While it's true that fruit-based beverages are loaded with fructose, a type of sugar associated with the development of belly fat, tomato juice is one variety that actually deserves a place in your cup—despite being rich in the sugar. Why? The study found that women who drank nine ounces of this beverage daily saw a significant decrease in their body fat, waist circumference and weight after just two months—without making any other changes to their diet or exercise routines. Sipping the juice also lowered participants' cholesterol levels and increased the amount of the antioxidant, lycopene, in their system. Besides giving tomatoes their bright red color, lycopene has been shown to boost immunity, lower the risk of prostate cancer and protect against heart disease.

Although the effects of the drink were only tested in women, slugging back the waist-whittling elixir will likely be beneficial for men, too. We know that not everyone finds plain ol' tomato juice very appetizing, but thinking of it as a fat frying virgin Bloody Mary may help it go down a bit easier.

BEST MILK

Organic, 100% Grass Fed Milk

Organically raised cows are not subject to the same hormones and antibiotics that conventional cows are; no antibiotics for them means no antibiotics for you. Grass fed cows have been shown to have higher levels of omega-3 fatty acids (good) and two to five times more CLA (conjugated linoleic acid) than their corn and grain fed counterparts. CLA contains a group of chemicals which provides a wide variety of health benefits, including immune and inflammatory system support, improved bone mass, improved blood sugar regulation, reduced body fat, reduced risk of heart attack, and maintenance of lean body mass.6254a4d1642c605c54bf1cab17d50f1e

BEST JUICE ALTERNATIVE

Detox Water

It's no secret that chugging plain H2O can be less than stimulating, but there are fun ways to make this healthy habit less of a chore. Certain fruits have detoxifying properties in their flesh and peels; slice them whole into your water to reap the benefits and hit your water intake quota with an infusion of flavor. For delicious ways to drink up and de-puff, check out our list of 14 Detox Waters that Banish Bloat.

BEST TEA

Oolong

There are so many teas that aid weight loss, it's truly hard to pick just one. But oolong may just be one of the best brews to give you that long, lean look you crave. Oolong, a Chinese name for "black dragon," is a light, floral tea that, like green tea, is also packed with catechins, which help to promote weight loss by boosting your body's ability to metabolise lipids (fat). A study in the Chinese Journal of Integrative Medicine found that participants who regularly sipped oolong tea lost six pounds over the course of the six-week time period. That's a pound a week!

BEST SMOOTHIE

Mango Lassi

Lassi is a popular drink from India and Pakistan, made from fermented yogurt. In Ayurvedic medicine, lassi "cools" the digestive system, aiding gut function. From a modern medical perspective, lassi is a fermented food that contains many healthy bacteria, or probiotics, which decrease bloating and reduce inflammation—two key contributors to weight loss. While lassi can be made with any number of fruits, mango lassi is one of the easiest and most popular drinks in India: Simply combine in a blender one cup of plain Greek yogurt, 1 tbsp of sugar, ½ cup frozen mango chunks, and enough water to blend. Pair it with these exclusive 14 Ways to Lose Your Belly in 14 Days for best results.

BEST PRE-WORKOUT DRINK

Black Coffee

While H20 is the best bet for your body during workouts, a cup of black coffee should be your go-to pre-workout beverage. 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 longer and harder you can work out, the more calories and fat you're apt to burn. 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.

BEST POST-WORKOUT DRINK

Chocolate Milk

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.

BEST BEER

Sam Adams Light

In a recent Eat This, Not That! taste test, we rounded up all of the light beers we could find that ranked among the top 20 most purchased beers in America. we managed to track down all but Busch Light and Michelob Ultra and filled in the rest of the list with light beers we felt would be missed if they weren't included. You know, the household names that don't have the really big advertising bucks behind them. We ended up with a solid list of 13 brews. Of the 13, Sam Adams Light ranked numero uno. It was lauded for its discernable nutty flavor and relatively full body. One tester even noted that it "tasted like something I might find in a nice beer garden!" To find out which other tasty beers topped our list, check out the full report on the Best Light Beers in America.

BEST COCKTAIL

Old Fashioned

While booze shouldn't be part of your daily weight loss diet, downing a drink every now and again won't throw you far off track — so long as you order smart. Every Mad Men fan knows that Don Draper favors the Old Fashioned. And just so long as you don't sip them to his level of excess, the 119-calorie low-sugar drink can keep you on the track toward your better body goal. Not a fan of whiskey? Check out these other delicious, low-calorie cocktails.

BEST CAFFEINE SOURCE

Cold Brew

When regular brewed coffee is chilled and stored, two things happen: First, it begins to lose whatever nuance of taste it once possessed; second, it starts losing the polyphenols that give coffee its health benefits. The best iced coffee is cold brewed; it takes more time to make so it will be more expensive, but you'll taste the difference. Most notably it will be less bitter, which means you can get away with adding less sugar. And less sugar = fewer calories.

BEST DRINK IN AMERICA

Water

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 will take care of all your hydration needs.
