Hormone IRISIN Is Good For You
From conquering cravings to revving metabolism,
hormones are the key to zapping flab.
Here’s how to use them to your advantage.
A study of several years ago in the journal Nature announced the discovery of a way to make white fat – the kind we all know and hate – behave more like brown fat, a kind that actually burns calories.
The key is exposure to a newly discovered hormone dubbed IRISIN, which is produced during exercise. The hormone also appears to help reduce insulin resistance.
BALANCE IT OUT
Getting your sweat on is the number one way to ramp up irisin levels and produce more fat-burning brown fat.
In the Nature study, irisin lveles doubled after a 10-week stationary-bike training program that involved four or five 20- to-35-minute sessions a week.
Another, less obvious, tactic for increasing irisin is to adjust your thermostat. Literally.
Lower temperatures may make the white fat you have act like brown fat, shifting your metabolic rate enough to cause weight loss.
One study found that when people spent two hours in a 64F room and periodically dipped their feet into ice water, their brown fat burned 15 times more calories than it did at room temperature – enough to burn up to nine pounds a year. (Yeah, we’re going to skip the ice-water foot bath, too!)
