You are welcome!

Unfortunately for me the diet did help but it did not help to the degree where I can get rid of my cpap. I am pretty sure I had sleep apnea when I was a teenager but it was around 29-30 before I had a sleep study and got on a cpap. Sleep studies were a fairly new thing way back then and there were only a very few sleep clinics scattered around the country at that time. Now they are in nearly every hospital. Since losing weight I can now sleep on my side without it but on my back still require it. I have been using a cpap of one form or another for over 40 years.

The early ones were manual adjustment, my current two (one travel, one home) are auto adjust but I still have to set the maximum pressure to keep from "blowing my gut up" and I think they may be Bipap but would have to look the model numbers up to be sure.

There are several different causes of sleep apnea from what I have read. Believe it or not a fat tongue is one of them. A fat tongue will somewhat obstruct the airway, particularly when sleeping on the back, and cause apnea. Losing a little weight the body tries to lose the most dangerous fat first (visceral or organ fat). So losing a little weight will help a lot of people with sleep apnea but not everyone. Or it might help almost everyone that is overweight, but might not cure the problem completely.

I was skinny as a teenager and young adult and yet had sleep apnea (and pretty skinny now, 175-180 currently at 6'2" from about 265# 6 years ago when started eating low carb ketogenic). So overweight is not the only cause. Glad it helped you!

My understanding. I am no expert, that is for sure.
