Ketone Testing

Ketone and glucose readings can be graphed alongside food intake, exercise, and sleep notes to surface correlations such as identifying what caused a weight loss stall. The article identifies urine, breath, and blood testing as the three primary ways to measure ketones. Blood ketone measurement is described as the most accurate and most relevant available method. Switching to blood testing provides a far more accurate picture of actual ketone status in an adapted person. Urine ketone strips are presented as the cheapest and simplest ketone testing option. Blood ketone meters are the more accurate and appropriate monitoring tool once urine readings drop and full metabolic adaptation is complete. A ketone reading of 0.5 millimolars is the threshold displayed in the Cronometer interface. Repeated testing is most useful for identifying trends rather than interpreting isolated measurements. Urine measurements become less accurate over time as keto adaptation increases ketone utilization. Urine ketone test results can be misleading because they cannot distinguish exogenous from endogenous ketones. As keto adaptation deepens, urine ketone readings drop toward trace levels because the bod…
