The Obesity Paradox, Part 1

The Obesity Paradox: when heavier means healthier and thinner means sicker; Dr. Hoffman interviews Dr. Chip Lavie, author of a controversial book that posits that sometimes those excess pounds may be not really all that bad. Is there also an “exercise paradox”? A “cholesterol paradox”? A “blood pressure paradox”? Can svelte be dangerous, especially for seniors? Is this new-think merely an excuse for doctors and patients to give up on healthy diet and physical activity? How can you tell if those extra pounds are OK, or do they pose a threat to you?
