Many people tend to put on some weight when they quit smoking.
There are two reasons for this.
1. Nicotine actually speeds up our metabolism. So, you need to eat 100-200 less calories a day or exercise more.
2. Nicotine causes a dopamine release as does food so you are trying to replace the dopamine feel good feeling with food..
Recent Studies Say:
Looking at pictures of food releases as much dopamine as actually eating the food.
Thinking of the food before you eat it is when the dopamine is actually released, not after you've eaten it.
Put this realization into practice and there is no need to be so concerned.
Look at pictures of foods you think you are craving and instead of eating them, munch on some cardboard. (I'm kidding about the cardboard)
