Low Carb and PCOS
Polycystic Ovary Syndrome (PCOS) is a common disorder that affects 6-7% of the UK female population. Studies have shown that individuals suffering from PCOS suffer not only from a disrupted ovarian function but also disruption to their insulin metabolism. From a genetic perspective there seems to be multiple disorders with different aetiologies making up the overall PCOS symptom range. However, the two most common indicators of PCOS are hyperinsulinaemia and hyperandrogenism.
With about 60% of individuals affected by PCOS being obese through increased abdominal weight and 50% of these individuals suffering from insulin resistance and hyperinsulinaemia, it is ever more important to manage this condition by proper nutrition management.
Studies have shown that individuals suffering from PCOS benefit from following a low carb diet. The reduction in carbohydrate in the diet helps to better manage insulin and this immediately improves any insulin resistance symptoms and helps with weight loss.
