Fat friends and friends of the fat, a new future awaits us. Today, one-third of America — grown-up America — is obese. About 17 percent of our children and teens are also obese, which is triple the rate from a generation ago. If we triple again, we will all be obese. Even conservative estimates predict that by 2030 about half of men and women in the U.S. will be obese. However you look at it, big times are ahead.
