How to Lose Weight With PCOS: 12 Helpful Tips

If you have polycystic ovary syndrome (PCOS), changing your diet, exercise routine, and lifestyle may help you reach and maintain a moderate weight.

Polycystic ovary syndrome (PCOS) is a condition characterized by hormonal imbalances, irregular periods, and the development of small cysts on one or both ovaries.

Globally, this condition may affect 4–20% of women of reproductive age (1Trusted Source).

The hormonal imbalances, insulin resistance, and inflammation related to this condition can make it difficult for people with PCOS to lose weight.

However, even a small weight loss of about 5% can improve insulin resistance, hormone levels, menstrual cycles, fertility, and overall quality of life in people with PCOS (2Trusted Source).

Here are 12 helpful tips for losing weight with PCOS. 

1. Reduce your carb intake

Decreasing your carb consumption may help manage PCOS because of carbs’ impact on insulin levels.

Insulin resistance occurs when your cells don’t respond normally to the hormone insulin. Anywhere from 35% to 80% of people with PCOS experience this.

Insulin is necessary for blood sugar regulation and energy storage in your body. Research associates high levels of insulin with increased body fat and weight gain in the general population and in people with PCOS.

In one study, people with obesity, PCOS, and insulin resistance first followed a 3-week diet of 40% carbs and 45% fat and then a 3-week diet of 60% carbs and 25% fat. Protein intake was 15% of total daily calories during each phase.

While blood sugar levels were similar during the two phases of the diet, insulin levels went down 30% during the lower carb, higher fat phase.

What’s more, a low glycemic diet may benefit people with PCOS. The glycemic index is a measurement of how quickly a particular food raises blood sugar.

According to a 2021 review, low glycemic diets could reduce insulin resistance, fasting insulin levels, and belly fat in people with PCOS more effectively than high glycemic diets.


Eating a low glycemic, low carb diet may reduce insulin levels in people with PCOS. In turn, this could help with weight loss.

2. Get plenty of fiber

Because fiber helps you stay full after a meal, a high fiber diet may promote weight loss in people with PCOS.

In the Africa, the Dietary Reference Intake for fiber is 14 grams (g) per 1,000 calories, or around 25 g per day for women. However, most Africans consume only about 15 g of fiber per day.

In one study, higher fiber intake was linked to lower insulin resistance, less total body fat, and less belly fat in people with PCOS — but not in those without PCOS.

In another small study in 57 people with this condition, higher fiber intake was associated with lower body weight.


For people with PCOS, a diet high in fiber may help reduce insulin resistance, body weight, and excess body fat.

3. Eat enough protein

Protein helps stabilize blood sugar and increases feelings of fullness after a meal.

It may also aid weight loss by reducing cravings, helping you burn more calories, and regulating hunger hormones.

In one small 2012 study, 57 people with PCOS consumed either a high protein diet consisting of more than 40% of calories from protein and 30% from fat or a standard diet consisting of less than 15% protein and 30% fat. 

Individuals in the high protein group lost an average of 9.7 pounds (4.4 kilograms) after 6 months — significantly more than those in the control group.

If you’re concerned you’re not getting enough protein, you can add it to your meals or choose high protein snacks. Healthy high protein foods include eggs, nuts, dairy, meat, and seafood.


Higher protein intake may boost weight loss, especially for people with PCOS. Try adding healthy high protein items such as eggs, nuts, and seafood to your diet.

4. Eat healthy fats

Having plenty of healthy fats in your diet may help you feel more satisfied after meals and tackle weight loss and other symptoms of PCOS.

In one study in 14 people with PCOS, following a high fat ketogenic diet led to significant reductions in body weight, body mass index (BMI), and belly fat after 12 weeks.

Additionally, although fats are rich in calories, adding healthy fats to meals can expand stomach volume and reduce hunger. This may help you eat fewer calories throughout the day, according to one older study.

Avocado, olive oil, coconut oil, and nut butter are some foods that contain healthy fats. Combining healthy fat with a protein source can further increase the filling effects of meals and snacks.


Eating more healthy fats may be beneficial for people with PCOS. Studies have linked higher fat intake to reduced hunger and a greater loss of body fat.

5. Eat fermented foods

Healthy gut bacteria may play a role in metabolism and weight maintenance. 

Studies suggest that people with PCOS may have fewer healthy gut bacteria than those without this condition. 

Emerging research also suggests that certain probiotic strains may have positive effects on weight loss.

However, other recent research has turned up mixed results.

Still, eating foods high in probiotics — such as yogurt, kefir, sauerkraut, and other fermented foods — may help increase the number of beneficial bacteria in your gut. 

You can also try taking a probiotic supplement, though research is lacking on which strains may be most beneficial for those with PCOS.


People with PCOS may have lower numbers of beneficial gut bacteria. Eating foods rich in probiotics or taking a probiotic supplement may support your gut bacteria, thus aiding weight loss. However, more research is needed.

6. Practice mindful eating

People with PCOS may have tried many diets and are three times more likely to have eating disorders than people without PCOS.

Mindful eating is one potential solution. It promotes an increased awareness of bodily cues such as hunger and fullness.

Mindfulness-based approaches to food may help address potentially problematic eating behaviors — especially binge eating and emotional eating. 

