If you have Polyendocrine Metabolic Ovarian Syndrome (PMOS)/ polycystic ovary syndrome (PCOS), chances are you've been told to "just lose weight" at some point.
Maybe you've tried cutting carbs, eating less, or exercising more, only to lose weight and regain it all back, again and again. Perhaps you’re also tired of hearing about weight loss as the answer to every PMOS (PCOS) symptom, but still find yourself wanting to do so.
Here's something we want you to know: It's okay to pursue weight loss (we live in a weight-centric world), and it's also okay to prioritize your health without making weight loss the goal.
PMOS (PCOS) is a complex hormonal and metabolic condition, and managing it involves much more than the number on the scale. Let's explore what the research tells us about PMOS (PCOS) and weight gain, how weight stigma can affect your health, and what you can focus on to feel better in your body.
Why Does PMOS(PCOS) Make Weight Loss So Difficult?
PMOS (PCOS) is a hormonal condition that can affect menstrual cycles, ovulation, insulin sensitivity, and metabolic health. While not everyone with PMOS(PCOS) experiences weight gain, research suggests that people with PMOS (PCOS) tend to have a higher body mass index (BMI) compared to those without the condition.
But why does this happen?
According to the 2023 International Evidence-Based Guidelines for PCOS, researchers have explored two broad categories of factors that may influence weight: extrinsic factors, such as eating and physical activity habits, and intrinsic factors, such as metabolism and appetite regulation.
1. Is Weight Gain in PMOS (PCOS) Caused by Eating More or Exercising Less?
One of the most common misconceptions about PMOS(PCOS) is that weight gain happens because someone is eating too much, consuming too many carbohydrates, or not exercising enough.
But the research tells a more complicated story.
When researchers compared dietary intake and physical activity habits between people with and without PMOS (PCOS), they did not find consistent evidence of significant differences.
In other words, people with PMOS (PCOS)aren't necessarily eating more or moving less than people without PMOS (PCOS).
This challenges the idea of “just eat less and move more” narrative that gets slapped on many patients’ “treatment plans.” It simply is not that simple. In fact, it’s quite stigmatizing. For both those with relatively higher or relatively lower weights, this can delay diagnosis and effective treatment, and cause tons of harm.
Also, eating and movement habits don't happen in isolation. What’s missing is data on how social determinants of health impacts people with PMOS(PCOS), although studies like this that assess food security status in this population are starting to pop up. Which is great! But we need more.
We know that access to healthcare, food availability, financial resources, social support, safety and our physical environments all influence our health and ability to engage in health-promoting behaviours.
2. Does PMOS(PCOS) Affect Your Metabolism?
Another possible explanation involves differences in how the body uses energy.
Your resting energy expenditure refers to the energy your body uses to support essential functions, such as breathing, circulation, and maintaining body temperature, even when you're resting.
Some research suggests that people with PMOS(PCOS) may have lower resting energy expenditure, meaning their bodies may use less energy at rest. However, findings remain mixed, and researchers have not established exactly how much this contributes to weight differences.
Appetite-regulating hormones, hunger and fullness signals, and the energy used to digest food have also been investigated, but the evidence remains inconclusive.
The takeaway?
We don't fully understand why weight gain may be more common with PMOS(PCOS), and it cannot simply be attributed to a lack of effort and prescribing people to “eat less calories” as a “treatment.”
And even if your body uses less energy at rest, that doesn't mean you should skip meals, drastically reduce your food intake or ignore your hunger. Engaging in these behaviours, without the support of a qualified Registered Dietitian in this area, can wreak havoc on health, we see it time and time again. Malnutrition, muscle wasting, increased risk of bone fractures, cognitive decline, disordered eating and so much more.
Your body still needs adequate nutrition to support your hormones, energy levels and overall health.
How Weight Stigma Can Affect PMOS(PCOS) Care
If you've ever brought up concerns about irregular periods, fatigue, or other PMOS(PCOS) symptoms, only to be told that it’s a “weight issue”, you may have experienced weight stigma.
Weight stigma refers to negative attitudes, assumptions, or discrimination directed toward someone because of their body weight.
In healthcare, this can look like:
Having symptoms dismissed or automatically attributed to weight. (“I haven’t had my period in a year and I keep growing more facial hair.” “You should lose weight.”)
Receiving weight loss advice without further investigation or individualized support.
Feeling judged or blamed for having difficulty managing PMOS(PCOS) symptoms.
Experiencing delayed diagnosis because your body doesn't fit the stereotypical appearance of someone with PMOS( PCOS). (“You’re too ‘lean’ to have PMOS/PCOS”)
Weight stigma can affect people across the weight spectrum.
For example, someone in a smaller body may experience delayed PMOS( PCOS) diagnosis because their healthcare provider assumes they cannot have the condition.
For others, repeated pressure to lose weight may contribute to restrictive eating and malnutrition, causing health decline, weight cycling, anxiety or a strained relationship with food.
Research has also linked weight stigma with poorer psychological and physical health outcomes.
This is why a weight-neutral, individualized approach to PMOS(PCOS) care matters. Your symptoms deserve to be taken seriously, regardless of your body size.
What If You Still Want to Lose Weight With PMOS(PCOS)?
Let's acknowledge something that often gets overlooked in conversations about weight-neutral healthcare.
