Surprising Findings
Nicotine didn’t alter leptin levels despite its known appetite-suppressing effects in humans.
It’s widely believed nicotine reduces hunger by boosting leptin—this study found no such effect in rats, even under chow restriction, which should amplify metabolic signals.
Practical Takeaways
Don’t assume nicotine-based products (like patches or gum) will help you lose weight if you’re eating the same amount.

Nicotine acts as an appetite suppressant via central nervous system activation of hypothalamic satiety pathways independent of tobacco-derived toxins.
Giving young rats nicotine through a pellet didn't change their leptin hormone levels, whether they had eaten or just drunk sugar water.
Even when young rats got nicotine, they didn’t gain more or less weight than rats that got a fake pellet — as long as they all ate the same amount of food.
When young rats were given sugar water, their blood sugar, insulin, and fat levels didn’t change whether they had nicotine or a fake pellet.