What’s more, studies suggest that mindful eating practices may be linked to weight loss.


Mindful eating helps promote awareness of internal eating cues and may contribute to weight loss. It may be especially helpful for people with PCOS, who are much more likely to experience eating disorders than people without the condition.

7. Limit processed foods and added sugars

Another tip to lose weight with PCOS is to cut down on your intake of less nutritious foods.

Processed foods and added sugars may raise blood sugar levels and increase your risk of insulin resistance, which is linked to obesity.

People with PCOS may process sugar differently than those without it. Research shows that women with PCOS experience larger spikes in blood sugar and insulin levels after consuming the same amount of sugar as women without this condition. 

Studies also indicate that minimally processed foods raise blood sugar less than highly processed foods and are more satisfying. 

Furthermore, experts recommend that people with PCOS limit their consumption of added sugars and refined carbs. This may help them manage symptoms and maintain a healthy body weight. 

Foods high in added sugar and refined carbs include cakes, cookies, candy, and fast food.


Processed foods such as refined carbs and added sugars increase blood sugar levels, which can lead to weight gain.

8. Reduce inflammation

Inflammation is your body’s natural response to infection or injury.

But chronic inflammation, which is common in people with PCOS, is linked to obesity. Sugar and processed foods may contribute to inflammation.

In one small 2013 study, 16 women with PCOS who took a one-time dose of 75 g of glucose — a particular type of sugar — had higher blood markers for inflammation than those without this condition. 

A diet like the Mediterranean diet — which is high in fruits, vegetables, whole grains, olive oil, and omega-3-rich foods such as fatty fish — may protect against inflammation.


Inflammation is common in people with PCOS and has been linked to obesity. Eating a diet that includes plenty of whole foods — especially fruits and vegetables — may guard against inflammation.

9. Exercise regularly

Exercise is a well-known strategy for increasing weight loss.

In one small 12-week study, 16 women did 45–60 minutes of cardio 3 times per week. Those with PCOS lost 2.3% of their body fat, compared with 6.4% in the control group.

While people with PCOS lost less fat than those without this condition, the exercise regimen did result in loss of belly fat and improvements in insulin sensitivity.

Weight training has also been shown to be beneficial for people with PCOS.

In one small study, 45 people with PCOS did weight training 3 times per week. After 4 months, they had lost belly fat and gained lean body mass while reducing testosterone and blood sugar levels.


Both cardio and weight training exercises may help people with PCOS decrease body fat and improve insulin sensitivity.

10. Get enough sleep

Sleep is increasingly acknowledged as central to overall health.

If you have PCOS, you may experience sleep disturbances, including excessive daytime sleepiness, sleep apnea, and insomnia. 

Lack of sleep has been shown to increase the activity of hormones that drive hunger, such as ghrelin and cortisol, which may cause you to eat more throughout the day.

In fact, insufficient sleep is associated with a higher risk of having overweight or obesity.

One study in 156 people in a weight loss program found that markers of poor sleep quality — including more awakenings, lower sleep efficiency, and longer time to fall asleep — were associated with less weight loss and lower odds of adhering to recommendations for physical activity.

Additionally, studies have linked better quality sleep to fat loss. 

In one study, healthy adults who slept less than 6 hours per night had a 12% higher risk of developing belly fat than those who slept 6–8 hours per night. 


Lack of sleep is linked to obesity. Studies in healthy adults suggest that increasing your total time asleep can reduce body fat and promote weight loss.

11. Manage your stress

Because stress is a risk factor for weight gain, managing or reducing stress may help you manage your weight. 

Stress increases levels of cortisol, a hormone that your adrenal glands produce. Chronically high cortisol levels are linked to insulin resistance and weight gain.

Chronic stress also increases your risk of gaining belly fat. In turn, belly fat increases inflammation, which triggers your body to make more cortisol, creating a vicious cycle.

To lower your cortisol levels, focus on stress management practices. 

Studies suggest that techniques such as meditating, practicing yoga, and spending time in nature can help lower cortisol levels.


High cortisol levels from chronic stress are linked to insulin resistance and belly fat. Managing stress through yoga, meditation, and time outdoors may help lower cortisol levels.

12. Consider supplements 

If you have PCOS, several supplements may help you manage your weight and symptoms. 

Myo-inositol is a supplement that may lead to weight loss in people with PCOS. Inositol is a type of sugar that helps improve insulin sensitivity. Myo-inositol is a specific form of inositol.

Interestingly, one review of 15 studies found that inositol supplementation could be linked to a reduction in BMI.

Carnitine, an amino acid found in meat, may also lead to weight loss.

A review of nine studies concluded that carnitine supplementation could effectively reduce fasting blood sugar levels and BMI in people with PCOS.


Myo-inositol and carnitine supplements may help people with PCOS lose weight and manage certain symptoms.

The bottom line

PCOS can it make it difficult for people to lose weight. 

A balanced, nutritious diet — low in inflammatory foods such as refined carbs and highly processed foods and rich in whole foods, protein, healthy fats, and fiber — may aid weight loss. Certain supplements may help as well.

It’s also important to consider lifestyle factors. Regular exercise, stress management, and sleep are all important to weight loss.
