Podcast: Living Well with Multiple Sclerosis by Overcoming MS

Episode Overview

This episode dives into the impact of lifestyle choices on Multiple Sclerosis (MS), guided by the expertise of Dr. Aaron Boster. Focusing on his “4 for 4” approach, Dr. Boster outlines four critical pillars he encourages people with MS to adopt: not smoking, exercising regularly, maintaining a healthy diet (with a focus on vitamin D), and taking MS medication. The conversation also explores additional elements of holistic health, such as stress reduction and family support, and practical advice for integrating these habits into daily life.

Key Discussion Points & Insights

1. The “4 for 4” Approach to MS Management

Pillar 1: Not Smoking

• Smoking’s Role in MS: Dr. Boster stresses that smoking is one of the most damaging choices for people with MS, accelerating disease progression significantly.
  • “Smoking is probably the best way to make you get worse fast with multiple sclerosis.” (A, 03:13)
• Broader Cardiovascular Risk Factors: Not just smoking, but managing co-occurring risks like hypertension and high cholesterol are crucial.
  • “Uncontrolled diabetes or high blood pressure actually makes people with MS get worse faster.” (A, 03:54)

Pillar 2: Regular Exercise

• Exercise Benefits: Regular physical activity is linked to better long-term outcomes, reduced fatigue, better mental health, and improved cognition.

  • Dr. Boster uses a striking analogy of “Clone A” and “Clone B” to show how conditioning can impact recovery from MS relapses (A, 08:17–10:45).
  • “Exercise has been shown to increase sleep quality, to improve energy levels, to decrease pathologic fatigue, to improve cognition… and it’s not a medicine, it’s free.” (A, 11:04)

• Exercise Type: The best exercise is the one that the patient will continue. Aquatic exercise is highlighted as especially favorable for MS symptoms.

  • “If you are passionate about yoga... do a lot of yoga. If you love being in the gym, that’s what I want you to do.” (A, 11:51)
  • “Water is really special because in the water you weigh less… if you get overheated, the water pulls the heat off your body.” (A, 12:51)

• Incremental Approach: Avoid the “high school mentality” of pushing too hard; instead, build up slowly and use the following day as a measure of success.

  • “If you could exercise and the next day was a normal day for you, then I’d submit you didn’t overdo it.” (A, 14:43)

Pillar 3: Diet and Vitamin D

• Vitamin D: Supplementation is important due to clear associations between low vitamin D and increased MS risk/progression, particularly for those living far from the equator.

  • “Low levels of vitamin D in specific do have an impact on the course of the disease.” (A, 18:31)

• Healthy Diet: Avoid highly processed and sugar-laden foods; eat “real food” with minimal ingredients.

  • “What I typically will tell people is if you look at the ingredients and you can’t pronounce the words or you don’t know what the words are, that’s not food.” (A, 22:11)

• OMS Alignment: The recommended whole-food, low-saturated-fat diet aligns with the OMS (Overcoming MS) dietary approach.

Pillar 4: MS Medication

• Complementary, Not Alternative: Lifestyle changes and medication work synergistically, not as substitutes.
  • “It’s not like a piece of pie where you have this one or that one. We can do it all at the same time... I want to use every modality that’s available to help you achieve your goal.” (A, 24:26)

2. Additional Holistic Considerations

Stress Reduction & Mindfulness

• Mindfulness: While not originally part of Dr. Boster’s four pillars, he fully endorses mindfulness and stress management.
  • “My patients that are able to work to reduce the stress in their life... they do better. And so why would we not want to bring that to the table?” (A, 26:31)
• Practicality Over "Remove Stress": Dr. Boster objects to unrealistic advice:
  • “I hate it when doctors tell people to remove stress… I don’t know how to remove stress.” (A, 25:38)

Family & Social Circle Involvement

• Village Model: Dr. Boster advocates rallying a “village” to support the person with MS.
  • “You don’t get to have MS by yourself... Rallying the villagers to support you in a healthy manner is simply brilliant.” (A, 27:44)
• Family Prevention: Family members of people with MS have a slightly increased risk and should also adopt healthy habits, like avoiding tobacco and supplementing vitamin D. (A, 28:34)
