Alcohol is a powerful inhibitor of gluconeogenesis. It forces part of the gluconeogenic metabolic process into reverse. This means that if all the glucose in the blood is being derived from gluconeogenesis then the consumption of alcohol will inevitably cause the blood glucose level to fall. The alcohol also stops ketone body production, thus leaving the brain without fuel. A person who is ketotic is 100% reliant on gluconeogenesis to maintain adequate levels of glucose in the blood. If, under these circumstances alcohol is taken, the person can become disorientated and might lose consciousness, not just from the alcohol, but from low blood sugar. Does this happen to the point of extreme danger to everyone every time. No. Will it happen to you? You will not know until it happens!
