Disordered Eating with PCOS – Are you at risk?

If you have been following PCOS Diet Support for a while you will know how firmly I believe in a PCOS diet to help manage the symptoms of PCOS. But can this ever lead to disordered eating with PCOS?

This is something that I have been thinking about for a little while and I definitely think that we are at risk of disordered eating so it is something that we need to be aware of.

Research suggests that women with PCOS are more prone to develop an eating disorder than women without PCOS. Also, up to 39% of women with PCOS have been shown to display binge eating disorders. Thus, disordered eating is something that women with PCOS need to be aware of as they are more likely to develop irregular patterns of eating behaviours.

Let’s start by looking at what disordered eating actually is.

What Is Disordered Eating?

According to The Academy of Nutrition and Dietetics, disordered eating is a term used to describe a range of irregular eating behaviours. Irregular eating behaviours don’t necessarily mean an eating disorder, though.

So, just to be clear, I am not suggesting that women with Polycystic Ovary Syndrome are prone to eating disorders, but I do think that we are at risk of developing irregular eating behaviours.

Some of the symptoms of disordered eating include:

  • Frequent dieting, anxiety associated with specific foods or meal skipping
  • Chronic weight fluctuations
  • Rigid rituals and routines surrounding food and exercise
  • Feelings of guilt and shame associated with eating
  • Preoccupation with food, weight and body image that negatively impacts the quality of life
  • A feeling of loss of control around food, including compulsive eating habits
  • Using exercise, food restriction, fasting or purging to “make up for bad foods” consumed

Have a look at that list. Are there any that stand out for you? Can you relate to any of this?

Let’s have a look at some of the reasons we may struggle with some of these symptoms.


Why we Need to Consider Disordered Eating with PCOS

Using a PCOS diet to manage PCOS symptoms

I have long suggested that diet is one of the most powerful ways that we can manage our PCOS. And while I still believe this is true, it can result in some anxiety if we stray too far from the recommended guidelines.

Focus on Losing Weight or Weight Gain

A lot of women with PCOS struggle with losing weight or gaining weight. This can give us a negative body image, but it also puts us at increased risk of some of those disordered eating behaviours, like frequent dieting, overtraining and feelings of guilt associated with eating.

Cravings are Real

cravings-with-pcosIf you have PCOS, then I am sure that you are all too familiar with the cravings that so often accompany PCOS. The struggle is real!

And you are absolutely not alone!

In fact, Jeanes et al (2017) suggest that up to 39% of women with PCOS show binge eating behaviours. This does not necessarily mean that all 39% of these women had a binge eating disorder but the study did suggest that women with PCOS are prone to binge eating and should be screened for a binge eating disorder.

We’re more Prone to Eating Disorders

Interestingly, a meta-analysis of 8 studies, including 470 women with PCOS showed that women with PCOS compared with women without PCOS are more prone to the development of an eating disorder (Lee et al., 2019).

So, what does this all mean for you? Are you destined to struggle with disordered eating behaviours for the rest of your life? Absolutely not! There are some things that you can do.

How to Improve or Avoid Disordered Eating with PCOS

Get help if you need it

If you have been reading this and alarm bells are ringing, you may want to think about seeking professional help. If food or even body image has become something of an obsession or it dominates your thought life, perhaps it is time to see someone who specializes in treating eating disorders.

Yes, PCOS can be managed by the foods that we eat. But, obsessing or thinking about food or your PCOS all of the time is not helpful longer-term and may seriously impact on your quality of life.

Follow the 80/20 Principle

 80:20-principleThere is no doubt in my mind that following a good PCOS diet is helpful for PCOS. But striving for perfection is exhausting and unrealistic. There may well be times that you fall off the bandwagon, give in to cravings, have whatever the heck you want.

And that is OKAY!

If you were to follow the guidelines for a PCOS diet 80% of the time, it gives you leeway to “let your hair down” and not give in to the guilt and shame associated with it. Does that mean that we can all go on a binge?

