The Medifast Diet program’s concept is a basic one. Frequent small meals with high levels of protein and low levels of carbohydrates put your body into a state called ketosis. With the frequent meals you have less of a chance of feeling hungry and breaking the diet.
Originally, Medifast was only available through physicians, that's where the name came from, now they can be bought on line and in stores with it easy to find Medifast discount codes to reduce the cost. The basic plan, called the 5 and 1 Plan, involves using Medifast’s meal replacements for five daily meals and consuming one main "lean and green" meal you prepare yourself that consists of a protein source and lots of vegetables.
