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

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

A strong combo of nicotine and caffeine made some people feel sick, but even when those people were removed from the data, the appetite-suppressing effect still held up.

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

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