We know we are supposed to make healthy lifestyle choices. But how much of an effect do choices like diet, exercise and non-smoking really have on our lifespan?

Smoking is a known health hazard for pregnancies. But being exposed to smoke in utero may follow a baby girl into her own pregnancy when she grows up.

Among smokers, a common reason to not quit is the fear of gaining weight. While weight gain is a serious concern, continuing to smoke is a greater concern.

Every year people make New Year’s resolutions, and every year it’s a battle to stick with them. Plan ahead, set up a support network and use good coping tactics to stay the course.

Scientists have not developed a foolproof way to quit smoking without gaining weight, but that’s no reason to keep smoking. Smoking has far greater health risks than the ten pounds you may gain.

There’s this myth out there that smoking helps keep the weight off. But recent science may have just proved that myth completely wrong.

Not everyone gains weight when they quit smoking but, unfortunately, about 84 percent do. Making the effort to not overeat for the first few months after quitting could help.

There's no better day than today to change your diet and quit smoking. Benefits from these lifestyle changes appear to take effect within months.
