Chewing gum with nicotine makes you feel less hungry and more full, so you might not want to eat as much.

When caffeine is added to nicotine gum, it makes the nicotine work even better at making you feel less hungry and more full.

A moderate amount of nicotine with caffeine doesn’t make people feel sick and still helps reduce hunger, making it a good balance.

Nicotine acts as an appetite suppressant via central nervous system activation of hypothalamic satiety pathways independent of tobacco-derived toxins.

People who smoke tend to weigh less than non-smokers, and when they quit, they usually gain about 4 kg because their body goes back to how it normally weighs without nicotine.

Researchers asked people how hungry or full they felt using a simple line scale after giving them gum with nicotine and/or caffeine.
