When I first quit. I did gain some weight also, but not I weigh about 17 pounds less than when I smoked.
I don't know how your sweet tooth is right now, but when we first quit smoking, getting a sweet tooth is not uncommon.
It is because when we smoked, it caused an interaction that caused our bodies to release their own stored sugars. When we first quit smoking, our bodies have a hard time doing this on their own causing our blood sugar to drop. This is what causes a lot of people's withdrawal symptoms, such as being tired, irritable and sweet tooth.
Another problem is that smoking released our own stored sugars within seconds. When we quit smoking and eat. It can take up to 20 minutes for the body to release sugars for energy when we eat and sometimes, especially when we first quit. We keep on eating when we shouldn't.
Maybe try smaller more frequent meals throughout the day. That may help. That's what I did. Also, I ate a lot of vegies. It may sound boring, but I used different flavored mustards as a dip, since mustard has almost no calories.
While gaining a few pounds may kind of suck in the begining of quitting. It does usually taper off and as I said I now weigh less.
Here's how bad smoking is though. You would have to gain 75 to 100 pounds to put the same strain on your heart as you did when you smoked.
Now that's something to chew on.
