Why Drink 8 glasses of water a day?

• Water naturally suppresses the appetite
• Water helps the body to metabolise or burn stored fat
  The kidneys need sufficient water to function properly. When kidneys aren't working at full capacity, some of the kidney's load is shifted to the liver. The liver's primary function is to covert (metabolise) the fat stored in the body into usable energy (this is how you lose excess fat). If the liver is doing some of the kidney's work, it can't work efficiently to convert as much stored fat, so more fat remains stored in the body, and weight loss slows or stops. For this reason, apparently an overweight person actually needs more water than a slimmer person (approx 200ml extra per 10 kg overweight).
• Water helps the body to eliminate waste
  While losing weight, there is more waste to get rid of (where do you think that metabolised fat goes?)
• Adequate water can prevent or relive constipation
  When the body doesn't get enough water, it gets what it needs from internal sources, including the colon, which leads to constipation. Normal movements return when the body has enough water.
• Water also helps prevent saggy skin that often follows weight loss.
  Shrinking cells are filled with water, making the skin clear, healthy and “plump”.
