Background: Fasting -mimicking diets have shown promise in experimental autoimmune encephalitis and are currently being investigated among people with multiple sclerosis (MS). Ensuring adherence to diet changes is critical to determining the e fficacy of such interventions. Objective: Our primary aim was to evaluate the safety and feasibility of several fasting -mimicking diets and investigate whether various levels of clinical support improve diet adherence among people with MS. Secondarily, this study evaluated the impact of fasting -mimicking diets on weight and patient -reported outcomes (PROs). Methods: We conducted three pilot studies (two randomized controlled for 6 months; one randomized with transition to single arm) restricting either the amount or timing of calorie intake over 24 or 48 weeks. Interventions included calorie restriction (daily or intermittently) or time -restricted feeding. Adherence mea- sures varied across studies but were collected at study visits along with weight and PRO data. Results: A total of 90 participants enrolled; 70 completed the studies, with no serious adverse events reported. Overall adherence to the calorie restriction diets was poor. When participants were tasked with maintaining a diet in a pragmatic setting, neither previously completed intense clinical support and education, nor weekly electronic communication throughout the diet period appeared to improve diet adherence. Participants who were able to adhere to a calorie restriction diet predictably lost weight. In contrast to calorie restriction, ad- herence to a time -restricted feeding (TRF) diet was relatively good. No statistically signi ficant changes in PROs were observed in an intention -to -treat analysis. Conclusion: The role diet may play in clinical outcomes in MS remains unknown, as class I evidence is lacking. Diet adherence remains a primary barrier to the feasible conduct of large, randomized controlled diet trials. Strict adherence to a TRF dietary change may be more feasible than calorie restriction and should be considered in future fasting -mimicking diet trials.
