Because of this, including gluten and dairy in a ketogenic diet can be counter-productive. Low-grade chronic inflammation is a key mechanism in the pathology of PCOS. When left undiagnosed, gluten or dairy sensitivity can undermine the intestinal wall lining. This means that these ingredients are generally best avoided. It’s common for women with PCOS to have a subclinical intolerance to gluten and dairy proteins. A diet that’s designed with PCOS in mind is likely to be more suitable.įor example, a ketogenic diet provides no guidance on the suitability of gluten or dairy beyond their impact on ketosis. Given that the only rule of a ketogenic diet is to reach nutritional ketosis, it’s easy to see the shortcomings in this approach. But increases in very low-density LDL may increase cardiovascular risks. For example, Batch points out that the diet has a favorable effect on HDL-cholesterol levels. The impact on fertility is unclear, and the long-term implications are not well-understood. Batch M.D and colleagues, the benefits of a ketogenic diet are generally not seen beyond 12 months. For women with PCOS more generally though, others urge greater caution.Īccording to Dr. Learn more about the pros and cons of the Mediterranean diet for PCOS here. A ketogenic Mediterranean diet, for example, is popular among healthcare professionals. You need to keep this in mind when assessing the pros and cons.įor example, some experts are open to using a well-formulated ketogenic diet as a first-line treatment for obesity and diabetes. Sex, body weight, age, and health status all impact the risks and benefits of very low carbohydrate diets. This can have a significant impact on the applicability of the results. When looking at ketogenic diet studies, it’s important to look at the characteristics of the participants. They were not pregnant or breastfeeding, and they had no other serious medical conditions. They had a body mass index (BMI) > 25 kg/m2 which is within the overweight range. The PCOS participants in these studies were between the ages of 18 and 45. This last point is often missed by people referencing the Cincione et al. It should be noted that this study also restricted caloric intake to just 600 kcal per day. Patients lost 12.4 lb (5.6 kg) on average and showed other improvements in markers of body composition (waist and hip circumference, etc.). They also saw better sex hormone binding globulin levels and improved insulin sensitivity. They observed improvements in luteinizing hormone and follicle-stimulating hormone. This study restricted caloric intake to 1600 kcal per day. Triglyceride and cholesterol levels also improved. Luteinizing hormone, testosterone, and DHEA levels were reduced. They observed improvements in body composition and insulin regulation. They saw both weight loss and improvements in sex hormone imbalances. Despite these constraints, there are still several pilot studies that show positive results. The size, duration, or other confounding factors limit the clinical significance of the findings. Within the scientific community, the benefits of a keto diet for PCOS are unclear. Pro: Sex Hormones, Metabolic Health, & Body Composition This can help you lose weight, improve your menstrual cycle, and reduce other PCOS symptoms.Ģ. For overweight women with PCOS, this can help with weight loss, irregular periods, unwanted body hair, high blood pressure, and more.Ī ketogenic diet can reduce insulin resistance in women with PCOS. Ketosis can be a powerful way to reduce body fat. This lowers insulin levels and the negative effects of insulin resistance. The body then switches to burning fat by-products (ketones) instead of glucose. Carb intake needs to be so low, that there isn’t enough glucose to meet the body’s energy requirements. It improves PCOS by reversing the effects of insulin resistance. Ī ketogenic diet is a very low carbohydrate diet. Studies also show that insulin is associated with depression. In women with PCOS, insulin resistance contributes to menstrual irregularities and infertility. Insulin resistance is a known risk factor for type 2 diabetes, liver disease, heart attack, and stroke. Overweight and obese women are more likely to be insulin resistant. The severity of insulin resistance largely determines the strength of PCOS symptoms. Pro: Improves Insulin Resistanceīest estimates suggest insulin resistance affects between 30 and 70% of women with PCOS.