No. Binge eating is defined as “the consumption of large quantities of food in a short period of time, typically as part of an eating disorder.

Giving yourself the freedom to stray from your normal eating patterns does not mean that you have to completely binge. Eating less healthy food choices in moderation is very different from displaying binge eating behaviours that are unhealthy in the long term.

Avoid Fad or Crash Diets

Dr Gottlieb is a clinical psychologist specializing in the treatment of eating disorders. She recommends that we avoid fad or crash diets. They tend to be too restrictive and can be hard to sustain. So, although we may be able to stick to them over the short term, longer-term they are likely to result in binge eating behaviours.

Change your Focus

disordered-eating-focusSo many of us struggle with weight and that becomes our focus, leading us to weigh ourselves daily or multiple times each day. Instead of focusing solely on weight, it would be more helpful to change the narrative, focusing on being healthy instead of just focusing on weight loss.

For example, instead of thinking “I’m going to restrict my calories to x amount to help me lose weight.” Change the narrative to “I’m going to focus on eating a wide variety of whole foods and less processed foods to better manage my hormones and be healthy with my PCOS.”

The focus is on longer-term health, not just weight loss.

In summary, in our effort to be as healthy as we can with PCOS, we need to be aware of the risk of developing disordered eating patterns and try to steer clear of this. If you do feel you have developed unhealthy eating patterns and need extra help, I really want to encourage you to seek professional help.

If you have any experience of disordered eating with PCOS, I would love to hear from you and learn from your experience of this all-important topic!

  1. I know this is a long time after this was originally posted but I really hope for a response. I was diagnosed with PCOS when I was 16 in 2012 and have been struggling with disordered eating since 2017. I believe that my PCOS has a very big role to play within that. Information about the correlation between the two has been very hard to find.

    I think I’ve always had issues with irregular eating habits, as a child/teenager it was more along the lines of binging. When I was diagnosed I jumped headfirst into a diet change, I had finally been given the tools to be able to shift the weight and have a period. This website was what prompted it actually, I even had a membership :). All of this information particularly about what we should and should not eat and the glycemic scale became somewhat obsessive, especially since wherever I went there weren’t usually “PCOS friendly” options around. Eventually because life became very chaotic, I completely stopped looking after myself and being careful with what I was eating.

    This is where it gets strange. After 10 years of hating my body because it was overweight, I finally came to full acceptance, even self love. After this point with no active thought about my PCOS or body image being involved, my appetite began to drop off. Over 6 months or more I slowly began eating less and less, eventuating to eating every 3 to 5 days, breaking the fast with one biscuit. I went on this way for 3 months, only sustaining my body with tea and coffee. I will reiterate that these behaviours were not a conscious choice. I dropped 15kgs in a month and was not aware that I had lost any weight until a friend pointed it out. Then I had my wisdom teeth removed and dropped another 10kgs that week. Following this was when I began to get sick. Food became completely foreign and I couldn’t stomach anything without anti-nausea medication. I was too weak to even stand two minutes without beginning to black out.

    I had a lot of support at the time from concerned friends and family because it was very clear to see that I was unwell (BMI 35 down to 20.2 in 4 months) and with time that support I was able to recover.
    Unfortunately because I lost weight so quickly my body didn’t come out of that weight loss looking too good. I’m 23 with no kids and I look like I’ve had several. So now I have even worse body image than I ever did while I was bigger. I have also developed a fear of gaining weight. This led to the obsession around PCOS and food coming back.
    Over the last 12 months or so I have been bouncing back and forth between binging and restricting. Over the last few weeks its leaning back toward a loss of interest (not conscious) in food like before and I’m not eating very much anymore. I don’t have a lot of body fat to survive on like last time.
    I’m seeking help because I have a very unhealthy mindset around PCOS and food and my issues around food seem to continually evolve but don’t get resolution. I just really don’t know what to do and I’m so overwhelmed with my life overall. I need help. Please.
