It’s recommended that men consume about 15.5 cups of fluid daily, while women need around 11.5 cups. However, you may need to increase your water intake if you are trying to lose weight—especially because it’s important to replace the fluids you lose through sweat during exercise. Besides physical activity, your fluid needs also depend on your climate, medical history, and diet.
Drinking water may support weight loss by boosting your metabolism and controlling your appetite. It is important to replace high-calorie drinks with water.
Supports Your Metabolism
Drinking water can speed your metabolism, which is how your body uses energy. A faster metabolism may help you burn more calories and lose weight more effectively.
Decreases Empty Calories
Consider replacing calorie-dense drinks, such as soda, juice, or tea, with water. Opt for water to lower your overall calorie intake for weight loss.
Helps You Avoid Overeating
The timing of when you drink water can also help with weight management. Drinking a glass of water before your meals can help you feel fuller and more present. This can lower your risk of overeating.
May Contribute to Your Nutrient Intake
Part of your daily water intake also comes from the foods you eat. Fresh fruits and vegetables have a higher water content, which helps you stay hydrated. It also provides fiber and other essential nutrients.
Water is crucial for health, but it is not the only factor in weight loss. It can help you feel full and decrease your overall calorie intake.
However, water alone will not burn fat. You may not lose weight if you drink enough water but take in more calories than you burn.
Sustainable weight loss requires a holistic approach. You need a balanced diet, regular physical activity, adequate sleep, and stress management.
Increasing your water intake may seem simple, such as adding an extra glass of water between meals or before bed.
However, there are fun and easy ways to help you drink more water, such as:
- Add flavor: Pieces of fruit, vegetables, or herbs can add sweetness or spice. Try lemons, limes, melons, strawberries, cucumbers, jalapeño slices, or mint leaves for variety.
- Drink from a fun cup: Just using your favorite cup or bottle can make drinking water more enjoyable. Choose one with your favorite color or design.
- Track your intake: It is easy to lose count of how many glasses of water you drink. Use a journal or an app to track how much water you drink each day.
- Set reminders: You might not realize that you are thirsty or that it is time to drink water. Use an alarm on your phone to remind you.
There are many ways to stay hydrated and meet your weight loss goals. Consult a registered dietitian to understand your daily water needs. They can help you create habits that fit your lifestyle and health objectives.
