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).
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
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.
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.
What the research says
1 studyIn 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.
