Why we cite it
An early trial of alternate-day fasting in 16 nonobese adults over 22 days, including a 57% reduction in fasting insulin. The authors found it ”feasible”, with a caveat: hunger on fasting days ”did not decrease, perhaps indicating the unlikelihood of continuing this diet for extended periods of time”.
