Some things are better fast: cars, roller coasters — and your metabolism.

The Fast Metabolism Diet, a new book due out next month by star nutritionist Haylie Pomroy, aims to help accelerate your body’s calorie-burning engine. Pomroy, a wellness consultant for 19 years who has advised Reese Witherspoon, Robert Downey Jr. and Jennifer Lopez, says, “I wanted to create a plan to enhance the rate of burn, relying on food as medicine.” Her 28-day plan, described as “cross-training for your metabolism,” has three phases each week: Monday and Tuesday, you load up on carbs and fruit; fuel with proteins and vegetables the next two days; and Friday through Sunday, eat all of the above plus healthy fats. The cycle repeats over 28 days, during which you can lose up to 20 pounds. Vroom, vroom!

Pack And Go

Pomroy’s best travel tips for keeping your metabolism moving as fast as you are.

Always drink half of your body weight in ounces, but on travel days, drink an extra eight ounces per hour of flight time to avoid dehydration.

Have a stash of lean, high-protein foods, such as turkey jerky and almonds, available as between-meal snacks, and eat every three to four hours.

Be Fruity
Add a piece of whole fruit to each meal; it can help lower stress hormones.

Lay off of caffeinated beverages, which can stress your adrenal glands while you’re traveling.

Rise and Eat
On the day of travel, make sure you eat within 30 minutes of waking — no matter what time your flight.
