Do you want to stay up all night?
Dr. Oren Froy, and a couple
(They abbreviated "high-fat" to HF. Not sure why, since they didn't abbreviate any of the other terms. Maybe because it sounded way cool that way?)
Their conclusion? "Changes in the phase and daily rhythm of clock genes and components of adiponectin signaling pathway as a result of HF diet may lead to obesity and may explain the disruption of other clock-controlled output systems, such as blood pressure and sleep/wake cycle, usually associated with metabolic disorders."
I knew that not getting enough sleep causes cortisol levels to rise, and the waist to get thicker, and other not-so-great results. It was new to me that an HF diet (hell, if the cool people in white coats abbrev. stuff, I wanna abbrev. stuff 2. I cool) would mess with the body's cycles such as the ability to go to sleep at night and get up in the morning.
Besides insomnia, I don't like the idea of messing with the circadian rhythms in any case. To quote the blog Psychology, "The disturbance of circadian rhythms can lead to such phenomena as hormone imbalance, obesity, psychological and sleep disorders and cancer."
Eating an HF lunch can cause me to crave the Zzzs during my afternoon meetings, but I thought that was normal. And I thought frequent bouts of insomnia were just my lot in life.
Next time, I'll skip the pizza and take a walk at lunch instead.
