"Smoking's effect on body weight could lead to weight loss by increasing the metabolic rate, decreasing metabolic efficiency, or decreasing caloric absorption (reduction in appetite) all of which are associated with tobacco use. The metabolic effect of smoking could explain the lower body weight found in smokers."
"Smoking affects and alters our metabolism " . Decreasing metabolic deficiency . That's another warning that should be put on packaging . Anything that we use that alters who we are meant to be is a warning sign . When I smoked , my energy seemed high , when I quit smoking, I noticed my metabolism slowed . So I wanted to learn more about it. I suggest reading the resources in full if you are interested .
"In the short term, nicotine increases energy expenditure and could reduce appetite, which may explain why smokers tend to have lower body weight than do nonsmokers and why smoking cessation is frequently followed by weight gain. In contrast, heavy smokers tend to have greater body weight than do light smokers or nonsmokers, which likely reflects a clustering of risky behaviors (eg, low degree of physical activity, poor diet, and smoking) that is conducive to weight gain. Other factors, such as weight cycling, could also be involved. In addition, smoking increases insulin resistance and is associated with central fat accumulation. As a result, smoking increases the risk of metabolic syndrome and diabetes, and these factors increase risk of cardiovascular disease. In the context of the worldwide obesity epidemic and a high prevalence of smoking, the greater risk of (central) obesity and insulin resistance among smokers is a matter of major concern."

Besides its metabolic properties, nicotine could induce an acute anorexic effect: during a 2-h period, hunger food consumption were negatively associated and satiety and fullness were positively associated with increasing doses of nicotine (28). In both smokers and nonsmokers, nicotine did not change hunger sensations but resulted in smaller caloric intake during a meal (29). However, caloric intake was higher during a meal after nicotine administration than after placebo (30). Finally, physical activity increases metabolic rate and may help to control body weight, but smokers tend to be less physically active than nonsmokers .

Cigarette smoking increases a person's metabolic rate slightly by forcing the heart to beat faster. Regular smoking increases the heart rate both in the short-term (up to 20 beats per minute) and throughout the day (average increase, seven beats per minute).2 This causes extra stress on the heart and plays a role in heart disease, the most common cause of smoking-related death.
When you stop smoking and your heart rate slows down, so does your metabolic rate. While shifts in metabolism, along with dietary changes, can signal a slight weight gain after you quit smoking,3 you can take steps to build your metabolic rate back up in ways that benefit your health.

Smoking and your health: the thyroid Mayo blog is another good resource with information ...sorry do not know how to attach the link but just type it into the research engine or if someone can do that that would be helpful .
I highly recommend reading the links . Distract a crave , educate . Have a super grateful day .
