The medifast diet is a very safe and effective diet and weight loss program. The main reason for this is because it gives enough nutrition while at the same time induces your body into a mild fat-burning state.
What is the Fat-Burning State?

When you are on the Medifast 5 & 1 Plan, your daily calorie intake is very low at around 800 to 1,000 calories. This causes your body to enter a fat-burning state - a "mild ketosis". In this state, your body’s fat releases free fatty acids, which are transformed by the liver to an energy source - the ketones. This mild fat-burning state helps the body achieve fast weight loss while preserving muscle tissue. It also helps eliminate physical hunger and provides sufficient levels of energy at the same time.

The fat-burning state is not harmful to your health. It is just a normal way that your body uses to manage energy. You get enough protein intake on the Medifast 5 & 1 Plan so that you are protected from losing muscle tissue. Regular exercise also helps in this area.

Are you in a fat-burning state?

You will know that you are in the fat-burning state if you feel less hungry and more energized, and start losing weight at a steady rate. It usually takes about 3-5 days, after you start the medifast diet, for you to move into the fat-burning state.
