Elevated circulating levels of branched-chain amino acids (BCAAs) and fatty acids (FAs) induce insulin resistance and metabolic dysfunction by promoting mitochondrial dysfunction and activating pro-inflammatory signaling pathways (NF-κB and NLRP3).
High levels of BCAAs and fatty acids in your blood are linked to insulin resistance and inflammation, which drive metabolic diseases. This often happens when your body struggles to process these nutrients (common in obesity or T2D) rather than just from eating them. Focus on improving metabolic flexibility and insulin sensitivity through exercise and balanced nutrition rather than assuming high BCAA/Fat intake is always beneficial.
The increased levels of BCAAs and fatty acids can lead to mitochondrial dysfunction by altering mitochondrial biogenesis and adenosine triphosphate (ATP) production... BCAAs can directly activate the mammalian target of rapamycin (mTOR) signaling pathway to induce insulin resistance... elevated levels of BCAAs and fatty acids can activate the canonical nuclear factor-κB (NF-κB) signaling pathway and inflammasome and regulate mitochondrial dysfunction and metabolic disorders through upregulated inflammatory signals.
Why this rating
This is a review paper summarizing multiple mechanistic studies; while not a single clinical trial, the consensus of cited literature is strong.

More from this paper
- Saturated fatty acids (SFAs) promote inflammation and insulin resistance by activating the NLRP3 inflammasome and NF-κB pathways, whereas unsaturated fatty acids (UFAs) like EPA/DHA can inhibit these pathways.Good
- BCAAs can stimulate mitochondrial biogenesis via the eNOS/NO/SIRT1/PGC-1α and mTOR/YY1 pathways, but this effect is tissue-specific and can be overridden by high levels of saturated fatty acids which suppress PGC-1α.Good
