Yes, see Why We Sleep by Matthew Walker:

The upshot of all this work can be summarized as follows: short sleep (of the type that many adults in first-world countries commonly and routinely report) will increase hunger and appetite, compromise impulse control within the brain, increase food consumption (especially of high-calorie foods), decrease feelings of food satisfaction after eating, and prevent effective weight loss when dieting.

Lack of sleep increases insulin resistance[1]. Insulin resistance can negatively influence weight loss AFAIK.

Interesting. I alternate periods of good diet to periods of less healthy diet. I have been sleeping less than 6h a day fir for most of my adult life. 6h of sleep for me are ideal. But when I do regular relaxations (20 min) I can easily sleep 4.5h with no problems.

I had periods in the past when I sleep less 3 hours for 5 days and end up "recovering" with a 9h sleep during the weekend. I was not at my best though.

I never noticed any particular patterns between my weight and my sleep.

In the last month though lack of sleep and more carbs seem to start generating joint pains (hopefully it is just temporary).

Yes, one is you will ha e less will power to resist sugar

Interestingly, I cut out sugar really strictly a few months back, including no fruit. A side effect is that I didn't nee caffeine to kick start me at work in the mornings.
