Brief summary
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.
Detailed description
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.
Interventions
BEHAVIORALSwank Diet
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.
BEHAVIORALWahls Elimination Diet
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in participant perceived fatigue severity | 12-24 weeks | Participant questionnaire asking about fatigue: Fatigue Severity Scale score - a 9-questions scale ranging from 1 (complete disagreement with the question) to 7 (complete agreement with the questions) |
| Change in the impact of fatigue on daily life | 12-24 weeks | Modified Fatigue Impact Scale score: Participant questionnaire asking about impact of fatigue impact daily life: Modified Fatigue Impact Scale score. This instrument provides an assessment of the effects of fatigue in terms of physical, cognitive, and psychosocial functioning. The MFIS consists of 21 items. Scoring is based upon a sum of the responses. Total score ranges from 0 to 84. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in fine motor function | 12-24 weeks | Pegboard test |
| Change in nutrient intake based on the recommended daily allowance (RDA) | 12-24 weeks | Nutrient intake calculated from 3-day weighed food records and Food Frequency Questionnaire and Participant blood measurements of insulin, glucose, hemoglobin A1C, Vitamin K, homocysteine, lipids, fatty acid profile and vitamin D. |
| Change in cognitive function | 12-24 weeks | Symbol Digit Modalities Test - oral. An oral test of sequencing symbols. •Participant substitutes a number for meaningless geometric shapes based on a key that assigns a specific number to each shape. Scoring is based on the number of correct substitutions. |
| Change in steps per day | 12-24 weeks | Measured by accelerometer |
| Change in participant walk speed | 12-24 weeks | 6 Minute Walk Test |
| Change in participant Quality of Life (QoL) - Mental Health | 12-24 weeks | Multiple Sclerosis Quality of Life Questionnaire A series of questions about quality of life and social functioning. Score 0 to 100. |
| Change in total sleep time | 12-24 weeks | Total sleep time is measured in hours and minutes and tracked by accelerometer worn by participants throughout the study |
| Change in perceived anxiety | 12-24 weeks | Perceived anxiety is measured by the Hospital Anxiety and Depression Scale (HADS), a 14 question scale ranging from 0-3 with zero being being low or no occurrence and 3 being high occurrence. |
| Change in perceived depression | 12-24 weeks | Perceived depression is measured by the Hospital Anxiety and Depression Scale (HADS), a 14 question scale ranging from 0-3 with zero being being low or no occurrence and 3 being high occurrence. |
| Change in participant Quality of Life (QoL) - General Health | 12-24 weeks | Multiple Sclerosis 54 Quality of Life Questionnaire. A series of questions about quality of life and social functioning. Score 0 to 100. |
