When the body loses fluids , whether through sweating or low water intake, the risk of symptoms such as fatigue, low blood pressure, dizziness, confusion, or changes in urine color increases , warns Harvard Health Publishing.
But beyond avoiding dehydration, increasing your daily water intake can have a direct impact on appetite control, fat burning, digestive function , and mood, says Dr. Charlotte Norton, medical director of The Slimming Clinic.
Reduces the feeling of hunger
Drinking water before meals can be an effective way to reduce calorie intake.
“When the stomach fills with water, a signal is triggered to the brain that tells us we’re full. Furthermore, thirst is often confused with hunger,” explains Dr. Norton.
Stimulates metabolism
Various studies have shown that drinking around 500 ml of water can temporarily increase metabolic rate by up to 30%, which translates to greater calorie burning. “This thermogenic effect can promote weight loss,” the expert says.
Contributes to the elimination of fat
According to Norton, proper hydration promotes the breakdown of lipids and facilitates their elimination, without altering insulin or blood glucose levels. Therefore, it is considered an ideal complementary strategy for those seeking to reduce body fat.
Improves digestive function
Water is involved in all stages of the digestive process, from the production of saliva to the excretion of waste.
“A well-hydrated digestive system absorbs nutrients better, which prevents metabolic disturbances that can lead to weight gain,” warns the doctor.
Strengthens mental and emotional health
Hydration also plays a key role in brain function. “Water helps maintain concentration, stabilizes mood, and reduces anxiety.
“On the other hand, dehydration can increase stress, affect motivation, and hinder weight loss,” Norton explains.
