Why We Eat: Cravings

HiRes 2Last week I picked up the theme of hunger with an intention to visit all the angles of the instinct – the physiology behind it first – but also the outer reaches of hunger’s emotional and social sway. The fact is, I can’t think of an instinct (other than sex) that influences our evolution more or perhaps a more complex motivation. It’s one of those areas in which you can’t always separate biology from emotion. (The more you learn about the human animal, I think, the more apparent the melding of these two fields/forces becomes.) Enter cravings. Beyond the general experience of hunger (Feed me now!) are the urges toward particular foods (Need THIS now!). What exactly goes on here?

commutingBetween gas, car maintenance, bus fare, and train tickets, commuting can get expensive. Driving a mile in the US costs around $0.55, according to the IRS, and some estimates (PDF) even peg this country’s working poor as spending close to 10% of their income on commuting. Financial experts suggest that a one way commute of 20 miles (which is roughly average) will cost you almost $50,000 every ten years. If you’re one of the 600,000 “mega-commuters” who travel at least 90 minutes each direction in the US, your costs skyrocket.

Dear Mark: Dealing with Undersleeping, and the Nutritional Value of Yeast

yawnFor today’s edition of Dear Mark, we’ve got two questions. First up is a big one: how do you deal with the inevitable bout of acute sleep loss? Are there pills to take, exercises to do or avoid, foods to eat or not? Or are we completely helpless in the face of undersleeping? And second, I discuss the importance – or not – of yeast in the diet. Are we missing out on an integral part of the human diet by avoiding the yeast found in bread?

Let’s find out:

Weekend Link Love – Edition 310

weekend link love2I did a few podcasts recently. First, I talked about the basics of Primal living on the Low Carb Paleo Show. I also chatted with Sam Feltham of Smash the Fat and Chris Martenson of the Peak Prosperity podcast about the primacy of diet in determining our health and genetic destiny.

Long term (5 year) ketosis has no negative effect on bone density and body composition in adults with GLUT-1 deficiency.

Those fMRI studies should be taken with a grain of salt. Active neurons don’t always show increased blood flow.
