Yesterday, I was tagged in a post on Instagram (follow me there if you aren’t already, if you want) about a weight loss before and after photo regarding keto supplements.

Exogenous ketones have some very diverse marketing. Some companies just say “this is a source of ketones” and others say that they will “help melt body fat”, “give you limitless energy” and other extreme stuff like that.

I have been meaning to make this video for a while but this prompted me along.

What does the science actually say about exogenous ketones (ketone supplements).

Are ketone supplements actually useful for weight loss? Let’s take a look.
