In people who are overweight or obese, higher levels of certain amino acids in the blood during diet changes are linked to the body clearing insulin more slowly and releasing more insulin when blood sugar rises — which might mean these amino acids affect insulin in ways not related to how sensitive the body is to it.

Diets high in protein or saturated fat do not affect insulin sensitivity or plasma concentrations of lipids and lipoproteins in overweight and obese adults.

Randomized Controlled Trial

Human

2014 Nov

The study looked at how high-protein diets affect insulin and found that when BCAA levels in the blood went up, the body cleared insulin more slowly and responded to sugar with more insulin, just like the claim says.

Similar Assertions

Even if you have more branched-chain amino acids in your blood, insulin still works the same way to stop your muscles from breaking down — adding these amino acids doesn’t make insulin any better at protecting your muscles.

Insulin helps stop your body from breaking down muscle, even if you have a lot more of certain amino acids in your blood than usual — it works no matter what.
