A certain type of brain chemical signal in the hunger center of fasted rats helps tell them to eat more.
Scientific Claim
Dopamine D1-like receptors in the ventromedial hypothalamus are involved in regulating feeding behavior in 24-hour food-deprived male Wistar rats.
Original Statement
“This suggests that VMH D1-like receptors contribute to the regulation of feeding behavior in fasted states.”

Assessment Explanation
Based on abstract only - full methodology not available to verify. The verb 'contribute to' implies mechanistic involvement without confirmed experimental control or causal design.
More Accurate Statement
“Dopamine D1-like receptor activity in the ventromedial hypothalamus is associated with altered feeding behavior in 24-hour food-deprived male Wistar rats.”
Evidence from Studies
Supporting (1)
Scientists found that turning on a specific brain receptor in the hypothalamus made hungry rats eat more, and turning it off made them eat less—proving this receptor helps control eating when rats are hungry.
