Long ago, the ancient physician Galen noticed something important: When your mood changes, your appetite often changes, too. He thought that appetite was related to “humors,” which were believed to influence health and appetite. However, today we know that it’s brain chemicals such as dopamine and serotonin.
When neurotransmitters are imbalanced, they can disrupt our internal rhythm, triggering constant snacking, unstable energy, and blood sugar highs and lows. Blood sugar swings can also disrupt neurotransmitter function, making cravings, mood swings, and fatigue worse.
