A modified ketogenic eating regimen could also be price exploring for folks with mind tumors, based on a brand new examine revealed within the July 7, 2021, on-line problem of Neurology®, the medical journal of the American Academy of Neurology. The eating regimen is excessive in fats and low in carbohydrates.
The small examine discovered that the eating regimen was secure and possible for folks with mind tumors referred to as astrocytomas. The entire folks had accomplished radiation remedy and chemotherapy. The eating regimen led to modifications within the metabolism within the physique and the mind. The examine was not designed to find out whether or not the eating regimen might decelerate tumor progress or enhance survival.
“There aren’t plenty of efficient therapies for a majority of these mind tumors, and survival charges are low, so any new advances are very welcome,” mentioned examine creator Roy E. Strowd, MD, MS, MEd, of Wake Forest College of Drugs in Winston-Salem, N.C., and a Fellow of the American Academy of Neurology.
“These most cancers cells depend on glucose, or sugar, to divide and develop. For the reason that ketogenic eating regimen is low in sugar, the physique modifications what it makes use of for power — as a substitute of carbohydrates, it makes use of what are referred to as ketones. Regular mind cells can survive on ketones, however the principle is that most cancers cells can’t use ketones for power.”
The examine concerned 25 folks with astrocytomas. They adopted a kind of ketogenic eating regimen, the modified Atkins eating regimen with intermittent fasting, for eight weeks. The eating regimen consists of meals corresponding to bacon, eggs, heavy cream, butter, leafy inexperienced greens, and fish. Members met with a dietician at first of the examine after which each two weeks. 5 days per week they adopted the modified Atkins eating regimen, which mixed carbohydrate restriction with excessive quantities of fat. Two days per week they fasted, consuming as much as 20% of their really useful every day calorie quantity.
The principle purpose of the examine was to see if folks have been in a position to observe the eating regimen with no severe unwanted side effects. A complete of 21 folks accomplished the examine, and 48% adopted the eating regimen fully, based on their meals information. However urine assessments confirmed that 80% of the folks reached the extent the place their physique was primarily utilizing fat and protein for gas, relatively than carbohydrates.
The eating regimen was well-tolerated. Two folks had severe unwanted side effects through the examine — one was not associated to the eating regimen and one was presumably associated.
By the top of the examine, modifications within the metabolism within the physique and the mind have been seen. Hemoglobin A1c ranges, insulin ranges, and fats physique mass all decreased. Lean physique mass elevated. Specialised mind scans that detect modifications in mind metabolites confirmed a rise in concentrations of ketones and metabolic modifications within the tumor.
“In fact extra research are wanted to find out whether or not this eating regimen can stop the expansion of mind tumors and assist folks stay longer, however these outcomes present that the eating regimen might be secure for folks with mind tumors and efficiently produce modifications within the metabolism of the physique and the mind,” Strowd mentioned.
A limitation of the examine is that examine group members offered a excessive quantity of contact with individuals, which will not be possible in a bigger examine or in routine medical care.
