Can You Drink Water While Intermittent Fasting

If you drink Coffee while WATER FASTING, you are NOT Water Fasting

As we already covered at the beginning yes, you can drink water during intermittent fasting. Staying hydrated is an important rule of doing intermittent fasting in the right way. Basically, if youre not drinking water while fasting, its dry fasting which entails a whole set of new rules and precautions.

Your intermittent fasting will go a lot smoother if you drink enough water and you will avoid or at least lessen many of the intermittent fasting side effects.

But how much is enough water during intermittent fasting?

There are no set rules. Generally, men require around 3.7 liters while women require around 2.7 liters of water in a day.About 20% of this amount is absorbed from food.

But the actual requirement of water for a particular person depends on the age, sex, weight, activity level, current season and the general climate of the place you live in.

Also, you should take into account that when doing intermittent fasting youre not eating during certain periods of the day so youre not absorbing any water from food. Thus you should drink more water to provide the valuable juice of life to your body.

Not to confuse with all the calculations and exceptions, a simple rule of thumb to follow would be the 8 x 8 which means that you should consume eight eight-ounce glasses of water every day. If you feel like you need more to feel healthy and energized, add a few more glasses.

What About Dry Fasting

The main exception is dry fasting, which restricts all foods and liquids, including water, for a specific amount of time.

Some people do a dry fast while intermittent fasting.

However, because dry fasting may be linked to dehydration and other health complications, you should talk with a healthcare provider before trying it.


Water does not affect blood sugar or insulin levels and is usually permitted during intermittent fasting. Dry fasting is the main type of fasting that doesnt allow water.

What Its Like To Water Fast At Siddhayatan

Siddhayatan is in Nowhere, Texas. Truly, it is miles from anything, and you cannot use your Uber or Lyft app from there to sneak out and get food in a moment of weakness.

Its insanely cheap, maybe the cost of a Motel 6.

It makes sense, considering theyre feeding you nothing, and you might be sharing a bathroom or staying in a room with no drywall, and your only form of light is a naked lightbulb.

I could go to True North in California where theyll medically supervise me, and the lodgings are really nice.

But heck, while Im facing all my addictions, might as well face my addiction to upper-middle-class luxuries.

I take a sliver of soap and a towel.

I take a $100 Uber from the airport, where you can actually get a ride. You can Uber to the ashram, but not back to the airport.

Later, Ill have a private car company drive me back, but you cant just call them when youre freaking out and wanting food. You can schedule them to pick you up tomorrow.

So, this saves me from my freakouts. I mean, freakouts are by definition short-term.

You see how its the perfect place for extended water fasting? Temptation is completely removed.

Also, you can have a meal there if you find you arent doing well in fasting without food.

You would have to be in a serious crisis to just drop in for lunch, though. First of all, that would be embarrassing.

Youre supposed to give them a heads up because this is the most frugal place youve ever been.

I know, its really Dickensian.

Intermittent Fasting Basics For Beginners

In case you dont already know how fasting works, feel free to check out the complete guide to fasting.

If you want the quick n dirty version, though, Ill explain it briefly just to make sure were on the same page.

So fasting works by restricting when you eat, rather than what you eat.

Its not really a diet.

No food is technically off-limits, so long as you eat reasonable portions and only within a specific window of time each day.

The most popular intermittent fasting schedule is 16:8, where you fast for 16 hours of the day and eat all your days food within the remaining eight consecutive hours.

Keeping things simple, this equates to skipping breakfast, eating lunch around or after 12, and finish your last bite of food for the day around 8 pm.

Now that you know what fasting is lets talk more about the fasting window.

Keto And Intermittent Fasting For Beginners

Lose Help Water Can Drinking Fast You Weight How

For most beginners, getting started with intermittent fasting can help with fat loss, disease prevention and thereby increase longevity. And all that comes with minimal side effects.

If youve ever eaten dinner, slept in, and not eaten until lunch the next day, then youve fasted using the 16/8 schedule before.

You may even know people who are simply not hungry in the morning and instinctively do 16/8 intermittent fasting resulting in excellent fitness. After unlearning to be hungry in the morning, most beginners achieve the best results in intermittent fasting with 16/8.

In addition, the method is flexible and saves time. Nonetheless, you need to keep in mind that intermittent fasting is just an eating pattern and not a complete solution to your diet.

Hence, regardless of which intermittent fasting method you choose, you will get better results with a low-carb diet.

Therefore, more and more people report that a ketogenic diet works wonders for intermittent fasting for a good reason.

Because both fasting and the keto diet are based on reducing insulin, emptying carbohydrate stores, and burning fat through ketosis, they are ideal matches.

since you dont have to spend hours burning your stored carbs first.

Used correctly, intermittent fasting and ketogenic diets can have a massive impact on health and weight loss.

Remember The Orange Juice

In many movies and TV shows, you often see the main actor getting up from the bed and going straight to the fridge for some orange juice. How many of you have done this before? How many of you reached for the perfect sour-sweet ratio to wake you up. Even before the coffee? Well, even though the orange juice is one of unhealthiest options, the good thing about it is the citric acid, vitamin C and some minerals. So, if we exclude the sugar, maybe we can still enjoy this refreshing waking-up effect of orange juice?! Remember, orange essential oil is quite Keto friendly.

Why I Didnt Do My Water Fasting At Home

When water is readily available, it is hard for most people to abstain from it.

