Vaping can be used to battle obesity, according to research, as studies have found that e-cigs help ex-smokers keep the pounds off that are often gained after quitting tobacco.

It is widely known that nicotine suppresses appetite and increases metabolism, so it’s unsurprising that quitters put on an average of 5kg in the first year after stopping smoking cigarettes.

To battle the weight gain, nicotine replacement therapies, such as gum and patches, are often utilised. However, researchers believe that vaping will be the best method of keeping weight off.

“People can change their nicotine content, so to quit smoking they might start off on a higher strength e-liquid and then they can taper down really quite gradually in a much more sophisticated way than they can with NRT, which is probably good for weight maintenance and for weight loss,” said Linda Bauld, professor of health policy at the University of Stirling and deputy director of the UK Centre for Tobacco and Alcohol Studies.

It has also been theorised that the array of e-liquid flavours available actually prevent vapers from snacking on cakes and sweet foods. This has been argued by several vapers who use flavoured e-liquids to cure addictions to sweets.

The massive declined in smokers over the last few decades have been linked to increasing levels of obesity. E-cigs could help halt that and stop smokers from gaining weight.

It certainly makes sense as a viable nicotine replacement strategy. Research has found that e-cigarettes do not produce an oxidative stress response like regular cigarettes, and are considered the best method of quitting smoking.

“People can change their nicotine content, so to quit smoking they might start off on a higher strength e-liquid and then they can taper down really quite gradually in a much more sophisticated way than they can with NRT, which is probably good for weight maintenance and for weight loss,” added Bauld.

“We are not suggesting that we should promote e-cigarettes to people who haven’t smoked. But for people who are thinking about the best way to stop smoking and are concerned about weight gain, I think what we are suggesting is that e-cigarettes should certainly be considered.”
