WE ALL HAVE A FRIEND WHO SEEMS TO EAT EXACTLY WHAT SHE LIKES and stay stick-thin and another who only has to look at a muffin and she’s gained a pound. Sometimes these differences are noticeable even within the same families.

Until now, scientific evidence has been lacking on why the same foods can have different effects on individuals, or on what might cause these different responses.
