From: Training to estimate blood glucose and to form associations with initial hunger
Estimated vs measured blood glucose of trained subjects with levels below 87 mg/dL at the final session. The highest glycemic value measured in trained hungry subjects was 87 mg/dL. Below this value of measured blood glucose, 18 subjects reported to be hungry (hollow red circles) and 14 subjects were not hungry (filled red squares). Linear regression is significant for the hungry subjects (dashed red line; r = 0.92; p = 0.0001) but not for those not hungry (solid red line; r = 0.18; p = 0.54).
