Let’s round out the week with a little levity, shall we? Robert Lustig sure does make the rounds, and last night he was the guest on The Colbert Report to report his new book, Fat Chance.
There’s really not much new here. It’s entertaining, but most of all, it warms my heart to see Lustig make such inroads into popular culture. Something good may come of this…
Let’s start with a few givens (i.e. things that are well documented and known):
- Cortisol is the “stress” hormone. It is good in small amounts (getting you up in the morning, running away from lions) and bad in the chronic long term (immune suppression, abdominal “beer belly” obesity).
- Serotonin is the regulator of the six F’s: Fight, Flight, Food, Falling asleep, Feeling good, and… Sex. Too much is bad too little is bad. The same story as cortisol.
- Serotonin is involved in regulating cortisol secretion by the 5-HT(2a/2c) receptors (more serotonin, less cortisol)
