Researchers in France believe subtle shift in facial attractiveness is down to changes in blood sugar and insulin
A French study found people who eat a breakfast high in refined carbs (like pastries and juice) were rated less attractive than those who ate whole grains (like wholemeal toast) for breakfast. This might be because refined carbs affect blood sugar and insulin, potentially impacting skin health and sex hormones. The researchers suggest swapping refined carbs for unrefined options to improve both health and attractiveness.
I like your thinking. I currently add seeds and cinnamon, with a topping of Greek yogurt and a banana. So I switch the seeds for nuts and see if the sexual flood gates open. If not, try a different grain as a base. And I'd be doing it for science!
Alternate explanation: attractive people are more likely to be well off and have the means to take care of their health and attractiveness.
Poor ugly people eat shitty carb laden food because that’s what they can afford. Also being poor costs you 11 IQ points due to the stress of being poor and leads to less executive function left over to discipline one’s food intake even could they afford it.
