i suppose there would be no harm in having another mousse, its the same as having 2 bars in one day, better to have 2 bars or 2 mousse than have a cheat meal! i think they say to restrict it because of the gelatine though, it may not be great for overall weight loss if you had 2 mousses every day but if its a one off then what's the harm?! what you could do is add a bit more extra water and only eat half. when i did this last night it was much bigger than usual, although it took a while to set so ended up putting it in the freezer which i should have just done in the first place anyway! i only got thru half so i've got the rest when i get home! yummy!
