What 30 Days on a CGM Taught My Patients About Their Healthy Diet

Patients eating the same bowl of oats every morning were shocked to see glucose spikes to 9–11 mmol/L — identical to a chocolate bar — while their neighbours eating eggs and avocado stayed flat. The PREDICT studies show that glycaemic responses to identical foods vary dramatically between individuals. Wearing a CGM for 30 days is now something I routinely recommend to non-diabetic patients as a diagnostic tool.
