From a young age, Juliana was prone to dips in her mood. Mood disorders run in my family so I assumed she had just inherited this trait from me. We noticed that if she didn’t exercise, she was much more likely to suffer a low mood, so we taught her that she needed to move every day to help keep her on an even keel. And that helped her.
Then we tried low carb eating, and her mood problems have disappeared. I also feel an elevated mood eating low carb. Both of us still exercise, but neither of us feels as dependent on doing so to regulate how we feel.
