In the study, after one year, 83 percent of the keto diet group was still following the program, and 94 percent of that group was able to reduce or eliminate their insulin dosage. Overall in that group, study authors saw an average A1C percentage decrease of 1.3 percent, with 60 percent returning to prediabetes status, and an average weight loss of 12 percent, with the average participant losing 30 pounds after a year. The study authors found “no significant changes” in A1C or diabetes medication use in the ADA diet group. The ADA group also didn’t lose weight, the authors say.
What Should People With Type 2 Diabetes Take Away From the Study?
Kelly Kennedy, RD, staff dietitian at Everyday Health, says the A1C reductions noted in the study are impressive but notes the research isn’t perfect.
Namely, the study wasn’t double-blinded, where neither the study authors nor the study participants know which group is the control and which is the experiment. This aspect would have eliminated potential bias among the participants and authors in this study, Kennedy says. Not to mention, Virta Health’s telemedicine app was the primary application used, so the company stands to benefit from positive study results — another factor that could’ve led to bias in the way the findings were presented.
