@mcscx First of all: quotation needed, I can't verify what they mean with "short-term". Also, 100-200 mW/cm² is - as it says - a pretty high dosage.
Could it be this? https://social.umeahackerspace.se/url/31080
From the abstract: "Statistically, there was a significant (P < .01) decrease only of food consumption during the 5-mW/cm2 exposure; other variables were not significantly different between exposed and control groups."
