Anyone heard of it?

It was just mentioned on the radio. Apparently it's a diet made up by a girl who took bits of other diets. Not sure which bits but apparently she lost over 3 stone in 5 months

Can't actually find much about it or how it works. Anyone tried it or know anything about it? Is it another faddy diet? Can't imagine if it's made up by an average Jane that there is my science behind it besides copying other diets

I think I have seen it mentioned on here once before, but other than that I've never heard of it
