The other day, my husband pointed out an article that 'would interest me'. He was right – as usual.
The article was called 'Do you make too many decisions?', posted at the smart and thought-provoking Farnam Street blog.
Decisions, Decisions ...
Now, before you think this was his subtle way of calling me bossy, you might want to read the article. It deals with the decision density of modern life, and how each decision takes mental effort, thus reducing the amount of energy left for stamina, persistence and willpower.
This leads to what is called 'decision fatigue', which is described in detail in this New York Times article and in Roy F. Baumeister's and John Tierney's book: 'Willpower: Rediscovering the Greatest Human Strength' that's coming out in a few days (September 1st, 2011).
One of the most interesting takeaways of the articles for me was the discovery that glucose plays a vital role in willpower. It explains why dieting is a particularly difficult test of self-control.
The Catch-22 of Dieting ...
Seriously, everyone who's ever been on a diet knows this - myself included. Even people with very strong willpower in other aspects of their lives feel they're lacking when it comes to dieting.
We start the day with the best of intentions, manage to resist the first temptations thrown at us, but each of these brave acts takes up mental energy and lowers our willpower. Towards the end of the day, willpower simply runs out. To replenish it, we'd have to give our brain glucose, hence the sugar cravings.
So here it is, the catch-22 of dieting:
1. We need willpower to resist eating.
2. We need to eat in order to have willpower.
Now, the good news is that, once an explanation has been found, one can start looking for solutions to a problem. *Cheer*.
Dieting and Decision Fatigue ...
Reading the article at Farnham Street came at exactly the right time. Over the past year I'd gained a few pounds, and now the summer holidays have come to an end, I'm working on losing them again. Being a foodie and a wine enthusiast, I have to stay alert. But that's okay; the alternative is worse.
I've written extensively about weight management before in my 'Manage your body weight - the green way' series, but here's a summary of what I'm doing at the moment, in case anybody's looking for inspiration / motivation after some summer indulgence and wants to join in:
1. I register everything I'm eating at http://www.fitday.com - it's very little work and it gives me an overview of how I'm doing. It's easy to miscalculate or lose track of the calories and nutrients you're consuming if you just play it by ear. A reliable food diary shows the facts, which helps by taking away some of the strain of having to make the right decision every time.
2. I manage my environment to reduce temptation, which leaves me with more willpower for when it matters. This means: if I can't or shouldn't eat it, I don't have it in the house. In short: no candy, no crisps, ... and instead plenty of fresh vegetables, low-calorie meals in the freezer, easy snacks like my favourite fruits, nuts, Greek yoghurt, dark chocolate (70% cocoa or more), lemons & soda water (to make stevia-sweetened lemonade), etc.
3. I eat smaller meals but more often: 5 to 6 times a day. (I aim for 6, usually manage 5.) Being able to eat on a regular basis reduces the burden on your willpower.
4. No sugar, except for the bit that's in my daily piece of dark, bitter chocolate, which isn't much, and a bit of grape sugar (dextrose) - see under number 5.
5. My new favourite emergency trick (after reading the articles I mentioned above): if I get a really bad sugar craving and I'm about to give in, I take a teaspoon of grape sugar / dextrose. It works for me, but that doesn't mean it's good for everybody. If you want to do this, do it wisely. Glucose affects your blood sugar levels, so if you're a diabetic, this is probably a really bad idea.
Also, know that 5 grams of dextrose amounts to about 20 calories, so don't exaggerate, register the calories and don't fool yourself into thinking it's good for you. If you focus on eating healthily, you should get a steady release of glucose from the other foods you're eating, so this is just a fix for the most difficult moments.
If you're wondering why I use dextrose instead of normal sugar, cane sugar or any of the other sugar varieties out there: it's because grape sugar / dextrose is 100% glucose. Regular sugar, cane sugar and the others also contain fructose, which is to be avoided. (Read this article / watch the video if you want to know more.)
