In one woman with severe PTSD, her mood worsened after 8 weeks on a ketogenic diet, but improved again after she stopped taking a low dose of naltrexone, suggesting a possible interaction between the medication and the diet.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether ketogenic diets alter the pharmacokinetics or clinical effects of low-dose naltrexone in psychiatric populations, leading to changes in mood or symptom trajectories.
A systematic review and meta-analysis of all case reports, cohort studies, and RCTs examining mood changes in patients with PTSD or depression taking low-dose naltrexone while initiating ketogenic diets, comparing outcomes to those on naltrexone alone or ketogenic diets alone.
Whether adding low-dose naltrexone to a ketogenic diet alters mood outcomes compared to ketogenic diet alone in individuals with PTSD.
A double-blind RCT of 60 adults with PTSD on a ketogenic diet, randomized to receive either 4.5 mg naltrexone or placebo daily for 12 weeks, with primary outcome of change in PCL-5 and daily mood ratings, and secondary outcomes of ketone levels and adverse events.
Whether individuals with PTSD on low-dose naltrexone who start a ketogenic diet are more likely to experience mood fluctuations than those who continue standard diets.
A prospective cohort study tracking 100 adults with PTSD on low-dose naltrexone who initiate either a ketogenic or non-ketogenic diet, recording weekly mood changes, ketone levels, and medication adherence over 6 months.
Whether mood instability during ketogenic diet use is more common in individuals taking low-dose naltrexone than in those not taking it.
A matched case-control study comparing 30 individuals with PTSD who experienced mood instability during ketogenic diet use to 30 matched controls without instability, assessing prior or concurrent use of low-dose naltrexone.
That mood instability may occur during ketogenic diet use in individuals taking low-dose naltrexone, prompting clinical monitoring.
A case report documenting mood changes in a patient with PTSD on low-dose naltrexone who initiates a ketogenic diet, with detailed timing, symptom profile, and resolution after medication discontinuation.
