Ketones Fill the Energy Gap as We Age

As we age, our capacity to metabolize glucose for energy goes down, while the same story is not true for ketones.

And that's why ketones can fill the energetic gap when we have problems with deriving energy from glucose. That's a major reason why women do better with ketosis after the age of 45, because energy is like this most precious currency of your body, and if you lack energy, all sorts of problems ensue.

So I recommend definitely to do the work to turn on that metabolic switch to be able to have this metabolic flexibility to switch between glucose and ketones as early in life as possible.
