Losing Weight with PCOS & Why It’s Hard (Dietitian Approved Recommendations + Tips)
How PCOS Affects Your Body's Ability to Lose Weight
If you’ve been struggling to lose weight with PCOS, it’s not just in your head - your body’s biology is working against you. PCOS disrupts key hormonal and metabolic processes, making traditional weight loss methods less effective. Let’s break it down by looking at the roles of hormonal imbalances, insulin resistance, and inflammation in weight gain.
Hormonal Imbalances and Weight Gain
PCOS throws your hormones out of balance, and this can have a direct impact on your weight. Elevated androgens (sometimes called "male hormones") and high insulin levels can increase your appetite, spark cravings for calorie-dense foods, and promote fat storage around your abdomen. Essentially, your body’s hormonal signals can drive these behaviors.
High insulin levels, in particular, stimulate the production of androgens, which are linked to weight gain, acne, and irregular menstrual cycles. At the same time, disrupted ovarian function can lead to higher estrogen levels, further fueling appetite and fat storage. Some people with PCOS also experience low thyroid function, which can slow metabolism and contribute to weight gain.
Dr. Yolanda Thigpen, an Ob/Gyn, explains it this way:
"Experts think a combination of genetic predisposition and environmental factors, including diet, exercise and lifestyle, contribute to the PCOS symptoms".
The pattern of weight gain with PCOS is often concentrated in the abdominal area, which is particularly concerning because it’s associated with higher health risks.
Insulin Resistance and Metabolism Problems
Insulin resistance is a major player in PCOS-related weight issues, affecting 50% to 75% of individuals with the condition. When your cells don’t respond properly to insulin, your pancreas ramps up insulin production. This excess insulin not only promotes fat storage - especially around the midsection - but also makes it harder for your body to burn calories efficiently.
Here’s a striking statistic: 70% to 80% of women with a BMI over 30 and 20% to 25% of lean women (BMI under 25) with PCOS show signs of insulin resistance. High insulin levels can also increase hunger, making it even harder to maintain a calorie deficit for weight loss. Beyond fat storage, insulin resistance disrupts how your body handles energy, further complicating weight management.
Chronic Inflammation and Appetite Control
PCOS is often accompanied by low-grade inflammation, which can worsen insulin resistance and interfere with appetite regulation. Markers like CRP and IL-6 are elevated in people with PCOS, and this systemic inflammation can even affect the hypothalamus - the part of the brain that controls hunger and metabolism.
The link between inflammation and weight is especially evident when you consider that about 30% of women with PCOS have visceral fat, the type of fat stored around internal organs. This fat is metabolically active, releasing inflammatory compounds that worsen insulin resistance and make weight loss harder. Chronic inflammation can also disrupt ovarian function, leading to ovulatory issues. Additionally, excess fat can convert androgens into estrogen, further throwing off the hormonal balance that regulates your reproductive system.
Inflammation doesn’t just affect your metabolism - it can also impact your mental health. It’s been linked to higher rates of depression in people with PCOS, which can make sticking to healthy habits even more challenging. However, even small amounts of weight loss can help reduce inflammation and improve PCOS symptoms, showing how interconnected these factors are.
Diet Changes That Help with PCOS Weight Loss
For those managing PCOS, addressing insulin resistance and reducing inflammation is crucial. These dietary changes can complement hormonal and metabolic strategies, making weight management more achievable.
Balanced Macronutrient Ratios
Balancing macronutrients is key to stabilizing blood sugar levels, especially for those dealing with insulin resistance. Incorporating protein, healthy fats, and fiber into every meal can help prevent the blood sugar spikes that worsen insulin resistance.
Prioritize protein at every meal and snack. Lean meats, fish, eggs, legumes, and tofu are excellent options. Protein slows carbohydrate absorption and helps you stay full longer, which is particularly important for women with PCOS who are often insulin resistant.
Opt for the right carbohydrates. Instead of cutting out carbs entirely, focus on low-glycemic options like whole grains and non-starchy vegetables. Amanda Stathos, M.S., R.D., L.D.N., advises:
"Eliminating carbs is not something I recommend. However, choosing more low-glycemic carbohydrates (those that do not cause a surge in blood sugar) such as fiber-rich whole grains and non-starchy vegetables can be helpful. The goal is to keep blood sugar stable and avoid big dips and spikes".
