Digital lifestyle program produced durable diet and sleep gains for people with MS, study finds

Researchers in the Netherlands evaluated a digital multidomain lifestyle program for people with multiple sclerosis (MS). The intervention promoted a Mediterranean-style diet, regular physical activity, improved sleep, and stress management through online coaching and expert guidance. The study reported outcomes up to two years after starting the program.

• Enrollment: 659 adults with MS in the LIMS study (NCT05402501) recruited between 2021 and 2022.
• Sequence: three-month observation, three-month intensive online program, then a 21-month maintenance period.

• Publication: results published in Neurology.

Most measurable improvements occurred during the three-month intensive program. Over the 21-month maintenance period, several gains weakened but remained above pre-program levels:

• Diet: adherence to a Mediterranean-style diet rose substantially during the intensive phase and, despite some decline, stayed better than baseline at two years.

• Physical outcomes: the physical impact of MS on daily life improved during the intensive phase but decreased during maintenance and was no longer significant at two years. About one-third of participants met Dutch physical activity recommendations at the start, and that proportion did not change significantly.
• Body composition: body mass index and waist circumference decreased during the intensive phase and remained significantly lower at two years compared with baseline.
• Cognitive complaints: little change was observed in self-reported cognitive complaints.

• Association, not proof: the study had no control group, so it cannot establish that the program caused the observed improvements.
• Magnitude of effects: changes were modest overall. Researchers suggested lifestyle programs are unlikely to produce large symptom shifts on their own but could complement medical treatments.

What this means for people with MS and clinicians

• Digital delivery can reach many patients and produced measurable short-term improvements in diet, sleep, stress, and psychological well-being.

• Incorporating structured coaching for diet and sleep appears feasible and produced the clearest lasting behavioral changes in this study.
• Because the study lacked a control group, clinicians should view these findings as encouraging but preliminary when considering digital lifestyle programs for long-term MS management.

• Patients interested in lifestyle programs should ask whether an intervention provides ongoing maintenance support, structured coaching, and measurable targets for physical activity.
• Clinicians can consider recommending evidence-supported dietary patterns and sleep strategies as adjuncts to medical therapy while monitoring functional outcomes over time.

A large Dutch trial found that a three-month intensive online lifestyle program led to improvements across diet, sleep, psychological measures, and some physical metrics in people with MS. Many gains lessened during a 21-month maintenance phase but remained above baseline for several outcomes. The lack of a control group limits causal claims, and physical activity proved the hardest behavior to change long-term.
