the same amount of time as that piece of string !! Everyone looses at different rates , the average is 14 lb a month but a lot of people have a big loss in the first week so that speeds it up , I lost 5 stone in 4 months , but when i got down to the last stone it slowed down so as a rough guide i would say 5 months .
ketosis is the state your body goes into when it has to break down your body fat for energy . Normally your body uses the carbs you eat as energy , as exante is a low carb diet you dont have enough , and once all your carb stores are used up ( about 3-5 days ) your body has to start finding the energy somewhere else , and starts using the stored fat . Hope that helps x
