The Ultimate Guide to Preventing Bad Breath While Intermittent Fasting

Bad Breath Intermittent Fasting: A Comprehensive Guide

Intermittent fasting has become an increasingly popular way to lose weight and improve overall health. However, many people don’t realize that this type of fasting can also lead to bad breath. Fortunately, there are steps that can be taken to reduce the risk of bad breath while fasting and still reap the benefits of this diet.

Practice Good Oral Hygiene

One of the most important steps to take in order to reduce bad breath associated with intermittent fasting is to practice good oral hygiene. This includes brushing your teeth at least twice a day, flossing daily, using a tongue scraper, and rinsing your mouth with mouthwash. Additionally, it’s important to eat a healthy diet, as this can help reduce the risk of bad breath. Chewing gum can also help, since it increases the flow of saliva to the mouth and can help manage bad breath when fasting.

When breaking your fast, it’s important to avoid certain foods that can cause bad breath. Onions, garlic, and spices can all contribute to bad breath, so it’s best to avoid these foods while fasting.

Stay Hydrated

Staying hydrated is essential while fasting, as it can help reduce bad breath. It’s recommended to drink at least 2-3 liters of water per day to help keep your breath fresh. Additionally, it’s important to avoid salt, sugar, and caffeine during non-fasting hours. These can all contribute to dehydration and bad breath.

Why Does Intermittent Fasting and the Keto Diet Cause Bad Breath?

When following the ketogenic diet and intermittent fasting, the body enters a state of ketosis. This is when the body begins to burn fat for energy instead of carbohydrates. When this happens, the body produces ketones, which are gaseous compounds that can lead to bad breath. Fortunately, this type of bad breath doesn’t always occur and many people don’t notice any change in their breath.

How to Get Rid of Bad Breath While Fasting?

There are several ways to reduce or eliminate bad breath while fasting, such as:

  • Brushing your teeth twice a day
  • Using interdental aids
  • Cleaning your tongue
  • Avoiding certain foods that cause bad breath
  • Drinking lots of water
  • Brushing your tongue
  • Chewing sugar-free gum to increase saliva production
  • Taking Dr. Berg’s Digest Formula

Dr. Berg’s Digest Formula is specifically designed to help reduce bad breath associated with intermittent fasting and the ketogenic diet. This formula contains a blend of enzymes and probiotics that can help reduce the risk of bad breath.

In addition to these tips, it’s also important to get enough sleep and exercise, as these can help reduce the risk of bad breath. Taking breaks from fasting can also help, as this can give your body the opportunity to rest and recover.


Bad breath can be a side effect of intermittent fasting and the ketogenic diet, but it doesn’t have to be. By practicing good oral hygiene, staying hydrated, avoiding certain foods, and taking Dr. Berg’s Digest Formula, you can reduce the risk of bad breath while still reaping the benefits of this type of diet.

What steps can I take to ensure I don’t have bad breath while doing intermittent fasting?

Avoiding tobacco products.
Drinking plenty of water.
Visiting your dentist regularly for a professional cleaning.

What causes my breath to smell unpleasant when I am not eating?

When fasting, our saliva production decreases, leading to a lack of defense against the bacteria in our mouths which can cause bad breath. Once you break your fast, your salivary glands will kick back into gear and start working to protect you once again.

Is it typical to have foul breath when one has not eaten?

Not eating can lead to bad breath as it decreases the amount of saliva that washes away bacteria from your teeth, tongue, and gums.