Incorporate healthy fats. Foods like avocados, nuts, seeds, olive oil, and fatty fish can help regulate blood sugar and improve insulin sensitivity. Pairing carbs with protein and healthy fats further minimizes blood sugar fluctuations throughout the day.
| Food Group | Best Choices for PCOS | Foods to Limit |
|---|---|---|
| Carbohydrates | Brown rice, quinoa, oats, non-starchy vegetables, berries, apples | White bread, white rice, pastries, sugary desserts |
| Proteins | Fish, chicken, legumes, tofu, eggs | Processed meats, excessive red meat |
| Fats | Olive oil, avocado, nuts, seeds, fatty fish | Fried foods, processed foods high in saturated fat |
| Beverages | Water, unsweetened tea | Soda, fruit juice, sugary drinks |
Anti-Inflammatory Foods to Include
PCOS is often linked to higher levels of inflammation, as indicated by elevated CRP levels. Including anti-inflammatory foods can help alleviate symptoms and promote overall health.
Eat omega-3-rich foods daily. Fatty fish like salmon and sardines, along with avocados, nuts, and olive oil, can reduce inflammation and support hormonal balance.
Add colorful fruits and vegetables. Berries, leafy greens like kale and spinach, and tomatoes are packed with antioxidants that help combat inflammation. The Mediterranean diet, which emphasizes these foods, has shown promise in reducing inflammation linked to PCOS.
Amanda Stathos, a Clinical Dietitian at Johns Hopkins' Sibley Memorial Hospital, highlights:
"Research shows that people with PCOS show evidence of all-over inflammation, which is associated with heart disease and other illness. The Mediterranean diet eliminates saturated fats, processed meats and refined sugar, which makes it a powerful tool to address inflammation".
Spice it up. Turmeric and cinnamon are not only flavorful but also have properties that help reduce inflammation and support blood sugar control. Try adding turmeric to your smoothies or sprinkling cinnamon on oatmeal or yogurt.
Shift your focus to fish and vegetables. Increasing these while cutting back on red meat, refined grains, and sugary foods can help lower inflammation and improve PCOS symptoms.
Meal Timing and Portion Control
Hormonal imbalances and insulin resistance can disrupt hunger cues in women with PCOS, making meal timing and portion control essential. Consistent eating patterns help regulate hunger, prevent overeating, and maintain steady energy levels.
Stick to a regular eating schedule. Aim for three meals and one snack spaced 4–6 hours apart. This helps lower insulin levels between meals, which is especially beneficial for those with PCOS.
Use portion control techniques. The MyPlate method works well: fill half your plate with non-starchy vegetables, one-quarter with lean protein, and one-quarter with starchy carbs or grains. Tools like measuring cups or using your hand as a guide can help you keep portions in check.
Plan your largest meals wisely. Dr. Shruthi Mahalingaiah, MD, MS, suggests:
"It helps to plan your meals at times when they can actually fuel your activity".
Try eating your biggest meals before your most active periods and avoid eating within three hours of bedtime to support digestion and better sleep.
Practice mindful eating. Take your time during meals, avoid distractions, and stop eating when you're about 80% full. This can help you reconnect with your hunger signals, which are often disrupted by PCOS-related hormonal changes. For those aiming to lose weight, limiting carbohydrates to 3–4 servings per day while maintaining balance can be effective.
Even small changes can make a difference. Research shows that losing just 5% to 10% of body weight can significantly improve PCOS symptoms. The key is consistency and sustainable habits rather than extreme diets or restrictions.

Exercise Plans for PCOS Weight Loss
Exercise plays a key role in managing PCOS symptoms and promoting healthy weight loss. Women with PCOS often face increased risks of obesity and diabetes, but regular physical activity can help balance hormones and reduce testosterone levels. When paired with a proper diet and medical treatments, exercise addresses the metabolic challenges at the heart of PCOS.
Research suggests that vigorous aerobic exercise is particularly effective for lowering BMI and improving insulin resistance compared to moderate activity. However, the most important factor is consistency. Even small amounts of exercise - like 30 minutes a day, three times a week, or around three hours weekly - can significantly improve both metabolic and reproductive symptoms tied to PCOS. These exercise routines, combined with dietary adjustments, create a well-rounded approach to PCOS management.
High-Intensity Interval Training (HIIT) for Insulin Sensitivity
HIIT, which alternates short bursts of intense activity with recovery periods, offers unique benefits for women with PCOS. It not only improves body composition and insulin resistance but also boosts calorie burn long after the workout ends. This "afterburn effect" is especially helpful for women who often experience slower metabolisms.
Begin with 20-second bursts of intense effort followed by 40 seconds of rest for 10–15 minutes. Gradually increase the intensity and duration. Activities like sprinting, burpees, jumping jacks, or cycling at full effort work well for HIIT.
Focus on HIIT over steady-state cardio for optimal results.
