Abstract

Reversing the aging process may yield significant benefits in people with multiple sclerosis (PwMS), as accelerated biological aging is observed in this population. Secondary analyses of 2 previously conducted dietary interventions including a 6-month modified ketogenic diet in 39 participants and an 8-week randomized comparison of intermittent and daily calorie restriction versus a weight-stable regimen in 36 participants demonstrated significant decreases in metabolomic age (mAge) following the ketogenic diet (p = 0.009) and intermittent calorie restriction (p = 0.04), whereas daily calorie reduction had no effect. These findings indicate that fasting-mimicking diets (FMDs) can reverse accelerated metabolomic aging in PwMS. ANN NEUROL 2025.

Research summary

Fasting-mimicking diets can reverse accelerated biological aging in people with multiple sclerosis. This paper is relevant as it explores dietary interventions that may address the underlying mechanisms of biological aging, rather than merely treating symptoms of a disease.
