PCOS & Weight: Less Lies; More Truth

Your weight DID NOT cause your PCOS or Polycystic Ovarian Syndrome. It's sad that I still have to say this after all the new science we have about PCOS and weight. But the false belief that being overweight or having obesity causes PCOS continues. For example, I was outraged when a well know functional medicine doctor with over 2 million followers shared that PCOS people needed to simply "change their diet." But I digress.

As an integrative obesity specialist and women's metabolic health expert, I became passionate about PCOS because I met many women at my primary care practice in their 30s-50s with undiagnosed PCOS. Sadly by the time we met, they had the health consequences of untreated PCOS: obesity, metabolic syndrome, diabetes, heart disease, and more. I don't want any woman to walk around with undiagnosed PCOS or continue struggling with her weight due to ineffective PCOS treatment.

September is PCOS Awareness Month. To commemorate the month I:

  • Joined Dr. LJ, the Wholistic Endo Expert, on her phenomenal podcast to discuss PCOS, Weight Gain, Obesity, & Chronic Fatigue*

  • Hosted "PCOS & Weight: What's Really Going On?" Overcoming Obesity Club Room* *Links in the resources section

In this blog post, we'll review PCOS diagnosis and Three misconceptions about PCOS and weight.

PCOS Diagnosis

PCOS is the most common hormonal condition in women of ages 30-50 or "childbearing age". Up to 10% of women have PCOS and don't know it. Weight gain that's difficult to control can be one of the most common symptoms of PCOS. But often, doctors and clinicians focus on the weight without digging deeper to find out why they are gaining weight. Weight gain is more than "calories in vs. calories out." The are over 100 triggers for weight gain. Time and time again, I've found when you treat the root cause of weight gain, for example, PCOS, you lose the extra weight the body is holding onto.

This brings me to misconception number one.

Misconception One

❌You have to be overweight to have PCOS.

This is a common misconception and honestly bias that many clinicians have. Here's how to diagnose PCOS:

  • Make sure there are no other causes of your symptoms. PCOS is a "diagnosis of exclusion", which means other disease conditions that look like PCOS must be evaluated before you can diagnose PCOS.

  • The clinical criteria for diagnosing PCOS is having two of these three symptoms:

    • Laboratory or clinical evidence of high androgens (i.e. hirsutism-hair on the face, chest, and back, High testosterone levels, etc )

    • Unpredictable or lack of menstruation ( “Oligomenorrhea or anovulation”)

    • Radiographic evidence of polycystic ovaries (Large follicle >10ml or more than 12 follicles 2-9mm in size)

Rotterdam Criteria, 2003

What’s “missing“ in the criteria? Notice that there is no mention of weight, BMI, or waist circumference in the PCOS diagnostic criteria.

20-40% of women with PCOS will not be overweight by the current standards of diagnosing obesity (BMI >30kg/m2 or Waist Circumference >35inches or 88cm).

However, it is important to note regardless of your weight, you are still at risk of the metabolic conditions associated with PCOS. PCOS causes high androgen levels and insulin resistance, increasing your risk of heart disease and other conditions. Insulin resistance will impact 40% of people with PCOS. Insulin resistance can put you at risk for obesity, metabolic syndrome, type 2 diabetes, and heart disease.

Misconception Two

❌Your weight “caused” you to get PCOS.

While there is an association between the medical condition of obesity and PCOS, obesity does not directly cause PCOS. This is evident since most people with obesity do not have PCOS.

Conversely, the hormonal changes associated with PCOS can cause obesity. A PCOS and insulin resistance diagnosis increases your risk of developing obesity (defined as BMI >30 kg/m2 in the studies that researched PCOS and obesity risk). Unlike previous understandings of body weight and obesity, we now know that Your Healthy Weight is determined by more than the BMI cut-off of >30kg/m2. In Embrace You, we use a more individualized approach to determining Your Healthy Weight beyond the standard BMI tables.

Misconception Three

❌You can’t lose weight if you have PCOS

Trying to lose weight when you have PCOS can be frustrating, especially if you aren’t given the right guidance. The old dieting weight loss model of “calories in” vs “calories out” can harm PCOS warriors. Why? For many reasons:

  • Food quality is more important than calories: Due to insulin resistance, we know that people with PCOS insulin resistance are more sensitive to foods high in sugar and refined carbohydrates. Ironically you may crave these foods because your body isn’t able to use the glucose (or breakdown product of sugar) very well. This leads to a vicious insulin release cycle, worsens insulin resistance, and drives weight gain. That is why optimizing your nutrition in PCOS is so important.

  • Changes in appetite: PCOS affects your hunger hormones. Specifically, Ghrelin, the “hunger hormone” released from gastric (stomach) cells, tells the brain you’re hungry. Normally, ghrelin decreases after eating, but in PCOS patients, ghrelin remains elevated higher than expected. This leads you to feel hungry and unsatisfied with your meals.

  • “Energy In” vs. ``Energy Out”: We know now that body weight regulation or, more specifically, body fat regulation depends much more than calories but actually “energy in” vs. “energy out.” PCOS impacts your energy balance in many ways that can affect your energy beyond your plate or in the gym. The impact of PCOS on your mood, relationships, and other aspects of your life can also impact your weight.

Despite all these factors, if you want to lose weight with PCOS. It’s not impossible to lose weight with PCOS. However, your weight plan has to address all the factors contributing to your energy imbalance and fit into your lifestyle. Traditional dieting forces you to focus on the scale. However, your life is more than the scale, so your weight and wellness plan has to look beyond the scale, calorie counts, and gym workouts you can’t stand. My bestselling book, Embrace You: Your Guide To Transforming Weight Loss Misconceptions Into Lifelong Wellness, equips you with your individualized strategy for your wellness-based weight and wellness journey. It also helps you to identify your team for managing your PCOS weight loss journey.
