Is Body Weight Linked With Smoking?

Introduction and Background

In order to be able to live a normal life, it is absolutely important that our bodies keep on functioning normally. Every single aspect of our lifestyle needs to be kept in check in order to make sure that nothing goes wrong. Since the body itself is a complex network of interconnected systems, everything has an impact on everything. In simple words, if we harm one part of the body, the whole body suffers eventually. One of the biggest concerns nowadays for people all over the world is the impact that an abnormal body weight could have on the functioning of the body. While the answer to that is that it isn’t good, there are also a number of different reasons why your weight would become normal to even begin with. The factors that cause an abnormal body weight need to be examined individually in order to distinguish what is good and what isn’t. One of these factors that we will discuss here today is smoking. What impact does smoking really have on a person’s body weight and what are the things that you need to know? To find out the answer to that question, keep reading.

Overall impact of smoking

Putting body weight aside, it is important that we first determine the fact that smoking is not good for health in any way. The amount of harm it brings to the body, especially the lungs and the respiratory system as a whole is something that must be given special concern. You need a healthy respiratory system to sustain your body’s strength and smoking can completely destroy it over the period of time and that is not a cost anyone should pay for a mere taste of something that is nothing but a combination of hundreds of dangerous chemicals.

Link between smoking and body weight

Several studies have been conducted by different organizations around the world, including World Health Organization, to study the impact that smoking has on the weight of a person’s body. A number of different results were generated and they have been discussed here.

Each study group had three parts; heavy smokers, light smokers and non-smokers. The main focus was to measure metabolic rate of the body in relevance with the amount of smoking a person was doing. The results were gathered in terms of the amount of body weight that was gained by each group.

Heavy smokers showed the least amount of body gain over a given period of time. After that came the light smokers and the most weight gain was shown by non-smokers. The result was determined by the fact that smoking either decreased the metabolic efficiency of the smokers or increased its activity overall.

While this may show that smoking is good for maintaining body weight. It was also a very clear observation that heavy smokers were the most obese among the groups and the reason determined for that was their inability to lose weight using other methods.

Another study however, produced a very different and much more revealing result. Smokers in that study all gained weight over time and the reason was that they had become used to a lifestyle that wasn’t providing the body with any reason to move around. The smokers tended to keep resting, relaxing and doing nearly zero physical activities and had also gotten involved in other weight gaining activities like excessive food intake and drinking.


While there may be an instance or two where smoking may help in retaining weight, it is very visible that in the long run, the whole body adapts to a lifestyle that makes you gain extra weight. Add to that the countless other negative impacts that smoking has on the body and you can easily determine that smoking is not good, both for the body weight and in general.
