There is not one reason the body requires carbs. Simple as that and if one truly learns this and knows the body only requires protein and fat for true survival…well DUH…take some big conclusions from real nature and its real science.
Tons of reasons sugar is a drug. Physically. Emotionally. Convenience eating. 24/7 eating. No real nutrition so you keep eating cause your body is truly starving. You are addicted because your body is dying inside, begging for more food all the time, praying for itself to be fed correctly yet it doesn’t come. Then the body starts to rebel. Illness kicks in. See, the body says, I’ll show you…what do you do now matters. Take pills for symptoms and live worse or clean up your act? Bodies never came with owner manuals. It came with simple science and then humans walked far far away from that.
