Sustained lipid mobilization (fat loss) leads to the disassembly of caveolae through the degradation of cavin proteins (cavin-1, cavin-2, EHD2), reducing caveolae density.
When you lose fat, your fat cells physically change structure. This paper shows that as fat is burned, the 'caveolae' structures on the cell surface break down. This is a natural adaptation to smaller cell size.
StrongSupportsMEDIUM confidence
Lipid mobilization in cultured adipocytes to induce lipid droplet shrinkage led to biphasic response of cavin-1 with ultimate loss of expression of cavin-1 and -3 and EHD2 by protein degradation, coincident with caveolae disassembly.
Why this rating
Strong mechanistic evidence from cell culture and mouse fasting models.
