Ginger slightly raised a hunger hormone called ghrelin after eating, but this wasn’t strong enough to be certain, and it didn’t change the active form of the hormone.
Scientific Claim
In overweight men, total ghrelin levels were numerically higher after ginger consumption compared to placebo, though this difference was not statistically significant in the full sample and showed no effect on active ghrelin or AUC.
Original Statement
“Total ghrelin levels tended to be higher in the ginger phase than in the control phase (P = 0.059). ... No significant difference was found for active ghrelin levels between phases (P = 0.45).”

Contradicting (1)
The study didn’t even measure ghrelin, so it can’t say whether ginger raises it or not—so the claim about ghrelin levels isn’t backed up by this research.
