The Claim

Healthy vegans have a higher baseline insulin sensitivity than omnivores, as measured by glucose infusion rate during hyperinsulinemic-euglycemic clamps (9.6 ± 2.4 vs. 7.1 ± 2.4 mg/kg/min).

In plain English

People who follow a long-term plant-based diet show higher insulin sensitivity than people who eat animal products, as measured by how efficiently their bodies use glucose during a controlled metabolic test.

See the scientific wording

Healthy vegans exhibit higher baseline insulin sensitivity than omnivores, as measured by glucose infusion rate during hyperinsulinemic-euglycemic clamps (9.6 ± 2.4 vs. 7.1 ± 2.4 mg/kg/min), suggesting long-term plant-based diets may enhance glucose disposal capacity.

Why this might work

People who eat only plants have less fat buildup in their muscles because their bodies store excess nutrients more efficiently in fat tissue. This keeps their muscle cells responsive to insulin, allowing glucose to enter easily and be used for energy. As a result, their bodies clear sugar from the blood more effectively than those who eat meat.

1 study
  1. Study: Chronic dietary exposure to branched chain amino acids impairs glucose disposal in vegans but not in omnivores

    The study found that people who eat only plants naturally process sugar better than meat-eaters, even before taking any supplements — their bodies respond more strongly to insulin. This difference was clearly measured and confirmed in the data.
