My doc told me (last year when I was being tested for Sleep Apnoea)
that there was a reasonably strong correlation between lack of good
(restful) sleep and insulin resistance.

Insulin resistance is mainly due to life style factors of eating too much
and inactivity, which would then set a person up for sleep problems. Lack of
sleep may then aggravate the insulin resistance.
Just as it is hard to lose weight because of being insulin resistant, a
person shouldn't blame the symptom before the life style factors that caused
the weight gain in the first place.

treating my apnoea and got the first good sleep I had managed in years
I began to lose weight WITHOUT making any changes to my diet and
exercise regime.

Do you think that in your case that lack of good sleep causes insulin
resistance and metabolic syndrome? I think that relieving the symptom of
lack of sleep affected the other factors in good favor.

circumstances outside my control) the loss stopped again.

Yes. Stress is not good for sleep.

Doesn't
seem to matter that eating and exercise patterns are no different from
those I had when I was losing, if I'm not sleeping well (and I'm not)
then I won't lose.

In your case, a lack of sleep may be more of a cause than a symptom, but
I believe that for the majority of people, lack of sleep is another self
feeding symptom of metabolic disease.

I also have to wonder (without extensively reviewing these studies
myself) how well the covariate of sleep apnea or other obstructive
airway disorders were controlled for in these studies. It's well-known
that being fat can increase one's risk for airway obstruction, which
can decrease restful sleep. So, it would make sense that the fatter you
are, the less restful sleep you get...

I concur. Before I started, I had bad airway obstruction when I slept.
My wife was very concerned. With 20 lbs off, my wife notes that I still
breathe badly while asleep, but nowhere near as bad as before.
Additionally, I am sleeping a lot better, though there are too many
variables to really explain it (new apartment, new pillow, getting
accustomed to my wife's cat, weight loss, vitamins, etc). I am looking
forward to sleeping better as I get closer to goal. One more bit of
motivation.
