Since the mid-1970s, when Harvard published "The Nurses Study," we've been told women with waists over 40 inches raised their risk of early death by 40% vs. women who maintained waists in the 26-27 inch measure. Pounds add up. Studies show that obesity is starting earlier than ever. 18% of children ages 12-18 are reported as being obese and 66% of baby boomers (81 million born between 1946-1964) are either obese or overweight.
