Approches diététiques pour traiter l'étude de la fatigue liée à la sclérose en plaques (Waves)

15 septembre 2026 mis à jour par: Terry L. Wahls

The purpose of this study is to compare the effect of the Swank Diet (low saturated fat) and the Wahls Elimination Diet (modified paleo) on fatigue levels in individuals with relapsing-remitting multiple sclerosis who have documented fatigue. Participants will follow their usual diet for 12 weeks and then be randomly assigned to follow one of the two diets for 24 weeks.

Description détaillée

The purpose of this study is to compare the effect of the Swank Diet (low saturated fat) and the Wahls Elimination Diet (modified paleo) on fatigue levels in individuals with relapsing-remitting multiple sclerosis who have documented fatigue. Participants will follow their usual diet for 12 weeks and then be randomly assigned to follow one of the two diets for 24 weeks. Individuals will continue with their current treatments in addition to following the study diet.

The study requires four visits to the University of Iowa Hospitals and Clinics in Iowa City, Iowa. Visits will be 12 weeks apart. Study activities include fasting blood draws, weighed food records, motor and cognitive testing, physical activity assessment, questionnaires, and daily diet checklists while following the study diet. Some reimbursement available.

Armes et Interventions

Groupe de participants / Bras
Intervention / Traitement
Expérimental: Swank Diet

Individuals randomized to this arm will follow a low saturated fat diet starting at week 12.

A Registered Dietitian Nutritionist (RDN) skilled in motivational interviewing will provide nutrition counseling to study participants to assist them in following the Swank Diet at home. An in-person counseling session will occur at study visits 2 and 3. Five telephone counseling calls will occur between visits 2 and 3. The study participant may contact the RDN with questions at any time during the intervention.

Expérimental: Wahls Elimination Diet

Individuals randomized to this arm will follow a modified paleolithic diet that eliminates all grains, dairy, eggs, legumes, and nightshade vegetables/spices starting at week 12.

A Registered Dietitian Nutritionist (RDN) skilled in motivational interviewing will provide nutrition counseling using to study participants to assist them in following the Wahls Elimination Diet at home. An in-person counseling session will occur at study visits 2 and 3. Five telephone counseling calls will occur between visits 2 and 3. The study participant may contact the RDN with questions at any time during the intervention.

Description du régime IPD

Scientists may request data for a PROSPERO registered meta-analysis that has been published in a peer reviewed journal.

Délai de partage IPD

One year after publication of data.

Critères d'accès au partage IPD

Scientists who have a PROSPERO registered meta-analysis with a protocol that has been published in a peer reviewed journal may request data for that meta-analysis. The scientist will use their academic email to reach out to the PI with the protocol manuscript describing the data that is requested, their address, phone number and contact details. Upon review of the documents, and the request, the PI will determine if the request meets guidelines. If the request is deemed appropriate the PI will initiate an outgoing material data use agreement with the Division of Sponsored Programs at the University of Iowa who will contact the requesting scientists to sign the contract.
