The Claim

In overweight and obese adults, elevated plasma branched-chain amino acid (BCAA) levels during dietary intervention are correlated with reduced insulin metabolic clearance rate (ρ = -0.18, p = 0.03) and increased acute insulin response to glucose (ρ = 0.15, p = 0.05), suggesting that BCAAs may independently influence insulin secretion and clearance beyond changes in insulin sensitivity.

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

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 plain English

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.

In overweight and obese adults, increases in plasma branched-chain amino acids (BCAAs) during dietary intervention are correlated with reduced metabolic clearance rate of insulin (ρ = -0.18, p = 0.03) and increased acute insulin response to glucose (ρ = 0.15, p = 0.05), suggesting BCAAs may influence insulin secretion and clearance independently of insulin sensitivity.

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

    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.
