A 3-day diet mainly focuses on certain types of food commonly found in your current diet, that when mixed create reactions in the digestive system.  The chemical reaction that takes place will boost your metabolism, and increase the rate of fat burn for an extended period of time.

The 3 day diet plan is a limited calorie diet or a "low fat diet".  There have been instances where if followed correctly you may be able to lose 10lbs in just under 3 days.  After the 3 days has expired you will continue to eating normal and healthy for 4-5 days and not overeat.

During the 3-Day Diet, you may add many different condiments such as herbs, soy sauce, mustard and ketchup, lemon, vinegar etc.  The amount of liquid you should consume should be around 4 glasses of water and you are allowed to have diet beverages such as diet soda.

The types of food you consume really depend on the person.  Usually sticking with less fatty foods such as vegetables, grains, pasta and lean meats are a good idea.
