Yes you do, if you don't want to do AAM, you need a signature off your Dr.
It's really nothing to worry about, your calories are still very low and you'll continue to stay in ketosis and lose weight. Enjoy having a small meal in the evening & it really shouldn't cause you any problems.
I'm currently doing AAM at the moment. I was a bit wary at first because I saw it as another obstacle before getting to goal. But honestly, all I've had so far and will be tonight (no meats in stock) is cottage cheese and lettuce with cucumber... absolutely lovely! I need to have a water to wash it down straight after as I crave more of the taste mind you... that helps a treat!
Don't worry about gaining or anything, its only for a week and then you'll be looking forward to the next AAM its good to chew again
