly since some studies show dementia to be caused by an accumulated inability to break down sugar, similar to diabetes, and I really don’t want to go down that path.
It’s fair to say the year ended on
