The Claim

In euthymic adults with bipolar disorder, daily blood ketone levels are positively correlated with self-rated mood (r = 0.21) and energy (r = 0.19), and inversely correlated with impulsivity (r = -0.30) and anxiety (r = -0.19).

In plain English

In adults with bipolar disorder who are not currently experiencing mood episodes, higher levels of ketones in the blood are associated with slightly higher self-reported mood and energy, and lower self-reported impulsivity and anxiety.

See the scientific wording

In a subset of euthymic adults with bipolar disorder, daily blood ketone levels are positively correlated with self-rated mood (r = 0.21) and energy (r = 0.19), and inversely correlated with impulsivity (r = −0.30) and anxiety (r = −0.19), suggesting a possible link between ketosis and subjective emotional states.

Why this might work

When ketones rise in the blood, the brain switches from using sugar to using ketones for energy. This makes brain cells more efficient at producing power and reduces excess signaling chemicals that cause overactivity. As a result, mood improves, energy increases, and feelings of impulsivity and anxiety decrease.

  1. Study: A pilot study of a ketogenic diet in bipolar disorder: clinical, metabolic and magnetic resonance spectroscopy findings

    In people with bipolar disorder who aren't having a mood episode, the study found that on days when their blood had more ketones, they tended to feel a little better, more energetic, and less impulsive or anxious — even though their official doctor assessments didn't change.
