Ok, lol... stop the panic!
A tablespoon is a tablespoon... lol.. if you were reading from a recipe to make a cake (sorry) you would know what spoon to use right? To be honest though, even if you used a serving spoon for the veg, it won't make all that much difference. Seriously. It won't.
My losses have always been lower on AAM weeks because I was always generous with my measures and I didn't altogether stick to the list, however, the cost was a low loss, but the gain was, for me, a more satisfying meal. Now... it worked for me BUT it's NOT how you should do it. (I always stuck to the right amount of protein though).
AAM is just really there because the health guidelines state that you are not supposed to SS for more than 4 weeks continuously... so, whack in a teeny meal each day for 7 days and you fulfil the health criteria. Job done. The biggest bonus of AAM is, I think, that you get to handle and prepare food, and then you get the pleasure of enjoying every damn morsel! I can't tell you how long it took me to eat my very first AAM but it was a LONG time!! Teensy or not, I enjoyed every single scrap of it! lol It helps you to control your eating too, you have to measure and weigh and it gives you an insight into just how much we really eat when we think we are 'being careful'!
Enjoy your AAM week, plan it well and it will help loads. Have fun with this diet - it's a tool to enable you to ultimately achieve what you want to. I would definitely recommend you look at the thread with recipes for the packs and have a go at them. CD 'muffins' have been a life-saver for me! Also for a while the 'crisps' and 'biscuits'.
Lots of luck with it all, I'm sure it'll all come together great and that you will get into AAM no problems - it's like anything new, practice and you get better at it
Have a lovely day.
