Intermittent Fasting Diarrhea After First Meal: What Causes It & How to Avoid It
Fasting does not cause diarrhea in and of itself, nor is diarrhea a side effect of fasting. However, diarrhea or nausea during intermittent fasting is not uncommon, and can be an unpleasant surprise for those new to the practice. In this article, we’ll look at why this happens, what to do about it, and how to avoid it in the future.
What Causes Intermittent Fasting Diarrhea?
One of the most common reasons for a person to experience diarrhea after fasting is choosing the wrong foods to break the fast. When you are on a fasting diet, it is important to choose foods that your body can digest easily. If you come out of your fast and binge eat junk food or foods you can’t digest easily, you can upset your stomach, causing diarrhea. In most cases, diarrhea while fasting occurs because of incorrect or unhealthy food choices.
On the most basic level, eating too quickly or too much may upset your stomach and cause diarrhea. In addition, eating sugary or high-fat foods can also cause an upset stomach and diarrhea after a fast. It is important to slowly reintroduce solid foods back into your diet after fasting, as your body may not be accustomed to the extra calories.
Why Does Intermittent Fasting Cause Diarrhea?
Diarrhea happens when the food you eat passes through your gastrointestinal, or GI tract too quickly. This can be caused by a number of factors, including eating too quickly, eating a lot of sugary or high-fat foods, or eating foods that your body cannot easily digest. This unpleasant side effect can be extremely problematic and is one of the most common side effects experienced by people who are new to fasting, especially if they are not familiar with the correct foods to break their fast.
How Can You Avoid Diarrhea After Intermittent Fasting?
The best way to avoid diarrhea after intermittent fasting is to choose the right foods to break your fast. Start by slowly introducing solid foods back into your diet – this will give your body time to adjust to the extra calories. Opt for high-fiber, nutrient-dense foods like fruits and vegetables, whole grains, lean proteins, and healthy fats. Avoid processed and sugary foods, as well as high-fat foods like fried foods, as these can be particularly difficult for your body to digest. Lastly, be sure to drink plenty of fluids before, during, and after your fast to help keep your digestive system in good working order.
Intermittent fasting diarrhea is a common side effect for those new to the practice, but it is not an inevitable one. By choosing the right foods to break your fast and drinking plenty of fluids, you can help prevent this unpleasant side effect. So, the next time you come out of a fast, take your time, choose your foods wisely, and enjoy the benefits of intermittent fasting without the worry of diarrhea.
