Just for context, I posted this study since I was intrigued by this[0] recent HN comment about an anecdotal apnea training effect on weight and then came across this study. I'm using the Apnea Trainer app on iOS, but too early to say how it affects my weight.

I'm going to get a PowerBreathe device[1] as used here, since I am also dealing with hypertension.
