The Claim
Elevated levels of free fatty acids and intramyocellular lipid metabolites, including diacylglycerol and ceramides, are associated with mitochondrial dysfunction and activation of serine kinases that impair insulin signaling in skeletal muscle and liver.
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.
High levels of certain fat molecules in muscle and liver cells are linked to reduced mitochondrial function and disrupted insulin signaling pathways.
See the scientific wording
Elevated levels of free fatty acids and intramyocellular lipid metabolites such as diacylglycerol and ceramides are associated with mitochondrial dysfunction and activation of serine kinases that impair insulin signaling in skeletal muscle and liver.
When too much fat enters muscle and liver cells, it overwhelms the energy-producing parts of the cell, causing them to leak harmful molecules called reactive oxygen species. These molecules turn on specific enzymes that attach phosphate groups to insulin signaling proteins at the wrong spots, blocking insulin’s ability to tell the cell to take in sugar. This leads to sugar building up in the blood.
What the research says
1 studyStudy: Role of mitochondrial dysfunction in insulin resistance.
When too much fat builds up in muscle and liver cells, it creates harmful byproducts that mess up the cell’s energy factories (mitochondria) and block insulin from telling cells to absorb sugar. This study shows that when mitochondria don’t work right, insulin resistance happens — which matches the claim.
