The Claim
Despite decades of research, there is a profound lack of direct human data on leptin signaling dynamics in lean and obese individuals, whereas there is extensive characterization of insulin action in type 2 diabetes.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Scientists know a lot about how insulin works in people with type 2 diabetes, but they still don’t have much direct information on how leptin behaves in the bodies of lean or obese people—even after many years of studying it.

What the research says
1 studyStudy: Leptin physiology and pathophysiology: knowns and unknowns 30 years after its discovery
This study says that even after 30 years of studying leptin, scientists still don’t fully understand how it works in people’s bodies, especially when comparing lean and obese individuals—unlike insulin, which we know a lot about in diabetes.
