This tool estimates insulin resistance using two different methods: 1. HOMA-IR (Homeostatic Model Assessment for Insulin Resistance) and 2. QUICKI (Quantitative Insulin sensitivity Check Index). Both use two fasting laboratory values — glucose and insulin — to help you better understand metabolic health.
Note: This tool is provided for informational and educational purposes only and is not intended to diagnose, treat, cure, or prevent any disease. Results should not be interpreted as medical advice. Users are encouraged to consult a qualified healthcare professional for evaluation and guidance specific to their individual circumstances.
The underlying HOMA-IR method estimates insulin resistance from fasting glucose and fasting insulin values. When glucose is entered in mg/dL, the formula is HOMA-IR = (insulin × glucose) / 405. When glucose is entered in mmol/L, the formula is HOMA-IR = (insulin × glucose) / 22.5. HOMA-IR value above 2 implies insulin resistance.
For QUICKI method the formula is QUICKI = 1/(log(insulin) + log(glucose)). In general, QUICKI > 0.45 indicates a likely healthy individual. QUICKI between 0.30 and 0.45 indicates a likelihood of insulin resistance. Anything below 0.30 indicates a likely diabetic condition.

A new study shows that many anti-aging treatments—such as fasting, healthy eating, and certain medications—are most effective when started earlier in life. As we age, our bodies change, and some treatments may lose their impact. Healthy aging isn’t an afterthought. Take care of your body now—your future self will thank you. Read the published study in Nature.
This article highlights research in older adults showing that high insulin levels are linked to accelerated aging, while better insulin sensitivity may help slow it. It is a useful overview of how diet, metabolism, and aging interact in later life.
This article reports that exercise improved brain insulin sensitivity in older adults with prediabetes and may help reduce dementia risk. That makes it especially relevant to healthspan, since it connects insulin resistance with cognitive aging rather than just diabetes.
