You should not feel hunger for an extended period of time while on the protocol. It is normal to feel a bit “empty” but this should not equate to a hunger feeling. If you are on your first week of the protocol and you are hungry, this is likely due to inadequate fat loading – keep moving forward, eat lots of vegetables, and get through the first week. Generally hunger due to inadequate loading is gone after the first week. However, if you are close to your goal weight and become ravenously hungry, it is important to contact our support staff soon as you can so we can help you finish your round successfully.
