Can i drink flavored water while fasting

Women have been taught the importance of drinking water, especially when dieting, and wonder whether water is allowed when fasting.

“YES MA’AM!” 

Water is on the “allowed” beverages list and plays a pivotal role in your intermittent fasting success.

How water supports the body

It is crucial when fasting, especially when doing prolonged fasting, to always stay hydrated. Our body needs water for survival, but it is also essential for carrying nutrients and oxygen to the body’s cells, preventing constipation, and helping with digestion (1). 

A recommended diet focused on high fiber foods, fats and protein may contribute to digestive discomfort when starting your new intermittent fasting eating schedule. Proper hydration supports the digestive system. 

It also normalizes blood pressure, regulates body temperature, and maintains electrolyte balance (1).

Factors that influence water needs

Can i drink flavored water while fasting

If you don’t drink enough water daily, you risk becoming dehydrated. Gauging how much water you need each day needs to factor in the following:

1. Frequency and level of physical activity

Increased amounts and intensity of exercise performed require greater hydration, especially when exercising on a fasted stomach.

2. Environmental factors

Living in dry or humid areas drinking water all the time is suggested.

3. Overall health

Illness, diarrhea, medications contribute to dehydration and can lead to constipation. Drink plenty of water.

4. Pregnancy & Breastfeeding

Because the body is losing fluids quickly when pregnant or breastfeeding, it is vital to keep fluid intake high.

How much water should you drink daily?

There are different recommendations for how much water you should consume every day. You can use these suggestions as a starting point for determining how much water or other liquids you should drink while considering the above factors (2).

Note: Twenty percent of water intake can come from high water content fruits and vegetables such as celery and watermelon (2).

Some recommendations are:

  • Drink half your weight in ounces. If you weigh 150 pounds, you need to drink 75 ounces of liquid.
  • Drink 6-8 cups of water per day.
  • Drink a milliliter of liquid for every calorie consumed. For women on a 2000 calorie diet, that would be drinking 2 liters of liquid (2).
  • Drink 2.7 milliliters of liquids per day for women (2).

The best plan to figure out how much water you need is to pay attention to your body and stay hydrated.

You might already know that you can't eat anything during certain times of your fasting diet. But what's less clear is what you can drink when doing intermittent fasting.

Although you have to completely abstain from food during your fasting window, there are several beverage options that won't break your fast. Here's what you can drink while fasting, along with the beverages to avoid and tips to get your intermittent fasting diet started.

Tip

During intermittent fasting, water is the best beverage choice. Black coffee, unsweetened tea and certain flavored waters are also options.

The Basics of Intermittent Fasting

Intermittent fasting is more than just not eating. The goal isn't calorie restriction — it's giving your body a break from food so that it can focus its energy on cleansing, rather than digesting.

Your body contains proteins and other structures that constantly become dysfunctional or die, according to the Walter and Eliza Hall Institute of Medical Research (WEHI). This isn't a bad thing — it's a necessary process for optimal health.

Enter a process called autophagy. Autophagy is a form of cellular cleansing where the body marks damaged parts of cells and unused proteins as potentially harmful. Once your body gets this message, the damaged parts are cleared out, according to February 2018 research in ​Obesity​.

However, if autophagy is never initiated, dead or dysfunctional cells can accumulate in the body, which can lead to diseases like lupus, type 1 diabetes and cancer, per the WEHI. Fortunately, fasting can trigger the cleansing process, per the ​Obesity​ research.

There are many different fasting patterns to pick from, but all of them involve eating during specific windows of the day and then abstaining from food otherwise, according to Johns Hopkins Medicine. For instance, the popular 16:8 diet provides an eight-hour eating period followed by 16 hours of fasting.

What Can You Drink While Intermittent Fasting?

Now that you understand the basics of fasting diets, you may be wondering what can you drink while fasting. Here's a breakdown:

1. Water

The best choice is always water, according to Johns Hopkins Medicine. Your water can be plain or carbonated, as long as there's no added sugar.

Staying hydrated helps curb hunger, which may make it easier to stick to your fasting diet, per Johns Hopkins University. There are also other benefits to drinking water, including:

  • It can help lubricate your joints
  • It can help regulate your body temperature
  • It supports digestion
  • It flushes waste from the body
  • It nourishes your cells

How Much Water Should You Drink?

Use this calculation to determine how much water you should drink in a day:

Body weight (in pounds) ​÷​ 2 = minimum ounces of water you should drink per day.

2. Certain Flavored Waters

You can drink some types of flavored water while fasting, including carbonated or seltzer water.

But make sure you're diligent about reading labels. While true seltzer water doesn't have any added sweeteners, some flavored water drinks do, so read the ingredient lists and avoid anything with added sugar or artificial sweeteners. Even water flavored with natural no-calorie sweeteners like stevia may kick-start a sugar craving, per Harvard Health Publishing, which may make it harder for you to stick to your fast.

Accordingly, choose plain seltzer water or waters with natural flavors or fruit essences only. You can even do it yourself by adding fresh lemon to a glass of water.

3. Tea

You can also add flavor to your water by brewing a cup of tea during a fasting session, according to Johns Hopkins Medicine. Just make sure not to add any sugar, milk or cream to your cup.

