How Low-carb And Ketogenic Diets Boost Brain Health

Low-carb and ketogenic diets have many health benefits. For example, it is well known that they can cause weight loss and help fight diabetes. However, they are also beneficial for certain brain disorders. This article explores how low-carb and ketogenic diets affect the brain. Although there is a lot of overlap between low-carb and ketogenic diets, there are also a few important differences. Ketogenic diet: Carbs are limited to 50 grams or less per day. A major goal is to increase blood levels of ketones, molecules that can partly replace carbs as an energy source for the brain. Low-carb diet: Protein is usually not restricted. Ketones may or may not rise to high levels in the blood. On a ketogenic diet, the brain is mainly fueled by ketones. These are produced in the liver when carb intake is very low. On a standard low-carb diet, the brain will still be largely dependent on glucose, although it may burn more ketones than on a regular diet. Low-carb and ketogenic diets are similar in many ways. However, a ketogenic diets contains even fewer carbs, and will lead to a significant rise in blood levels of ketones. You may have heard that your brain needs 130 grams of carbs per day to Continue reading >>

    A bit over a year ago I started noticing difficulties with speaking, occasionally. I'd often completely blank on a word and stop talking midsentence, and kept using one tense of a word when I meant to use another. I wasn't having any issues thinking or writing, just talking. I was being screened for some other neurological issues at the time and came back with a clean bill of health, so I just assumed this was the dreaded "brain fog" that was a consequence of living too many years as a diabetic or just my age catching up with me (I'm 27).
    I've been on keto about six months, and it recently occurred to me that my tense misuse had virtually disappeared. Went off of keto for a few days last week, and just like magic, it was back.
    Just thought it was an interesting anecdote, and I'm curious if anyone else has noticed similar effects. I never really got the noticeable sustained energy boost or mental clarity that a lot of people feel on keto, but it's clearly still doing something for me.

    The cells in your brain quite literally work using different systems when you're in ketosis to such an extent that it's being actively researched for possible use in combating alzheimers, bpd and autism disorders.
    It's incredible just how many things it changes and how little we truly know about what exactly is going on.

  3. IllConceivedIdeas

    btw, just how far off did you go? Was it a lot of carbs or just a few more than your limit? Was a lot of sugar involved? You don't have to answer, but I'd be curious to know if you think there was any more to it than simply not being in ketosis.
