Here are three to start sipping.
Call it nature’s perfect energy drink: Research shows drinking two to three cups ofÂ coffeeÂ before a workout can spur you to work out longer and harder than you would if you hit the gym caffeine-freeâ€”and that means youÂ torch more calories. One study in theÂ Journal of Sports Medicine and Physical FitnessÂ found that exercisers could do almost 20 percent more reps on a leg press machine when they fueled with java. But remember: Always drink it black (or add a little no-calorie stevia extract), since loading up on cream and sugar is the fastest way to undo the benefits of your coffee-fueled extended workout. (Bonus: There are tons of otherÂ reasons your body loves coffee.)
Swap out the squeeze of lemon for a handful of ice: Cold drinks prompt your body to expend more energy to maintain its preferred 98.6-degree temperature. This means downing three 24-ounce servings of ice water in a day can help your body burn up to 100 extra calories, says Mitzi Dulan, R.D., nutritionist for the Kansas City Royals and author of The Pinterest Diet. Do it every day and you could lose up to 10 pounds over the course of a year.
Not only isÂ green teaÂ gloriously calorie free, it can also help spur fat burn andÂ weight loss. In one study, participants who drank four cups ofÂ green teaÂ daily for two months lost six more pounds than those who drank just plain water, according to research published in theÂ Journal of the American College of Nutrition. Another 2013 analysis from theÂ European Journal of NutritionÂ found that regularÂ green tea drinkers weigh less, have smaller waists, and reap theseÂ green tea health benefits. (Scientists speculate green tea’s combo of catechin antioxidants and caffeine are behind the effect.) Choose fresh, hot brewed tea with nothing addedâ€”store-bought bottled brews tend to have fewer antioxidants and can be loaded with excess sugar. Stay away from unregulatedÂ green teaÂ supplements, too: They’re a frequent cause of liver damage and may contain unsafe doses of compounds isolated from tea.
