Smokers Better off Stopping, Even if They Gain Weight
If you quit smoking and gain weight, it may seem like you are trading 1 health problems for another. But a new US study finds you are better off stopping smoking in the long run even with the weight gain.
Compared with smokers, even the quitters who gained the most weight had at least a 50% lower risk of dying prematurely from heart disease and other causes, the Harvard-led study found.
The study is impressive in its size and scope and should put to rest any myth that there are prohibitive weight-related health consequences to quitting cigarettes, said Dr. William Dietz, a public health expert at George Washington University.
“The paper makes pretty clear that your health improves, even if you gain weight,” said Dietz, who was not involved in the research. “I don’t think we knew that with the assurance that this paper provides.”
The New England Journal of Medicine published the study Wednesday.
The journal also published a Swedish study that found quitting smoking seems to be the best thing diabetics can do to cut their risk of dying prematurely.
The nicotine in cigarettes can suppress appetite and boost metabolism. Many smokers who quit and don’t step up their exercise find they eat more and gain weight, typically less than 10 pounds, but in some cases 3X that much.
A lot of weight gain is a cause of the most common form of diabetes, a disease in which blood sugar levels are higher than normal. Diabetes can lead to problems including blindness, nerve damage, heart and kidney disease and poor blood flow to the legs and feet.
In the Harvard led study, researchers tracked more than 170,000 men and women over 20 years, looking at what they said in health questionnaires given every 2 years.
All of the people enrolled in the studies were all health professionals, and did not mirror current smokers in the general population, who are disproportionately low-income, less-educated and more likely to smoke heavily.
The researchers checked which study participants quit smoking and followed whether they gained weight and developed diabetes, heart disease or other conditions.
Quitters saw their risk of diabetes increase by 22% in the 6 years after they kicked the habit.
An editorial in the journal characterized it as “a mild elevation” in the diabetes risk.
Studies previously showed that people who quit have an elevated risk of developing diabetes, said Dr. Qi Sun, 1 of the study’s authors. He is a researcher at the Harvard-affiliated Brigham and Women’s Hospital
But that risk doesn’t endure, and it never leads to a higher premature death rate than what smokers face, he said.
“Regardless of the amount of weight gain, quitters always have a lower risk of dying” prematurely, Dr. Sun said.
I stopped smoking cold turkey 42 years ago and managed my diet carefully and did not gain 1 pound. You can too!
