The Claim
In individuals with obesity, impaired insulin-mediated suppression of basal lipolysis precedes hyperglycemia and is a key early defect contributing to systemic insulin resistance, independent of adipocyte size or total fat mass.
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.
In people with obesity, the body's inability to properly stop fat breakdown in response to insulin occurs before high blood sugar develops and is a primary early factor leading to widespread insulin resistance, regardless of fat cell size or overall body fat.
See the scientific wording
In individuals with obesity, impaired insulin-mediated suppression of basal lipolysis frequently precedes hyperglycemia and is a key early defect contributing to systemic insulin resistance, independent of adipocyte size or total fat mass.
In obesity, insulin fails to shut down fat breakdown in fat cells after eating, causing too many fatty acids to spill into the blood. These fatty acids build up in the liver and muscles, where they form harmful molecules that block insulin's ability to signal cells to take up sugar. This happens before blood sugar rises, and it occurs even if fat cells are not larger or more numerous than normal.
What the research says
1 studyStudy: Lipolysis in Health and Disease: Pathways, Regulation, and Metabolic Consequences
This study says that in obese people, the body’s failure to stop fat from breaking down after eating happens before blood sugar goes up, and that this fat leak is a big reason why insulin stops working well — even more than how much fat a person has.
