Staying hydrated is extremely important, especially when exercising regularly. Drinking at least two to three litres of water a day is recommended and it can have both short-term and long-term effects.
“This means your body expends more energy to increase the body temperature. And therefore, the more calories you burn overall.”
One 2014 study showed that those who drank 500ml of cold water experienced an increase in energy expenditure.
The 12 participants burned between two to three percent more calories than usual in 90 minutes after drinking the water.
The expert added: “Some people claim that drinking water before a meal reduces appetite.
The women experienced a reduction in body weight, body fat and body mass index.
They also reported a reduction in appetite throughout the day.
David added: “The recommended daily intake of water is around two litres each day; however, this is just a guideline and can often vary between each individual.
“For example, people who sweat more frequently or exercise more often, will need more water compared to those who don’t.
“Being continuously hydrated is also essential during workouts.
“If your muscle cells are dehydrated, the process of building muscle is slowed.
“Water dissolves electrolytes and distributes them throughout the body, reducing symptoms which can negatively impact exercise, such as cramping.
“In addition, water allows the body to sweat which maintains body temperature and decreases fatigue, which can allow you to work out longer therefore and burn more calories.”
The expert warns that water is not a replacement for meals.
He said: “You should continue to eat your daily calorie allowance while drinking around two litres of water per day.”
