The Claim
In adults with upper-body obesity and/or type 2 diabetes, insulin-mediated suppression of adipose tissue lipolysis occurs independently of increased phosphorylation of Akt at serine 473/474, indicating the existence of Akt-independent regulatory pathways for lipolysis in human adipose tissue.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults with upper-body obesity or type 2 diabetes, insulin reduces fat breakdown in adipose tissue even when the Akt protein at serine 473/474 is not more phosphorylated, demonstrating that insulin can control fat breakdown through pathways that do not involve Akt.
See the scientific wording
In adults with upper-body obesity and/or type 2 diabetes, insulin’s suppression of adipose tissue lipolysis does not correspond to increased phosphorylation of Akt at serine 473/474, suggesting insulin may regulate lipolysis through Akt-independent pathways in human adipose tissue.
Insulin stops fat breakdown in fat cells by directly controlling proteins that guard fat stores, even when the usual signaling protein Akt is not activated. This control happens at the final step where fat-breaking enzymes are turned off, not through the typical insulin pathway.
What the research says
1 studyStudy: Adipose Tissue Resistance to the Antilipolytic Effect of Insulin and Niacin in Humans With Obesity.
In people with obesity or diabetes, insulin stops fat from breaking down even when a key protein (Akt) isn’t more active — meaning insulin must be using a different trick than scientists thought to do this job.
