Someone gets a tidbit of diet information from a friend. Mind you, said friend could be nyone from a high-performance athlete on a very specialized diet to a person who is completely full of crap. They’ll then take that advice to heart. But they’ll absorb other advice too, and add that into the mix. Before you know it they’ve built a Frankenstein dietĀ from popular advice, half-truths, and dieting myths and will wind up more or less the same as when they started.
