Intermittent Fasting Foods to avoid Constipation and Inflammation

Intermittent Fasting Food to avoid Constipation and Inflammation

Intermittent Fasting ?

Basically, many foods are safe from causing constipation and inflammation. However, during intermittent fasting, it’s important to focus on what and how much you eat. You should also be aware of which foods to avoid during this type of fasting. Now, let’s get to the main point. You should consider the following three major problems: intermittent fasting can help manage SIBO (small intestinal bacterial overgrowth), inflammation, and constipation in several ways.


You know how our digestive system sometimes needs a little extra help? Fasting can be really beneficial for this. It helps improve something called the migrating motor complex (MMC), which is basically our body’s way of moving food through the digestive system. When the MMC isn’t working well, it can lead to issues like Small Intestinal Bacterial Overgrowth (SIBO) or Small Intestinal Fungal Overgrowth (SIFO).

Interestingly, hormone imbalances involving thyroid, cortisol, and sex hormones can also mess with the MMC. Fasting can actually help get these hormones back in balance, which in turn helps the MMC do its job properly.

Besides fasting, there are natural remedies that can boost MMC function. For instance, ginger is a great natural prokinetic agent. There are also supplements containing licorice root, marshmallow root, aloe vera, and slippery elm that can improve MMC function and help treat SIBO and SIFO.


You know how sometimes certain foods just don’t sit right with you? That’s often due to food sensitivities, which can cause inflammation. One cool way to figure out which foods are the culprits is by fasting and doing elimination diets. Fasting can actually help reduce inflammation by calming down your immune system and making your gut barrier stronger. Plus, when you fast, the good bacteria in your gut, like Lachnospiraceae, get a boost. These helpful bacteria produce butyrate, which has anti-inflammatory properties. So, fasting not only helps pinpoint problem foods but also promotes a healthier gut!



When the movement of food through your digestive system slows down because your Migrating Motor Complex (MMC) isn’t working as well, it can lead to constipation. This happens because your body reabsorbs too much fluid from the food. To help with this, you can eat more fiber from plants and take in more magnesium. These steps can both prevent and treat constipation. However, it’s interesting to note that some studies suggest that certain fasting methods, like alternate day fasting, might actually cause constipation for some people.

The best foods to avoid constipation during Inter Fasting

Here i listed Healthy Foods to Eat During Intermittent Fasting to Avoid Constipation

Fiber-Rich Foods

To keep things moving smoothly during intermittent fasting, fiber-rich foods are your best friend. Think fruits, veggies, whole grains, beans, and legumes. These foods help promote regular bowel movements. Some great options include berries, leafy greens, oats, quinoa, lentils, and chia seeds.

Hydrating Foods

Staying hydrated is crucial, especially during fasting periods. Foods with high water content can help keep you hydrated and prevent constipation. Watermelon, cucumber, and tomatoes are excellent choices to include in your meals.

Magnesium-Rich Foods

Magnesium is another key player in preventing constipation. It helps draw water into the intestines and relaxes the bowels. You can get your magnesium fix from spinach, pumpkin seeds, almonds, and avocados.

Probiotic-Rich Foods

Supporting your gut health with probiotic-rich foods is also a good idea. Fermented foods like yogurt, kefir, sauerkraut, and kimchi can help maintain regularity and promote a healthy digestive system.

However, it’s worth noting that certain fasting methods, like alternate day fasting, might actually cause constipation in some people. If you’re considering fasting, especially for IBS-related issues, it’s a good idea to consult a healthcare professional first.

How fiber helpful in intermediate fasting

Here i listed how fiber can be helpful during intermittent fasting:

  • Promotes Regularity and Prevents Constipation
  • Enhances Satiety and Reduces Hunger
  • Supports Gut Health
  • Regulates Blood Sugar Levels
  • May Enhance Weight Loss

Promotes Regularity and Prevents Constipation

Fiber is great for adding bulk to your stool and drawing water into your intestines, which helps keep your bowel movements regular. This is particularly useful during intermittent fasting, when you’re eating less and constipation can become an issue.

Enhances Satiety and Reduces Hunger

Fiber-rich foods like fruits, vegetables, and whole grains can help you feel fuller for longer. This means you’ll experience less hunger and fewer cravings during your fasting periods. The soluble fiber in these foods slows down stomach emptying and delays nutrient absorption, making you feel satisfied for a longer time.

Supports Gut Health

Fiber acts as food for the good bacteria in your gut, helping to maintain a healthy microbiome. This is especially important during intermittent fasting since changes in eating patterns can affect your gut flora.

Regulates Blood Sugar Levels

Fiber slows down the absorption of carbohydrates, which leads to more gradual increases in blood sugar and insulin levels. This helps prevent the spikes and crashes in blood sugar that can happen during the fasting window.

May Enhance Weight Loss

Some studies suggest that a higher fiber intake, combined with intermittent fasting, can lead to greater weight loss and fat loss compared to intermittent fasting alone. 

To get the most benefits from fiber during intermittent fasting, focus on eating a variety of high-fiber foods like fruits, vegetables, whole grains, beans, and nuts during your eating window. Staying hydrated and gradually increasing your fiber intake can also help prevent digestive discomfort.
