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!
