However there was no scientific evidence that drinking copious amounts of water is necessarily good for us. Until now.
Researchers at Illinois University have published a paper, based on over 18,000 people, in the Journal of Human Nutrition and Dietetics which shows that drinking water does actually help you to eat less and have less sugar and cholesterol.
They found that drinking an extra three coups of water a day meant you consumed up to 200 fewer calories which equated to losing a pound of fat in two weeks, regardless of what you ate or how much you exercised.
Scientists are also getting excited about pre-loading; drinking half a litre of water 30 minutes before each meal. Working with overweight and obese patients those who pre-loaded with every meal lost over 9lbs over a twelve-week period.
Even the dietitians are convinced. Although some experts say it’s better to sip little and often as drinking it all in one go can dilute your stomach acids and effect your digestion.
Health conscious people and gym goers tend to drink enough but the rest of us probably don’t. And that can lead to dehydration and putting on weight. Personally I’m averse to carrying a bottle of water around in my hand like a fashion statement saying how health-conscious I am.
And it only needs to be tap water. Not your expensive “hacked out of a glacier and towed from Iceland” variety. I made that up but I’m sure I read it somewhere. Sales of bottled water are worth £2 billion in the UK and up 10% on last year.
Researchers at Loughborough University have found evidence that high-intensity running can help you lose weight by suppressing your appetite through chemical changes in the body. It lowers the levels of a hormone which makes you hungry and boosts one which makes you feel full.
