Multiple sclerosis (MS) is an auto-immune condition that affects the brain and spinal cord. In MS, the coating that protects the nerves (myelin) is damaged, and this can lead to muscle wasting. The aim of this pilot study was to establish whether a low carbohydrate (‘ketogenic’) diet would lead to improvements in muscle mass in patients with MS. 27 MS patients were given instructions to follow a Mediterranean-style ketogenic diet that consisted of 20% total calories from protein, 40% of calories from carbohydrate and 40% of calories from fat, including 60ml of coconut oil per day. After four months on the diet, participants had gained muscle mass and lost fat. They also felt less hungry, and blood tests showed lower levels of inflammation and oxidation. The researchers concluded that a ketogenic diet has the potential to provide an additional therapy for patients with MS.
BACKGROUND
It was previously established that Multiple sclerosis (MS) generates energy alterations at the mitochondrial level related to the loss of muscle mass. Ketone bodies, mainly beta-hydroxybutyrate (BHB), re-establish this energy alteration causing satiety, changes in body composition and a decrease in hormone-dependant hunger, such as ghrelin. The aim of this study was to establish possible improvements in body composition and the level of oxidation in patients with MS, by means of the satiating effect of a ketogenic diet.
METHODS
A pilot study was carried out with 27 MS patients who were given a Mediterranean isocaloric and ketogenic diet for 4 months. Anthropometric measurements, as well as satiety and hunger perception (VAS scale), were taken. In addition, BHB and paraoxonase 1 (PON1), as an oxidation marker, were measured by spectrophotometric automated assays, and ghrelin was determined by an enzyme immunoassay in the serum. All measurements were taken before and after the intervention.
RESULTS
A significant increase in satiety perception at lunch and dinner and of BHB in the blood was obtained. Hunger perception decreased significantly at lunch and dinner with similar levels of ghrelin. In addition, an important increase in lean mass and PON1 was observed. To our knowledge, this is the first study addressing improvements in body composition, oxidation state and metabolism in MS patients, based on the satiating effect of a Mediterranean isocaloric diet.
CONCLUSION
A ketogenic diet increases lean mass and decreases inflammation and oxidation possibly as a consequence of an increase in satiety and decrease in hunger in MS patients.
