Ketosis FAQs / How does our body use ketones?

Comments Off on Ketosis FAQs / How does our body use ketones? | May 13, 2013

In the event of low blood glucose, as it is the case in ketogenic diets, most other tissues have additional energy sources besides ketone bodies (such as fatty acids), but the brain has an obligatory requirement for some glucose.

After the diet has been changed to lower blood glucose for 3 days, the brain gets 25% of its energy from ketone bodies. After about 4 days, this goes up to 70% (during the initial stages the brain does not burn ketones, since they are an important substrate for lipid synthesis in the brain). Furthermore, ketones produced from omega-3 fatty acids may reduce cognitive deterioration in old age.
