Here's the information about Ketosis.
Carbohydrates provide the majority of our energy for day to day functioning. When you eat carby things such as bread or pasta, your body converts the molecules into glucose a desirable fuel for your body.
On Medifast, the low carb content forces your body to look elsewhere for fuel. This is because we are providing limited sources of glucose for your body.(through carbs)
Initially the carbs that have been stored as "glycogen" in your muscle cells provide fuel to run on. But, after 2 - 3 days these stores are used up and your body must continue to look elsewhere. Eventually it begins to metabolize the fat stores and use them as energy. ( this is what we want!!)
Now the fat stores release molecules called "free fatty acids" into the bloodstream. These are transported to your liver where they are converted into "'Ketones" an energy molecule similar to glucose. Your liver routinely produces a small number of ketones but the influx of free fatty acids prompts the liver to go into overdrive. Then it realeses large numbers of ketones into the bloodstream where they are grabbed by your brain and muscle tissue and used for energy. (the ketones are providing energy and your body is not burning anything other than fat -- it's leaving muscle tissue alone--before this on program your body was burning glucose -- again not muscle)
Once you start M.F. it takes about 3 days to build a ketosis level high enough for your body to start using ketones as fuel. Once you reach that point you will probably notice you have more energy and less hunger.
The ketosis level you reach is not high enough to be tested however. It is a very very mild level of ketosisyet very affective at fat burning.
Now to eating extras -- . Dr. Anderson told us that one little crouton can put us out of ketosis.
It is a very delicate balance. Medifast is a medically balanced program
My advice to you would be to be totally compliant to plan, eat every 2 1/2 to 3 1/2 hours. Never go over 4 hours between meals. And realize every little thing you add (or deleat) causes real problems in the program. That is why we say "Don't mess with Medifast"

P>S. thanks for the review -- it was good for me to have to look someof these things up again -- refreshes the old memory.
