Smoking cessation often leads to weight gain, typically 5-6 kg, peaking in the first two years. Factors like exercise and age can influence this weight change.

Area of Science:

  • Public Health
  • Behavioral Science

Background:

  • Cigarette smokers tend to have lower body weight than non-smokers.
  • Smoking cessation is commonly associated with weight gain, a frequent concern for individuals attempting to quit.
  • This weight gain, though not negating smoking cessation's health benefits, can deter quit attempts.

Purpose of the Study:

  • To estimate the risk and duration of weight gain following smoking cessation.
  • To provide physicians with data to counsel smokers concerned about post-cessation weight changes.

Main Methods:

  • A literature review was conducted.
  • MEDLINE database search using keywords related to body weight changes after smoking cessation.

Main Results:

  • The highest risk of weight gain occurs within the first two years post-cessation, decreasing thereafter.
  • Sustained quitters gain an average of 5 to 6 kg.
  • Factors such as physical exercise, older age, higher baseline body mass index, and lower smoking rates mitigate the extent of weight gain.
  • Evidence on the permanence of this weight gain is conflicting.

    • Conclusions:

    • Weight gain is a common consequence of smoking cessation, with a predictable pattern and average magnitude.
    • Physicians can use this information to manage patient expectations and concerns regarding weight changes.
    • Further research is needed to clarify the long-term implications of weight gain after smoking cessation.
