How Our Modern Diet Makes Fasting Much Harder Than It Should Be

By Jay Richards Published on February 24, 2018

This is the sixth piece in a series on fasting. Read the entire series here.

We’ve tackled all the obstacles to real fasting except the … main one. For most of us, it seems too hard. Unless you’re from, say, Crete or Saudi Arabia, you probably think, “I can’t do it: I need to eat every four hours. If I fast, I’ll be so miserable I won’t be able to focus on anything else. And then I’ll be so hangry a family member might get buried in the backyard. How can that bring me closer to God?”

These aren’t crazy thoughts. We’ve all missed a meal and felt famished. We search in panic for the fastest relief we can find — Pringles, M&Ms, Krispy Kremes. Just imagine how bad it would be if we missed two or three meals in a row! First-degree murder starts to seem possible.

Not Normal

What you may not realize is that this is not normal. At least it’s not normal for humans historically. If you’re like most people these days, what and how you eat is without precedent in history. Our way of eating creates a near-constant need for food, preferably carb-rich. Rather than moving from a fasted to a fed state and then back to a fasted state, we stay in the fed state for almost all of our waking hours. That’s not how God designed our bodies to work best. In fact, if God designed us that way, the human race would have gone extinct long before we reached our present age of food abundance.

A Sacrifice, Not Torture

Fasting is meant to be a sacrifice. It’s not meant to be agony. Think of Jesus’ words, “My yoke is easy and my burden is light.” (Matthew 11:30) We’re supposed to bear that yoke and burden daily. Do people attack you for your faith on Twitter? Join the club. Do you have to resist temptation every day? Welcome to the human race. Do you get distracted when you try to pray more than fifteen minutes at a time? Keep trying.

If daily prayer gave you migraines and nausea, that would not be a sign that you should try harder. It would be a sign that you’re doing it wrong.

These are the burdens we’re supposed to bear.

But if daily prayer gave you migraines and nausea, that would not be a sign that you should try harder. It would be a sign that you’re doing it wrong.

Ditto for fasting.


We are victims of abundance. Few of us know the pangs of true hunger. What we feel when it’s time for lunch is mostly due to habit. We’re like Pavlov’s dog who salivated when he heard the bell that he had learned to associate with food.Fasting for Body and Soul Jay Richards 2 - 600

Does that mean modern farming and technology is bad and we should all return to caves — or at least to a medieval village — and starve ourselves during the long winter? No. It just means that our abundance has costs that we need to mitigate.

We should thank God that few people in developed countries starve or die from food-borne disease. We should also thank God that we spend far less of our time and money to get food than our grandparents did.

But there’s a non-bright side to this story. Some of it is due to abundance but some is due to bad information.

Abundance Plus Bad Information

Here’s a short summary of our problem:

  1. Authorities have told us that dietary fat is bad, and animal fat is super-bad.
  2. When government went on its anti-fat campaign in the seventies, food companies responded with scads of “low fat” options. To cover the tasteless cardboard that resulted, they added lots of sugar.
  3. We now get most of our calories from carbohydrates.
  4. We consume a lot of highly processed and refined carbohydrates. That includes stuff we think is good for us. Our bodies turn this to sugar.
  5. Man has spent thousands of years selectively breeding fruits and starches to make them sweeter and easier to eat and digest. Check out these pictures of wild corn and bananas. They look nothing like the ones we eat. (But note that most of this happened long before the modern obesity and Type II diabetes epidemic.)
  6. We extract sugar from its natural matrix, drink it, crystalize it, and add it to most of what we eat. It’s in 74% of the packaged food in the supermarket. Just try to find ketchup with no sugar in it. Most of us are sugar addicts. And our body reacts like an addict when we go too long without it.
  7. We eat heaps of sugar, about 22 teaspoons a day on average — a hundred pounds a year! That’s fifty times more than the average in 1700, ten times more than in 1800, and twice what it was in 1900. Just since 1977, when the government launched its crusade against food fat, Americans have swelled their intake of sugar by 30%. We’ve also swelled our ankles and bellies. For comparison, you can only keep about 1 teaspoon of sugar in your blood stream. It’s toxic at much higher levels. So, when blood sugar goes up, the pancreas releases insulin, a sort of gatekeeper that sends signals to parts of your body, such as your liver and muscles, to store this sugar and get it out of the blood. But your muscles and liver can hold only so much. When they’re full, the liver starts converting and storing the sugars as fat.
  8. Finally, we eat too often, rather than switching between feeding and fasting states.

Together, these ingredients make real fasting far too painful for most people to endure.

Fasting By Choice Rather Than Necessity

If you want to make fasting part of your lifestyle, these facts are like dyspeptic fat trolls guarding the entrance to the Promised Land. In earlier centuries, people fasted in part because they had to. They didn’t have Froot Loops on hand every minute of every day. Nor did they need constant infusions of sugar like we do.

This means we have to go out of our way to cultivate a fasting lifestyle.

The Good News

But there’s good news. It’s not that hard to take out the trolls and slip past them.

You see, (1) is false. Natural dietary fat, including animal fat, is your friend. We should reject the recent shift to low fat and high sugar foods.

Once you adjust to this, it takes just a little effort and forethought to overcome (3) – (8) and make fasting (and a little feasting) a permanent part of our lifestyle.

Next, I pinkie promise that I’ll finally start to explain how to ease into and then maintain a fasting lifestyle. And I promise that we’ll discuss the benefits of fasting before Holy Week starts.
