Tag: Smoking and metabolism

Medically speaking, pure nicotine is a calorie-free chemical compound. Contrary to popular myth, nicotine does not provide the body with energy in the form of calories, though its use is often linked to weight control. This association stems from nicotine's effect on appetite and metabolism, not from any caloric content it possesses.

According to numerous studies, adult smokers tend to weigh, on average, 4–5 kg less than their non-smoking counterparts due to nicotine's metabolic effects. This fact, however, does not mean smokers need to eat more, but rather eat significantly better to address nutritional deficiencies and long-term health risks caused by smoking.
