How do ketone strips measure weight loss?
Asked by anonymous on Mar 05, 2007 in Weight Loss

My friend says ketone strips are a good way to measure if you are losing weight or not. How do they work?


Ketone test strips measure weight loss indirectly by checking for ketones in the urine. Ketones are produced when carbohydrates are severely restricted and the body breaks down stored fat and muscle for fuel. The loss of ketones is accompanied by the loss of water and so when ketone levels are high, water loss is dramatic. Ketosis and pronounced water loss happen at the start of very low carbohydrate diets. Any diet that raises ketone levels is considered to be radical and temporary.
