What is intermittent fasting?
Intermittent fasting is to follow a schedule that cycle between fasting and non-fasting, for example, not eating for a period of time each day or week. Some popular methods are alternate-day fasting (eat normally one day and completely fast or reduce calorie intake the next day) and daily time-restricted fasting (eat normally but only within a several-hour-long window each day).
What is the side effect of intermittent fasting?
Intermittent fasting can have various side effects, depending on the individual and the method of fasting. Some common side effects include hunger, irritability, and difficulty concentrating during the fasting period. Other side effects can include headaches, dizziness, and nausea. It is also possible to experience changes in bowel movements, such as constipation or diarrhea.

In some cases, intermittent fasting can also lead to overeating during the non-fasting period, which can result in weight gain instead of weight loss. Additionally, people who are at risk of or have a history of eating disorders should avoid intermittent fasting, as it may trigger unhealthy behaviors.

It is important to note that intermittent fasting may not be suitable for everyone, and people with certain medical conditions or who are taking certain medications should consult with a healthcare provider before attempting intermittent fasting. It is also crucial to maintain a balanced diet during the non-fasting period to ensure that the body receives the necessary nutrients.
