One woman's story stuck with us.
For years, Karen did everything her friends suggested — gave up dessert, walked every morning — and still felt the afternoon crashes and the cravings that wouldn't quit. She'd started to believe it was just "her age."
Then a relative sent her the presentation above. About nine minutes in, the doctor said one sentence about that "sludge" — and she sat up…
…but the part that surprised her most is the part she says you really have to hear him explain yourself.
