What You Need

• A glass of cold water is all you need to get started. There's no need to purchase any fancy equipment or meal plans. Ideally, the water you drink should be cold---around 50 degrees Fahrenheit. Carbonated and flavored waters will not yield the same results.
  
  

Drink Up!

• You should drink 64 ounces of water every day. That's eight 8-ounce glasses, or a half-gallon. The preferred method is to drink a glass of water 30 minutes before each meal and another glass during the meal. You should also drink at least two glasses during the day. Drink normally, do not gulp the water. You are allowed to eat the foods you normally would eat.
  
  

How it Works

• The theory behind the diet is that the body burns 12 calories as it warms the water from 50 degrees to body temperature. But drinking a full glass of water before a meal also causes you to feel fuller much faster, reducing calorie intake.
  
  

Results

• With just this one change, you can expect to lose up to 15 pounds over the course of a year. However, adding a healthy diet and exercise regimen can greatly increase the results.
  
  

Added Benefits

• Research has shown that proper hydration can help reduce the risk of certain cancers, such as breast, colon and bladder. Other benefits include enhanced mental clarity and improved digestion, and it may even slow the aging process.
  
  

Disadvantages

• As you increase your water intake, you will find yourself making more trips to the bathroom. Some people on the diet initially report feeling bloated, but the bloating subsides after a week or two.
