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.

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).
