Some months back I went to a private clinic to seek help for my growing sleep apnea and snoring issues. They wanted £250 JUST for consultation. Revolted, I left and decided to do what should always been done these days when you have a health problem - research it yourself on pubmed and get your own cure.
You see, doctors are not there too help you, they are there to make money. The only person who really wants to help you is YOU.
Anyway, a few searches later and it had become quite clear that sleep apnea was very strongly "associated" with metabolic syndrome. Which in turn is strongly associated with insulin resistance and carbohydrate consumption. During my snoring troubles I had been on and off high-carb, as I usually am, and was probably more on high-carb than I wanted to admit to myself.
So I went back to zero-carb, which I know I can always count on. I know zero-carb rapidly resolves insulin resistance and metabolic syndrome, which I had hoped would also resolve my snoring. It took only a few days, but zero-carb did a fantastic job of alleviating both my sleep apnea and snoring. Within as little as a week there were substantial improvements, And within 2 weeks almost complete remission. This was accompanied by only mild weight loss.
The moral of the story is that, I firmly believe that for whatever reason, sleep apnea and snoring is caused by insulin resistance.
