Why I Can’t Eat as Much as My Sister



Damn, as if losing weight wasn’t hard enough!

“When you begin to lose pounds, levels of the hormone leptin, which is produced by fat cells, begin to drop. That sends a message to the brain that the body’s “fat storage” is shrinking. The brain perceives starvation is on the way and, in response, sends out messages to conserve energy and preserve calories. So, metabolism drops.

And then other brain signals tell the body it’s “hungry,” and it sends out hormones to stimulate the appetite. The combination of lowered metabolism and stimulated appetite equals a “double whammy,” says Ryan. And that means the person who’s lost weight can’t consume as much food as the person who hasn’t lost weight.”
