I'd take it easy on trying to game the plan... you don't have much to lose, and if you are still feeling like you aren't getting enough food, try using the unlimited veggies for that, because really, that's what you need to learn for maintenance.
Extra protein can be converted to glucose and stored, so loading protein is not the answer. And one week is not an adequate amount of time to judge results from a specific way of eating.
Just concerned that you seem to be a little manic about this, jumping into a tweak already. If you don't like the sweetness of the restricted, then don't eat them, choose something else, but don't try to game it to lose faster. Your body is already efficient at using the food put into it when you are close to goal. YOU
WILL LOSE SLOWER than someone with 50 or more pounds to lose. It's scientifically inevitable. It took me 3.5 months to lose 30 lbs without gaming it. Honestly, it's a very short time period in our lives. It takes longer to learn healthy mindful eating for maintenance. Have patience, my friend
