The Fat-Burning State & Weight Loss

What is the fat-burning state?
On the Medifast 5 & 1 Plan, the amount of protein you eat is comparable to that found in a typical American meal plan. However, the amount of carbohydrates is less compared to what may be typically consumed. On the 5 & 1 Plan, an individual can expect to take in less than 100 grams of total carbohydrates per day (generally in the range of 75-95 grams total). This lower level of carbohydrates, coupled with the reduced calorie level of the Medifast 5 & 1 Plan, allows your body to enter the fat- burning state, also known as a very mild "dietary ketosis." This 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 faster weight loss while helping preserve muscle tissue. The fat-burning state also helps naturally reduce appetite and hunger while still allowing you to feel 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 three to five days to get into the fat-burning state if you're following the 5 & 1 Plan recommendations.
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.
