Are Grains Bad for Your Heart? While there has been a recent flurry of books and websites demonizing grains in every form, the scientific literature does not support this belief.

How to lose 100 pounds Have you ever wondered what happens to the “biggest losers” on reality TV shows? When the cameras stop rolling, do their incredible transformations stick? Not usually.

In most cases, the weight comes right back and, even six years later, their metabolism is slower than it was before they started filming. This is what…
