I started my fast on 9 November and am ending it tomorrow morning on 9 December. This is my ninth fast over 10 days in length spanning 7 years. It is my first fast over 20 days in length. Overall it has been easy, although I have recently been fantasizing about how wonderful it would be to not have a tongue.
Ten years ago, I could eat what I wanted and activity at work would keep me slim. In the last 2 or 3 years, that suddenly stopped happening, and I've been in a bit of denial about it. I got a rather alarming physical last month and decided it was time to try a longer fast.
I don't claim that any of the points below are original, but they have been touchstones for me through the whole process.
THE GOOD
In short: mission accomplished. In the beginning I was 53 lbs overweight, my blood pressure was 150/95, resting pulse 105, chest 49", waist 39". On my last day, I was 12 lbs overweight, my blood pressure was 109/73, resting pulse 56, chest 43", waist 34". Even with a 10 lb weight bounce coming off the fast, my problems now seem manageable. I'm pondering a shorter, follow-up fast next month to take care of loose ends.
THE BAD
Hands down, my tongue was the worst part of the fast. Since day 17 it has had an odor ranging from sickly sweet to a sweet, rancid putrid odor that has been close to maddening. It wakes me up at night. It dominates my waking thoughts. Leaving it alone doesn't help. Drinking more water doesn't help. Attacking it hourly with things like antiseptics, brushes and scrapers doesn't help.
In a distant second place is sleeplessness. It was more of an annoyance than anything else, but I've noticed that when making calculations, I really need to double-check myself.
SOME OBSERVATIONS
1. Distinguish thinking about food from hunger.
These are two very different things, but the perceived difference always seems to evaporate over time.
2. Keep track of your progress.
When things get trying in the middle of a fast, it's nice to look back and see how much progress you've made. I keep a spreadsheet open with a graph showing my daily weights and notes. This time, since there were some heart/circulatory issues, I kept another spreadsheet that showed how my blood pressure was plumetting as the fast progressed.
3. Keep a clear mental picture of what's left to gain.
As the fast progresses, you'll find your "magic number," how much you typically lose per day after the initial weirdness ends. For me, this was a pound, or about 2 cups (1 pint) of fat. On day 15, it was comforting to think that I expected to lose another 30 cups of fat by the end of the fast. Even on day 25, the prospect of losing another 10 cups was intriguing.
4. Don't avoid being around food.
Smelling, seeing and holding food in your hands while you fast helps you proactively deal with feelings that could lead to binge eating after the fast. That said, you do have to respect the fact that you are a hungry animal. On my latest fast, while stimulating my salivary glands by smelling a bottle of pepperoncinis, I may have turned into a werewolf for a moment.* There's no question that growling and sweating were involved.
I did avoid watching food commercials on TV, they were indeed distressing.
5. Prepare your kitchen.
Throw out anything you don't want to eat after the fast and stock up on the foods you want to eat. If there are problems in the kitchen that sap your enthusiasm for making healthy food, apply some of your fasting energy to solving them. When you get a craving, look for recipes you can make to fulfil it in the future and add them to your repetoire.
I planned out a set of 7 menus for my refeeding period, calculating vitamins, minerals, fiber, and so forth. It seems better to do it ahead of time, and decrease the stress later.
6. Distractions can be useful.
If you can kill a block of time doing something that pushes out thoughts of food, it's a real windfall. On my latest fast, I had to travel by air to another city on days 27 and 28. Worrying about logistics like plane schedules, the rental car and hotel, driving directions and so forth kept my mind busy.
Sometimes you'll forget for an extended period that you're fasting. One thing I particularly hate is deciding that it's time to get something to eat and then remembering that I'm on a fast.
7. After day 21, review the arts.
Nobody would ever refer to me as a particularly emotional or artsy guy. However, late in the fast, I was amazed by the emotional response I could have to music, photos, and even some news stories. Spread your net wide, and you'll likely find some really interesting surprises.
I didn't cry at my father's funeral, but watching a retrospective on the 30th anniversary of John Lennon's death this morning, I was sobbing like a baby. Go figure.
8. Identify and leverage your most powerful motivators.
There is a deep, shadowy layer somewhere in my mind where my fundamental attitudes towards healthy eating, exercise, and fasting dwell. From time to time, I will subconsciously start thinking of fasting as attonement for the sins I committed against my body in my misspent youth. For me, that is not a deep well to draw on for inspiration. If I stay in that mindset, I can't do a long run or a long fast. If instead, I use "this helps me be the best at a job I love" as my underlying motivation, I find I have a surprising perserverence.
