A recent study highlights another alarming consequence of smoking: an increase in abdominal fat that is associated with serious health risks. Published in the journal Addiction, the research found that both initiating smoking and a lifetime of smoking can contribute to elevated levels of visceral fat, which surrounds vital organs. Dr Germán Carrasquilla of the Karolinska Institute noted that while a small amount of visceral fat is normal, excessive amounts can lead to inflammation and chronic diseases, such as heart disease and type 2 diabetes.
The study employed Mendelian randomisation to establish a causal link between smoking and increased abdominal fat, suggesting that smoking cessation could indirectly reduce these health risks. Despite its strong findings, experts caution that other lifestyle factors may influence these relationships, as unhealthy habits often coexist.
Dr Carrasquilla emphasised the importance of quitting smoking despite uncertainty about whether stopping can diminish belly fat. He advocates for public health initiatives focused on the comprehensive benefits of quitting. Experts agree that while quitting can be challenging, support systems and stress-reducing activities like exercise can aid the process. Ultimately, the motivation to quit should stem from a desire for improved health and quality of life, rather than mere obligation.
