Healthy Sports Drinks for Weight Loss

Compared to a commercial sports drink, coconut water—a natural source of electrolytes—was equally as effective in hydrating participants after an intense workout, a 2012 study in the Journal of the International Society of Sports Nutrition found. So why choose the coconut water over a traditional sports drink? For one, coconut water is low on the glycemic index, so it won't dramatically affect your blood sugar, while fluid-replacement beverages like Powerade are sweetened with high-fructose corn syrup, a high-glycemic-index sweetener that can spike blood sugar levels and promote body-fat storage. Second, a 2010 study in the Journal of Cell & Tissue Research found that coconut water helped reduce blood pressure and cholesterol in rats, suggesting that the drink may also promote heart health.

During a 1-hour time trial, cyclists who took a caffeine supplement were able to ride about a mile farther than those who took a placebo, a 2008 study published in the International Journal of Sports Physiology & Performance found. What's more, other scientific research has linked caffeine consumption with increased endurance and reaction times. The problem is, most caffeine-enhanced energy drinks are loaded with added sugars (what's the point of an exercise-boosting drink that makes you fat?). A much more waistline-friendly way to reap the benefits of caffeine: black coffee. It's sugar-free, packed with antioxidants and free of calories.

If you typically head to the gym in the evening and don't like the idea of catching a buzz after dark, consider sipping beet juice instead. It's rich in nitrate, which dilates blood vessels and increases blood flow and has been shown to have positive cardiovascular effects during exercise and lead to increased endurance.

Green tea is another smart source of energy-enhancing caffeine. Like coffee, it's packed with antioxidants, and a 2011 research review published in the British Journal of Nutrition found that the herbal drink may also promote weight loss. A great way to get green tea on the go: EBoost. Unlike most green-tea based energy beverages, it's sweetened with natural, zero-calorie Stevia, and it boasts an impressive antioxidant profile. Compare it to conventional bottled green teas—some of which pack as much sugar as three whole Kit Kat bars!—and the winner is clear.

While taking your workout outside on a warm, beautiful day can seem appealing, hot weather sweat sessions can lead to dehydration, which can strain the heart and make it difficult for muscles to work efficiently. Fuel up with V8 an hour before your workout to ward off dehydration side effects like cramping and light-headedness. The drink has just the right amount of sodium and is great source of potassium, two electrolytes lost through sweat during intense exercise. And as an added bonus, each cup counts as two servings of vegetables.

Drinking a combination of carbohydrates and protein after a hard workout can help restore your energy and aid in building lean, metabolism-boosting muscle, but it turns out that you don't need a fancy recovery beverage to reap these benefits. After participating in a vigorous cycling session, cyclists who drank chocolate milk were able to ride 51 percent longer in a subsequent workout than those who drank a standard recovery beverage, a 2009 article in Applied Physiology, Nutrition, and Metabolism found. Plus, chocolate milk is cheaper (and tastier) than anything you'll find in a sports nutrition store.6254a4d1642c605c54bf1cab17d50f1e

You may feel trendy with a bottle of vitamin-enhanced water in your hand, but that brightly-hued liquid probably isn't improving your health. Most vitamin-infused H20 is just colored sugar water with some vitamins tossed in—bad news when you consider that Americans take in about 355 calories of added sugar every day. If you want vitamins, get them from vitamin supplements or, better yet, from whole foods (wild salmon, for example, is loaded with energy-boosting vitamin B-12). And if you want water, get it from, well, water. Nature's beverage is calorie-free, cost-free and, unless you're an elite athlete who does high-intensity exercise for more than an hour at a time, it'll take care of all your workout hydration needs.
