Packet egg whites are fine BUT cost more than buying eggs and "losing" the yolks; sad but true!
Gravy granules definitely not.
Ketchup in teeny quantity from Cruise ok but you'd be better making your own to leave yourself some leeway with certain other ingredients which might be iffy...
Ref your chocolate comment - it is not OK! It's a tolerated item from Cruise only, 1 teaspoon maxi per day, and it needs to be a fat free sugar free version thereof! (It's yuk!)
Lemon - he says a drizzle on fish or in a recipe for flavour not for using as a drink addition. (I forgot this rule myself in Jan, and had some juice each morning in my first glass of water. Stalled my weight loss!!)
Extra lite Philly save for when you're desperate. Not at outset. It's an iffy one cos he says OK in the UK from Cruise in small quantities, then brings out recipes using large quantities (to be eaten over the month?!!), but again it really doesn't fall into the "rules" he gave us. So wait for that one until desperate!!