A study by Almenning et al. revealed that HIIT improved insulin resistance in women with PCOS, even without weight loss, and significantly enhanced body composition when combined with high-intensity strength training. This highlights how effective HIIT can be in improving your body's ability to use insulin efficiently, regardless of immediate weight changes.
Plan your week wisely. Include 2-3 HIIT sessions weekly, ensuring at least one rest day between workouts. Personal trainer Olivia Tyler recommends combining daily activity with resistance training for better glycemic control:
"Daily activity is important in glycaemic control and vigorous aerobic exercise can help to also increase insulin sensitivity. Adding in some resistance training per week will also help as this increases metabolic activity which also improves insulin sensitivity".
While HIIT burns calories post-workout, strength training builds the lean muscle needed to support a healthy metabolism.
Strength Training for Muscle Growth and Metabolism
Strength training offers multiple advantages for women with PCOS by tackling symptoms like insulin resistance and elevated male hormones. It also helps prevent the weight loss plateaus often associated with PCOS.
Focus on compound movements like squats, deadlifts, push-ups, and rows to build muscle and boost your metabolism. These exercises promote the growth of muscle cells, which aids in maintaining stable blood sugar levels throughout the day.
Go for lighter weights with higher repetitions. This approach builds lean muscle without overloading your body, making it ideal for managing PCOS.
A 2016 study of 43 women with PCOS found that 16 weeks of strength training significantly reduced testosterone levels, helping to alleviate symptoms like facial hair, belly fat, hair loss, and acne.
Stick to two strength-training sessions per week. Leave at least one rest day between these workouts to allow your muscles to recover. Since muscle tissue burns more calories at rest than fat, building muscle helps maintain a higher metabolism even when you're not active.
| Benefit of Strength Training | Description |
|---|---|
| Improves Insulin Sensitivity | Builds muscle that helps regulate blood sugar and reduces the pancreas's insulin workload. |
| Lowers Male Hormones | Reduces androgen levels, alleviating symptoms like excess hair growth, acne, and abdominal fat. |
| Prevents Weight Loss Plateaus | Maintains metabolism and muscle mass during dieting, keeping calorie burn steady. |
Low-Impact Exercises for Beginners
For those new to exercise or dealing with joint pain, low-impact activities are a great way to start. These gentle movements still provide meaningful benefits for PCOS management without putting too much strain on your body.
Walking is a great option. Amy Plano, a registered dietitian and diabetes educator, emphasizes its simplicity:
"Walking is one of the most underrated aerobic exercises. It can be done anywhere, anytime and requires no equipment besides a sturdy pair of kicks".
Start with short 10-15 minute walks and gradually work up to 30-45 minutes. Brisk walking is an excellent way to meet your weekly aerobic activity goals while remaining sustainable over time.
Consider yoga and swimming. These activities combine gentle resistance training with stress relief. Since stress can exacerbate PCOS symptoms, practices like yoga can address both the physical and emotional aspects of the condition.
Ease into exercise gradually. Begin with 2-3 sessions per week, aiming for a moderate level of exertion - about 7 out of 10 on your personal effort scale. Dr. Rebecca Robinson, a sports medicine expert, advises:
"PCOS can mean that you have a tendency to find losing weight harder and you can have a higher risk of diabetes or central obesity, as one of the hallmarks of the condition is insulin resistance... So, physical activity in combination with good nutrition is one of the best, medically-advised ways of managing PCOS, because it enhances your metabolism and can therefore help with weight loss".
Listen to your body and adjust for your menstrual cycle. Align your workouts with your energy levels during different phases of your cycle. For example, focus on high-intensity or strength exercises during the follicular and ovulatory phases, and opt for lighter activities like yoga during the luteal and menstrual phases.
The key is consistency, not perfection. Building sustainable habits that work for you is far more effective than extreme routines that lead to burnout.
Medications That Can Help with PCOS Weight Loss
Managing PCOS often starts with diet and exercise, but sometimes hormonal imbalances and metabolic issues make weight loss especially tough. In such cases, medications can play a supportive role. By working closely with a healthcare provider, you can create a treatment plan that tackles these challenges while complementing your lifestyle efforts. These medications aim to address the root causes of weight struggles, such as insulin resistance and hormonal imbalances, providing a more targeted approach.
Metformin: Addressing Insulin Resistance
Metformin is a commonly prescribed medication for managing insulin resistance, a key factor in PCOS. Research shows that up to 80% of women with PCOS experience insulin resistance, and metformin can help by lowering fasting insulin levels, leading to an average weight loss of about 5.8%.
Starting metformin at a low dose can help minimize side effects like nausea, diarrhea, bloating, or a metallic taste. Taking it with meals often reduces these effects, and if diarrhea persists, extended-release versions like Glumetza or Fortamet might be a better fit. However, it’s important to be aware of potential risks, such as vitamin B12 absorption issues or, in rare cases, lactic acidosis - a serious condition with high mortality risk.
