I am like Ruth, visual learner. I have given up on podcasts for learning anything.
p.s. the things I particularly like about Dr. Attia, are that he is a doctor, and that he advocates it is unlikely that any one program of eating is going to work for everyone, and that it is going to take n=1 experimentation. I also like that he doesn't try to sell you things (well except for the superstarch he uses for performance athletics-which absolutely does not apply to me!)
