This 2018 trial, funded by Virta Health, tested the impact of a high-compliance ketogenic diet on metabolic outcomes in Type 2 diabetics. At the end of the one-year trial, nearly half of all subjects were able to discontinue their diabetes medication, including 40% of those taking insulin. Sixty percent of participants had reduced their HbA1c to <6.5% and were off all diabetes medication or down to metformin only at the end of the study; they therefore no longer met the criteria for diabetes on the basis of HbA1c. This trial represents the first clear, long-term evidence in a large population that a ketogenic diet, when followed properly, can lead to significant improvements in health among Type 2 diabetics, and in many cases (in this trial, the majority) even resolves diabetes completely.
