Cigarettes can have complex and varied effects on weight, influenced by both physiological and behavioral factors. While smoking is often associated with weight loss or weight management, the relationship is not straightforward and comes with significant health risks.

How Cigarettes Affect Weight

Appetite Suppression: Nicotine, the addictive substance in cigarettes, acts as an appetite suppressant. It affects the brain’s hypothalamus, which regulates hunger, leading many smokers to eat less and consume fewer calories.

• Increased Metabolism: Smoking can slightly increase metabolic rate. Nicotine stimulates the release of adrenaline, which can raise heart rate and calorie expenditure, contributing to weight control for some smokers.
• Behavioral Patterns: Smokers may use cigarettes as a coping mechanism to deal with stress, boredom, or emotional triggers, replacing food with smoking to avoid weight gain. This behavior reinforces the belief that smoking helps with weight management.
• Changes After Quitting: Weight gain is common after quitting smoking, as former smokers often experience increased appetite, slower metabolism, or a tendency to substitute food for cigarettes as a reward or stress reliever. On average, people gain 5-10 pounds after quitting, but this varies widely.

Risks of Smoking for Weight Control

Using cigarettes to control weight is highly dangerous. Smoking poses severe health risks, including lung disease, heart disease, cancer, and premature aging. The slight metabolic boost or appetite suppression from smoking does not outweigh the devastating health consequences.

Additionally, smoking can have indirect effects on body composition and fitness. Long-term smoking reduces lung capacity and cardiovascular health, making it harder to engage in physical activities that help maintain a healthy weight. Smoking can also lead to muscle loss and decreased bone density, contributing to overall poor health.
