There is some evidence to suggest that vaping can affect weight gain, although the extent of this effect is not fully understood.
Nicotine, which is commonly found in vaping products, has been shown to suppress appetite and increase metabolism in some studies. This could potentially lead to weight loss or a decrease in weight gain over time.
However, other factors related to vaping could also play a role in weight gain. For example, some people may use vaping as a substitute for other habits, such as snacking or eating unhealthy foods, which could contribute to weight gain. Early signs show that it can aid in reducing weight.
