Dr. Cam is back and as always he was brilliant! Following on from our last episode, we got him back to answer some listener questions. We go real deep, so you might need a pen and paper. This time we explore the link between cravings and hormones, medical testing for food intolerances, shift work and circadian rhythms, puppy porn, how our dietary needs change as we age, reducing inflammation, veganism, weight training, tracking calories and macros (to count or not to count?), creating optimal online learning environments and lots more.
