Intermittent fasting helps you manage your eating habits in different ways. By restricting your eating windows, your body can tap into its fat resources once it works through the active calorie and sugar stores. It is not a type of eating disorder, and it is not a recommended diet plan for someone who has a history of eating disorders.
Why You May Want to Avoid Intermittent Fasting in Recovery
Depending on the program, intermittent fasting can require you to go long times without food, which may be triggering for those who have a history of eating disorders, including anorexia and bulimia.
Intermittent fasting is highly restrictive. To maximize your weight loss results, you plan out when and what you eat. For those who have issues with eating, this may cause you to fall back into old habits. If you fear you may have an eating disorder, reach out to a doctor. Intermittent fasting is part of your lifestyle, but it’s not the main focus. If you are hyper-focused on your eating habits, it may become an issue.
Intermittent Fasting and Bulimia
In the beginning, you’ll likely be starving after a fast until your body gets used to the new schedule. Because of that, you’ll be tempted to binge eat all you can once your window is open. Afterward, you may not feel so great. You may feel bloated or unwell. Perhaps you feel guilty.
The next step for those with bulimia would be to purge their food. If they get rid of it, it cannot be digested, and therefore the calories don’t count. This line of thinking is untrue and extremely unhealthy. The urge to binge and purge is classic behavior for bulimia, so if you notice any of these signs, seek medical help before it becomes a problem. Intermittent fasting is a weight-loss tool, not an enabler for unhealthy behaviors.
Intermittent Fasting and Anorexia
Certain intermittent fasting programs ask you to restrict your calories to create a calorie deficit. After all, you want to burn more calories than you eat in a day. However, if you start to hyperfocus on restricting your calories, you may have problems. Intermittent fasting helps you burn fat, but it should never be used to limit your caloric intake in unhealthy ways.
You should be eating a minimum of 500 to 600 calories during your eating windows. If you are eating less, your body may not properly function, and you may begin to feel faint. Do not use intermittent fasting to justify an eating disorder. Its roots go back thousands of years, connecting it with spirituality. It should not be used negatively.
What If My Intermittent Fasting Has Become a Problem?
Recognizing you may have an issue is an important first step. Please see a professional if you suspect you may have developed or relapsed into an eating disorder following intermittent fasting. They can help you manage your eating in healthy, less triggering ways. Intermittent fasting is not effective for everyone.
