Core Viewpoint - Increasing water intake can positively impact weight management by reducing overall calorie consumption and enhancing satiety, as supported by multiple studies and systematic reviews [3][4][5]. Group 1: Benefits of Drinking Water for Weight Management - Drinking water does not directly cause weight loss but aids in weight control through various mechanisms [5]. - Replacing sugary beverages with water can lead to a reduction in body mass index (BMI) by an average of 0.31 [2]. - Participants in studies who increased their water intake lost an average of 0.33 kg compared to control groups, with those replacing sugary drinks with water losing up to 0.81 kg [3]. - Additional water intake can enhance weight loss by 44%-100% for overweight and obese adolescents and adults [4]. Group 2: Mechanisms of Action - Water occupies space in the stomach, reducing the intake of other high-calorie beverages [6]. - Drinking water before meals can decrease food intake by 22%, with studies showing that consuming 500 ml of water before meals can lead to a reduction of 74 kcal at breakfast and 60 kcal at lunch [6]. - Adequate hydration is essential for metabolic processes and fat burning, acting as a carrier for nutrients and waste [7]. Group 3: Recommended Water Intake - The latest dietary guidelines suggest that adults in moderate climates should consume at least 1500-1700 ml of water daily, which translates to approximately 6-8 cups [9][10]. - Individual water needs may vary based on activity level and environmental conditions, with adjustments recommended for high temperatures or increased physical activity [10]. Group 4: Healthier Drinking Habits - Prioritizing plain water and unsweetened tea is recommended, while sugary drinks should be minimized [12]. - It is advised to drink water regularly throughout the day rather than waiting until thirsty, especially for older adults who may have reduced sensitivity to thirst [13]. - Special circumstances, such as intense exercise or illness, may require increased water intake, potentially including electrolyte solutions [14].
