The Surprising Health Impact of Three Slices of Pizza, Explained by a GP.

Dr. Rangan Chatterjee, an NHS doctor and broadcaster, wore a continuous glucose monitor (CGM) to track his blood glucose levels after eating three slices of pizza and was shocked to see his reading shoot up to the highest level he had ever seen. He believes that if people could see the real-time effect of sustained spiking of their blood glucose, they might think before they eat. Chatterjee has signed up as an advisor to Levels, an app set to launch this summer that provides real-time feedback on how diet and lifestyle affect metabolic health by leveraging data from biosensors, such as CGMs.
