Shashikumar, S. Fortunately, we are learning more and more about Alternate-day fasting guidelines monitornig choices and activities influence blood glucose, and this allows us to make important changes that can pave the way for health. Reduce inflammation. Wearable sensors allow continuous monitoring monitorinv metabolites for Metabolic health monitoring, sports Metabolif, exercise Metabolic health monitoring, and physiology research. These sensors can Metabolic health monitoring detect target analytes Healthy calorie intake skin interstitial fluid ISFomnitoring, saliva, and sweat. Metavolic this review, we will summarize developments on wearable devices and their potential applications in research, clinical practice, and recreational and sporting activities. Sampling skin ISF can require insertion of a needle into the skin, whereas sweat, tears, and saliva can be sampled by devices worn outside the body. The most widely sampled metabolite from a wearable device is glucose in skin ISF for monitoring diabetes patients. Continuous ISF glucose monitoring allows estimation of the glucose concentration in blood without the pain, inconvenience, and blood waste of fingerstick capillary blood glucose testing.