Since improved insulin sensitivity can restore ovulation, sexually active individuals who aren’t planning a pregnancy should use contraception. Metformin isn’t suitable for those with kidney problems, congestive heart failure, or liver issues.
For those seeking affordable access, Oana Health offers metformin starting at $22 per month, with options to combine it with other treatments like spironolactone.
Spironolactone: Balancing Hormones
Spironolactone is another option for managing PCOS symptoms, particularly elevated androgen levels, which affect 75–90% of individuals with the condition. This medication works by blocking testosterone's effects, which can contribute to weight gain (often due to fluid retention) and symptoms like acne, hirsutism, and hair loss. Many people notice improvements in hirsutism within 2–6 months.
Often prescribed alongside birth control, spironolactone is used off-label for PCOS. However, it’s not safe for those who are pregnant, breastfeeding, or planning to conceive, as it may pose risks to a developing male fetus. It should also be avoided by individuals with Addison's disease or urinary issues, and common side effects include dizziness, nausea, and irregular periods.
For accessible pricing, Oana Health offers spironolactone at $14 per month, making it an affordable option for hormonal management.
GLP-1 Medications: Curbing Appetite
GLP-1 receptor agonists are another promising option for PCOS-related weight challenges. These medications help lower blood sugar, reduce appetite, and improve insulin sensitivity, leading to noticeable weight loss. For example, studies show that 76% of users taking a 3mg dose of liraglutide achieved over 5% weight loss, compared to 30% for placebo and 44% for orlistat. Semaglutide has shown even greater results in weight reduction.
A meta-analysis highlights that GLP-1 receptor agonists may outperform metformin in improving insulin sensitivity, reducing BMI, and decreasing abdominal circumference in women with PCOS. Beyond weight loss, they can also help regulate menstrual cycles, lower inflammation, and reduce cardiovascular risks.
To minimize side effects like nausea, vomiting, or diarrhea, it’s best to start with a low dose and increase gradually. It’s also crucial to ensure proper nutrition during treatment, ideally with guidance from a dietitian. Women of reproductive age should use effective contraception and stop GLP-1 therapy at least two months before trying to conceive, as these medications are not safe during pregnancy. Screening for conditions like pancreatitis, diabetic retinopathy, or thyroid cancer is essential before beginning treatment.
Oana Health provides oral semaglutide GLP-1 therapy for $199 per month, with options to combine it with metformin for a more comprehensive approach to managing PCOS.
Ultimately, finding the right combination of medications requires collaboration with your healthcare provider. By addressing specific symptoms and monitoring for side effects, these treatments can work alongside lifestyle changes to help tackle PCOS-related weight challenges effectively.
Conclusion: Creating a Complete PCOS Weight Loss Plan
Managing PCOS-related weight challenges isn't just about shedding pounds - it's about improving overall health, balancing hormones, and supporting a healthy metabolism. Dr. Suzanne Fenske puts it best:
"The goal isn't simply short-term weight loss but long-term health, regular menstrual cycles, hormonal balance, and a well-functioning metabolism. A crash diet won't get you there; effective treatment requires a multifactor approach and time to build sustainable habits".
Even small changes can make a big difference. Research shows that losing just 2% to 5% of your body weight can significantly reduce PCOS symptoms.
A successful PCOS weight loss plan should include four key elements: diet, exercise, medications, and professional support. Start with a low-glycemic, balanced, and anti-inflammatory diet. Pair this with at least 150 minutes of moderate-intensity exercise weekly, incorporating both cardio and strength training twice a week. When lifestyle adjustments alone aren't enough, medications like metformin, spironolactone, or GLP-1 therapies can help address insulin resistance and hormonal imbalances effectively. Together, these strategies create a strong foundation for long-term health.
Working with healthcare professionals, including primary care providers, gynecologists, endocrinologists, and registered dietitians, can enhance your plan. As Amanda Stathos, a Clinical Dietitian at Johns Hopkins' Sibley Memorial Hospital, explains:
"If you are diagnosed with polycystic ovary syndrome, it doesn't mean that you are destined to have poor health. There is a lot you can do to take charge, minimize symptoms and keep yourself healthy".
Patience is key. Studies suggest that combination therapies often take over six months to show meaningful improvements in insulin resistance and other metabolic markers. Building sustainable habits and staying adaptable will ensure long-term success.
For those seeking accessible care, Oana Health offers comprehensive PCOS management solutions, including telehealth consultations and home delivery, making it easier to take control of your health.
