On Dietdoctor.com he has posted a BBC doumentary called The Truth About Carbs. It can be seen in its entirety as a non-member. Nothing really "new" in it but reinforcement is always good.
I am somewhat confused. Can someone clarify the difference between the two (aside from number of carbs ingested)? I know that we can both gain and lose weight doing both; is the main advantage to keto the mental clarity and/or increased energy expenditure?
