LOW CARB DIETS are particularly bad for the hormonal system of females. Cutting out carbs is not necessarily the best option, and here's why:
A particularly useful thyroid hormone (known as T3) is responsible for converting cholesterol into the hormone Progesterone, which is the "youth-associated, protective hormone" known to help with hair growth, clear skin, and overall hormonal balance. The key is that this entire process depends upon glucose or sugar that largely comes from carbohydrates. Without carbs, the body becomes stressed and produces more estrogen, which ages the body and causes a myriad of other health effects when it's dominant.
Thus, going on a low carb diet can lead to breast tenderness, PMS, headaches, an increase in fat tissue, a decrease in muscle tissue, hair loss, wrinkles, cravings, high blood sugar (yep!), a damaged metabolism, and hormonal chaos.
If you're thinking low carb is the best, you may want to change that misconception to a "no processed foods" lifestyle. Processed foods are much worse for the body than real, wholesome carbs like fruits and root vegetables (i.e., carrots, potatoes, turnips, beets, peppers, squash, etc.). Fruits and roots contain real sugar that the body recognizes and prefers in order to operate efficiently and not have to age and break down the body.
So do yourself a favor and avoid anything processed, rather than avoiding real carbs that are nourishing to your body.
