Fasting is a popular diet trend, but it’s important to pay attention to what you drink during fasting. You may be unknowingly sabotaging your fast with unhealthy drinks that can lead to health complications.

Here are the most common and worst things to drink while you’re fasting. Don’t let the wrong drink get in the way of your healthy lifestyle!

Types of Intermittent Fasting

There are many forms of intermittent fasting, and it’s important to find one that works for you. Here are some popular types of intermittent fasting.

Time-Restricted Eating

Time-restricted eating is a form of intermittent fasting that restricts your eating window to a specific number of hours each day. This eating window may be set as a full 12 hours or reduced to 10 hours, 8 hours, or 6 hours depending on your needs.

The Warrior Diet

While not technically considered intermittent fasting, as little restrictions are placed on what food you eat throughout the day, it still requires specific meal times every day depending on how strenuous your activity levels are during each phase of the day; underfeeding in the first half (4 – 6 hours), then overeating for the second half (2 – 4 hours).

The 5:2 Diet

Also known as ‘The Fast Diet’, this form of intermittent fasting involves 2 ‘fast’ days per week where calorie consumption is restricted to 500-600 calories per day. The rest of the week is usually left open for flexible dieting where you can still eat relatively healthy while adhering to calorie goals.

Alternate Day Fasting

Alternate-day fasting is a type of intermittent fasting that alternates days of calorie restriction with days of eating. It can be done in a variety of ways, but the most popular involves consuming about 500 calories on fasting days and eating normally on non-fasting days.

Water Fasting

Water fasting, also known as water-only fasting or liquid-only fasting, involves abstaining from food and drinking only water. Usually lasting from 1 to 2 days, it can be a way to lose weight and detoxify.

Dry Fasting

Dry fasting eliminates food and water for a specific period of time. This type of fasting is popular in religious traditions and has its roots in ancient times.

Best Things to Drink While Fasting

While many people choose to abstain from eating during a fast, liquids are allowed. Having the right beverage can help you make it through a fast without feeling overly hungry or deprived. Here are some of the best drinks to enjoy while fasting:


The best thing to drink while fasting is water. The benefits of drinking water during fasting include improved energy levels and weight loss. In addition, it promotes autophagy, the process by which your body recycles damaged cells. Aim to drink at least two liters of water or more per day when you are fasting.

Sparkling Water

Sparkling water can be a great choice when you’re fasting. It is calorie-free and contains no sugar, so it won’t break your fast and will keep you hydrated. Sparkling water also helps fill you up, making it easier to resist the temptation of other beverages.

Be sure to check the label for any added sugar or artificial sweeteners, as these can break your fast. Additionally, trends like ‘flavored sparkling waters’ could easily contain hidden sugars and be something to avoid if you are looking for an appropriate beverage while fasting.

Mineral Water

Mineral waters are a good source of calcium, magnesium, and potassium. These minerals are important for overall health and for lowering cholesterol in the blood. However, it is important to choose a brand of mineral water with the proper ratios of these minerals if you are fasting. Mineral water is another hydrating option that won’t break your fast.

Lemon Water

Many people who fast for religious or dietary reasons choose between drinking only water or drinking a combination of tea or coffee, with or without lemon water added. While many fasting traditions vary slightly in terms of what beverages are allowed, lemon water is typically considered an appropriate accompaniment to any protocol. This is largely due to its ability to provide hydration and some flavor without compromising the process of abstaining from food and other beverages.

Lemon water can help keep your body’s pH balance in check by providing needed electrolytes. It can also stimulate digestion and make it easier for the body to absorb other nutrients when you choose to break your fast. Another benefit of lemon water is that it has natural cleansing properties; this helps rehydrate cells and flush out toxins along with extra sodium. Certain types of fasting — significantly intermittent fasting — also require a boost of energy; as lemons are full of vitamins C and B, they provide that extra boost alongside the hydration benefits.

When it comes to drinks that should be avoided while fasting, anything with a lot of sugar or caffeine is best omitted from your diet—both during the fast itself, as well as during periods in which you are not fasting at all. While coffee can still be consumed for its antioxidant benefits in moderate amounts during some types of fasting protocols, very high levels should be avoided because they stimulate hunger hormones, causing you to feel an intense craving for food even while trying not to eat. Carbonated beverages like soda should also be avoided since they have no nutritional value anyway; plus carbonation can cause bloating and stomach discomfort while compromising the process of cleansing through a fast.

Black Coffee

If you are fasting, you can drink black coffee in moderation. Make sure you don’t consume any sugar, milk, or cream in the coffee, as it will break your fast. Coffee can help you lose weight if you drink it in moderation. It’s also an effective way to keep your metabolism in high gear and increase ketone levels. But, drinking too much coffee can interfere with the benefits of intermittent fasting.


Many people believe that consuming tea during a fast will break your fast, but this isn’t the case. In fact, it can actually help you maintain your diet and boost the results of your fasting. However, make sure you drink tea without sugar, cream, and milk. Some of the best tea you can drink while fasting is hibiscus tea, peppermint tea, herbal tea, etc.

Apple Cider Vinegar

Yes, you can drink apple cider vinegar while fasting. However, make sure that you don’t exceed the recommended dosage. Generally speaking, 1-2 tablespoons of ACV per day is sufficient. ACV’s acetic acid helps to balance blood sugar levels and normalize high glucose levels at night.

Worst Things to Drink While Fasting

When it comes to fasting, it’s important to consume only drinks and foods that won’t break the fast. Most liquids are allowed, as long as they don’t have any calories or added nutrients. In general, the worst things you can drink while fasting are those that contain calories or break your fast without providing any health benefits.

Alcoholic beverages should be avoided during fasting because they will break the fast. All types of alcohol contain calories and can contribute to dehydration, making them unsuitable for fasting. Any type of sugary beverage (including soft drinks, sports drinks, cordials, etc.) also breaks your fast as it contains fructose and other sugars which will take your body out of a fasted state.

Coffee and tea are generally allowed during intermittent fasting; however they do contain small amounts of caffeine which may affect hunger levels. Keep in mind that adding milk or cream to coffee may mean you are drinking something with more calories than you intend so focus on having black coffee or tea if possible when you’re fasting. Try flavored waters if you need a caffeine hit – these have no calories and generally won’t affect your metabolism in any way which makes them safe for intermittent fasting protocols.

Energy drinks should also be avoided while fasting because of their high sugar content and added stimulants like caffeine which can disrupt the health goals associated with fasting such as improved insulin sensitivity and fat oxidation. In addition, many energy drinks also contain food dyes that can interfere with the body’s natural processes such as digestion or hormones – further amplifying the negative effects they can have while someone is in a fasted state.

Most importantly, the DoFasting Intermittent Fasting App helps its users identify which drinks they should abstain from while fasting – because not all beverages are created equal! For example, even though black coffee is okay while intermittently fasting, sugary drinks like soda or juice can stall your progress and weaken any potential health benefits of intermittent fasting. Therefore it’s important to know what beverages you should avoid while in the fasted state so that your body can receive beneficial fatty acids that could contribute to better overall health. Sticking with water and unsweetened tea is recommended during any type of fasted state.


In conclusion, it’s important to think carefully and make the best choices depending on your situation when it comes to drinking beverages while fasting. While staying well-hydrated is essential, some drinks can inhibit the body’s ability to burn fat effectively and disrupt hormone balance. Be sure to choose beverages that are unsweetened, free of calories and low in sugar.

Remember that coffee and tea can be great fasting aids as long as they are consumed without creamers or added sweeteners. Additionally, certain herbal teas can help you stay hydrated without breaking your fast.
