How to Prevent Intermittent Fasting Diarrhea After Breaking Your Fast

Intermittent Fasting Diarrhea After Breaking Fast: Causes and Prevention

Fasting Does Not Cause Diarrhea

Fasting does not cause diarrhea in and of itself. Diarrhea is not a side effect of fasting, but it can happen during intermittent fasting. However, it is essential to know that intermittent fasting in itself does not cause diarrhea. It usually happens due to the wrong way of breaking your fast. People who experience diarrhea or watery stools often start to feel symptomatic of low sodium levels. Make sure you drink an extra cup of broth or pickle juice to rehydrate your body and replenish electrolytes.

Diarrhea After Breaking The Fast

Diarrhea is rare when fasting, but some people may experience bowel issues after breaking a fast. This is because your bowels are inactive during the fast. When you break the fast, your bowels react quickly and the food passes through your digestive tract quickly. Sometimes you can experience diarrhea after breaking your fast because you added high-fat meals to your diet plan. Diarrhea happens when your body has difficulty digesting fat, which can lead to loose stools.

Diarrhea During Fasting

Usually, diarrhea occurs after fasting, once the bowels and stomach are in use again. It can also happen while fasting, however, if you have too much caffeine, zero-calorie sweeteners, or take electrolytes on an empty stomach. It’s typically not dangerous as long as you don’t become dehydrated. Nevertheless, it’s likely to happen if you break your fast with the wrong foods or take too many electrolytes. The good news is—you can manage and prevent diarrhea by controlling your diet and understanding how your body reacts to fasting.

Managing and Preventing Diarrhea

No fasting method leads to diarrhea; instead, it usually results from breaking a fast inappropriately. A fasting window slows down your digestive system, so your body can absorb nutrients more efficiently. The key is to break your fast with the right foods to avoid digestive issues. Here’s how to do it:

  • Start with a light snack like fruit, yogurt, or a smoothie.
  • Gradually add more substantial foods like soups, salads, and cooked vegetables.
  • Avoid processed foods, dairy, and high-fat meals.
  • Add extra electrolytes to your diet to replenish lost sodium.
  • Drink plenty of water and herbal teas.

Eating the right foods after fasting will help your body transition more smoothly and reduce the chances of getting diarrhea. Keep in mind that intermittent fasting is a healthy habit if done correctly. Make sure to listen to your body and adjust your fasting window if necessary. With the right diet and lifestyle, you can reap the benefits of fasting without experiencing any digestive issues.


Intermittent fasting diarrhea after breaking fast can be avoided by following a few simple rules. Fasting does not cause diarrhea in and of itself, but it’s essential to break the fast with the right foods in order to prevent digestive issues. Start with light snacks, gradually add more substantial foods, avoid processed foods and dairy, and add extra electrolytes to your diet. With the right diet and lifestyle, you can reap the benefits of fasting without experiencing any digestive issues.
