Good for Dave Feldman, he's gathered enough data and questions along with some other studies, where the unique situation with Lean Mass Hyper Responders study has now been funded. I know many on this forum will be very interested in the eventual outcome, and while the initial outcome may not answer everything (no study ever does), the conclusion will hopefully spur more investigation. Good presentation and background information from Dave and others:

Kudos to Janet for sending me the link to the 2021 Low Carb Down Under that enabled me to locate this presentation.