You can recognize that weight stigma exists, understand that weight doesn't define your health or worth, and still want to lose weight.Those feelings can coexist.
We live in a society that places considerable value on body size. At Nest & Nurture Health, our goal isn't to shame you for wanting weight loss or pressure you into loving every aspect of your body. Instead, we encourage you to consider a broader question:
If your weight changed, what do you hope would be different about your life?
What do you believe losing weight would give you that you don't have right now?
Are you hoping to feel healthier, more confident, more comfortable, more accepted, or something else?
Because you deserve to feel good in your life right now, not just in some future version of your body.
And you can work towards your health goals without making weight loss the measure of your success.
5 Ways to Support Your PMOS(PCOS) Health Beyond Weight Loss
Instead of focusing exclusively on cutting calories, consider the factors you can meaningfully influence through nutrition and lifestyle habits.
Here are five areas to start with.
1. Eat Regularly Instead of Skipping Meals
Do you find yourself rushing out the door without breakfast, grabbing something small for lunch, and feeling extremely hungry by dinner?
When you're busy, it's easy to unintentionally undereat throughout the day. But going long periods without enough food may leave you feeling overly hungry later, making it harder to recognize your hunger and fullness cues.
Rather than trying to eat less, start by creating a more consistent eating routine.
This might mean making time for breakfast, planning a satisfying lunch, or keeping convenient snacks available when your schedule gets busy.
The goal isn't to follow a rigid eating schedule. It's to provide your body with consistent nourishment in a way that works for your lifestyle.
2. Build Balanced Meals That Support Insulin Sensitivity
Insulin resistance is common in PMOS(PCOS) and can contribute to metabolic concerns.
Insulin resistance happens when your body's cells become less responsive to insulin, a hormone that helps move glucose (sugar) from your bloodstream into your cells for energy.
Rather than eliminating carbohydrates, focus on building balanced, satisfying meals that support blood sugar regulation.
This may include combining carbohydrate-containing foods with sources of protein, fibre, and healthy fats.
For example, you might pair rice with tofu and vegetables, enjoy oatmeal with Greek yogurt and berries, or add beans and avocado to a tortilla.
You don't need to eliminate your favourite foods or follow a perfect meal plan to support your metabolic health.
3. Support Your Metabolic Health Through Movement and Other Daily Habits
Nutrition is only one part of PMOS(PCOS) management.
Movement, sleep, and other daily habits can also play important roles in supporting insulin sensitivity and metabolic health.
Instead of approaching exercise as a way to burn calories, consider movement that feels enjoyable, accessible and sustainable.
Strength-based activities can also help build and maintain muscle mass, which contributes to metabolic health.
Remember, you don't need to change everything at once. Small, consistent habits are often more manageable than an all-or-nothing approach.
4. Reconnect With Your Hunger, Fullness, and Food Experiences
If you've spent years following diets or food rules, recognizing your body's hunger and fullness cues may not feel straightforward.
You might notice that you eat past fullness after a day of restriction, experience frequent food cravings, or feel guilty after eating certain foods.
Rather than immediately trying to control these experiences, get curious about what's contributing to them.
Are you eating enough during the day? Are your meals satisfying? Could stress, medications, or your daily routine be influencing your appetite?
Understanding these patterns can help you build a more supportive relationship with food.
And if eating feels particularly stressful or overwhelming, you don't have to navigate it alone.
5. Measure Progress Beyond the Scale
When weight is your only measure of progress, it's easy to overlook meaningful changes happening in other areas of your health.
Consider paying attention to improvements such as:
Having more consistent energy throughout the day.
Feeling less bloated or experiencing more comfortable digestion.
Noticing improvements in blood sugar or cholesterol levels.
Feeling more confident planning and preparing meals.
Enjoying food with less guilt, anxiety, or stress.
Developing eating and movement habits that feel realistic to maintain.
These improvements matter, whether or not your weight changes.
Your progress isn't defined by a number. It's also reflected in how you feel, how you care for yourself, and the habits you're able to sustain.
Can You Manage PMOS(PCOS) Without Losing Weight?
Yes. You can take meaningful steps to manage PMOS(PCOS) symptoms and support your metabolic health without making weight loss your primary goal.
Nutrition strategies, movement, sleep, and individualized healthcare can support areas such as insulin sensitivity, menstrual health, digestion, and overall well-being.
The most helpful approach will depend on your symptoms, medical history, preferences, and personal goals.
It's also worth remembering that weight changes are not always predictable. You may notice improvements in your energy, relationship with food, or blood work without seeing a significant change on the scale.
That doesn't mean your efforts aren't working.
A More Weight Neutral Approach to PMOS(PCOS) Nutrition
If there's one thing we hope you take away, it's this: You don't need to spend your life fighting your body to take care of your health.
Wanting to lose weight doesn't make you wrong, and choosing not to pursue weight loss doesn't mean you're giving up on your health.
You deserve nutrition care that looks beyond your weight, considers your lived experiences, and helps you build habits that support your well-being in the long term.
At Nest & Nurture Health, we take an individualized, weight-neutral approach to PMOS( PCOS) nutrition. Rather than focusing on restrictive diets or rigid food rules, we help you understand your body, nourish yourself consistently, and develop practical strategies that fit into your everyday life.
