Book Nook: 'South Beach Wake-up Call'

Agatston, whose original "South Beach" diet books have sold some 23 million copies, is a Miami Beach cardiologist whose nickname for today's young adults is sobering: "Generation S," he writes, "the sickest generation." A generation whose excess belly fat leads to inflammation, then "rusting" on the inside -- premature aging, heart disease and more.

But you can "rust-proof" your body with a proper diet, exercise and enough sleep.
