Books (edited to include reasons)

Perfect Health Diet (dense, persuasive, hundreds of citations)

How to Fail at Almost Everything And Still Win Big (its very rational seeming for a self help book, his systems approach is interesting, the book includes some counter arguments to common memes (like questioning the direction of causality in the whole passion/success thing), he mentions other research and memes that will sound familiar to anyone who reads lukeprog self help posts, he assumes he and the readers are moist robots, it's self skeptical and cautious about naively assuming he knows why something seems to work)

Podcasts:

Zen Habits, Tim Ferriss Experiment, Conversations From the Pale Blue Dot

You might also find it worthwhile to search youtube for Ted Talks, lectures, interviews etc, and rip out their audio. If there is a popular book there is often a shorter free video of the author explaining and summarizing its basic gist.
