This is interesting, called Le Whaf it is food that you inhale rather than eating. It is pumped out of a machine that resembles a gold fish bowl and enables the user to “eat” as much as they want with hardly any calories. If the article is to be believed it is predicted to be the futuristic way of eating. It can be used for all sorts of flavours and even to wharf alcohol. I’m not sure I am convinced I think I would rather have that slice of cake, calories and all.
