Ketogenic diet for mitochondrial disease: potential role in treating the Multiple Symmetric Lipomatosis phenotype associated with the common MT-TK genetic mutation
Orphanet Journal of Rare Diseases volume 17, Article number: 12 (2022)
We read with appreciation the succinct and informative systematic review by Zweers et al.  on the effect of the Ketogenic Diet and/or the Modified Atkins Diet on various mitochondrial disease associated phenotypes.
While this review covered studies pertaining to epilepsy, skeletal and heart muscle, tonus dysregulation, movement disorder, developmental delay/intellectual disability, food intake, weight gain/growth, and hair growth, we note that the multiple symmetric lipomatosis phenotype, frequently associated with the MT-TK genetic mutation, was not covered.
We would like to highlight that a version of the ketogenic diet was employed successfully, along with other simultaneous lifestyle interventions, in treating a disabling multiple symmetric lipomatosis phenotype. This successful intervention was reported in 2020  and warrants further consideration by care providers whose patients are in a similar predicament, and similarly motivated.
