The pilot study, which investigated the effects of fat levels in blood on fatigue caused by multiple sclerosis, found that lowering total cholesterol also reduced exhaustion.The results, published recently in PLOS ONE highlight the impact that changes in diet could have on severe fatigue, which impacts the majority of those with multiple sclerosis.
Fatigue is a frequent and debilitating symptom for people with multiple sclerosis that affects quality of life and ability to work full time. Despite its prevalence and the severity of its impact, treatment options for fatigue are limited. The medications used to treat severe fatigue often come with unwanted side effects. “Fatigue in people with multiple sclerosis has been viewed as a complex and difficult clinical problem with contributions from disability, depression and inflammation. Our study implicates lipids and fat metabolism in fatigue,” said lead researcher Murali Ramanathan, PhD, professor in the University of Buffalo School of Pharmacy and Pharmaceutical Sciences. “This is a novel finding that may open doors to new approaches for treating fatigue.”
In previous studies, Terry Wahls, MD, clinical professor of internal medicine and neurology and creator of the Wahls Protocol diet, and her team of researchers at the University of Iowa, showed that a diet-based intervention accompanied by exercise, stress reduction and neuromuscular electrical stimulation (NMES) is effective at lowering fatigue. However, the physiological changes underlying the improvements were unknown.
Second hand smoking (breathing in air from smokers) can cause many of the same long-term diseases as direct smoking. There is no risk-free level of passive smoking; even brief exposure can be harmful to your health. If possible, stay away from smokers and avoid cigarette smoke where you can.
Leafy greens and fruitsThe researchers examined changes in body mass index (BMI), calories, total cholesterol, HDL, triglycerides, and low-density lipoprotein (LDL) – commonly known as bad cholesterol. Fatigue was measured on the Fatigue Severity Scale.
The small study followed 18 progressive multiple sclerosis patients over the course of a year who were placed on the Wahls diet, which is high in fruits and vegetables. The diet encourages the consumption of meat and fish as well as plant-based protein, plenty of leafy green vegetables, brightly coloured fruits like berries and fat from animal and plant sources, especially omega-3 fatty acids. Gluten, dairy and eggs are excluded. Participants also engaged in a home-based exercise program that included stretches and strength training, NMES to stimulate muscle contraction and movement, and meditation and self-massages for stress reduction. However, adherence to the diet was the main factor associated with reductions in fatigue.
However, according to the U.S. Centers for Disease Control and Prevention (CDC), these drugs are also indicated for anyone who has already had a heart attack or stroke or been diagnosed with peripheral arterial disease, has an LDL cholesterol of 190 mg/dL or higher, or is between the ages of 40 and 75 with an LDL level of 70 mg/dL or higher and diabetes or a high risk of developing heart disease or stroke.5.
“Higher levels of HDL had the greatest impact on fatigue,” said Ramanathan, “possibly because good cholesterol plays a critical role in muscle, stimulating glucose uptake and increasing respiration in cells to improve physical performance and muscle strength.”
One way to tell if you’re hydrated — your urine should be colorless or slightly yellow. If it’s not, you’re not getting enough water! Other signs include: Dry lips, dry mouth, and little urination.
