Stress and Food Consumption
033 🐣Evolution has allowed the development of efficient use of the body’s chemical messengers, and CRH is no exception. It is also used in parts of the brain to regulate other features of the Stress-Response. It helps to turn on the Sympathetic Nervous System (SNS), and it plays a role in increasing vigilance and arousal during Stress. It also suppresses appetite. (Location 1225)
==Glucocorticoidss don’t just stimulate appetite—they stimulate it preferentially for foods that are starchy, sugary, or full of fat== (Location 1235)
==CRH is the fastest wave of the adrenal cascade, Glucocorticoidss the slowest.== (Location 1240)
If the stressor ends after, say, ten minutes, there will cumulatively be perhaps a twelve-minute burst of CRH exposure (ten minutes during the stressor, plus the seconds it takes to clear the CRH afterward) and a two-hour burst of exposure to glucocorticoids (the roughly eight minutes of secretion during the stressor plus the much longer time to clear the glucocorticoids). (Location 1254)
Frequent bursts of CRH release throughout the day. As a result of the slow speed at which glucocorticoids are cleared from the circulation, elevated glucocorticoid levels are close to nonstop. Guess who’s going to be scarfing up Krispy Kremes all day at work? (Location 1266)
glucocorticoid hypersecreters are the ones most likely to be hyperphagic after stress.
Moreover, when given an array of foods to choose from during the post-stress period, they also atypically crave sweets. (Location 1276)
==during stress, people who are normally restrained eaters are more likely than others to become hyperphagic.== (Location 1285)
if it’s food intake that you’re normally regimented about, out come the fudge brownies. (Location 1290)
