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.
Your body releases cortisol when you smoke. Cortisol stimulates gluconeogenesis, meaning it makes your body form glucose. Glucose is a sugar and your body breaks food down into glucose for energy. So, when you experience a spike in cortisol you will also experience a spike in sugar.
There are a number of undesirable hormonal effects of nicotine as well. Tobacco influences fat distribution through hormones like cortisol that increase abdominal fat deposition. In women, nicotine has an anti-estrogen effect which also favors abdominal fat collection.
Nicotine reduces body weight by raising the resting metabolic rate while blunting the expected increase in food intake in response to the increase in metabolic rate.
For many people, quitting smoking can actually lead to weight loss. One reason for this is that smokers that quit actually lose belly fat in the long run, according to a recent study. In one trial, smokers quit with the help of their doctors and smoking cessation drugs.

Smoking and body shape
In smokers, more fat is stored around the waist and upper torso and less around the hips. This means smokers are more likely to have a higher waist-to-hip ratio (WHR) than non-smokers.
Nicotine acts as a stimulant, which raises your metabolic rate, speeding up how quickly you burn calories. Cutting out nicotine will reduce these metabolic spikes, slowing the body's fat burning rate. Nicotine suppresses appetite by inhibiting the body's expectation of food to make up for energy spent.
