When you stop smoking many people experience weight gain and this is closely related to metabolic rate. When smoked, the heart rate accelerates and increases the metabolic rate, so it is that more calories are burned. When the snuff is left, everything returns to normal and this is what causes them to gain weight, especially if you eat the same or more due to anxiety.
As the metabolic rate is returning to its normal rhythm, you can increase the weight about 4-5 kilos, but this is relative and depends heavily on the individual.
Similarly, it notes that studies have shown that even a moderate weight gain during the first year after quitting, this does not necessarily lead to a substantial increase in long-term weight in most cases.
Generally those who quit smoking tend to lose weight last one year abstinence, and after the first three months weight gain slows considerably. This also has to do with the fact that you begin to engage in physical activity that was previously impossible for poor endurance.
In the event that the possibility of gaining weight to quitting is not an option to consider, there are ways to help prevent or minimize the rise in kilos.
First of all, the need for oral gratification that usually meet a cigarette should not be replaced with food or at least try to do it with very poor calorie foods.
On the other hand, keep the mind occupied as much as possible to avoid falling into the vice is essential, as well as more physical activity outside the gym (walk to the office, climbing stairs, walking up the pace, etc.). These attitudes make better sense of well being and also help to calm the oral anguish and hence weight gain.
