Why do i crave carbs so much when i have my period?
Biology says that the blood used for this monthly occurance, takes up the energy that usually keeps you up, and going. With the blood, you are also discharging important minerals adn other nytrients that your body needs, so they get replaced monthly, with foods your body "craves" for you to quickly replace what was lost. Sure, I'm a Guy, but hey, whats the harm in knowing this stuff?
the hormone levels get really high when you are menstruating . each persons craves something different. many women crave chocolate to help with the feelings, and you seem to be craving carbs.
carbs help increase serotonin levels in brain, as well as being our fav. "comfort foods"..
You're body is working overtime and wants more energy so it craves the most apparent thing- sugar and carbs. That's why it's best to eat really healthy (fruits/veggies) on your period to get natural energy and nutrition.
