Dr Gerber has posted Dr Phinney's talk AGAINST extended fasting given at Breckenridge, with his Slides, if anyone missed it last March.

There is also a link to ALL the Breckenridge talks. Dr Bikman's is very good about protein...which with all the back and forth about lean muscle loss on extended fasting, brings me back to some version of a PSMF.
