As I write this, I am on a 5-day water (and salt) fast. It is something I now do twice a year, down from four times a few years ago. Why would anyone willingly and repeatedly do this?!
The most obvious answer some might jump to is weight loss. However, my experience has shown fasting is not a very good way to do this. Putting aside the fact that I have no desire to drop any weight, the first time I did such a fast I lost slightly less weight than I did when traveling around Italy for a week gorging on pasta, pizza, and gelato. Granted I have no idea how that is possible, but one way of losing weight was a lot more fun, I will tell you that much!
However, in both cases, a week or two later I was back to my starting weight. The weight shed does not stay off. If weight loss is your goal, you are far better off eating and exercising in a long-term sustainable way, otherwise your weight will just yoyo back and forth.
But if isn’t about weight control, why fast? There are myriad health benefits attributed to fasting, from reducing inflammation, to life extension, to boosting brain function, and more. These were the benefits that initially got me to try fasting. Particularly when it comes to inflammation and little niggling injuries, I do feel a difference.
Fasting has also provided an ancillary benefit I am not sure I expected going in: it helps show me what I am capable of. Before I began fasting, if my stomach grumbled, I was a slave to it. I couldn’t work out; I wasn’t properly fueled! I couldn’t do my best mental work; I was undernourished! Believing I always needed food accessible to me, I just accepted that I had no control over whether I became “hangry.”
Now? Now I know this was all in my head. I have gone to the gym having not eaten for five days straight and lifted heavier than before I began the fast. I have cranked through work of higher quality and at a greater throughput having consumed nothing but water and salts for days on end. My mind and my body were always capable of these things. My mind was also what was holding me back.
This same lesson applies far beyond fasting. The idea of deliberately testing our limits, of pushing ourselves not only to show us what we are capable of, but also to give us greater immunity to the vagaries of life is far from new. Two millennia ago, Seneca wrote to Lucilius:
Set aside a certain number of days, during which you shall be content with the scantiest and cheapest fare, with coarse and rough dress, saying to yourself the while: “Is this the condition that I feared?” It is precisely in times of immunity from care that the soul should toughen itself beforehand for occasions of greater stress, and it is while Fortune is kind that it should fortify itself against her violence…If you would not have a man flinch when the crisis comes, train him before it comes.
[…]
Let the pallet be a real one, and the coarse cloak; let the bread be hard and grimy. Endure all this for three or four days at a time, sometimes for more, so that it may be a test of yourself instead of a mere hobby. Then, I assure you, my dear Lucilius, you will leap for joy when filled with a pennyworth of food, and you will understand that a man’s peace of mind does not depend upon Fortune; for, even when angry she grants enough for our needs.
How often have you felt compelled to do something you know you don’t want to do because of your fear of what might happen if you don’t? The most obvious example comes down to material wants and needs. As we buy a bigger house, and fill it with more things, we increase our expectation of what we “need” to be happy.
Rubbish says Seneca. Test yourself. Deprive yourself of these things and you will find you are quite capable of living, and even living happily without them. Sure, it is easier if you never develop a taste for these things in the first place. As with quitting smoking, there may be some withdrawals, but you can do it. You are stronger and far more capable than you realize.
I am not saying anyone else should go and stop eating for five days. I am suggesting you have more room to test yourself than you are likely taking advantage of today. Is it cold out today? Maybe go without the coat to prove to yourself you can get by just fine, though perhaps with a bit of a chill, without that extra layer. Can’t get through the morning without your daily cup of coffee? Take a month off to show yourself you are not a slave to any substance. You can still decide you want to go back after the month is out, but proving you can get by just fine without it puts you in far more control when unforeseen circumstances crop up that may make it impossible to get your normal java fix.
None of this needs to be permanent. The important thing is that you show yourself that you can get by without these things you believed you needed rather than just wanted. At that point you can decide if you want to keep them habitually in your life or not. You are not dependent on them; you have proven that to yourself. You are using them; they are not using you.
Test yourself. Is this the condition you feared? Fear no more. You can do hard things.
