Efficacy of Diet on Quality of Life in Multiple Sclerosis

Running, not enrolling · Not applicable

Conditions studied: Multiple Sclerosis, Relapsing-Remitting

In brief

The overarching goal of this project is to critically evaluate the efficacy of incorporating dietary guidance within multiple sclerosis (MS) care for improving long-term quality of life (QoL) compared to usual care. The primary objective of this study is to evaluate the effect of two dietary interventions (time restricted olive oil based (TROO) ketogenic and modified Paleolithic elimination) on MS QoL compared to usual care control (Dietary Guidelines for America), and the secondary objectives and the long-term effects on, motor function, low-contrast vision sensitivity, fatigue, mood, and disease activity assessed by brain imaging.
