Smoking to Vaping
Do former smokers gain weight after switching?
Most people who transition from cigarettes to vaping either stay the same weight or shed a few pounds. The real weightgain spike tends to happen when nicotine is dropped entirely, not when its simply swapped for a vape.
Why quitting nicotine can add pounds
When you quit nicotine, your metabolism slows a bit and cravings for foodespecially sweetscan spike. Its a classic quit smoking, gain a snack scenario. The body is basically saying, I missed the nicotine, give me something else!
Personal story prompt
Imagine a vaper named Alex who quit cigarettes, started a 3mg nicotine vape, and logged his weight for three months. He lost 2kg in the first month (thanks to reduced cravings) and then held steady for the next two months. That little narrative can illustrate the typical pattern.