I have very little self-discipline. Im not a biohacker, constantly using technology on myself to experiment. Ive never run a race longer than a 10k and dont plan to. I dont have any self-denial fetishes. I dont just do every hard thing, because its a challenge.

Besides being raised Mormon, where we fasted Saturday night to Sunday night one Sunday every month from the age of 8, I have absolutely no reason why fasting for 40 days would be easy for me.

Im one of those people who, if something hurts, or Im hungry, everybody around me is gonna know about it.

In fact, I knew I couldnt successfully water fast at home.

I would start with the best of intentions, Im sure. I might even last a whole day. But, the fridge would be right there 100 steps away. My car would be in the garage. I live just 10 minutes away from food, really good food.

No, wait, its worse than that. Theres a Thai restaurant literally 3 minutes away from my house.

My willpower is nothing when I get ferociously hungry. Im a vegetarian, and frankly, Id eat a t-bone cooked rare if I got hungry enough, maybe even a hot dog.

Rather than deal with all that temptation, I flew to a spiritual retreat in Texas run by Hindu monks and nuns to fast. Its called Siddhayatan.

Can You Drink Water While Fasting For Yom Kippur

Yom Kippur, the Jewish Day of Atonement, falls eight days after Rosh Hashanah, the Jewish New Year. Most notably, the day is observed by living without many humanly pleasures: Observant Jews are not supposed to wear leather or makeup and, most importantly, they are not supposed to eat.

The fast is one of many that occurs in the Jewish calendar year âTisha B’av, a day of mourning a few months earlier is also a fast day â when observers are instructed to deprive themselves of food and drink from sundown on the eve of the holiday to the sunset closing out the holiday.

Fasting is most important before any surgery that requires anesthesia, such as joint replacements, heart surgeries, and more.

Thats because anesthetic drugs can impair your protective airway reflexes, says Jeremy Dennis, MD, a board-certified anesthesiologist and assistant professor of clinical anesthesiology at Yale-New Haven Hospital in New Haven, Connecticut. If you have food or liquid in your stomach during surgery, theres a small risk that some of it could get into your lungs while youre under anesthesia.

While Food And Drink Are Forbidden On Yom Kippur Is Plain Old Water Okay

It depends.

Like everything in Judaism, the ritual observance is up for interpretation and mandated differently by various sects and religious leaders. The elderly, ill or those who are pregnant are instructed not to fast at all, but for those healthy enough to spend the 25-hour fast without food or drink, strict rules do apply.

According to Chabad, a sect of Orthodox Judaism, all eating and drinking is forbidden on Yom Kippur â water included. Many fasting guides recommend drinking extra water in the days leading up to Yom Kippur, to hydrate one’s body in preparation for the water-free fast. Many take this water ban to the extreme, abiding by the rules not to even swallow necessary medications with water and not to use water or mouthwash to even rinse your mouth if it feels dry or uncomfortable.

Reform Judaism, however, takes a more liberal approach when it comes to water on Yom Kippur. While the sect does not encourage the drinking of water while fasting, suggests that “during the fast, if you get dizzy or lightheaded try sitting down for a little while. If the feeling persists, or if you have other worrying symptoms, please drink some water immediately and eat a small amount of food. Judaism does not condone endangering your life in order to fast, even on Yom Kippur.”

Intermittent Fasting Side Effects Beginners May Experience

Most people are used to burning only sugar for energy because of the Western Pattern Diet . Therefore, switching to fat burning for the first time can bring the following symptoms:

  • Headache
  • Nausea
  • Stomach pain

These physical symptoms are also known as the keto flu because the ketogenic diet requires the body to get used to burning fat for energy in the same way.

The trigger for this is the depletion of carbohydrate stores. Before the body can go into ketosis, it preferentially consumes glucose, which comes from glycogen in the liver and skeletal muscles.

Glycogen is a branched multisugar, with about 2-3 grams of water for every gram of carbohydrate.

Since this causes the body to flush out a considerable amount of water and electrolytes, physical symptoms can occur, most notably headaches and dizziness.

However, these disappear permanently once the body is fat-adapted. If you prepare for it, you can also prevent the keto flu while intermittent fasting, even as a beginner.

Intermittent Fasting For Weight Loss

People successfully lose weight with intermittent fasting for a good reason: fasting is the best way to lower insulin levels.

Insulin is responsible for signaling cells to absorb glucose from the bloodstream and store excess energy as fat or glycogen.

Accordingly, researchers can already predict 75% of the gain and loss in overweight people using insulin levels .

Moreover, insulin prevents the breakdown of body fat .

The fasting window stops nutrient intake, lowers insulin levels, and thus ends the bodys storage mode.

Therefore, the body can start to deplete carbohydrate stores. Once they are empty, body fat can be burned for energy production instead.

This mechanism is probably the essential goal of intermittent fasting for most people.

Consequently, our bodies build up fat reserves during times of abundance to draw from this body fat during food shortages.

Because we now eat at all times of the year and around the clock, we gain weight. In contrast, Intermittent Fasting restores the natural balance between eating and fasting.

Accordingly, fasting corrects the hormonal imbalance that causes obesity .

Top 5 Intermittent Fasting Mistakes

Intermittent fasting is a general term for various eating patterns that involve fasting for short periods of time. Unlike a typical weight-loss diet that restricts how much or what you eat, its all about integrating periods of fasting into your day to reap the many proven benefits. These benefits include burning stored body fat for energy instead of being dependant on sugar, feeling less hungry and improving overall health.

I truly believe intermittent fasting is the missing link in our overall health and well-being.
