research summary

The research I referred to is as follows.
Dietary ketosis enhances memory in mild – PubMed Mobile
In this study, memory was compared between subjects with a low-carbohydrate diet and subjects with a high-carbohydrate diet.

research result

As a result, people who have been on a low-sugar diet for about 6 weeks have improved their memory.
The mechanism that improved memory is as follows.

  1. Continue low-sugar diet
  2. The liver breaks down fat to form ketone bodies
  3. Ketone body suppresses brain inflammation
  4. Increases memory

In other words, the anti-inflammatory action of ketone bodies may have an effect on the brain.

How to make practical use of this in your life

It is said that it takes about one month on average from the start of a low-sugar diet to the generation of ketone bodies.
So if you're on a low-sugar diet to improve your memory, keep it for a month.

This experiment was aimed at cognitive impairment.
For this reason, it has not been clarified in this experiment whether it is equally effective for healthy individuals.
However, it is true that the ketone body suppresses active oxygen and inflammation, so it seems worth trying.
