New Jersey Gov. Chris Christie has enjoyed approval ratings over 70 percent since his handling of Hurricane Sandy. He has always been a fairly popular Governor, but he is also one of the more overweight politicians to get near the national stage, a fact his critics rarely fail to bring up. It is something Christie is aware of as well, since his obesity might very well cut his political career short. He remains healthy to date, but even he acknowledges that if he doesn’t do something soon, one of the rising stars of the Republican Party might set too soon. This, amid a time when overweight and obesity costs the United States some $60 billion in extra health care costs a year.
