    • High Fat Diets Ruin Sleep


      From ScienceDaily

      Research presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB) finds that prolonged exposure to a high-fat diet reduces the quality of sleep in rats.

      Using radio-telemetry, the authors measured 24-hour sleep and wake states after rats consumed a high fat diet for 8 weeks. Compared to rats that consumed a standard laboratory chow, the rats on the high-fat diet slept more but sleep was fragmented. The increased sleep time of the rats on the high-fat diet occurred mainly during the normally active phase of the day, resembling excessive daytime sleepiness observed in obese humans.

      According to lead author, Catherine Kotz, "Studies in humans indicate a relationship between sleep quality and obesity. Our previous work in animals shows a link between good quality sleep, resistance to weight gain and increased sensitivity to orexin, a brain chemical important in stabilizing sleep and wake states. The current studies show that after high-fat diet-induced weight gain in rats, sleep quality is poor and orexin sensitivity is decreased. These findings suggest that poor sleep associated with weight gain due to a high-fat diet may be a consequence of reduced orexin sensitivity."

      These studies highlight the impact of weight gain on sleep quality and a potential brain mechanism underlying these diet and weight-gain induced changes in sleep behavior.

        This is the telling portion of the study. They didn't just adjust the macro ratios of the rats diet, they overfed them. Overfeed rats with fat, overfeed them with carbs, overfeed them with protein so that they become obese and guess what? Bad things happen. Did we really need a study for this? This study provided no benefit, but we take it a step further and allow it to become harmful because the media drops terrible sound bites and headlines on the general public that read "High Fat Diets Ruin Sleep".

        This article is grossly negligent, most people aren't equipped to decipher what really happened here, and this only perpetuates the prevalence of low fat products lining supermarket shelves.

        Shame.

        I agree completely. I get about 50% of my calories from fat (what most people would call a high fat diet) and have never slept better.

        Another flaw is it doesn't mention types of fat. Sure give someone 40% of their diet in trans fat and it will def mess stuff up.

        I agree with other post.
        My sleep is amazing on a high fat diet.
