>What is the effect of sleep extension on objectively assessed energy intake in adults with overweight in their usual home environment?
>
>**Findings**
>
> In this randomized clinical trial of 80 adults with overweight and habitual sleep less than 6.5 hours per night, those randomized to a 2-week sleep extension intervention significantly reduced their daily energy intake by approximately 270 kcal compared with the control group. Total energy expenditure did not significantly differ between the sleep extension and control groups, resulting in a negative energy balance with sleep extension.

>The findings suggest that improving and maintaining adequate sleep duration could reduce weight and be a viable intervention for obesity prevention and weight loss program
This makes sense to me. I tend to crave food a lot more when I’m tired.
I wonder if a confounding variable is the *time you eat.* Like if you’re eating late, I’d heard is bad for sleep and if eating late you’re more likely to be consuming more calories.
I first read the title the wrong way round ie eating less means better sleep. I tried 5:2 intermittent fasting where I ate 500kcals on two days a week. I used to go to bed hungry and couldn’t sleep because I was so hungry.
However I agree that the better my sleep, the less stressed I am, the less likely I am to reach for junk food.
True I get up at 1pm when I get to sleep 12hrs on weekends and only have time for 2 meals lol
