nehopelon/iStock(NEW YORK) — The foods we should be eating — fruits, vegetables, lean protein, healthy fats — are well-known, but many don't realize that the timing of when you eat affects how you feel and how healthy you are too.
The idea that timing matters when it comes to food is the focus of a new book, What to Eat When, by Dr. Michael Roizen, chief wellness officer at the Cleveland Clinic, and Dr. Michael Crupain, chief of the medical unit at The Dr. Oz Show.
"Your circadian rhythm changes your metabolism throughout the day and it gets your body ready to eat the right thing at the right time," Crupian told ABC News' Good Morning America. "The job of your circadian rhythm is to get your body to do the right thing at the right time, so you want to align what you eat with when you eat it."
"Then you're really hacking your metabolism get better health, sleep better, to have more energy and to even help you lose more weight," he added.
Crupain and Rozin shared with GMA what they learned while writing the book, from how long to wait to eat between meals to why they like to eat dinner for breakfast. Watch the video below to learn more:
