Rochester, N.H. ? As doctors warn more patients that they should lose weight, the advice has backfired on one doctor with a woman filing a complaint with the state saying he was hurtful, not helpful.

Dr. Terry Bennett, of Rochester, says he tells obese patients their weight is bad for their health and their love lives, but the lecture drove one patient to complain to the state.

“I told a fat woman she was obese,” Bennett says. “I tried to get her attention. I told her, ‘You need to get on a program, join a group of like-minded people and peel off the weight that is going to kill you.’ “

He says he wrote a letter of apology to the woman when he found out she was offended.

Her complaint, filed about a year ago, was initially investigated by a panel of the New Hampshire Board of Medicine, which recommended that Bennett be sent a confidential letter of concern. The board rejected the suggestion in December and asked the attorney general’s office to investigate.

Bennett rejected that office’s proposal that he attend a medical education course and acknowledge that he made a mistake.
