The ketogenic diet has recently been investigated a great deal for how it may help prevent or even treat certain cancers. One study found that the ketogenic diet may be a suitable complementary treatment to chemotherapy and radiation in people with cancer. This is due to the fact that it would cause more oxidative stress in cancer cells than in normal cells.
But when you consume a high-carbohydrate diet, your brain often can't convert enough glutamate into GABA because it's using glutamate as an energy source. This imbalance can lead to neurotoxicity, and this impaired functioning could potentially lead to brain fog. For reasons not completely understood, ketosis seems to favor an increased production of GABA, which can lead to reductions in neurotoxicity and, therefore, brain fog.

Despite its explosive popularity, there’s a lot of confusion about what the ketogenic (keto) diet really is. “Many people think they’re following a keto diet when they’re really just consuming a low-carbohydrate diet,” says Patti Urbanski, MEd, RD, CDE, a certified diabetes educator with St. Luke’s Hospital in Duluth, Minnesota. “So one person’s ‘keto diet’ may look very different than another’s.”
The research on how diet affects PCOS is minimal, but there is one compelling study on the ketogenic diet and women with PCOS. In this study, five overweight women ate a ketogenic diet (20 grams of carbohydrates or less per day) for 24 weeks. The results were astounding — average weight loss was 12%, free testosterone decreased by 22%, and fasting insulin levels dropped by 54%. What’s even more impressive is that two of the women became pregnant despite previous infertility problems.
