Flavored H2O Staying hydrated is important when you’re trying to lose weight. Drinking plenty of 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. But if plain water bores you, spruce it up with fresh herbs, citrus fruits, and other low-cal flavor enhancers (sliced cucumbers work well too) to encourage you to drink up. Try our 25 slimming Sassy Water recipes to sip your way slim. 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! Try this low-sugar watermelon smoothie recipe. Iced Peppermint Tea This minty thirst quencher is super refreshing on a hot summer day, but it’s also a super-effective belly flattener. Peppermint helps your stomach process fat, ensuring even high-fat foods like burgers and steaks are digested quickly, which helps prevent bloat. 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. Try this slimming pineapple smoothie recipe. Green Tea Besides reducing your risk of cancer and heart disease, green tea benefits the whole body and contains catechins, antioxidants that studies show can help reduce belly fat. If you sip green tea before a workout, these compounds can also increase your fat burn during aerobic exercise. MORE: 5 Ways To Drink Green Tea For Weight Loss Dark Chocolate Shake Really?
