Try This 6 Flat Belly Drinks

The refreshing sips that'll keep your belly flat too.

That sweet drink may hit the spot for breakfast or happy hour, but it's not doing your waistline any favors. A 20-ounce packaged lemonade can contain 250 calories and 68 grams of sugar. Fortunately, there are plenty of refreshing sips that you can drink without guilt—and they may actually help you lose weight.

Here are 6 ways to quench your thirst without packing on pounds.

Flat Belly Drink: Flavored Water

Staying hydrated is important when you're trying to trim down. Sure, you can fool yourself into drinking more water, and research has proven that water helps your body maintain proper fluid balance, stops water retention (a big cause of bloated bellies), and even increases the feeling of fullness so you eat less overall.

Flat Belly Drink: Watermelon Smoothie

As long as they're made without sugary mixers like sherbet, smoothies are a guilt-free way to hydrate—and watermelon is a terrific, low-cal smoothie base. Not only is it a natural hydrator because of its water content, watermelon is also loaded with nutrients, including cancer-fighting lycopene, as well as an amino acid known as arginine. A study in the Journal of Nutrition found that arginine can decrease body fat and increase lean muscle mass, so whip up this 56-calorie metabolism booster and sip away!

Flat Belly Drink: Iced Peppermint Tea

This minty thirst quencher is super refreshing, but it's also a super effective belly flattener. Find out how to brew your own teas, and go for the peppermint tea, which helps your stomach process fat, ensuring even high-fat foods like burgers and steaks are digested quickly, which helps prevent bloat.

Flat Belly Drink: Pineapple Frappe

This blended pineapple drink tastes like a beach vacation in a glass—and it packs in two belly-flattening ingredients. A tablespoon of flaxseed oil adds monounsaturated fatty acids (MUFAs), proven belly flatteners, and pineapple itself contains bromelain, an enzyme that helps break down protein, ease digestion, and banish bloat.

Flat Belly Drink: Green Tea

Besides reducing your risk of cancer and heart disease, green tea contains catechins, antioxidants that studies show can help reduce belly fat. That's right: Green tea can actually help you lose weight. If you sip a little before a workout, these compounds can also increase your fat burn during aerobic exercise

Flat Belly Drink: Dark Chocolate Shake

Really? Yes, really. Chocolate—especially dark chocolate—helps you slim you down because it decreases appetite and lessens food cravings overall. However, at nearly 400 calories, this shake is more of a meal than a snack.

Smoothie Snack Pack

Put 1/2 cup skim or soy milk, 6 oz (80-calorie) vanilla yogurt, 1/4 cup dark chocolate chips, and 1 cup fresh raspberries plus a handful of ice OR 1 cup frozen raspberries in a blender. Blend for 1 minute, transfer to a glass, or eat with a spoon (387 calories).
