The Claim
Genetically determined higher post-challenge insulin secretion is positively correlated with body mass index (BMI), and this correlation suggests a causal role for insulin in promoting adiposity independent of diet or behavior.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People with genetically higher insulin levels after eating tend to have higher body mass index, and this relationship indicates that insulin directly contributes to fat accumulation regardless of diet or physical activity.
See the scientific wording
Genetically determined higher post-challenge insulin secretion is positively correlated with body mass index (BMI), suggesting a causal role for insulin in promoting adiposity independent of diet or behavior.
When insulin levels rise after eating, it tells fat cells to stop breaking down stored fat and start making new fat from sugar. This effect lasts for days, even after insulin levels drop, so fat keeps accumulating instead of being burned for energy.
What the research says
1 studyStudy: Why hyperinsulinemia is detrimental to weight loss: insights from type 1 diabetes
When your body releases more insulin after eating, it tells your fat cells to stop burning fat and start storing it—even if you eat the same amount as someone else. This study shows insulin can shut down fat burning for days, which helps explain why some people gain weight more easily.