4. Black Coffee

Black coffee won't break your fast or take you out of ketosis. In fact, according to a January 2017 review in the ​Journal of Basic and Clinical Physiology and Pharmacology​, caffeine may even increase your metabolism, which could help promote weight loss. Black coffee also helps curb your appetite, which can make getting through your fast more manageable.

But it's important that it's black. If you add cream, milk and/or sugar to your coffee, you'll break your fast.

And although black coffee is OK to drink while intermittent fasting, try not to go overboard. Too much coffee can leave you feeling jittery or irritable, especially if you're sensitive to caffeine, per the Mayo Clinic. Drinking coffee late in the day can also affect the quality of your sleep.

Tip

To avoid caffeine side effects, stick to the expert-recommended upper limit of four cups of coffee per day.

5. Apple Cider Vinegar

Diluting a small amount of apple cider vinegar in a cup of water won't break your fast. In fact, it might actually be a good idea — the tonic may help support weight loss and lower blood sugar, according to the Cleveland Clinic. However, more research is needed to better establish apple cider vinegar's effect on weight.

Make sure to dilute it in water before drinking it, though. Apple cider vinegar is highly acidic and can irritate your throat if you drink it straight, per the Mayo Clinic.

Drinks to Avoid While Fasting

Because of the massive amount of sugar that Americans eat on average, many people have become dependent on glucose for energy. When you eat a lot of sugar and that sugar isn't utilized for energy, your body breaks it down and eventually stores it as body fat, per UC Berkeley. In addition, the refined sugar found in most beverages digests quickly, spiking both your blood sugar and your insulin levels.

Sugar is also addictive. Indeed, a July 2013 review in ​Current Opinion in Clinical Nutrition and Metabolic Care​ found that sugar and sweetened beverages and foods induce reward and craving responses in the brain that are comparable to the responses triggered by addictive drugs, which continue the cycle.

As a result, it's best to avoid sugary drinks that can break a fast, including:

  • Soda
  • Lemonade
  • Fruit juices
  • Gatorade
  • Sweetened iced tea
  • Kombucha

Can You Drink Diet Soda, Gatorade Zero or Propel While Fasting?

Drinks like diet soda, Gatorade Zero and Propel don't have sugar or calories, so they may seem OK for fasting.

But it’s not that simple. These drinks — and similar flavored water products like Mio — contain artificial sweeteners, which can increase sugar cravings and make fasting more challenging, per Harvard Health Publishing. Accordingly, it's best to skip these beverages while you're fasting.

What Can You Eat?

During your fasting window, you can drink as many of the approved beverages as you want, but you can't eat anything. Eating provides calories and starts digestion, both of which break your fast.

But when your fasting period ends and you enter your feeding window, it's best to make food choices that keep your blood sugar levels stable. Although there's no specific dietary recommendation when intermittent fasting, many people choose to combine it with a low-carb, high-fat ketogenic diet.

Keto-friendly foods include:

  • Nuts
  • Seeds
  • Vegetables
  • Avocado
  • Olives
  • Meat
  • Fish

At the same time, it's best to limit or avoid high-carb or high-sugar foods like:

  • Whole grains like whole-wheat bread, oatmeal and brown rice
  • Most fruits
  • Starchy vegetables like potatoes
  • Sugary, processed foods like baked goods or soda

Fasting and Weight Loss

Intermittent fasting isn't a regimen built around limiting calories (although it's possible that your calorie intake will be restricted naturally because you're going a period of time without eating), but it can promote weight loss in other ways.

For one, fasting gives your metabolism an overhaul, according to the Harvard T.H. Chan School of Public Health. It works on the same principles as a ketogenic diet. By restricting food (and carbohydrates), you'll switch your body from burning glucose for energy to burning stored body fat.

According to an October 2014 study in ​Translational Research​, intermittent fasting can reduce your weight by 3 to 8 percent over three to 24 weeks. A December 2015 review in ​Molecular and Cellular Endocrinology​ echoed those results by finding that, on average, participants following a fasting diet lost between 7 and 11 pounds in 10 weeks.

Establishing an Intermittent Fasting Plan

So, what's the ideal way to design an intermittent fasting plan? It depends on your schedule and what works best for you, but a good template to start is:

Can you drink flavored drinks while fasting?

Avoid drinking sugary drinks such as juices or fizzy drinks during the fasting window. Diet soft drinks or flavoured waters are not recommended, too, as they provoke an insulin response in the body. You should avoid drinking coconut water as well, as it contains carbohydrates and can break the fast.

Can you drink sugar free flavored water when fasting?

Drinks with calories higher than single digits can break your fast and undo your effort. Even some non-caloric drinks, such as diet sodas, flavored waters, or anything containing artificial sweeteners, can provoke the insulin response and interfere with your fast.

Can you drink sparkling flavored water while fasting?

Carbonated Drinks Carbonated drinks WILL NOT break your fast - CONTINGENT on the fact that it is naturally favoured AND contains 0 calories. Carbonated flavoured water is great to drink while fasting in order to help you feel full and satiated.

Can you drink fruit infused water while fasting?

Tip: Simply adding fruit to your water won't break your fast, since only the essence will be released, not the juices. Try out strawberry infused water, grapefruit infused water or cardamom infused water for some added health benefits! You can also add fresh herbs and spices to give your water even more of a boost.
