PHILADELPHIA (CBS) — Many of us resolved to eat less and exercise more in the new year.

But some may be taking their New Year’s resolutions too far.

Most of us want to lose weight and tone up, but when someone starts counting every calorie, eating only certain foods, or skipping social events so they can hit the gym, help may be needed.

“If your friend is exercising two to three times a day and it’s every day,” says Kelly Pedrotty-Stump, exercise coordinator at the Renfrew Center in Philadelphia, the right thing may be “just addressing that you are concerned, that they could themselves sick or injured and lead to a lot of other complications.”

Pedrotty-Stump’s best advice: “Don’t ignore it, and share your concerns with the individual,” she says, addressing your friend’s behavior rather than her appearance and offering to help by becoming a diet or exercise  buddy to monitor the activity.
