Must add a newly found favorite. Have enjoyed TheIHMC videoed lectures on YouTube for many years, but now IHMC has a podcast callled STEM-talk. 31 talks so far, about a third are food, cancer, fasting related, while others are on science, cosmos, physics, etc.

Some well known speakers from the LC world are Dr Colin Champ, Dr Dom D'Agostino, Mark Mattson, ARt DeVany, Robb Wolf. Smart interviewers.
