Train on an empty tank to boost your fuel efficiencyIt's an indisputable fact that to workout long and fast, you need to start out fully fueled. But during their prep for the Toronto Waterfront Marathon last fall, elite Canadian runners Reid Coolsaet and Eric Gillis adopted an unconventional approach: They performed some of their runs on empty tanks. It's the nutritional equivalent of training with a weighted vest; running on fumes forces your body to work harder and teaches it to burn carbs more efficiently when you workout with ample reserves.
Carbohydrates are your body's most readily available fuel source, but only a limited amount can be stored--enough to last for about 90 minutes of intense exercise--mostly in the muscles and liver. Researchers have found that exercising in a carb-depleted state helps the muscles adapt to burning more fat and boosts your body's capacity for stored carbohydrate by as much as 50 percent. Whether all this translates to better fitness is unclear, but for Coolsaet and Gillis, the evidence was

On a treatment plan that's not working? Here's what to look for when thinking about seeking out another expert's opinion.Sometimes a seemingly minor symptom or athletic injury sidelines you for longer than you'd like. Some injuries just need rest and icing, but others may land you in front of a doctor. Not every treatment plan requires a second opinion. But when you're undergoing a treatment plan--and anxious to be active again--it's important to know when to seek a different perspective.Read More »from 6 Signs You Need Another Doctor
How Fit Are You? 10 DIY Tests to Find Out
You're told that there's nothing to be done.
Almost all symptoms and injuries are treatable. So if a doctor tells you he can do nothing for you, make an appointment with another expert. That diagnosis most likely means "there's nothing more that that doctor can offer," says Michael Ross, M.D., medical director of The Rothman Institute Performance Lab in Cherry Hill, New Jersey. And while some conditions could certainly curtail your plans, you'll want to confirm a diagnosis like that with another physician before you quit your regular routine altogether.
How to Stay Active While
.Many of us would describe the ideal athlete's body as lean. But then someone who doesn't fit the description can lift heavier weights or finish a workout in less time than we can, leaving us questioning what "fit" really looks like.
Some doctors say people who are overweight face health issues, but some studies show that heavy people who exercise can be cardiovascularly healthy and may live longer than their sedentary but skinny peers.
We asked two experts to, ahem, weigh in. Glenn Gaesser, Ph.D., director of the Healthy Lifestyles Research Center at Arizona State University, says you can be fit and fat. Amy Weinstein, M.D., M.P.H., an assistant professor at Harvard Medical School who studies the impact of obesity and exercise on disease, disagrees. Here's why.

Nutritious, flavorful ingredients lift the postrun smoothie to healthier heightsAfter a long or hard workout, the last thing you may feel like doing is eating a big meal, particularly if your workout left you queasy. But you need to refuel, preferably within 30 minutes, so you can recover. That doesn't mean you have to cook up a heavy omelet or big bowl of oatmeal. A quick, tasty smoothie will kick-start recovery. "Smoothies are a great way for runners to meet nutrient needs," says sports nutritionist Cassie Dimmick, R.D., "especially when it's necessary to quickly consume a mix of carbs and protein for muscle repair."Read More »from 4 Post-Workout Summer Smoothies to Try

Splurge: GRASS-FED BEEF
In a 2006 study in the Asia Pacific Journal of Clinical Nutrition, researchers tested various cuts of beef from grass--and grain--fed cattle and concluded the former have higher levels of two types of healthy fat-omega-3s (which reduce inflammation) and conjugated linoleic acid (or CLA), which some studies have linked to body-fat loss.

Travel Smart: Know Your Needs
Lots of athletes think they have to stick to high-carb, low-fat, low-fiber foods before a workout. But exactly what you eat is less important than knowing what you can eat. "You've got to train the gut," says Jackie Dikos, R. D., a nutritionist and competitive runner. The key is to test out different pre-workout meals, take note of how your system handles them, and remember what works (and doesn't) for you. If you know your fave is chicken-vegetable stir-fry with white rice, you can search out Chinese restaurants. If you must have coffee before morning workout, you can make sure your hotel offers in-room coffeemakers (or an on-site Dunkin' Donuts).

Control the candy dish. In a study by Brian Wansink, Ph.D., author of Mindless Eating, secretaries ate an average of 2.2 more candies when they were in a clear bowl and 1.8 more candies when the bowl was on their desk as opposed to two meters away. The lesson to be learned: If there is a candy dish in your office, make it a covered, opaque dish, and keep it off your desk.
Don't multitask--especially if eating is one of the tasks. "The mind cannot pay attention to too many things at once, so if you're doing more than one thing, plus eating, the food doesn't really register," says Evelyn Tribole, M.S., R.D., a Newport Beach, California-based dietitian and
