Don't skimp on sleep

"Get six to eight hours of sleep a night. Without it, the appetite hormone ghrelin increases, which could result in weight gain. And schedule at least two three-minute breaks during the day to practice deep-breathing exercises. It will reduce the stress hormone cortisol, whichbuilds fat around your mid-section."
