“Although the first few cups will help hydrate you, research suggests there is a tipping point where these drinks become a diuretic and you lose more water than you gain,” he continued.
Michael spoke to Dr Stuart Galloway, a professor in Exercise Physiology from the University of Stirling, to reveal how much water is needed, how to avoid the negative effects of dehydration, and how drinking water with every meal may help lose weight.
“What specifically is water doing to your body and brain?” Michael asked.
Dr Stuart replied: “We essentially need water to undertake a number of processes in our body, and because were constantly losing fluid throughout the day, through breathing, sweating, urine losses, we need to replace that through water from drinks and foods.
“If we don’t replace that, we end up in a body water deficit and that means we often have impaired physical performance, some impaired mental performance, feeling of fatigue for example.”
