Developed in the s by Hugh Conklin a faith healer in Battle Creek, Michigan, who treated children with epilepsy by depriving them of all foods by giving them nothing but water for up to 25 days, this diet induces a state that mimics carbohydrate starvation 1. As medications became available and effectively addressed seizures, the ketogenic diet fell out of favor. During the last few decades, researchers and clinicians have learned that ketogenic diet can be useful in children and adults with refractory epilepsy and a variety of other conditions. Ketosis is also produced during fasting periods, which is known as fasting ketosis. Recently, the combinations of nutritional ketosis and fasting ketosis, as well as nutritional ketosis alone, have been used as resources for weight loss management 3. And many Americans are using it to lose weight 4. The keto diet often termed ketogenic diet is a very low-carb, high-fat diet that shares many similarities with the Atkins and low-carb diets. Ketogenic diet involves drastically reducing carbohydrate intake, and replacing it with fat. The reduction in carbs puts your body into a metabolic state called ketosis. When this happens, your body becomes incredibly efficient at burning fat for energy. It also turns fat into ketones in the liver, which can supply energy for the brain.
Polycystic ovary syndrome PCOS is the most common endocrine disorder affecting women of reproductive age and is associated with obesity, hyperinsulinemia, and insulin resistance. Because low carbohydrate diets have been shown to reduce insulin resistance, this pilot study investigated the six-month metabolic and endocrine effects of a low-carbohydrate, ketogenic diet LCKD on overweight and obese women with PCOS. They were instructed to limit their carbohydrate intake to 20 grams or less per day for 24 weeks.

Some researchers suggest that there are not in fact any metabolic advantages in low-carbohydrate diets and that weight loss results simply from reduced caloric intake, probably due to the increased satiety effect of protein The heart and brain are the only two organs that can burn ketones, so the other possibility, not yet proven, is that ketones, like other nutrients such as glucose and fatty acids, suppress hunger directly by working on the brain. A primary feature of insulin resistance is an impaired ability of muscle cells to take up circulating glucose and also the ability to slow down hepatic glucose output may be compromised. Ghrelin is a hormone produced by cells lining the stomach that stimulate appetite. Long term effects of ketogenic diet in obese subjects with high cholesterol level. Although ketosis is believed to produce the anticonvulsant effects of KDs, the mechanisms involved are still unknown [ 67 ]. She stumbled upon a keto cookbook and signed up on the two-week keto low-carb challenge. Metformin therapy in polycystic ovary syndrome reduces hyperinsulinemia, insulin resistance, hyperandrogenemia, and systolic blood pressure, while facilitating normal menses and pregnancy.
