Polycystic ovary syndrome (PCOS) is the most common endocrine disorder among women of reproductive age, and is frequently associated with central obesity, insulin resistance, and dyslipidemia. Because recent evidence demonstrates that a low carbohydrate ketogenic diet (LCKD) leads to weight loss and improvements in insulin sensitivity, we conducted this uncontrolled trial of the diet for PCOS.

A Pilot Trial of a Low-Carbohydrate, Ketogenic Diet in Patients with Type 2 Diabetes
The study focused on overweight individuals with BMI >25 and being treated with OHA (oral hypoglycemic agents) or insulin that were placed on a LCKD (low carbohydrate ketogenic diet) for 16 weeks. Anthropometric changes include: Body weight = -10%, BMI = -10%, Waist circumference = -7%, Body fat % = -3%, Systolic BP = -9%, Diastolic BP = -15%, Heart Rate = -12%, HDL = no change.
A Low-Carbohydrate, Ketogenic Diet versus a Low-Fat Diet To Treat Obesity and Hyperlipidemia: A Randomized, Controlled Trial
Compared with a low-fat diet, a low-carbohydrate diet program had better participant retention and greater weight loss. During active weight loss, serum triglyceride levels decreased more and high-density lipoprotein cholesterol level increased more with the low-carbohydrate diet than with the low-fat diet.
A Low-Carbohydrate, Ketogenic Diet for Type 2 Diabetes Mellitus
The LCKD reduced glycemia, body weight and serum triglycerides in type 2 diabetic patients but close medical supervision was required to adjust diabetic and blood pressure medications.
A Low-carbohydrate, Ketogenic Diet to Treat Type 2 Diabetes
In a study of overweight individuals with type 2 diabetes, the LCKD (low carbohydrate ketogenic diet) improved glycemic control in patients with type 2 diabetes such that diabetes medications were discontinued or reduced in most participants. Other results include: mean body weight decreased by 6.6% and fasting serum triglyceride decreased 42%.
Effects of Two Weight-loss Diets on Health-related Quality of Life.
Mental aspects of HRQOL (health related quality of life) improved more in participants following an LCKD (low calorie ketogenic diet) than an LFD (low fat diet), possibly resulting from the LCKD’s composition, lack of explicit energy restriction, higher levels of satiety or metabolic effects. The factors analyzed were: Physical Functioning, Role-Physical, General Health, Vitality, Social Functioning. The Physical Component Summary score improved similarly in both diet groups. Bodily Pain improved in the LFD group only, whereas the Role-Emotional and Mental Health subscales and the Mental Component Summary (MCS) score improved in the LCKD group only.
A randomized trial of a low-carbohydrate diet vs orlistat plus a low-fat diet for weight loss.
Obese and overweight outpatients were assigned to either a low-carbohydrate ketogenic diet (LCKD) or Orlistat therapy combined with a low fat diet (O + LFD). In a sample of medical outpatients, an LCKD led to similar improvements as O + LFD for weight, serum lipid, and glycemic parameters and was more effective for lowering blood pressure.
A Review of Low-carbohydrate Ketogenic Diets
In response to the emerging epidemic of obesity in the United States, a renewal of interest in alternative diets has occurred, especially in diets that limit carbohydrate intake. Recent research has demonstrated that low-carbohydrate ketogenic diets can lead to weight loss and favorable changes in serum triglycerides and high-density lipoprotein cholesterol. This review summarizes the physiology and recent clinical studies regarding this type of diet.
A Ketogenic Diet Favorably Affects Serum Biomarkers for Cardiovascular Disease in Normal-weight Men
The results suggest that a short-term ketogenic diet does not have a deleterious effect on CVD risk profile and may improve the lipid disorders characteristic of atherogenic dyslipidemia.
Ketogenic diet does not affect strength performance in elite artistic gymnasts
Data suggest that athletes who underwent a VLCKD with adequate protein intake lost weight and improved body composition without any negative changes in strength and power performance. Taken together these results suggest that a properly monitored and programmed ketogenic diet could be a useful, and safe, method to allow the athletes to reach their desired weight categories.
