Water plays a crucial role in weight management by aiding digestion, regulating metabolism, and promoting feelings of fullness. Staying hydrated can help people avoid mistaking thirst for hunger, potentially leading to reduced caloric intake. Water is also essential for optimal physical performance, as even mild dehydration can impact energy levels and endurance during exercise. Moreover, drinking water before meals can facilitate weight loss by curbing appetite and promoting portion control, making it an essential factor in achieving and maintaining a healthy weight.
