The Claim
Fasting insulin levels, when combined with BMI, improve the predictive accuracy for low handgrip strength in women, indicating that insulin provides additional discriminative value for metabolic risk stratification beyond body weight alone.
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 women, measuring fasting insulin along with BMI provides a more accurate prediction of low handgrip strength than BMI alone, showing that insulin levels add useful information for identifying metabolic risk beyond body weight.
See the scientific wording
Fasting insulin levels improve the prediction of low handgrip strength when combined with BMI, particularly in women, suggesting that insulin adds discriminative value to metabolic risk stratification beyond body weight alone.
High insulin levels over time cause muscle cells to stop responding properly to signals that build and maintain muscle. This leads to less energy production, more fat buildup inside muscle fibers, and increased inflammation, all of which weaken the muscle and reduce its ability to generate force.
What the research says
1 studyThis study found that when women have higher insulin levels, their hand strength tends to be weaker — even if they’re not overweight. So measuring insulin along with BMI helps spot muscle weakness better than BMI alone.
