Smokers vs. Non-Smokers: Smokers tend to have lower body weight, but heavy smokers might gain more weight. Reasons include metabolic effects, appetite suppression, and lifestyle differences.
Smoking Cessation: Quitting smoking can lead to weight gain due to decreased metabolic rate and increased appetite.
Body Fat Distribution: Smoking is linked to central obesity (fat around the waist), which increases health risks.
Public Health Concern: The combined effects of smoking and obesity pose a major public health challenge.
