Chewing gum with nicotine makes you feel less hungry and more full, so you might not want to eat as much.
Scientific Claim
Nicotine at doses of 1–2 mg reduces hunger and increases feelings of fullness in healthy young men of normal weight, suggesting it has an appetite-suppressing effect.
Original Statement
“Hunger and prospective food consumption were negatively associated with the increasing doses of nicotine, whereas satiety and fullness were positively associated with the increasing doses of nicotine (p < 0.05).”

Assessment Explanation
The study design supports causation, but the small sample size (n=12) and lack of full data warrant cautious probabilistic language. 'Reduces' and 'increases' are acceptable under the study's RCT framework but should be tempered with 'may' or 'likely'.
More Accurate Statement
“Nicotine at doses of 1–2 mg may reduce hunger and increase feelings of fullness in healthy young men of normal weight.”
Evidence from Studies
Supporting (1)
The appetite‐suppressant effect of nicotine is enhanced by caffeine *
The study found that chewing gum with 1 or 2 mg of nicotine made healthy young men feel less hungry and more full, even without caffeine — which means nicotine itself can suppress appetite at those doses.
