Easy! Calculate Insulin Resistance with Triglycerides

Determining the degree to which the body’s cells respond effectively to insulin, in conjunction with circulating levels of triglycerides, is a valuable diagnostic tool. This assessment often involves using the fasting insulin level and the triglyceride concentration in a specific formula to estimate insulin sensitivity.
