According to a few studies, the Ketogenic/Keto diet may aid in the treatment of PCOS by enhancing insulin sensitivity, encouraging weight loss, regulating hormones, and promoting regular menstruation.
You might be curious as to whether changing your diet will assist with any of your PCOS symptoms.
Insulin resistance, which controls blood sugar levels and fat accumulation, is a hallmark of PCOS, just like type 2 diabetes. The low-carb, high-fat ketogenic diet is frequently recommended to reduce insulin resistance in those with type 2 diabetes, so it might also be helpful for those with PCOS.
When you follow a low-carb, high-fat diet, your body is forced into a caloric deficit, burning fat for energy instead of carbohydrates. Most people who follow a ketogenic diet limit their daily carbohydrate intake to under 50 grams. Among persons with obesity and type 2 diabetes, studies have identified that keto diets may increase insulin sensitivity, regulate hunger hormones, and encourage weight loss. The benefits of keto diets on PCOS have also been examined in recent research.
It is believed that insulin resistance plays a role in the emergence of PCOS. A ketogenic diet rich in plant foods led to considerably lower blood sugar and insulin levels and superior insulin resistance scores that indicated higher insulin sensitivity in a 12-week study of 14 women with PCOS. The weight, hormone levels, liver function, blood lipids, monthly regularity, and fertility were all observed to have significantly improved in these same trials. To learn more about the long-term effects of keto on PCOS, additional trials with longer durations are required.
But the experts warn that the ketogenic diet also has specific adverse effects. Your cholesterol levels could drastically rise as a result. Additionally, it is incredibly restricting and could be challenging to maintain over time.
However, a less rigorous low-carb regimen might provide comparable advantages. Since insulin resistance is a hallmark of PCOS, managing the condition may benefit from the keto diet’s ability to increase insulin sensitivity.
Researchers have discovered additional benefits of the keto diet for PCOS women, including weight loss, improved sex hormone balance, lower cholesterol and triglyceride levels, regular menstrual periods, and improved fertility. Cycling on and off of keto may increase your body’s sensitivity to high-carb foods because keto remains a fairly restrictive diet for most individuals.
There has to be more investigation on how keto affects PCOS. However, sticking to a lower-carb eating plan for the long term may have some advantages for managing PCOS.
