1. It’s FREE. Diets, especially fad diets, come with specialized foodstuffs that taste only vaguely edible and cost more than actual food. There’s often a subscription-only service to a website, an app, a community. The only thing you need for fasting is some salt to replenish electrolytes.
2. Simplicity. There’s nothing to keep track of. No calories, no carbs, no macros to count. There’s no list of foods to reference.
3. Diabetes reversal without drugs. I’m not that kind of doctor, so don’t take medical advice from me. Those wishing to find out more can check out Dr. Jason Fung’s book The Diabetes Code: Prevent and Reverse Type 2 Diabetes Naturally.
4. Increased energy. This sounds counterintuitive, but it’s true. If think about fasting, you’re probably imagining starvation. And when you’re starving, your body will conserve energy so you’ll feel tired and slow, right? Not quite. Imagine if that happened every time our ancestors couldn’t find food for a few days. We wouldn’t exist today. Instead, fasting increases energy — it’s that extra boost we need to get out and hunt some food.
5. Lower food costs. Common fasting protocols recommend fasting for 2-3 days a week. Or eating only during an “eating window” of up to 8 hours a day. Even if you try, it’s hard to cram the same amounts of food you eat when not fasting into a fasting regimen. Which brings us to…
6. Decreased hunger. This also seems counterintuitive, doesn’t it? It was a revelation to me that hunger doesn’t increase linearly or exponentially the longer you don’t eat. Hunger is controlled by hormones, and is cyclical. I’m sure it’s happened to you: you were hungry but too busy to stop and eat. After 10 minutes or so, you weren’t hungry anymore. It’s the same when fasting. You’ll get hungry in response to cues like normal meal times or food smells, but if you don’t eat, it goes away. For those who do extended fasts, hunger will generally go away entirely as the body switches to ketosis (burning fat for fuel).
7. Flexibility. There are many ways to fast. Alternate day, 2 days a week, eating windows, extended fasts a few times a year. Since there are no special foods, you can easily bring fasting with you on vacation. If you’re on a road trip and the only food available is unappetizing, like day-old pizza from the gas station, you can fast.
8. More free time. How much time does it take to do meal planning, grocery shopping, cooking, cleaning up? Even going out for each meal doesn’t save as much time as fasting. If we estimate that 2 hours per day are spent preparing and eating food, then fasting 2 days a week saves you 4 hours. How much is your time worth to you?
9. Improved mood. No, this can’t be right. Don’t people get “hangry”? Sure, but it’s a response to wild swings in blood sugar (which happen after eating high-carb foods without the balance of fiber to slow down the release of glucose into the blood stream, and the concomitant flood of insulin which crashes blood sugar levels). When you don’t eat, your blood sugar is low, but stable. No wild swings in blood sugar means no accompanying swings in mood.
10. Less bloating. As mentioned in 9, fasting keeps blood sugar low. In turn, this keeps insulin levels down. Insulin causes water retention (because it causes our bodies to retain sodium).
There are some folks who shouldn’t fast, but for the vast majority of us, it’s a good idea. This is not, in any way, a sponsored post, but a lot of great information about fasting can be found here.
