Starting your day with a glass of water kickstarts your metabolism and can help control your appetite. That's because staying well-hydrated throughout the day supports your body's ability to metabolize fat efficiently. Studies show that drinking water before meals can also make you feel fuller, reducing the chances of overeating. Aim for at least eight glasses of water daily for optimal hydration and digestive health. "Staying well-hydrated is crucial for overall health and can help control your appetite, prevent overeating, and support metabolism," says Best.

 8 Best Drinks for Weight Loss

Green Tea

Green tea is a metabolism-boosting powerhouse due to its high catechin content. These natural antioxidants promote fat oxidation, improve insulin sensitivity, and support healthy weight management. Additionally, the moderate caffeine content in green tea can provide a gentle energy boost, making it an excellent alternative to sugary, calorie-dense beverages. "Green tea contains antioxidants and compounds like catechins, which may help boost metabolism and increase fat oxidation," states Best.

Lemon Water

Lemon water is packed with vitamin C, which supports your body's fat oxidation process. Drinking warm lemon water in the morning can kickstart your metabolism and promote a sense of fullness, potentially preventing overeating later in the day. "Lemon water is low in calories and can help with digestion and detoxification," says Best. "It also adds flavor to plain water, making it more enjoyable to drink."

According to a 2021 review, ginger tea can soothe an upset stomach, alleviate bloating, and reduce inflammation in the digestive tract. These benefits support a flatter belly by preventing digestive issues that can cause temporary distention.

Cucumber-Infused Water

Cucumber-infused water is more than just a spa-day favorite; it can be a helpful tool for maintaining hydration and managing weight. Cucumbers are made up of over 95 percent water, making this infusion highly hydrating. Additionally, they contain compounds that may help control appetite, potentially reducing overall calorie intake. "Cucumber-infused water is refreshing and low in calories," says Best. "It can help you stay hydrated and may have a mild diuretic effect."

Peppermint Tea

To incorporate ACV into your routine, dilute a tablespoon in a large glass of water and consume it before meals. "Some people claim that ACV can aid in weight loss and reduce belly fat when consumed in moderation. Mix it with water or use it in salad dressings," says Best.
