Fat-Burning State & Weight Loss


  • What is the Fat-Burning State?
    On the Medifast 5 & 1 Plan, your body enters a fat-burning state -- also known as “mild ketosis.” The nutrient balance of Medifast in combination with its low calorie level causes the body’s fat stores to release free fatty acids, which are then converted by the liver into an energy source called ketones. This mild dietary fat-burning state helps the body achieve rapid weight loss while preserving muscle tissue. The fat-burning state also helps eliminate physical hunger while providing sufficient levels of energy.



  • Is this Fat-Burning State harmful to me?
    No, the fat-burning state achieved on the Medifast 5 & 1 Plan is very mild. The fat-burning state is a normal adaptive mechanism that your body uses to manage energy. The level achieved will protect you from losing muscle tissue (due to the amount of protein that can be consumed on the Medifast 5 & 1 Plan). Incorporating regular exercise also helps to tone and build muscle tissue.



  • How long does it take to get into the Fat-Burning State?
    It generally takes about 3-5 days to get into the fat-burning state.



  • How can I tell I am in the Fat-Burning State?
    The best way to determine if you are in the fat-burning state is by recognizing physical clues -- such as feeling less hungry and more energized, and losing weight at a steady rate.



  • Can I use ketone test strips?
    Medifast does not require ketone testing. The best way to determine if you are in the fat-burning state is by looking for physical reactions -- such as feeling less hungry and more energized, and losing weight at a steady rate.
