I don't know what's up with the OP's situation, but you present a false dichotomy. My doctor advised weight loss (not like I needed another reason) and CPAP. Sleeping well is key to fixing other things in your life that may be contributing the weight gain. It's pretty hard to commit to an exercise program if you have no energy. And in my case, I was consuming caffeinated drinks nonstop just to get a few hours of focus at work. I agree there is a worrisome focus now on managing the downsides rather than fixing the orignal problem. But it's not for lack of trying. Doctors have been hectoring patients to change their lifestyles for decades with little success. Obesity is a complex issue. I will only note that over the last three decades, all the other vices are way down -- alcohol, tobacco, even the use of illegal drugs. But obesity is way up. To me that suggests it's not all about a desire for 'quick fixes' or some generalized failure in knowledge or willpower. Culprits may include pervasive advertising that makes gluttony acceptable, agricultural subsidies, and maybe even some hitherto unknown toxicities in refined sugar. (Victor Lustig of UCSF is making that case very strongly.)
