Your gravy would be more like 2.5 syns i'm afraid.
Like everyone else says, you need to eat more superfree. I'd be having a massive salad with that lunch (& probably only having either tuna or beana, but thats personal preference).
Your weetabix is fine, unless its the chocolate ones, in which case use as a heb & add 2 syns as well. But definitely add the superfree in. My breakfast is more fruit with cereal thab cereal with fruit, if you get me.
It does work, just takes a bit if getting used to.
I recommend you read the sticky thread on extra easy as it explains the plan really well.
