Stay-Trim Tricks of the Trade: What Diet & Fitness Experts Eat

Secrets of a Toned Traveler

San Francisco-based triathlete, runner, and former fitness instructor Erica Dublin created seejanefly.com to help women stay fit on the road. "I fly several times a month, so I know how tough it is on your body and well-being," Dublin says.

Check out Dublin's bag of healthy tricks -- she takes packing light to a whole new level:

Quaker Lower Sugar Instant Oatmeal Buy a Dual Voltage Heating Coil beverage heater ($12.85, magellans.com) so you can prep a 110-calorie packet wherever there's an electrical outlet.

Gnu Foods Flavor & Fiber Bars "They taste like candy," Dublin says, but they have only 130 to 140 calories and almost a half day's worth of fiber.

Popchips These all-natural snacks are -- you guessed it -- popped, so they have less than half the fat of regular chips.

Steal this travel guru's secrets for a fit trip.

Don't pass the 'Bucks. "I stop at Starbucks on layovers; there's a store in practically every terminal," Dublin says. She relies on the Classic Salad or the Strawberry Banana Vivanno Smoothie, either of which has less than 300 calories.

Drink like a fish. Dehydration is a common traveling companion, especially now that you can't bring filled water bottles through security. Dublin sticks an empty one in her carry-on and fills it up once she gets to the gate.

Sweat in suite. Dublin packs Gaiam's reversible travel yoga mat ($29.98, gaiam.com), but she kicks hotel-room workouts up a notch with this total-body towel move. On a slick surface (try the bathroom floor), start in push-up position with a single towel under both feet. Keeping legs together and abs tight, slide feet toward your chest. Slide feet back to start; do 10 reps.
