Eat at least 3 times day.
And more if you’re hungry.
“Don’t let yourself get too hungry; otherwise you may end up eating more than you need,” Feldman says. “If you feel yourself getting hungry, don’t try to deny it. If you’re not eating enough calories, you could slow down your basal metabolic rate, forcing your body to go into conservation mode.”
She notes that the body’s ability to slow its metabolism was an evolutionary advantage: In prehistoric times when food wasn’t as readily available, there was a benefit to having your metabolism slow down, so you could last longer without food. Now, however, a slower metabolism is not an advantage for most of us. Eat frequently and keep your metabolism in tip-top shape.
