Estudio de enfoques dietéticos para tratar la fatiga relacionada con la esclerosis múltiple (Waves)

15 de septiembre de 2026 actualizado por: 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.

Descripción detallada

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.

Descripción del plan IPD

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

Marco de tiempo para compartir IPD

One year after publication of data.

Criterios de acceso compartido de 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.
