The Effect of Three Different Ketogenic Diet Protocols on Migraine and Fatigue in Chronic and High-Frequency Episodic Migraine: A Pilot Study.

AIMS: We aimed to evaluate the efficacy of three different ketogenic diets on migraine and fatigue in chronic and high-frequency episodic migraineurs. METHODS: 76 patients with migraine were treated with the KD for at least three months. Three different KD protocols were used (2:1 KD, LGID, and VLCKD). We evaluated the fatigue severity scale (FSS), migraine frequency, migraine intensity, MIDAS, and HIT-6 at the baseline and 3-month follow-up, and we compared the results. We also correlated the mean FSS reduction with the mean migraine frequency, migraine intensity, BMI, fat mass, free-fat mass, MIDAS, and HIT-6 reduction. RESULTS: FSS improved from 4.977 ± 1.779 to 3.911 ± 1.779 at the 3-month follow-up (p < 0.001). This improvement was significant in both high-frequency and chronic migraineurs. Moreover, the three KD protocols effectively improved migraine intensity, frequency, MIDAS, and HIT-6. There was a mild correlation between mean FSS reduction (p < 0.001), mean MIDAS (p = 0.001), and HIT-6 (p = 0.002) reduction. CONCLUSIONS: The VLCKD, LGID, and 2:1 KD may improve migraine intensity, frequency, and fatigue in chronic and high-frequency episodic migraineurs.

2:1 ketogenic diet and low-glycemic-index diet for the treatment of chronic and episodic migraine: a single-center real-life retrospective study.

AIMS: The evidence supporting the efficacy of dietary preventive therapy in migraine is rising, particularly regarding the ketogenic diet. However, less evidence exists for the Low-Glycemic Index Diet and the 2:1 KD. This retrospective single-center real-life study aims to evaluate the efficacy of a 2:1 ketogenic diet and a Low-Glycemic-index Diet in chronic and high-frequency episodic migraine. METHODS: Sixty patients with high-frequency episodic and chronic migraine were treated with either a Low-Glycemic-index diet (39 patients) or a 2:1 (21 patients) ketogenic diet for three months. We collected data on the migraine frequency and intensity and the MIDAS and HIT-6 scores through the headache diary. Anthropometric measurements (BMI, fat mass, free fat mass, and weight) were also collected and analyzed similarly. Data obtained at the baseline and after three months of each diet were compared. RESULTS: Migraine intensity, frequency, MIDAS and HIT-6 scores, fat mass, weight, and BMI improved in both diet groups. CONCLUSIONS: Both diets are effective in reducing migraine symptoms and migraine-related disability.

Sleep of migraine patients is ameliorated by ketogenic diet, independently of pain control.

OBJECTIVE/BACKGROUND: Migraine patients are frequently affected by sleep complaints. The ketogenic diet (KD) is an option for the treatment of migraine. Our aim was: 1) to assess the effects of KD on sleep complaints in patients affected by migraine and 2) to verify if sleep changes were related to the effects of the diet on headache symptoms. PATIENTS/METHODS: From January 2020 to July 2022 we consecutively enrolled 70 migraine patients who were treated with KD as a preventive therapy. We collected information regarding: 1) anthropometric measures; 2) migraine intensity, frequency and disability; 3) subjective sleep complaints, i.e. insomnia, sleep quality, by the Pittsburgh Sleep Quality Index (PSQI), and excessive Daytime Sleepiness (EDS), by the Epworth Sleepiness Scale (ESS). RESULTS: After 3 months of KD therapy, anthropometric measures considerably changed, i.e. body mass index and free fat mass, and migraine significantly improved, i.e. lower intensity, frequency and disability. Regarding sleep, we observed that insomnia affected a decreased rate of patients (T0: 60% versus T1: 40%, p < 0.001). Similarly, patients with poor sleep were significantly less after KD therapy (T0: 74.3% versus T1: 34.3%, p < 0.001). Finally, EDS prevalence declined at the follow-up (T0: 40% versus T1: 12.9%, p < 0.001). Sleep features modifications were not correlated with migraine improvements and with anthropometric changes. CONCLUSIONS: For the first time we demonstrated that KD may improve sleep complaints in migraine patients. Interestingly, the positive effect of KD on sleep is independent of migraine improvements and anthropometric modifications.
